Please join me on this extraordinary journey, you won’t regret it. Two episodes ago we found out that ants are farmers, at least some species of ants are farmers and they are amazingly well organized and productive farmers. The other side of sustained food production is ranching. Ranching is a form of agriculture focused on raising livestock for various uses. Are ants ranchers? Let’s find out! The eighth thing I like about ants is their ranching activities. For those of you listening in order, last episode we learned about the Weaver ants of Africa that live in trees. They are some of the coolest ants out there with special physical adaptations  and behavioral adaptations that help them survive in the tree. One of the activities I didn’t talk about, because I was saving it for this episode, is their ranching. The weaver ants, Oecophylla longinoda, use other insects as a form of food resources. Now they do hunt other insects and tear them apart and eat the bits, but they also corral certain insects and use the honeydew that those insects produce as food. Mealy bugs, plant hoppers, and scale insects are some of the “cattle” that Weaver ants utilize. These insects are all sap-sucking species that tap a plant for it’s sap and drink it. The ants love the honeydew, or doo-doo, that comes out the other end of these insects. Yes, that’s correct, the ants are eating their excrement which is actually more nutritious than nectar.  The Weaver ants are protective of their livestock keeping them from harm and moving them to fresher pastures, just like human cowboys. They often build leaf tents over and around their charges keeping them hidden from predators and controlling their movements so they can gather the honeydew for as long as the insect lives.  Who knew ants were ranchers? It’s not only Weaver ants that exhibit this behavior.  Some species of Formica ants are also ranchers. They will tend similar insects as the Weavers including Mealy bugs, plant hoppers, scale insects as well as whiteflies and aphids. I found several papers talking about the relationship between Formica ants and aphids. They really treat these aphids like humans treat cattle. The ants tend them, watching them to protect them from predators, they will pick them up and remove them from a plant when danger arises (okay humans can’t pick up cattle, but we can escort them to another area when needed), and when the part of the plant that the aphids are eating from begins to run dry the ants will take them to greener pastures. The ants are after the honeydew, of course, the excrement from the aphids, just like the Weaver ants. It is high in concentrated sugars and carbohydrates that keep the ants running.   Giant ants, Camponotus gigas, from the t

Some we’ll find right out side our doors and some are continents away but all are fascinating.  This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it. We are rounding the bend with the ants series and there is no better way to do that than to take to the sky. The title of this episode is Arboreal Ants. There are ants that live in trees and never touch terrestrial earth their entire lives. You thought the Leafcutter ants were amazing, well hold on to your hat because the seventh thing I like about ants is the colonies that live in the trees. Arboreal ants, which are ants that live in trees, are found on many different continents and there is more than one species, but we are going to focus on one species in particular so we can really see their amazing qualities in detail. We’re spending some time with the Weaver ants of Africa, Oecophylla longinoda. Now living in a tree for an ant is no small feat, so how do they do it? Terrestrial ants dig into the dirt and create many chambered nests. It’s kind of difficult to dig into  a tree, so where are arboreal ants living? Weaver ant nests are most common in the outer, uppermost branches of trees where the sun light is bright. Here, the ants will bind adjacent healthy leaves together to create a treetop tent. The size of each nest will vary but is often between the size of baseball or a volleyball. They are as light as an inflated ballon and can withstand wind, rain, and enemy invasions. To begin building a nest, a worker ant will pull the edge of a leaf toward the edge of another leaf. If her bending is successful other workers will come to her aide.  Now weaver ants get their name from the next step. To keep the leaves together they employ their larvae. If you’re think, “What?” I hear ya! The larvae are picked up by workers and taken to the edge of the leaf connection. The workers tap the larvae on the leaf to encourage the larvae to release silk. Yes, the larvae of many species of ants create silk. The Weaver ants use this silk to secure the leaves together. The motion of shuttling the larvae back and forth to connect the leaves with the silk is where the weaving comes in. The nests may last for years because when one leaf dies the ants will just weave in another living one.  The nests are larger enough to house thousands of ants, but the weaver ants don’t have just one nest in the tree. They travel all over the tree that they call home, so they often build other trees  op tents so they can maximize their resources. They don’t stick to one central nest, they have the ability to move around when they need to. One territory can have multiple nests. The queen is often in a nest that is the most centralized to the territory, but her eggs are distributed throughout all the nests. With all of these spread out workers, Weaver ants have to have an excellent communication strategy. And boy, do they! Earlier we learned that pheromones are integral to ant communication. It’s the same with weaver ants, but they have a specialized gland that helps the pheromones that they use to create their paths last longer than terrestrial ants. They have an anal gland that helps them make their poop a bit more than just poop. To keep their pathways from wearing away t

Summary? Can ants be farmers?

