Sharks can produce sounds. Scientists in New Zealand observed captive rig sharks (Mustelus lenticulatus) emitting clicking noises, marking the first documented instance of sound production in sharks. These clicks are believed to result from the sharks snapping their flat, blunt teeth together—a behavior previously unrecorded in these creatures. The purpose of these sounds remains uncertain; they may serve as a defensive mechanism or a response to being startled. This finding challenges the long-held perception of sharks as silent predators and opens new avenues for understanding their behavior and communication.
