Poop

<b>"Playful, but filled with information, this book takes poop out of the sewers and into the scientific community where it belongs." —<i>The Horn Book</i><br></b><br>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 <i>Poop</i> and find out what it’s for, where it goes, and how much we can learn from it.<br>Back matter includes an index and a glossary.
