(Piano music stops)   Kiersten - Welcome to Ten Things I Like About… I’m Kiersten, your host, and this is a podcast about misunderstood or unknown creatures in nature. 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 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!
