Okay, quick pop quiz. Both of these creatures (see to the right) are called toads, but one of them's a reptile, and the other's an amphibian. Any guesses? The one on the right is just a toad. Now, you wouldn't think you'd find an amphibian in the desert, but these guys are really, really smart. They only come out when it's rainy or wet. When it's hot like this, they'll burrow under the ground.
