Basiliscus vittatus, the Brown basilisk;
Miami-Dade county, Florida (11 June 2016).
Check out that fantastic crest! This is a good-sized Brown basilisk, a non-native species now well-established throughout portions of the Florida peninsula, photographed in Miami-Dade county. This is a fairly speedy species, and younger Brown basilisks can actually run a distance on the surface of water. Still, even the larger ones can catch some serious velocity on open ground. This is not the easiest lizard species to catch up to — by land or by water.
