They are found in both the Arctic and the North Atlantic Ocean.
Here's a breakdown:
* Arctic Belugas: The majority of beluga populations live in the Arctic Ocean.
* North Atlantic Belugas: There are distinct populations of belugas that inhabit the North Atlantic, particularly in Canada's St. Lawrence River estuary and the waters off Greenland and Iceland.
So, while they are more common in the Arctic, beluga whales can definitely be found in the Atlantic Ocean!
