摘要

Catching prey might be one of the most difficult tasks that animals face every day. This task can be even more difficult for aquatic predators, whose prey can escape into three-dimensional space. Sharks and rays have developed a variety of hunting strategies, but one of their close relatives, the sawfish, has an adaptation that might simplify this daunting task - its saw. Our research has found that the saw is both a sensor to detect the sawfish's prey and also a weapon that is used to dismember prey.
