Orcas (or killer whales) 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. [1] In captivity, there have been several non-fatal and four fatal attacks on humans since the 1970s. [2]
Although resident orcas have never been observed to eat other marine mammals, they occasionally harass and kill porpoises and seals for no apparent reason.
