AMERICAN CETACEAN SOCIETY:DISTRIBUTION AND MIGRATION:
The orca is found in all the oceans of the world, though they are more abundant in cooler waters.

They are one of the few species of whales that move freely from hemisphere to hemisphere.
Are there any documented incident involving orca and divers or swimmers?