Please join me on this extraordinary journey, you won’t regret it. Can ants be farmers? In this episode we are going to find out. The sixth thing I like about ants is their farming abilities. You may have heard of leafcutter ants. These are ants that cut leaves and carry them back to their colony. They are often highlighted in nature television programs. It’s mesmerizing and charming watching a line of ants traveling with various sizes of leaf pieces held above their heads. Leafcutters will fall into one of two genera: Acromyrmex and Atta. There are 39 species that we currently know of and they are all found in the New World. Atta are most prevalent in the tropics of South America but there are two species that can be found in North America, one in Texas and Louisiana and one in Arizona.  Leafcutter ant nests can extend 7 meters, or 22 feet, into the earth and contain eight thousand chambers. The largest chamber is typically the ant waste chamber which is buried as far down as they can make it. The title of this episode is farmers so how does that relate to our leafcutter ants? Well, leafcutter ants are farmers. I used to think that they cut those little pieces of leaves to eat themselves, but that is not what they are doing. They take the leaves back to their nest where they feed it to fungus. They tend the fungus like farmers and then they eat the fungus, or rather the larvae eat the fungus. So I guess every leaf cutter ant eats the fungus at some point in their life.  The adult workers ants eat the sap from the leaf fragments that they cut. This is what energizes them to process the leaves. The leaves have to be mulched first before it is fed to the fungus. The fungus will grow and grow and grow in the leafcutter nest. It will fill up the majority of the chambers with a lightweight spongy structure that kind of looks like a human brain and is called a fungus garden. The ants tend the fungus by adding new leaves to the top and sides while they removed the older bottom portions.  It is unusual that ants are completely dependent on vegetation, but leafcutter ants are. The fungus is actually high in protein and that helps the larvae grow big and strong.   The largest nest that Mark Moffett ever came across during his studies was in the Kaw Mountains of French Guiana. The above ground soil mounds were chest high and ranged over a 14 meter wide area. It ranged over about 160 square meters in total. If we compared this to a human made structure, it would be bigger than the Empire State Building in New York City. This nest probably housed millions of workers.  A nest of this size can require an excavation of 40 tons of soil. It must house the queen, the brood, and the workers but even with millions of ants it’s the fungus gardens that take up most of the real estate. The ant population can weigh up to 15 to 20 kilograms and utilize 280 kilograms of leaves. That’s enough plant matter to blanket a soccer field. Now, this is a lot of living things inside an enclosed space, so it gets hot and humid. To combat increasing heat and humidity which slows down fungal growth, the ants have installed air conditi

Summary: Let’s talk ant anatomy! Join Kiersten as she discusses basic ant anatomy, as well as a few unbelievable anatomy specializations.   For my hearing impaired followers, a complete transcript of this podcast follows the show notes on Podbean   Show Notes: “Ant Body Structure” - Harvard Forest: https://harvardforest.fas.harvard.edu “Ant Anatomy” - Ask a Biologist, Arizona State University: https://askabiologost.asu.edu/explore/ant-anatomy “Tales from the Ant World” by Edward O.

Some we’ll find right out side our doors and some are continents away but all are fascinating.  This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it. So far we have talked about some extraordinary ant behaviors and we have so much more to explore, but I thought we should look at an individual ant before we move forward. The fifth thing I like about ants is their anatomy. Ants are classified as insects, so they have three body parts: head, thorax and abdomen. They have an exoskeleton made of chitin. Chitin is the second most abundant amino polysaccharide polymer found in nature. It is hard and protects the internal organs of insects and gives their body structure.  The head of an ant typically hosts two compound eyes, two antennae, two mandibles and a mouth on the outside while internally it houses the brain. Many species also have ocelli in the middle of the head, as well. The compound eyes contain hundreds of lenses that combine to form a single image. Species that use vision to hunt for prey will have larger compound eyes, while those that rely on other senses will have smaller compound eyes. All species of known ants have antennae, typically two. The antennae will be constantly moving as the ant tastes, touches, and smells everything it comes in contact with. The antennae will bend in the middle like a human elbow allowing maximum flexibility. Mandibles are super important to ants and they will vary by species. Some of them are extremely specialized and we will go through a few of those species in a moment. In general, mandibles are used to grasp anything ants need to pick up or carry. They are also used to bite, crush, cut, dig, fight, and hunt. Just behind the mandibles is the mouth which is used to eat, clean themselves, and groom nestmates. The last item on the head is the ocelli. Ocelli are simple eyes that detect light. Ant head shape will vary greatly between species and that is dependent on what they eat and how they build nests. The second segment is the mesosoma. Now, I just said ants have three segments and the second segment was the thorax, right? I did and this is technically correct, but the last two segments aren’t clearly visible. The mesosoma actually contains the thorax and the front of the abdomen. The mesosoma segment is full of muscles and is where the legs attach to the ant’s body. Ants have six legs. Their legs are made for movement and most ants can run fast when needed. Each leg has four segments and a hooked claw at the end of each leg helps the ant climb and hang onto surfaces. The third segment is the abdomen which is made up of the petiole and the gaster. This is the segment that contains all the important internal organs that keep the ant alive, besides the brain which is located in the head. The heart, the digestive tract, and the chemical weaponry is all found in the gaster. The chemical defense system will vary by species. Ants can have a stinger with which to inject venom into p

Summary: Did you read that title right? Yes, you did. Some ants make slaves of other ants! Join Kiersten to find out how.   For my hearing impaired followers, a complete transcript of this podcast follows the show notes on Podbean   Show Notes:  “Tales from the Ant World” by Edward O.

Some we’ll find right out side our doors and some are continents away but all are fascinating.  This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it. In the last episode we talked about communication and how pheromones allow ants to give each other important messages and instructions. This is an amazing adaptation that makes them one if the most efficient organisms on the planet, but it does have a downside. Relying on pheromones as your main source of communication can lead to loop holes that others will take advantage of and by that I mean enslavement. Yep! Some ants enslave other ants. It’s not exactly something I like, but it is incredibly interesting. So, the fourth thing I find interesting about ants is how they use and misuse pheromones to their greatest advantage. We discussed how ants know who is allowed to come in and out of a colony in the last episode. When ants emerge from their pupal stage their body oils absorb the unique smells of their colony. This gives them the key to re-enter their colony when they venture out, and it helps protect the colony from intruders, but it can also be used to enslave them.  Let’s find out exactly how this works. The workers of ant species specialized to be slave-makers will raid colonies of other species. Workers from Polyergus lucidus or Formica subintegra will raid the colony of a vulnerable species such as Formica subsericea. When they raid the colony they have one target, the pupae. The adults of the colony being raided certainly put up a fight and ants on both sides of the battle will lose their lives but the raiders will retrieve at least some of the pupae they were after. That pupae is taken back to the raiders colony and settled in with the nursery there. Within a few days or weeks, the raided ants will emerge and soak up the scent of their new colony. They believe this is their home. It’s where they are meant to be. They accept the raiders as their sisters and the raiders accept them as their own. So, the enslavement isn’t like what we think of from the human perspective. It is a bit more like capture and domestication of wild animals. In the north temperate zones of North America, Europe, and Asia ant slavery is common especially in the subfamily Formicinae. Oddly, slavery is known in only temperate areas. Five species of Polyergus ants are known to be slave-makers and these ants range across North America, Europe, Russia, and Japan. All of them enslave ants in the genus Formica.   Let’s follow a specific raid detailed by Mark W. Moffett in his book Adventures Among Ants. At Sagehen Creek Field Station in the Sierra Nevada of the United States, Moffett and his graduate student watched a raid between Polyergus breviceps, also known as Amazon ants, and Formica argentea. The Amazons were raiding the Formica colony. They watch as the Amazons forced their way inside the Formica colony and then head out the other side with the pupae of the Formica. They flipped a rock to find out what was going on inside and expected to see a war going on between the raiders and the Formica, but that is not what they saw at all. The only fight they saw was one Formica ant in a tu

