Corytophanidae is a family of iguanian lizards, also called casquehead lizards or helmeted lizards,[4] endemic to the New World. Nine species of casquehead lizards from three genera are recognized.
Geographic range[edit]
Corytophanids are found from Mexico, through Central America, and as far south as Ecuador.
Certain species are now extant in South Florida and are considered invasive.
Description[edit]
The casquehead lizards are moderately sized lizards, with laterally compressed bodies, and typically have well-developed head crests in the shape of a casque helmet. This crest is a sexually dimorphic characteristic in males of Basiliscus, but is present in both sexes of Corytophanes and Laemanctus.[5] In past years there has been evidence of corytophanids in the Eocene of North America. The greatest percentage of omnivorous species (> 10% plant diet), over 30% in each, and the highest mean percentage of plant matter in the diet are corytophanids.[6]
Behavior[edit]
In Corytophanes, the head crests are used in defensive displays, where the lateral aspect of the body is brought about to face a potential predator in an effort to look bigger.[5] Unlike many of their close relatives, they are unable to break off their tails when captured, probably because the tail is essential as a counterbalance during rapid movement.[7]
Habitat[edit]
Casquehead lizards are forest-dwelling. All corytophanids are excellent climbers, and they are usually found in trees or low bushes.
Reproduction[edit]
Despite the small number of species in the family Corytophanidae, it includes both egg-laying species and species that give birth to live young.[4]
