The brown anole

Description:

The brown anole (Anolis sagrei) is a lizard native to Cuba and the Bahamas. It has been widely introduced elsewhere, by being sold as a pet lizard, and is now found in Florida and as far north as southern Georgia, Texas, Taiwan, Hawaii, Southern California,[1] and other Caribbean islands. This species is highly invasive.[2] In its introduced range, it reaches exceptionally high population densities, is capable of expanding its range very quickly, and both outcompetes and consumes many species of native lizards.[3][4][5] The brown anole's introduction into the United States in the early 1970s[6] has altered the behavior and triggered a negative effect on populations of the native Carolina anole (Anolis carolinensis, also known as the green anole), which have generally been relegated to the treetops. -Wikipedia
