Lizards are cool. Literally. They are ectotherms, which means they can't make their own heat. That's why you see many types of lizards basking in the sun, seemingly doing nothing at all. That's the life. But make no mistake, lizards have very busy lives-looking for food and avoiding being food. Popular science writer Sneed B. Collard III gets down and dirty with all kinds of lizards-from your average "Joe Lizard," the western fence lizard, to the impressively large Komodo dragon. In a kid-friendly narrative, Sneed explores many different kinds of lizards, their habitats, defense systems, hunting techniques, and mating rituals. He reveals the exciting life of a lizard-from rappelling from the tops of trees to the forest floor, to dropping off a tail to get away from a predator.
