Jamaican and Antiguan Anoles in Bermuda

The only endemic or native lizard in Bermuda is the Bermuda skink (Plestiodon longirostris), which is ground dwelling and has been driven to the edge of extinction. Three species of anole were introduced to Bermuda during the Twentieth Century, of which the Jamaican anole (Anolis grahami) is now ubiquitous throughout the archipelago, the Antiguan anole, or Leach's anole (Anolis leachii), known in Bermuda as the Warwick lizard, was once associated only with Warwick Parish, but has become more common throughout the central parishes, and the Barbados anole (Anolis extremus) remains scarce, and restricted to the West End of Bermuda. This video contains clips of only Jamaican anoles and Warwick lizards. Of the two, the Warwick lizard is larger, with an emerald back and light undersides. The Jamaican anoles have a greater degree of sexual dimorphism. The males are not only larger, but more brightly coloured. They are normally multi-hued, but when stressed they change colour to a very dark brown. The males of both species of anole have an extendable (bright orange in the case of the Jamaican) "dewlap" on their throats with which to signal dominance.
