Killer whales (or orcas) are powerful predators capable of killing prey much larger than humans, such as leopard seals and great white sharks. They have also been recorded preying on usually terrestrial species such as moose swimming between islands.However, wild orcas are not considered a real threat to humans, as there are few documented cases of wild orcas attacking people, and no fatal encounters.In captivity, however, there have been several non-fatal and fatal attacks on humans since the 1970s.Experts are divided as to whether the injuries and deaths were accidental or deliberate attempts to cause harm.
