 The dewlap is often larger in males; in some species only the male has a dewlap.In a few there are differences in the shape of the nose, but this is only known to be prominent in the proboscis and leaf-nosed anoles, which both have long-nosed males and more normal looking females (it is likely that something similar can be seen in smooth anole, but the female of that species is still unknown).A less obvious difference between anole sexes is the enlarged post-cloacal scales in males.
