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

Swierk applied a substance to the lizards’ skin that prevented bubble formation. Without air bubbles, the lizards couldn’t stay underwater as long as usual: they surfaced about 30% — or about 67 seconds — sooner than lizards that could form bubbles.
