Brown basilisks are known as the "Jesus Lizard" because if their ability to walk on water to run on water. They aren't native to Florida but come from Mexico, Central America and the northern portion of Colombia. The largest concentration of brown basilisks in Florida is in Miami-Dade and Broward counties.
They are not considered invasive since the FWC isn't sure if brown basilisks pose to native species, although it is believed to eat small vertebrates, including native lizards, as part of its diet.
Males, as shown here, have a large crest on the back of their heads and a serrated crest that runs along their backs from the neck to the hind legs. Females are smaller and lack the crest.
