Book excerpt: They’re SSSSLITHERY! SLIPPERY! They creep us out! But get to know them and you’ll find snakes private, quiet types who just want a cool, shady place to call home. From the tip of their forked tongues, to skin that sheds, to the rattles on certain tails, these creatures have secrets all kids will love. Cool photos and fun facts slip us inside their surprising world. National Geographic supports K-12 educators with ELA Common Core Resources. Visit www.natgeoed.org/commoncore for more information.
