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.
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.
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]
Anolis is a genus of anoles (US: / ə ˈ n oʊ. l i z / ⓘ), iguanian lizards in the family Dactyloidae, native to the Americas.With more than 425 species, [1] it represents the world's most species-rich amniote tetrapod genus, although many of these have been proposed to be moved to other genera, in which case only about 45 Anolis species remain.
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.
A medium-sized anole, adult males of A. bartschi have a typical snout-to-vent length of 7.5 cm (3.0 in) and females 6.4 cm (2.5 in). [3] It is one of only two anoles that completely lack a dewlap (both sexes), the other being the Cuban stream anole ( A. vermiculatus ).
