Teiids of the United States
Teiids are long slender lizards with long whilike tails and well developed legs. Movements are characteristically rapid and jerky. They range from 4" to 48" in length. Typically they have small round, non-overlapping scales on the back and large rectangular scales on the belly. There are no bony plates (osteoderms) in the skin. The large regular head shields are fused to the skull.
Whiptails ar diurnal, terrestrial carnivores. Small species feed on incests and other invertebrates, while larger species consume small mammals, birds, bird eggs, and other reptiles. Prey is located both by sight and by small or taste, by means of a long protusible deeply forked tongue.
All teiids are egg layers. In most species, females produce fertile eggs only after breeding with males of the same species. However, tehre are true unisexual species among Cnemidophorus. All individulas are females, so there is no mating. A mature female lays fertile, but unfertilized, eggs taht hatch into more females
