What shape is wombat poo and why?Why might a crab turn into a zombie?What does a tree-shrew use as a toilet?And which creature WANTS to be eaten? Food is what keeps every animal alive, including us. But eating is not as simple as it seems. Bodies need to break down the food they eat, and this is where the digestive system plays a starring role. A starfish, a giraffe, a vulture and a bee eat, digest and poo in very different ways, and there's always a reason why. This fabulously illustrated book opens up the digestive systems of a dizzying range of vertebrates and invertebrates, and explains why, in the animal kingdom, you really are what you eat!
