Basiliscus mitratus  [now Basiliscus vittatus] - Brown Basilisk
Named after the mythical creature that could turn one to stone with its gaze, basilisk lizards are mid-sized, speedy, and to early explorers, appeared almost supernatural. One of their primary modes of escaping predators is their speed - and that speed (combined with long toes that have air-trapping flaps on the side) lets them easily run across water for up to 20 meters as juveniles, and 5-10 meters as adults. Their “sails” are used to absorb sunlight for warmth, and disperse heat during hotter days. Two species (the Brown Basilisk and Common Basilisk) have fat-filled “head cones”, shown to sustain them during dry seasons (much the same as camels). It’s unknown why some species, such as the Red-Headed Basilisk, do not have the same sort of cone, when they live in similar environments.

info via Bibliotheca Alexandrina

A robustly built lizard, which reaches large size, up to 140 mm SVL. Back and dorsal surface of tail covered with regular bands of low and smooth tubercles. Tubercles without clear rosettes of medium-sized scales. Tubercles are separated laterally from each other by 6-7 small scales. There is an average of 27 lamellae under the fifth toe. Temporal region covered with large tubercles widely separated by small scales. Postmentals smaller than the gulars. Rostral enters nostril. General color of dorsum ranges between dark brown-gray to light sandy-gray. Back with 4-5 dark and light crossbars and there are usually 4 distinctive white spots with dark borders on the scapular region. Tail with light and dark bands. Venter off-white.

Male larger than female, with broader head. General color of dorsum varies according to the dominant color of the habitat and environmental factors, such as temperature. The scapular spots are usually not easily discernible on juvenile animals and become well developed in adults.
