What does the shark say? Click, click, click
Briefly

Researchers from the University of Auckland discovered that the rig shark, a New Zealand native, makes a clicking sound, potentially indicating a stress response. The sound was recorded accidentally during a study focused on shark hearing. This finding is significant as it enhances understanding of shark behavior and communication, challenging previous assumptions about their acoustic abilities. Lead researcher Carolin Nieder expressed surprise, noting that sharks hadn't been documented making sounds before, providing a new layer of complexity to their mysterious nature.
The discovery was purely accidental; the rig shark, native to New Zealand, occasionally makes a clicking sound that may suggest a stress response.
I didn't expect sharks to make sounds at all. Then, one day, I heard a clicking sound coming from one of the sharks. I was like, oh my God.
The sharks did not make any noise when swimming, meaning that the clicking could be a stress response.
No one had really heard a shark making sounds before, adding a layer of complexity to the already mysterious creatures.
