About the Brown Basilisk

The brown basilisk (Basiliscus vittatus), also commonly referred to as the striped basilisk, is a species of basilisk lizard in the family Corytophanidae. The species is native to Mexico, Central America and adjacent northwestern Colombia, and has been introduced into the U.S. state of Florida as an invasive species. The brown basilisk has large hind feet with narrow flaps of skin on the distal edge of each toe. The fact that it moves quickly across water gives it the appearance of "walking on water".

The male brown basilisk can reach 61 centimetres (24 in) in total length (including tail), but the female is somewhat smaller. It has a three-part dorsal crest on the head, along the back, and along the tail. Coloration is brown or olive brown with black crossbands. The crossbands are usually only on the flanks and on the dorsal crest. There is also a white stripe, which extends from the eyes to the rear legs. The male has a larger crest than the female. The brown basilisk weighs 200–600 g (0.44–1.32 lb). It has long toes with sharp claws.

The brown basilisk's generic name Basiliscus is taken from the creature of Greek mythology made up of... Wikipedia →
