Belugas are found in the Arctic and Subarctic regions, along the coasts of Alaska, Canada, Greenland, and Russia. These whales inhabit the Arctic ocean and the adjoining seas, like the Bering Sea, the Beaufort Sea, the Sea of Okhotsk, etc. They are also seen in the Baffin Bay, Hudson Bay, the Gulf of Alaska, and the Gulf of St. Lawrence. Beluga whales that inhabit the Arctic waters migrate when the sea freezes. During such times, they can be seen in some large rivers, like the Amur of Russia, and the St. Lawrence and Yukon rivers of Canada.
