Water anoles jump into streams when threatened and produce a bubble that helps them stay underwater for up to 20 minutes

Pencil-long lizards that plunge into streams to evade their predators survive underwater by breathing through a bubble that forms on their nostrils, researchers say.

Water anoles live around rocks and plants near streams and waterfalls in Central and South America and are preyed on by birds, snakes and other lizards, making life in the forest an often short affair.
