Research on interactions between sharks and cetaceans is limited, but a new video shows a shortfin mako shark circling a finless porpoise with a damaged tail.
The porpoise appeared healthy but couldn't swim properly due to the injury, and evidence like a bite mark indicates it may have been attacked by the shark.
This observation suggests that mako sharks might hunt live cetaceans more frequently than previously believed, despite mostly feeding on small fish and cephalopods.
