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]

They can be trained in captivity and are often described as intelligent, [137] [138] although defining and measuring "intelligence" is difficult in a species whose environment and behavioural strategies are very different from those of humans. [138] Orcas imitate others, and seem to deliberately teach skills to their kin.
