An intelligent lizard breathes underwater using an oxygen bubble stored on its nose.
Dr Lindsey Swierk had been studying the water anole for four years trying to work out how they stayed submerged for more than 15 minutes.
Filmed in Coto Brus, Costa Rica, observed the reptile’s nose bulged at the bridge every so often where an air pocket was based.
Dr Swierk, the Assistant Research Professor at Binghamton University, New York, said: “This behaviour opens up fascinating new doors that allow us to investigate how terrestrial animals adapt to aquatic habitats.