Please join me on this extraordinary journey, you won’t regret it. I feel like we have already talked about so much cool stuff about ants and we are only on episode three. This is going to be quite an exciting series on ants. The third thing I like about ants is how they communicate. Most of us have probably seen a line of ants moving from one place to another at some point in our lives. We may have stopped to take a look and wonder what they were doing or just walked on by without too much of a second thought.  Either way, your brain probably took a moment to puzzle over what they were doing, where they were going, or how they knew where to go.   Communication is the key! So, how do ants communicate? Two types of chemical substances lead ants through their lives. Pheromones which are chemical substances passed back and forth between individuals of the same species and allomones which are chemical substance used by other species and used by social invertebrates to hunt prey or avoid being prey. A quote from Edward O. Wilson about ant communication states, “Among all of the organisms that live by smell and taste, ants are the virtuoso of chemical communication.” End quote. Just a heads up, of you haven’t already figured this out, I will be quoting E.O. Wilson a lot in this series, but he’s learned so much about ants and he is always eager to share that I just can’t help myself. Ants have created a unique chemosensory world that no other creature known to humans can surpass.  Let’s look first at how those ants traveling in a line know exactly where to go? When an ant colony needs resources they send out scouts to find what they need. When a scout finds what they want, they eat or drink their fill and run back to the nest in as straight a line as possible. The scout always knows where her nest is regardless of how far away they have traveled (we will discuss this in a moment). When she arrives at the nest, the scout will puke all over the floor. No serious, she will gurp up a small portion of what she ingested in front of a few ants and then turn around an head back. Some of her sisters will immediately follow her out. But why? She just came in the house threw up all over the floor and then left! What is going on?  When that scout regurgitated the resource she found she created a pheromone that simply stated, “I’ve found what we need! Here it is! Follow my trail to find more!” Who can resist an invitation like that? The original scout laid a scent trail for herself by dragging her stinger along the ground to follow back to the resource and now her fellow workers will also follow that trail to help gather more of what they want. E.O. Wilson encourages you to experiment with some sugar water to see this phenomenon for yourself. You can use a drop of sugar water near a line of ants and watch what happens when they find it! Please use common sense if you choose to do this. Be careful to keep yourself and the ants safe from harm. How do ants identify these chemical signals? Do they have a nose to sniff them out? Sort of. They do not have a nose like a mammal that sticks out on the

Please join me on this extraordinary journey, you won’t regret it. On to episode two of ants, listeners! The second thing I like about ants is the life of a colony. I had no idea how complicated the life a colony was when I started researching this topic. Each species of ant will have specifics that differ based on how they obtain resources and where they choose to live, but the basic structure of the life cycle of a colony is essentially the same for all ants. It all begins with a virgin queen. When a colony reaches a certain size, and that size varies with each species, the current queen will lay an egg, or several, that will develop into a new young queen. She will develop wings, and as soon as she is able, will take flight from the existing colony. Her first flight is also her nuptial flight. She will emerge form the colony structure and alight on a leaf or rock and release a pheromone that says “Hello! Here I am!” And the males will come flying. Typically they want to mate with males of a different colony, but when males are scarce they will mate with males of their own colony. Diverse genetics is not something most insects have to worry about like mammals must. Depending on the species, the queen will mate with one or multiple males. Regardless, the queen will mate only once in her life. Sometimes mating takes place in the air and sometimes it takes place on that leaf or rock. Either way, they will each go their separate ways once the deed is done. The queen will wonder off looking for the perfect place to start her new life while the male, having completed the only thing he was born to do, will die or become food for a predator. Sorry, gentleman. For the new queen, no longer a virgin but with a spermatheca full of sperm (a quick aside: a spermatheca is a pouch in the abdomen where queen ants store the sperm obtained during mating) she follows her instincts to find the best home for her new colony. Based on species it could be a rotten log, a perfect dirt mound, a tree branch, or any number of other places. If she survives the nuptial flight, and that is a big IF, and she finds the perfect colony-building site, another big IF, she will break off her wings and settle in to begin pumping out eggs.  It can take a queen anywhere from 24 hours to a week to lay eggs. The first eggs laid will be the first workers in the colony, so…they will be female. That’s right! It’s a woman’s world in the ant universe. Disney Pixar’s A Bug’s Life  is wrong, it would have been a female ant that saved the day while the males just laid around doing nothing! All working ants in a colony are female. And here comes the harsh truth about the males: According to E. O. Wilson, one of the foremost authorities on ants in the world, quote “Adult males, with the exception of competing for access to virgin queens, and the food and grooming they receive from their sister workers, are pathetic creatures.” End quote. Males have small brains and big genitalia. They are only necessary during the nuptial flight and mating success is not guaranteed, only death is g

