About the Common Basilisk
The common basilisk (Basiliscus basiliscus) is a species of lizard in the family Corytophanidae. The species is endemic to Central America and South America, where it is found near rivers and streams in rainforests. It is also known as the Jesus Christ lizard, Jesus lizard, South American Jesus lizard, or lagarto de Jesus Cristo for its ability to run on the surface of water.
The common basilisk can be distinguished from similar species within its range by its large size and the high fin-like crest along its back. Most common basilisks are brown and cream in color. Males also have high crests on the head and tail. Both genders are brown to olive, and have a white, cream, or yellow stripe on the upper lip and a second stripe along either side of the body; these stripes have higher contrast in juveniles and fade as the lizards age.
Hatchlings weigh a mere 2 grams (0.071 oz) and are 38 to 43 mm (1.5 to 1.7 in) long. Adults can grow to a total length (including tail) of 76 cm (2.5 feet). Females are generally 135 to 194 g (4.8 to 6.8 oz), and weigh half as much as males. The tail comprises 70 to 75% of the total length: for example, a 70-cm-long (27.5-inch-long) common... Wikipedia →
