Anolis sagrei
a lizard native to Cuba and the Bahamas. It has been widely introduced elsewhere, and is now found in Florida and as far north as southern Georgia, Texas, Taiwan, Hawaii, Southern California, and other Caribbean islands.
This species is highly invasive.[1] In its introduced range it reaches exceptionally high population densities, is capable of expanding its range at an exponential rate, and both out competes and consumes many species of native lizards.[2][3][4] Its introduction in the United States has altered the behavior and triggered a negative effect on populations of the native Carolina Anole (Anolis carolinensis)
As a defense mechanism, Brown Anoles can detach most of their tails when pursued or captured. The piece that breaks off will continue to move, hopefully distracting the predator allowing the anole to escape. The lost tail will partially regrow.[6] If provoked, the Brown Anole will bite, urinate, and defecate. Predators include rats, snakes, birds and any predator that is larger than they are. Recent work in experimentally introduced populations in the Bahamas has shown that body size in the Brown Anole may not be affected by predation, as was previously thought to be the case
