the terrifying hunting tactics of cuban boas revealed: group hunts form a \'wall of snakes\' across cave entrances to trap bats
They hang from the ceiling of the cave, and if there is more than one boa, they coordinate to form a wall at the entrance and catch the bats as they go in and out.
These findings are significant because snakes have long been considered individual hunters and diners.

It is one of the larger boa species.
They occur on the island of Cuba, found in tropical dry forests and bushes, where they can be found in caves, rock piles and cultivated land.
Many Cuban caves shelter large groups of bats, in some of which a small group of bats fly out at dusk and regularly hunt bats when Dawn returns.
Dr. Vladimir Dinets, a zoologist at the University of Tennessee, noticed that boas came up and down from the ceiling of the cave entrance and caught the bats as they flew.
Thus, he conducted a study in which, during the eight-day study, he observed a sinkhole cave in Cuba\'s desebuck del Grama National Park in Boas, Cuba
There are nine Boas living in the cave, each with a separate mark, which is easy to identify.
The ceiling of the cave is dotted with small objects to support climbers.
After sunset and before dawn, some boat people entered the passage connecting the bat habitat room and the entrance room to hunt by hanging from the ceiling and catching the passing bats.
Dr. Dinets collected all his visual observations with red light, laser changers and telescopes.
Every day during the observation, most or all boas spend the day around the cave entrance, most of the time in the room where hundreds of bats roost during the day.
Dr. Dinets wrote that it could be because that room was the warmest part of the cave at night, and/or because of the occasional discovery of dead bats there.
After analyzing the data, Dr. Dinets found that if there were more than one boa, the snakes would coordinate their location in a way that would cross the cave entrance, make it difficult or impossible for bats to pass without a distance of a boa.
He found that this kind of collective hunting is always successful, and the more snakes, the less time it takes to catch bats.
However, if there is only one boa, it can\'t eat at times.
So far, only a small number of snake species have been observed hunting in groups, and they coordinate with each other --
Or any other group-
Never been proved.
In addition, only a few of the world\'s 3,650 snakes are observed hunting in the wild.
So little is known about snake hunting tactics.
Collaborative hunting may not be uncommon among snakes, but requires a lot of very patient field research to discover, Dr. Dinets said.
But according to Dr. Dinets, Cuban boas is often hunted for food, and there may be pet deals, making it more difficult to observe them.
Dr. Dinets said, I suspect that if their number in the cave drops, they can no longer hunt in droves, even if some of them are not caught by hunters, they may
There are caves like this in the National Park, but poaching is everywhere.
