Orca attacks

Orcas are large, powerful aquatic apex predators. There have been incidents where orcas were perceived to attack humans in the wild, but such attacks are less common than those by captive orcas. In captivity, there have been several non-fatal and four fatal attacks on humans since the 1990s. Experts are divided as to whether the injuries and deaths were accidental or deliberate attempts to cause harm.

There are a few recorded cases of wild orcas "threatening" humans, but there have been no fatalities.

In the early 1910s, on Robert Falcon Scott's Terra Nova Expedition, one member of the expedition recorded that orcas had attempted to tip ice floes on which photographer Herbert Ponting and a sled dog team were standing.

There are anecdotal reports that, c. 1955, an Inuk man fell prey to an orca entrapped by ice in Grand Suttie Bay (Foxe Basin, Canada). A pod of orcas, likely 10-12 individuals, was trapped in a polynya, and a young man visited the site in spite of advice from elders to wait until the ice was strong enough. Two Inuit elders stated to a research team that one of the animals chased the young man, broke the ice under him, then killed and ate him. However, the researchers were not able to directly confirm this, as one of the elders clearly stated that he had not witnessed the event himself. The other elder did not clarify whether he had seen it happen. As the ice thickened, two to three whales were taken by Inuit hunters, and three more were harpooned but tore the lines (made of seal skin). The rest of the pod likely died of starvation or drowned.

In 1958, an orca attacked the fishing boat Tiger Shark after being struck with a harpoon off the coast of Long Island. The whale was able to get free and chased the vessel for some time. At one point he lifted the boat "clear out of the water".

In September 1962 in Washington waters off the west side of San Juan Island, Marineland of the Pacific collector Frank Brocato lassoed a female salmon-eating southern resident orca. When she and an accompanying male thumped his boat with their flukes, Brocato started shooting from his rifle, killing the female—the first of many southern residents to be killed in capture operations. Her body was towed to Bellingham to be rendered for dog food.

On June 15, 1972, the hull of the 13-metre-long (43 ft) wooden schooner Lucette was damaged by what was identified as a pod of orcas and sank approximately 320 kilometres (200 mi) west of the Galapagos Islands. Dougal Robertson and his family of five escaped to an inflatable life raft and a dinghy.

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. Because Kretschmer was wearing a black wetsuit and several sea lions were spotted in the area where the encounter took place, experts believe it was a case of mistaken identity.
