A team of evolutionary biologists has shown that Anolis lizards, or anoles, are able to breathe underwater with the aid of a bubble clinging to their snouts. Some anoles are stream specialists, and these semi-aquatic species frequently dive underwater to avoid predators, where they can remain submerged for as long as 18 minutes. The researchers termed the process 'rebreathing' after the scuba-diving technology.