Some we’ll find right out side our doors and some are continents away but all are fascinating.  My name is Kiersten and I have a Master’s Degree in Animal Behavior and did my thesis on the breeding behavior of the Tri-colored bat. I was a zookeeper for many years and have worked with all sorts of animals from Aba Aba fish to tigers to ravens to domesticated dogs and so many more in between. Many of those years were spent in education programs and the most important lesson I learned was that the more information someone has about a particular animal the less they fear them. The less they fear them the more they crave information about them and before you know it you’ve become an advocate for that misunderstood animal. This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it. This is the beginning of a new series about a misunderstood animal that every one of us has encountered. Ants. Ants are one of the most misunderstood animals on the planet but they are so fascinating and very successful. In this series we are going to find out what makes them tick. The first thing I like about ants is their origins. As I begin this series I actually have a red, angry fire ant bite on my thumb. The irony is not lost on me that I am about to embark on a ten episode series dedicated to lauding the amazing attributes of ants to lure you into loving them while I have an itchy, painful welt from an ant bite on my thumb. These animals are truly fascinating so I bet I can get you to fall in love with them despite the nasty bites we’ve probably all experienced. Let’s get started from the beginning shall we? The classification of ants is as follows: Kingdom Animalia (Animals) Phylum Arthropoda (Arthropods): invertebrate animals that have a segmented body and jointed appendages Subphylum Hexapoda (Hexapods): a six-legged arthropod  Class Insecta  (Insects) Order Hymenoptera (Ants, Bees, Wasps and Sawflies) Superfamily Formicoidea (Ants) Family Formicidae (Ants) The scientific names will vary based on species. When did ants first appear on the planet?  They have been on the planet between 100 -150 million years ago. The specific timing has been hotly debated for many years until and amber sample was found by some rock hounds in 1966. This sample was discovered in Cliffwood Beach, New Jersey in the United States. It seemed an unlikely place to find what scientists needed to determine the origins of ants and it took twenty more years after the initial discovery to clarify whether this sample was of an ant or not. In 1986, it was confirmed to be the amber fossil of an ant solidifying the origins of ants in the mid-Cretaceous period, 90-94 million years ago. By the mid-Eocene period, approximately 50 million years ago, ants had achieved their current level of abundance. How many ants are on the planet today? In the summer of 2018, Edward O. Wilson, one of, if not the, foremost experts in the study of ants said in his book, Tales from the Ant World, that there ar

Please join me on this extraordinary journey, you won’t regret it. We have made it to our tenth and final episode of Aba aba. I hope you have enjoyed our journey with Gymnarchus niloticus, come on you have to admit, it is fun to say that, because I have had a blast talking about this amazing fish. The tenth thing I like about this unbelievably cool fish is conservation. As any of my longtime listeners know, I typically use the last episode to talk about the conservation status of the current animal or plant that we are discussing. This is the whole reason I started this podcast in the first place, to bring awareness to the animals and plants with whom we share this planet. We have to learn to live together if we are going to be good stewards of this amazing planet. Before we can learn to live together, we have to know what’s out there that is worth fighting for, and all the animals and plants I talk about are worth fighting for. Let’s talk about what conservation looks like for the Aba aba. When we look at the IUCN Red List, the International Union for Conservation of Nature, Gymnarchus niloticus is listed as Least Concern. This means that no conservation efforts need be taken at this time. The last time that the overall population of the Aba aba was assessed was in 2019, so this information needs some updating. The North African population was last assessed in 2007 and is also listed as Least Concern, but once again we need updated information for this population. The Western African population was last assessed in 2006 and is currently listed as Least Concern. The Eastern African population was last assessed in 2003 and is listed as Vulnerable. Vulnerable means that adult population numbers are decreasing.  Overall and in the Western and Northern populations the population trends are unknown, so the Least Concern classification may be incorrect. What’s interesting is that the Eastern population that is labeled Vulnerable also has no population trend data. What does this mean? It means we really don’t know how many aba aba are out there and if they are holding their own as our plants changes. The IUCN does list the threats to the Aba aba and those include dams, water pollution related to the military and agricultural industry, logging and wood harvesting destruction of habitat, and overfishing. Natural climate impacts are droughts. The Aba aba relies on the seasonal flooding of rivers for breeding season. The overfishing impacts the Eastern population because the local humans use Aba aba as a food source in this region. Currently there are no conservation plans being implemented in any regions of residence, with the exception of small grassroots campaign in the Eastern population region informing local fishers about the risks of overfishing the Aba aba.  Another threat to the wild population of the Aba aba in collection for the aquarium industry. Gymnarchs niloticus is a fascinating fish that many people fall in love with when they see them in a zoo or aquarium or learn about them from educational resources like this podcast.

Please join me on this extraordinary journey, you won’t regret it. We’ve reached the second to last episode of Aba aba and I find myself in a quandary. This isn’t something I like about the Aba aba but it is a topic I think we need to address, so the ninth thing I would like to talk about the Aba aba is the possibility of having it as a pet. Whenever I start a new series for this podcast, I typically know at least a little about the animal. Even if I know a lot, like about bats, I always do extra research to make sure I offer you the best and most up to date information, I can. When I picked the Aba aba, it was one of the animals I thought of first when I decided to make this podcast, I did my extra research. I have personal experience with this animal, as I have mentioned, so I knew quite a bit about its behavior, diet, and life cycle, but you can always learn more, right? As I started researching for Aba aba I did find scientific research papers but the majority of information I found about this fish came from home aquarium sites. This surprised me because this fish gets big, really big and isn’t fit for the home aquarium.  At the zoo we had a 250 gallon tank with multiple canister filters attached and our Aba aba wasn’t  anywhere near full grown. Our aquarium was only a temporary home for him while the aquatic area of the zoo was under renovation. The 250 gallons tank would not be able to host him as he got bigger.  Many of you may have had, or currently have, fish aquariums in your home. I have had some as well, both freshwater fish and saltwater fish. The largest we had was a fifty gallon saltwater tank, and I thought that was enormous for a home aquarium. So when I saw aquarium hobbyist websites talking about the Aba aba I was a little wary.  The Aba aba is a terrible choice for a pet. Beyond the large tank, and when I saw large tank I mean a 2000 gallon tank to house a full grown Aba aba, and extensive filtration set up you need to provide a clean environment for a fish of this size, you have to provide large food items, not just fish flakes for the Aba aba. Food such as silverside fish and freshwater shrimp. Aba abas are also a dangerous pet to have in your home. Their feeding behavior is intentionally brutal, as a predator you don’t want your prey to get away. Once a fish is sucked into the Aba aba’s mouth, they most likely won’t get out again. If that happens to be a human finger, you’ll be one short for the rest of your life.  I truly enjoyed taking care of our Aba aba at the zoo, and I can see what  might attract a person to this amazing animal. They are mesmerizing to watch. The constant rippling of the fin is captivating. Watching them rearrange the aquarium furniture is a delight. Offering them various enrichment items and seeing them interact with each one figuring out the puzzle of the new item is rewarding. I personally think they have cute faces, but you have to remember this is a wild animal and they are not like your typical fish you buy at the pet store. This is a predator, a problem solving predator. And you just brought it

