What layer of the ocean does a killer whale live in?
Killer whales live most of their life in the sunlight zone in the oceans, which near the surface. They have the ability travel further down into the twilight zone, although there isn’t much reason to stay there as the food sources they use are much closer to the surface. There is no credible record of any Killer whale going as deep as the midnight zone. These 3 zones are generally regarded to have lower depth limits of -300ft., -6000ft. and -12,541ft. respectively.
