Deathroll

Deathroll is a term used to describe a specific predatory behavior observed in some crocodilians, most notably crocodiles and alligators. When a crocodilian captures prey, particularly larger animals, it will often engage in a death roll. This involves the animal rapidly spinning its body, usually around its longitudinal axis, while still holding the prey in its jaws. The primary purpose of the death roll is to dismember the prey, making it easier to swallow. By twisting and tearing, the crocodilian can break off manageable pieces from the carcass. Another proposed function is to drown the prey if it is a terrestrial animal, preventing it from struggling and escaping. The immense power and momentum generated by the crocodilian's body during the roll are sufficient to overcome the resistance of even large prey. This technique is particularly effective in water, where the crocodilian has more freedom of movement and the buoyancy can aid in the tearing process. The effectiveness of the death roll contributes significantly to the success of crocodilians as apex predators in their aquatic and semi-aquatic environments.
