In Puerto Rico there are 12 native angle lizards.
Anoles are tree or grass lizards of medium size and sometimes of bright coloration.
The male angles are larger than the females, have larger heads, and a brightly colored dewlap. The dewlap is the sac on the male's throat. He inflates it at will to establish and defend his territory and to display for females. The dewlap display is often accompanied by push ups, head bobbing, tongue protruding and tail wagging. Sometimes males also erect a dorsal crest.
