What do spiders, bats, ducks, and sloths have in common?

Along with many other creatures, they turn upside down. A few of them, in fact, spend most of their lives this way. But animals don't go bottoms-up just for fun.

In this unique pop-up book, pull tabs, lift-the-flaps, sliding doors, and other interactive elements reveal how, for many animals, an occasional flip or dip is a matter of survival.
