Underwater Cameras Expose the Secret Lives of Whale Sharks

Camera tags attached to whale sharks revealed they feed across a much wider depth range than surface observations had suggested.

Researchers documented 36 distinct behaviors, including shallow krill feeding and slow foraging near the seafloor.

The footage shows whale sharks use multiple feeding strategies, not just surface-level filtering.

The findings fill key gaps on this endangered species and help explain how it adapts to patchy tropical food resources that may become less reliable with climate change.
