Poop

"Playful, but filled with information, this book takes poop out of the sewers and into the scientific community where it belongs." --The Horn Book

Hippos navigate by it, sloths keep in touch through it, dung beetles eat it . . . and most grown-ups would rather not mention it. But scientists who study animal feces find out all sorts of things, such as the number of insects a bat eats or just how a T. rex devoured a triceratops 70 million years ago. Poop is an excellent prototype for recycling and perhaps the most useful stuff on Earth. Take a peek at Poop and find out what it's for, where it goes, and how much we can learn from it.
Back matter includes an index and a glossary.
