Scientists Discover Clicking Sounds in Rig Sharks for the First Time
Sharks were long thought to be silent, but a surprising new study reveals that rig sharks can make clicking sounds when handled. Evolutionary biologist Carolin Nieder first discovered the clicks by accident during lab tests. These sounds—likely produced by snapping their flat teeth—occurred most often during initial handling, suggesting a stress or defense response. If confirmed in the wild, this could change how scientists understand shark communication. The study opens new questions about the acoustic capabilities and behavioral complexity of these ancient marine predators.
