There is a saying that someone is "eagle-eyed" if they spot minute details - and if I asked you to name an animal with good eyesight, you'd probably think of an owl or an eagle. But in this episode we'll hear that the largest relative eye size of any vertebrate is found in an entirely different group of animals - frogs and toads. Kate Thomas, who is a postdoctoral researcher at the Natural History Museum in London, surveyed eye size in hundreds of frogs and toads and asked how eye size has evolved in this diverse group. Why do frogs and toads have such large eyes? How does eye size affect vision in the first place? And did you know that many frogs can see colors in the dark?
