Basiliscus (lizard)

Taxonomy and etymology

Both the generic name, Basiliscus, and the common name, "basilisk", derive from the Greek basilískos (βασιλίσκος) meaning "little king". The specific epithet, vittatus, which is Latin for "striped", was given in Carl Linnæus' 10th edition of Systema Naturæ.

Description

Basilisks on average measure 70 to in total length (including tail). Their growth is perpetual, fast when they are young and nonlinear for mature basilisks. Their skin is shed in pieces.

Basilisks are oviparous and lay 8–18 eggs.

Running on water

Basilisks sometimes run bipedally. Basilisks have the ability to run on water for short distances, and because of this, they have been dubbed the "Jesus Christ lizard" in reference to the biblical passage of Jesus walking on water. On water, basilisks can run at a velocity of 1.5 m per second for approximately 4.5 m before sinking on all fours and swimming. Flaps between their toes help support basilisks, creating a larger surface and pockets of air, giving them the ability to run across water.

Sailfin lizards and a few species of anole lizards can also run on water.

Other defense mechanisms

Basilisks can burrow into sand to hide from predators; a ring of muscles around both nostrils prevents sand from entering the nose.

Habitat and geographic range

Basilisks are abundant in the tropical rain forests of Central and South America, from southern Mexico to Ecuador and Venezuela.

Invasive species

The species Basiliscus vittatus (brown basilisk) has been introduced to Florida. It has adapted to the colder winters by burrowing into leaf litter for warmth. Current reports sight the brown basilisk as far north as Fort Pierce, on the state's East Coast, where small groups have crept up the North Fork of the Saint Lucie River. Mainly it has been seen in Boca Raton and other cities in Palm Beach County. as seen in this photo taken in West Palm Beach, Florida.

Classification

Genus Basiliscus has four extant species:
