Pack-hunting is a type of predation where several members of a species combine their efforts to increase their chance of success in the hunt. Well known pack-hunters are lions, wolves and army ants. Some pack hunters have tactics based on sophisticated teamwork, with each animal playing a specific role. Other pack-huntes are less organised, relying on weight of numbers to overwhelm prey rather than on a planned strategy.
