Nearly all species of anole, including the Anolis sagrei, have a dewlap on their throat. [40] The dewlap can be used as a means of identifying specific species within the Dactyloidae family. [ 41 ] This is useful for not only mate selection between male anoles, but also to ensure the female is indeed mating with an individual within their own ...
In addition to colors that are visible to humans, dewlaps can have ultraviolet reflectance, which is visible to anoles. [90] The striped anole is the only species where it is asymmetrically colored, being brighter on one side than the other. [96] In some species even juveniles have a dewlap.
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.
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
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.
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. These dewlaps are usually of a different color from the rest of their body and, when enlarged, make the lizard seem much bigger than it really is.
Though A. auratus presents a variety of physical characteristics based on geographic location, maturity, and sex, a common feature is a tan-coloured back with cream or dark brown to black lateral stripes, copper orange spots on the posterior thigh, a bright orange tongue, as well as an overall tan tail with light gray or black streaks, blotches, or stripes on the dorsal surface but orange ...
