Do spiders have ears? Do rabbits fart? What is the toughest animal in the world? Can animals talk and what do they say? What is the point of a flightless bird? Animals are brilliant, aren't they? Even though we think of ourselves as the cleverest and best creatures on the planet, there are still plenty of things other species can do that we can't. Among them there are those that can move faster, dive deeper and see and hear further than we could ever hope to do. Some can even change colour, and others can paralyse us with deadly poisons. But why do some of them seem so badly adapted? If dolphins are so clever, why haven't they learned to breathe underwater? If dinosaurs were so terrifying, why aren't there any left? And what is the point of a flightless bird? Explore all the real mysteries of the animal kingdom and find out the answers to these and an awful lot of other brilliant questions about animals in this funny and informative book from the Why is Snot Green? series, published in association with the Science Museum.
