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.

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]

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.[citation needed]

Habitat[edit]

Casquehead lizards are forest-dwelling.

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]
