Many of us have seen those classic wildlife documentaries of wolves or lions working in packs to chase down their prey.

But snakes?

A new study has revealed that Cuban boas coordinate bat hunts in the sinkhole caves of Cuba's Desembarco del Granma National Park.

It was already known that the reptiles hang from the ceiling at the cave entrance and catch Jamaican fruit bats that roost inside.

But Vladimir Dinets, a psychologist from the University of Tennessee at Knoxville, found that snakes position their bodies close together, closing off the bats' flight path and resulting in more successful captures. (Also see "Watch Snakes Grab Cave Bats From Mid-air.")
