The Giant Anole is native to Jamaica, being introduced to Miami in the 1970s. Despite its name, this "giant" rarely exceeds 10 cm snout-vent length and never gets as big as the Knight Anole. It is usually found high in the canopy and eats a variety of foods, similar to the Knight Anole. This species is uniformly green, but can turn dark brown like other anoles. Both males and females have yellow dewlaps with male throat fans being somewhat larger
Similar in color to the Green Anole (being bright green), the Giant Anole is somewhat larger, has a spiny crest along its neck and back, has yellow around its eye, and has a yellow dewlap, not pink like the Green Anole. It can also be confused with baby Green Iguanas (Iguana iguana) which have shorter, blunter snouts and stripes on the tail.
