Meet the water anole, a small lizard native to the tropics of Central America. While studying these anoles, researchers discovered that they could flee underwater and remain submerged for 16 minutes or more at a time. Curious to see how the lizard manages this feat, they filmed them underwater, discovering that the anole seems to exhale a small bubble that sticks on its face and then re-inhale it. 

How exactly this built-in “scuba gear” works is still under investigation.
Anolis aquaticus takes to the water as refuge from predators, swimming and often diving underwater for long periods of time.
To enable these crazy-long dives, it’s possible that anoles may have come up with a scuba-tank method of sorts to “breathe” underwater. 

As researchers continue to investigate this little aquanaut, it will be interesting to discover just what its secrets are!
