The iguanoids, which comprise about three hundred species, arranged in fifty genera, may be regarded as especially characteristic of South and Central America, although they extend into the warmer parts of the northern half of that continent, ranging in the west as far as British Columbia, and in the east to Arkansas and the Souther United States, while they are also represented in many of the American islands.

While many of the teiids and varanids are active foragers, many of the iguanoids are clearly sit-and-wait predators.

Via interactions between the external environment and their nervous and hormonal systems, many iguanoids have the novel ability to change their body color.
