Bat Volcano Erupts at Night
Clip: Season 39 Episode 13 | 1m 56sVideo has Closed Captions
It's called the bat volcano because every night, it erupts.
More than three million bats live in the caves of Calakmul. To avoid being eaten by predators, they form a living tornado, or "bat volcano," when they fly. In this whirling mass, it’s almost impossible for their predators to choose a target.
