Footage that Swierk recently captured of submerged anoles shows prominent bubbles swelling and deflating on the reptiles’ heads. Diving anoles aren’t fast runners and rely mostly on camouflage to hide from predators such as birds, snakes, mammals and other lizards. For diving anoles, gular pumping may also play a part in circulating stored oxygen, affecting how long anoles can stay underwater. A throat-pumping action called gular pumping may play a part in circulating stored oxygen, affecting how long anoles can stay underwater. Another unresolved question is how diving anoles store and circulate oxygen while underwater.
