A new study from the
Professor Dinets observed that the boas hung down from the ceiling of the cave entrance and grabbed passing bats in midair. The scientist also noticed that if more than one boa was present, the snakes coordinated their positions in such a way that they formed a wall across the entrance.
The process made it difficult or unfeasible for the bats to pass without striking at least one boa.
The researchers stated that such hunts were always successful. The more snakes were present the less time it took each to capture a bat, added the researchers. However, if there was only one boa, it sometimes failed to protect a meal.
