Animals have evolved all manner of methods to evade danger. For one lizard species living in the tropical forests of Costa Rica, their unique escape tactic involves a makeshift oxygen tank that allows them to hide underwater nearly as long as the Guinness World Record for a human holding their breath.

A particular type of semi-aquatic lizard has something truly unique to show us about the art of survival with air bubbles underwater.

A semiaquatic lizard called a diving anole produces a special bubble atop its head to breathe underwater and avoid predators on land, according to research.

New research reveals that scuba-diving lizards, described as "the chicken nuggets of the forest," use a bubble to breathe underwater

A species of semi-aquatic lizard produces a special bubble over its nostrils to breathe underwater and avoid predators, according to new research from Binghamton University, State University of New York.

When the lizards feel threatened by a predator, they dive underwater and produce a bubble over their heads to breathe.

Little lizards that wear snout bubbles underwater really do seem to be using them as tiny scuba tanks. Water anoles (Anolis aquaticus) made headlines a few years ago when they were caught proudly holding onto shiny pockets of air while submerged in their Costa Rican streams.

In the tropical forests of Costa Rica, a small lizard uses its own form of scuba gear — an air bubble on its head that allows it to breathe underwater for extended periods 1. Although many small invertebrates use bubbles for underwater respiration,

To investigate whether bubbles play a crucial role in underwater respiration, Dr Swierk conducted an experiment where she applied a substance to the skin of some lizards to prevent bubble formation, while leaving a control group untreated.

The assistant research professor of biological sciences at Binghamton University studies Anolis aquaticus, the lizard best known for being semi-aquatic, color-changing and 5 to 8 inches long (13 to 20 centimeters.
