The Jamaican anole (Squamata: Polychrotidae: Anolis grahami), also known as Graham’s anole, is one of seven native species of anole lizards found on the island of Jamaica. Females like the one shown here are relatively drab, sporting little more than black and white lines across the spines of their pale green-brown bodies. Males, in contrast, are colored with vivid blue and green, and can extend bright orange dewlaps to attract females.
In 1905 these anoles were introduced to the islands of Bermuda to control fruit flies, and since then they have become the most common lizards found there. They have been so successful on Bermuda that they have out-competed and displaced the native Bermuda rock skink (Squamata: Scincidae: Plestiodon longirostris), leading it to be listed as “critically endangered.” Antiguan anoles, Barbados anoles, and perhaps geckos have since been introduced to Bermuda as well, increasing the pressure on native rock skinks to survive.
