They have a flattened body and head, slightly compressed tail, pointy snout, short legs, and large toe-pads. Males and females both have a yellow dewlap, a flap of skin hanging below the neck. Male dewlaps are generally larger than female dewlaps. [2] [3] Anolis evermanni on a beach Anolis evermanni with extended dewlap Brown Anolis evermanni
In a very small species like the Bahoruco long-snouted anole the home range can be as little is about 1.5 m 2 (16 sq ft) and 2.3 m 2 (25 sq ft) in a female and male, [99] compared to a large species like the knight anole where they average about 630 m 2 (6,800 sq ft) and 650 m 2 (7,000 sq ft). [49]
Female anoles do, however, often have a dorsal line down their back. Extension of the dewlap from the throat is used for communication. Males can form a pronounced dorsal ridge behind the head when displaying or when under stress. Females and juveniles have a prominent white stripe running along their spine, a feature most males lack.
Female water anoles reach sexual maturity at an earlier age than their male counterparts, and also have a smaller snout-anus length than males do at their sexual maturity. Males have a larger growth rate than females, and they reach a greater body size than females when they are of the same age.
This species of anole is a small lizard (or moderately-sized for an anole), adults measuring 40 to 44 mm (1.6 to 1.7 in) from snout to vent in males, [6] [19] in females to 46 mm (1.8 in). [19] The male does not have a dorsal crest or tail fin which is common in many of the anole lizards of Puerto Rico.
Many reptiles have dewlaps, most notably the anole family and Sitana genus of lizards, which have large skin dewlaps they can extend and retract. The anole family has been found to have enhanced vision for color and depth perception. [7] This family is able to see dewlap coloration from a distance, giving the dewlap use and importance.
The larger males have a bright green to yellow-green dorsal surface that is usually spotted or marbled with gray, brown, or black. Its ventral surface ranges from dull white to yellow to light green. Its dewlap is proportionately small for an anole, and is yellow or orange, occasionally with whitish scales. Females are smaller and duller ...
