In the tropical forests of southern Costa Rica, a small, semi-aquatic lizard has evolved an unusual survival technique. Water anoles create a bubble over their nostrils to breathe underwater and avoid predators,

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.
