Iguanids of the United States
Iguanids range from 4" to 72" in length. A typical iguanid is of moderate size, has 5 clawed toes on each of four legs, and a long tail. Its teeth are attached to a ledge on the inside of the jaw. Most species are either arboreal or terrestrial and feed on insects and other invertbrates, but some, like Dipsosaurus and Sauromalus eat leaves, fruit, and blossoms. Except for a very few species that live in cool mountina habitiats and give birth to living young, iguanids are egg-layers. Clutches of many eggs or offspring are the rule, but Anolis lays one one egg every couple of weeks.
Iguanids are possibly the most visually orientated of all lizards. They communicate at a distance by a show of color and behavioral signals. Mates are courted, territories defended, and interlopers driven off by elaborate and precisely timed combinations of head-bobbing, body push-ups, and open mouth displays that are unique to each species. Some further enhance the effect bu curling the tail, inflating the chest and throat, or extending the throatfan, all of which expose a bright patch of color to the view of another lizard. Some species exhibit intense color during mating season.
