Running on water

Smaller brown basilisks can run about on the water without sinking. Young brown basilisks can usually run further than older ones. If the animal faces danger, it starts to run very fast on the surface of a river or a lake. The flaps on its hind feet are then opened and thus more surface area is provided for it to run on water.

. Like most reptiles, the brown basilisk is active during the day. Its outstanding camouflage allows it to remain motionless and very hard to detect. The maximum lifespan of the brown basilisk is probably around 7–8 years. In the wild, most die much sooner.

Reproduction

Female brown basilisks lay about 2–18 eggs, five to eight times a year. Eggs hatch after about three months and the babies weigh around . It is hypothesized that they reproduce year-round, but males exhibit a peak in spermatogenic activity during the dry season and a peak in insemination and/or copulation at the beginning of the rainy season.
