Speckled Anole, Anolis aeneus (Gray)

Distribution. Anolis aeneus is endemic to Grenada and the Grenadines, its populations in Trinidad and Tobago (as well as Guyana) are introduced.

Males reach a body length of 77 mm, females are smaller reaching about 55 mm. Coloration is usually gray, olive, or chocolate-brown, mottling or speckles. Note that it has a bluish eye which will distinguish it from most other Anolis on Trinidad and Tobago.

Natural History. Anolis aeneus uses a wide range of habitats including open areas (Hailey et al., 2009), with substrates of mainly bushes and walls (White & Hailey, 2006) and it is usually seen in urban areas in Trinidad and Tobago. However we have found it in disturbed secondary forests on Tobago.