Some we’ll find right out side our doors and some are continents away but all are fascinating.  This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it. Through the last few episodes I think I have painted a pretty good picture of the Aba aba’s anatomy and natural history. I have fascinated you with the amazing way they hunt and today, I thought we’d investigate how this fish impacts human culture. The eighth thing I like about the Aba aba is how much humans value this fish. Animals of all kinds impact other animals that reside in their habitats. Aba abas are no exception to this and they have become important in many indigenous human cultures that live where these fish are found. The first thing you may think of when speaking about how fish impact people is as food. And no doubt, we, as do many other animals, eat fish. Aba abas are highly prized as a food fish. They can grow quite large, creating a lot of meat. A five foot long fish means a bunch a meat. They are an oily fish, but several sources say they are tasty. Smoking them seems to be delightful way to eat them. In West Africa they are also eaten raw. Some cultures also gift them, alive or dead is not entirely clear, my guess is probably both. Suitors will gift them to a bride’s family symbolizing respect and goodwill. Nothing like a long, electrical fish to start off a relationship right! Certain cultures, such as the Yoruba of West Africa, will also present them to community leaders as a sign of respect during community celebrations.  The introductory paragraph of the scientific paper “Gross Anatomy and Histological Features of Gymnarchus niloticus from the River Niger at Agenebode in Edo State, Nigeria,” states: Gymnarchus niloticus commonly known as the Nile knife fish, trunk fish, or aba is one of the most valued fishes along the River Niger by the inhabitants of Agenebode and Idah. The trunk fish is highly valued for its good taste, rich nutrients, though oily flesh, ability to grow as large as 25kg, highly valued in customary rites for marriage and community celebrations. End quote. In Yoruba it is known as Eja Osan while in Hausa it is known as Dansarki which means son of a king. These names are a sign of respect for this amazing fish. (Do please forgive me if I mispronounced any words.) Since Gymnarchus niloticus is such a large fish and edible, a lot of research is going into whether it would be a good candidate for an aquaculture fish. Is raising them in a farming situation beneficial for protein production and economically sound? The answer is not yet decided but it

Please join me on this extraordinary journey, you won’t regret it. I know I left you with a cliffhanger last week and we will remedy that now! This is week seven of Aba abas and the seventh thing I like about this super cool fish is the way they hunt.  We know that Aba abas are carnivores and that they eat aquatic insects, small fish, and fresh water crustaceans. We also know that they have tiny eyes and relatively poor eyesight. There is not much discussion of olfactory functions in animals that live underwater, and I found no mention of the sense of smell when deep diving the Aba aba. Sooo…we can rule out Aba abas using sight or smell to help them find their prey. What does that leave them with for hunting? Let’s find out! Something I haven’t mentioned about Gymnarchus niloticus, yet, is that they are an electric fish. This little quirk was discovered by Hans Lissman in 1950 when he received a living specimen as a wedding gift. As he watched the Aba aba swimming in the aquarium he noticed that they could swim backwards and forwards equally well. It never ran into the sides of the tank or into anything placed inside. He wondered how it was navigating so well, thus began some of the first European studies into electroreception in fish.  Electroreception is the biological ability to detect electrical stimuli. Electrogenesis is the ability to create electrical fields. Both of these abilities are important to the Aba aba. There are two types of electrolocation. I know, there’s a lot of electric words here, bare with me. One type of electrolocation is passive. When using passive electrolocation the predator senes the electric field that the prey item creates. On the other hand, or fin shall we say, is active electrolocation. Here, the predator creates its own electric field and uses the distortions other objects create in its field to target prey or notice obstacles. Active electrolocation is practiced by three types of fish that we currently know of including Order Gymnotiformes, the knifefishes, Family Mormyridae, the elephantfishes, and our friend Gymnarchus niloticus. All of these fish are considered weakly electrical fish because they do not use their electric fields to stun their prey. Electroreception and electrogenesis are more common in aquatic animals as water conducts electricity more easily than air.  An electric fish creates an electric field with an electric organ modified from muscles in the tail. The tissue of these modified muscles are called electrocytes and they have evolved at least six times among various fish species. These organs are used for everything from prey detection to communication, mating, and even stunning prey items. The electric field created by this tissue can emanate in short bursts, as in the elephantfishes, or as a continuous wave, as with the knifefishes. To detect electric fields generated by other creatures, our Aba aba, elephantfishes and knifefishes use sense organs called Ampullae of Lorenzini. They are electroreceptors that form a network of mucus-filled pores in

