Corytophanidae

provided by wikipedia EN

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

Corytophanids are found from Mexico, through Central America, and as far south as Ecuador.

Certain species are now extant in South Florida which are considered invasive.

Description

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

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.

Habitat

Casquehead lizards are forest-dwelling.

Reproduction

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]

Nota bene: A binomial authority in parentheses indicates that the species was originally described in a different genus.
