wild. In contrast to many animals in zoos and aquariums, who often enjoy comparable if not better lifespans in captivity, killer whales have dramatically lower lifespans in captivity than they do in the wild: Wild whales of all sexes live only an average 8.5 years in captivity, while in the wild the average lifespan is 30 years for males, and 50 for females. Captive-born orcas have shown a high mortality rate as well.