Please join me on this extraordinary journey, you won’t regret it. This is episode six of Aba aba and the sixth thing I like about Gymnarchus niloticus is their diet. We have talked a bit about this is the past, but we will add a bit more detail of what Aba abas like to eat in this episode. I have a guest co-host with me this week as I have had some dental work done and need help with all this talking! My husband, Georgiy, is helping me today. Welcome Georgiy, and thanks for helping me out! Georgiy: Absolutely! Hi! Kiersten: I know you’ve been listening to this series…right? Georgiy: Riiight… Kiersten: Of course you love it. What’s your favorite thing about the Aba aba so far? Georgiy: The scientific name. Let me try to pronounce it. Gymnastic nalarcus? Kiersten: (laughs) Not even close! Gymnar-kus niloti-kus. Georgiy: (laughs) Gymnar-kus niloti-kus Kiersten: I like that too, but I like everything about the Aba aba. Can you tell our listeners what you’ve learned about what the Aba aba eats? Georgiy: I know they are carnivores, so they like to eat meat.  Kiersten: Definitely! Georgiy: When they are small, 2 to 3 inches in length, they eat insects found in the water and very small fish. A study done in Nigeria found that 36% of juvenile diets were made up of aquatic insects.  Kiersten: Really? Georgiy: Yes! 32% of the diet was made up of fish. Kiersten: Interesting. Did it say what kind of insects and fish? Georgiy: No. They looked at stomach contents of dead juveniles, so they only found small parts of the digested prey. Kiersten: Hmmm. It sounds like the juvenile Aba aba is a specialist feeder on insects? Georgiy: Yes! Exactly. Another study showed that Aba aba young that have used up their egg yolks will eat the midge larvae that are in the nests with them! The adult midges lay eggs on the grasses that the male Aba abas use to make their nests! Kiersten: Wow! That’s so smart. I love it! Bring the food to you. Does their diet change as they get older? Georgiy: Yes. As they get older, and larger, they can eat bigger prey items. They will eat more fish, such as silversides, tetras, or African catfish, and add crustaceans to their diet. They will still eat insects but this makes up very little of the diet when they are adults. Kiersten: That sounds like a smart survival plan. Georgiy: Yes. The Aba aba are not competing with each other for food sources and they don’t risk injury by hunting something larger than themselves. What did you feed them at the zoo? Kiersten: Ooo. Good question! We fed them silver side fi

Please join me on this extraordinary journey, you won’t regret it. I can’t believe we are half way through Aba aba already, but here we are at episode five. The fifth thing I like about Gymnarchus niloticus is their anatomy. Up until now, we’ve talked about some of the very interesting parts of the Aba aba’s body, but in this episode we’re going to talk about the Aba aba’s anatomy as a whole.  If we start from the inside out, we already know that the Aba aba has a bony skeleton as it is classified as a ray-finned fish which has an internal bony skeleton. That is going to include a skull, elongated with small sharp teeth in the lower jaw and a bony tongue. Last week we discovered that bony-tongues fish have teeth in their tongues, but Gymnarchus niloticus is an exception to this. Instead of having teeth in the tongue they have teeth in both the lower and upper jaws. Their bony tongue is used to hold prey still for easier swallowing. The teeth, though sharp, are not triangular, but peg-shaped. They look like a flat-head screwdriver bit that fits into a power drill. The lower mandible is rounded and is deeper than the upper. The upper jaw does have teeth, as well. The upper jaws teeth are also peg-shaped. The bottom jaw teeth number around 24 teeth while the upper jaw has only 10 to 12. There is only one row of teeth on both jaws. The structure of the jaw gives the Aba aba a perpetual smirk. Let me inject a funny story here as it pertains to the teeth of this amazing fish. As you know, listeners, I worked with an Aba aba at the zoo and one day, I was cleaning the algae off the glass of his tank. This was a precarious job and typically entailed two people, one to clean the glass and one to watch where he was in the tank. Well, this day we were all busy but the algae on the glass had become a bit more unsightly than we liked so I said I would clean it alone. That was the day I got bit by an Aba aba.  It was a bit more startling than terrifying, I must say, as he caught me off guard hiding in the plastic plant nest he’d built in the center of the tank. I thought I knew where he was but he got my upper arm as is it slipped below the water line just next to the nest. A scary sucking sound ending with a pop and a sting told me I’d just been bitten. He tagged me on the underside of my upper arm just below my armpit. It didn’t hurt much, or bleed that much either, it felt more like a scrapped knee, but the bite was wicked cool. It looked like a dotted circle and I hoped it would scare, because that would have been one heck of a scar to talk about later, but it healed up perfectly fine with nothing left to show for the exciting moment.  I had a hard time finding research that described

Please join me on this extraordinary journey, you won’t regret it. In episode four, we're going to jump back a bit to episode one and delve into more detail about about the class, order, and family of the Aba aba. The fourth thing I like about Aba abas is their classification. In episode one I briefly described the classification of this fish, but I think we should investigate the class, order, and family of Aba abas a bit more closely. First for my first time listeners, or for those who are not students of biology, what is classification?  It a system that scientists and researchers use to connect all living things but to also individualize all living things. Whether flora (plants) or fauna (animals) we are all related through physical characteristics.  Way back in the day, like way back in the 1700s, Carl Linnaeus was a Swedish biologist and physician who developed a binomial nomenclature (a two part name) to organize every living thing into groups. It helped man understand the natural world around him. We still use this classification system today, even though the attributes we use to organize individual plants and animals into their groups has evolved over the years. In the beginning, naturalist used things like appearance and behavior to place animals and plants into the same groups, but now we look at genetic similarities to classify living things. The two part name consists of the genus and the species. This helps make sure that when you are talking about an individual animal or plant with another researcher you are talking about the same plant or animal. Animals often have different common names around the world and even have different names within the same country. For example, fireflies are known as fireflies, lightening bugs, and glow-worms. These common names vary depending on what region of the United States you may be visiting, but we’re all talking about the same insect. The Aba aba is known as Aba aba, African knife fish, Frankish, freshwater rat-tail, or aba fish, so researchers refer to it as Gymnarchus niloticus.  If we take a few steps back in the classification we can learn even more about an animal. So let’s do that now with Gymnarchus niloticus. When we look at the Class level of this animal, Actinopterygii, we know that it is a ray-finned fish. What exactly does that tell us? Well, Actinopterygii are fish that possess fins that are made of webs of skin supported by bony or horny spines. We also know that fish in this Class usually have complex skeletons of true bone. Ray-finned fish are the dominant aquatic vertebrates in the water today. They make up about half of all vertebrate species known and are found in every aquatic habitat from the deepest depths of the ocean to freshwater streams and ponds.  So this level of classification lets us know that Aba abas have a bony skeleton and some sort of webbed fin on their body. It’s a great start. The next step is the Order. This will narrow down things ever more. Aba abas are classified in Order O

