Brown Anole (molting)

This species is highly invasive.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. The brown anole's introduction into the United States in the early 1970's] has altered the behavior and triggered a negative effect on populations of the native Carolina anole (Anolis carolinensis), which have generally been relegated to the treetops.Wikipedia
