There are a few recorded cases of wild orcas "threatening" humans, but there have been no fatalities.
On September 9, 1972, Californian surfer Hans Kretschmer reported being bitten by an orca at Point Sur; most maintain that this remains the only fairly well-documented instance of a wild orca biting a human. His wounds required 100 stitches.
From 2020 to 2024, there were at least five hundred reports of orcas interacting with boats off the Atlantic coast of Spain and Portugal, an unusual and unprecedented behaviour. Some of these interactions involved orcas touching or damaging boats. The nudging, biting and ramming attacks concentrated on the rudders of medium-size sailing vessels sailing at moderate speed, with some impacts on the hulls. A small group of orcas were believed to be responsible, with three juveniles which have been named black Gladis, white Gladis, and grey Gladis identified as present for most attacks. No people were injured. The Portuguese coastguard banned small sailing vessels from a region where several incidents had been reported. It is thought by some that the behavior was playful, rather than aggressive or vengeful. However, Gibraltar-based marine biologist Eric Shaw argued that the orcas were displaying protective behaviors and were intentionally targeting the rudder with the understanding that it would immobilize the vessel, just as attacking the tail of a prey animal would immobilize it, a documented predation behavior.
While Tilikum has perhaps the most infamous reputation, there have been several other captive orcas that have repeatedly harmed people, intentionally or not.
