Animals have a lot in common with people: they eat, sleep, and have babies. That's sometimes where the similarities end! Rabbits, for example, eat their own poop so they can digest even more nutrients than they did the first time around. Readers might find this and other facts gross, but they'll also love to repeat them! Full-color photographs and diagrams complement a fun design full of surprising and interesting information about animal bodies and behavior. Informal language draws readers into science concepts covering simple biology and environmental adaptation.
