Brown basilisk
The Brown basilisk (Basiliscus vittatus), also known as the striped basilisk, is a lizard species native to Mexico, Central America, and northwestern Colombia, with introduced populations in Florida. It is distinguished by its ability to run across water for short distances, a feat enabled by specialized flaps on its hind feet. Males are generally larger than females and possess a more prominent dorsal crest.

About Brown basilisk
The Brown basilisk, scientifically known as Basiliscus vittatus, is a striking lizard species renowned for its remarkable ability to run across the surface of water. Native to the tropical regions of Mexico, Central America, and parts of northwestern Colombia, this species has also established introduced populations, notably in Florida.
Description and Adaptations
Adult Brown basilisks exhibit sexual dimorphism; males are generally larger than females, with the former reaching up to 61 centimeters (24 inches) in total length, including their tails. Both sexes possess a distinctive three-part dorsal crest that runs along the head, back, and tail, though it is more pronounced in males. Their coloration typically ranges from brown to olive brown, marked with black crossbands that often appear on the flanks and the dorsal crest. A characteristic white stripe extends from the eyes to the hind legs.
The Brown basilisk's most famous adaptation is its capacity to run on water. This is facilitated by specialized flaps of skin on the edges of their toes, which increase the surface area of their hind feet. When propelling themselves rapidly across the water's surface, these flaps help them stay afloat for short distances, allowing them to escape predators or traverse aquatic obstacles.
Behavior and Reproduction
Brown basilisks are diurnal, meaning they are active during the day. They are adept at camouflage, often remaining motionless to evade detection by predators. Their diet primarily consists of insects and other small animals.
Reproductively, female Brown basilisks are prolific egg-layers, producing clutches of 2 to 18 eggs, anywhere from five to eight times per year. The incubation period for these eggs is approximately three months, after which hatchlings emerge weighing around 2 grams. While reproduction may occur year-round, there is evidence suggesting peaks in male reproductive activity correlating with seasonal changes.
Taxonomy and Etymology
The generic name Basiliscus is derived from the Greek word basilískos, meaning "little king." This name references the mythical basilisk of Greek legend, a creature said to possess deadly powers. The species was first described by Carl Linnaeus in his seminal work, Systema Naturae.

What is the brown basilisk's most distinctive ability?
The brown basilisk is most famous for its ability to run across the surface of water for distances of 10 to 20 meters. This allows it to escape predators by appearing to 'walk on water'.
How large do brown basilisks get?
Male brown basilisks can reach a total length of up to 61 centimeters (24 inches), including their tail. Females are typically somewhat smaller than males.
What is the coloration and appearance of the brown basilisk?
Brown basilisks are typically brown or olive brown with black crossbands, which are often found on the flanks and dorsal crest. A distinctive white stripe runs from their eyes to their rear legs.
What is the typical lifespan of a brown basilisk?
The maximum lifespan for a brown basilisk is estimated to be around 7 to 8 years. However, many individuals in the wild likely do not survive this long.
How do brown basilisks reproduce?
Female brown basilisks lay between 2 and 18 eggs, up to five to eight times annually. The eggs typically hatch after about three months.
Are brown basilisks active at night?
No, the brown basilisk is active during the day. They are diurnal reptiles and rely on camouflage to remain undetected.