Please join me on this extraordinary journey, you won’t regret it. Episode three of Aba aba is here and we are talking about reproduction. The end of episode two hinted at reproduction kicking off with the rainy season so that’s where we’ll begin. Join me for the third thing I like about Aba abas, reproduction. It all begins when two Aba aba love each other, no really, it all begins with the rainy season. In the continent of Africa many animals rely on the abundance of the rainy season. This season brings rain that is a necessary resource for survival of all living things, as well as flooding the rivers. Flooded rivers overflow into flood plains where food becomes abundant. Terrestrial invertebrates are often caught off guard and drown leaving them to be consumed by aquatic carnivores, like the Aba aba. The Aba aba already lives in the water but when those waters rise nutrients increase and aquatic vegetation gets thicker. Then it’s time to start looking for a mate. In studies performed in the Lower River Niger, two breeding peaks were observed. One from May to July, the other from October to January. The breeding behavior of Gymnarchus niloticus is heavily dependent on the flooding of the rivers. Beyond the food resources that increase at this time the aquatic plants that increase are important for the nest making of the Aba aba. Now, the males of the species are the ones that make the nests. This is not uncommon in fish na the Aba aba is no exception. Their nests can be pretty big, but that is not a surprise for a fish that can get 5 feet in length. The male Aba aba makes a nest with uprooted aquatic plants. He pulls up the plants himself and weaves them into a floating nest that can be 1 meter, or 39 inches, in width. The perimeter of the nest is molded with the mud from the roots of the plants. It is expertly woven. It will be anchored to other plants and have an opening through which the male can enter and depart when needed. A little bit of the top of the nest will stick out of the surface of the water. If the nest becomes dislodged the male will remain with it as it floats down the river. Inside the plants the male will create a bubble nest. This portion of the nest is made of air bubbles and this is where the eggs will be nestled. The nest is important for several reasons: The first is to attract a mate. The ladies are attracted by large, well made nests, so the gentlemen will take their time picking the right plants for just the right nest. A few studies have indicated that they prefer plants in Family Poaceae, which are the grasses. The oblong leaves of the grass are perfect for weaving. We have to remember that this animal is wea

Please join me on this extraordinary journey, you won’t regret it. This is the second episode of Aba aba, or Gymnarchus niloticus, and the second thing I like about this little known fish is where they are found. Let’s talk about where in the wild this fish is naturally found and what kind of habitat they tend to like best. This episode may be a bit shorter than most, but I promise to make up for it in future episode of this series. In episode one we found out that the Aba Aba is found in Africa. They can inhabit bodies of fresh water in the Nile, Turkana, Chad, Niger, Volta, Senegal, and Gambia basins. It is wide spread throughout West African countries of Egypt, Benin, Burkina Faso, Central African Republic, Chad, Cote d’Ivoire, Ethiopia, Ghana, Kenya, Mali, Mauritania, Niger, Nigeria, Senegal, South Sudan, Sudan, Uganda, and Gambia. It has been reported in Cameroon, where it is an introduced species, but identification here still needs further confirmation. By widespread I mean that they can be found in various bodies of freshwater such as lakes and rivers in these areas but they are sparsely spread.  These fish need fairly large territories, remember that can get up to five feet in length and weigh 42 pounds, and spend most of their lives as solitary individuals, so therefore, they are sparsely spread throughout their natural habitat. Now that we know where in the world to find these amazing fish, what kind of habitat are we looking for? We know they like freshwater and can be found in lakes and rivers. They will most often be found in areas with dense aquatic vegetation. They use this to hide from larger predators and to help camouflage themselves from prey items.  In rivers, they favor the edges of the water near the banks to keep out of the rushing currents toward the middle. Don’t get me wrong, they can swim well, but the edges host the plants they need to rest in during the day. Aba aba are nocturnal, so they are most active at night and they spend their days resting in the vegetation. They can use the plants a bit like a hammock, supporting them while they sleep. Aba aba fish have very small eyes and are a bit sensitive to light so this is another reason to live in and around thick vegetation.  Their behavior is seasonally influenced by the rains of this continent, as are many species of animals that live on the African continent. When the rains come breeding season begins, but you’ll have to wait for the next episode to find out the unique breeding behaviors of the Aba aba. That’s it for the second episode of the Aba aba. Thank you for joining me to find out where this amazing fish lives because it is my second favorite thing about them.  If you're enjoying this podcast please recommend me to friends and family and take a moment to give me a rating on whatever platform your listening.

I was a zookeeper for many years and have worked with all sorts of animals from Aba Aba fish to tigers to ravens to domesticated dogs and so many more in between. Many of those years were spent in education programs and the most important lesson I learned was that the more information someone has about a particular animal the less they fear them.

Okay, I had to throw in a reference to Jaws, being that it’s fifty years old this year, and also one of the reasons that an entire generation of people fear sharks. But that is another series all together.  This episode is the first in a new series about a fish. The Aba aba fish to be specific. Never heard of it? That’s exactly why I picked it as my next unknown creature. This first thing I like about the Aba aba fish, is the Aba aka fish. We will start off this series with an overview of this wicked cool fish to whet your appetite to learn more. The Aba aba fish, Gymnarchus niloticus, is also known as the African knife fish, Frankish, freshwater rat-tail, or aba fish. It is a long, slender bodied fish with only one fin. The dorsal fin runs from the back of the head to the tip of the tail on the top-side of the body. This is their only fin and the reason they are called knife fish because they kinda look like a knife if you used the head as the handle.  Aba aba are typically black to gray to brown on the top half of the body while the underside is a paler color, such as white or beige. They are covered in very small scales that do not stand out making it look like they have smooth skin. Adults can reach a length of five feet or 1.6 meters and weight 42 pounds or 19 kilograms. That’s a pretty big freshwater fish. Classification of the Aba aba is as follows- Kingdom: Animalia Phylum: Chordata Class: Actinopterygii (the ray-finned fish. These are fish that have lightly built fins made of webbings of skin supported by thin bony spines) Order: Osteoglossiformes (this is an order of ray-finned fish known as the bony tongue fish and we will delve into to this in more detail in a future episode) Family: Gymnarchidae  Genus: Gymnarchus (meaning naked bum) Species: niloticus (meaning from the River Nile)     They are the only fish in the family Gymnarchidae and in the Genus Gymnarchus which makes them special.  In the wild the Aba aba is found in the freshwaters of Africa. They live n the lakes an

Please join me on this extraordinary journey, you won’t regret it. This is the final episode of Screamers and we’ll be talking about conservation. Like everything else with Screamers this episode will have a few twists. The tenth thing I like about Screamers is conservation. Each species has a story of it’s own, so we’ll take them one by one. Let’s start off with the Southern Screamer. Southern Screamer, Chauna torquata, also known as the Crested Screamer is found from the eastern half of Bolivia south into Argentina as far as Buenos Ares Province and east through Paraguay into south western Brazil and Uruguay. The conservation status of the Southern Screamer is listed by the International Union for Conservation of Nature and Natural Resources as Least Concern. This means that Southern Screamer population numbers are steady or increasing. Their population trend is listed as stable with adult individuals estimated between 66,700 to 667,000 individuals. The last time this species was assessed was in 2024. This species of Screamer is impacted by habitat loss. As wild lands are drained and deforested to create more land for cattle ranching and farming, Southern Screamers lose vital habitat, but a 27,000 acre reserve created in 2008 by Asociacion Armonia to protect the Blue-throated Macaw had the added bonus of offering protected habitat to the Southern Screamer. Barba Azul Nature Reserve protects 250 species of birds and is an important stop over for migratory shorebirds.  If you are interested in seeing the Southern Screamer at the reserve you can book a conservation birding trip through American Bird Conservancy. All fees support the reserve and American Bird Conservancy’s mission for protecting wild spaces for birds. Now there are other things keeping the Southern Screamer protected, this is the twist for this species, ranchers and farmers actually like having Southern Screamer nearby as they are excellent guard birds and raise the alarm when any predators come near. Sometimes people sneak a young Screamer away from the parents and keep them on their property for exactly that reason.  Southern Screamers have also been seen eating invasive plants species, such as white clover, which means they are helping their own conservation efforts.  The Northern Screamer, Chauna chavaria, also known as the Black-necked Screamer is in a similar situation as the Southern Screamer. This Screamer is found across northern Columbia from the Atrato River and Magdalena River valleys east into the Lake Maracaibo area of Venezuela. They are also under pressure from habitat destruction for ranching and agricultural use. As of the latest surveys in 2023, the Northern Screamer is listed as Least Concern by the IUCN. Their population is stable with 60,000 to 130,000 mature adults. Locally, in Columbia and Venezuela, they are listed as Vulnerable. Conservation efforts in these countries include educational campaigns bringing awareness to Northern Screamers

Some we’ll find right out side our doors and some are continents away but all are fascinating.  This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it. This is the penultimate episode of Screamer and the ninth thing I like about this animal is their eyes and beaks. One of the things that is often overlooked in bird is their eye color, so today we will delve into the variations that exist by looking through the eye of the Screamer. Bird beaks, or bills either is correct, also vary extensively through out the avian family. Beak shape often indicates what type of food the birds eats, but like everything else about the Screamer, things are not always as they seem. Bird eye color varies more than anyone expected. Not many researchers have attempted studying this characteristic and the few that have taken up this research topic and finding more questions than answers. Colors ranged form dark black or brown to vivd emerald green, sapphire blue, scarlet and crimson, turquoise, and even white. There is even a bird with pink eyes. It is absolutely amazing the various hues that birds’ eyes contain.  Irises can be one color or more than one. The eyes of Rock Pigeons, one of the most disliked birds around the world, are bicolored starting with a ring of yellow on the outside and red/orange close to the pupil. The Satin Bowerbird has eyes with a vibrant blue ring on the edge of eye with an equally vibrant ring of purple next to the pupil. The Three-streaked Tcharga has a ring of light spots that look like stars set in a dark background giving them some of the most unique bird eyes around.  Eye color in birds can change as a bird matures, for example Osprey eye color changes from red as juveniles to yellow as adults. Sexual dimorphism is also present in some species of birds meaning the female’s eyes are a different color than the male’s. Seasonal changes in eye color can also happen, for example Brown Pelican eyes change from brown to blue during breeding season. Southern Screamers and Northern Screamers both have brown eyes as adults, while Horned Screamers can have yellow to orange to red eyes as adults. To clarify, I found no research indicating that these birds eye color changes as they age, but I could only find reference to their adult eye color.  There are three things that contribute to the color of a bird’s eye, pigments, blood vessels, and structures. These three color options are still being closely studied but certain pigments are responsible for light colors and different pigments are responsible for darker colors. For example, carotenoids are responsible for the orange color of birds in Family Anatidae which includes certain ducks. An increased amount of blood vessels in the eye creates the red eyes of some species.  Why do bird have such varied eye color? The short answer is we just don’
