The smooth helmeted iguana (Corytophanes cristatus), also known as the helmeted iguana, the helmeted basilisk, the elegant helmeted lizard, and several other common names, is a species of Basilisk and a New World lizard in the family Corytophanidae. The species is native to southern Mexico, Central America, and northwestern South America.
The smooth helmeted iguana is named for the prominent casque, or crest on the back of its head and neck which has the appearance of a helmet. The Corytophanidae family of lizards is thought to have Euramerican and Laurasian ancestral beginnings, and is believed to have moved down to the tropics after the Eocene period cooling, approximately 33–56 million years ago.
C. cristatus can be found ranging from Chiapas in southern Mexico to north-western Colombia. The habitat it primarily occupies in this range is primary and secondary mesic rain-forest. It lives predominantly in trees, but also hunts on the forest floor where it uses leaf litter as a micro-habitat.

GBIF citizen-science records
It is estimated from how often the Helmeted Iguana is recorded against all the reptiles logged in Tortuguero National Park (29 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
