Lizards display so much diversity that it is almost hard to believe one name applies to them all. Many lizards, such as the Little Brown Skinks in the U.S. and the Pygmy Chameleons of the African forests, are so tiny that they make a blade of grass look huge in comparison. In other areas, lizards are large apex predators—Komodo Dragons even hunt water buffalo! Lizards live in trees, on the ground, under rocks, in the soil, and everywhere in between. They can be diurnal (daytime active), nocturnal (nighttime) or crepuscular (active at dawn or dusk), and some alternate throughout the year. Some have four legs, and some have two or none. Some have smooth, glossy scales; others bristle with spikes.
