It is where they have adapted to live
Arctic
From my research, I found out Narwhals live in the Arctic/Tundra biome :D
A depth of 4,500 feet/1,500 meters is the furthest down that a narwhal can live. But that depth only can be tolerated for 20-25 minutes at a time. That depth also is reached only in pursuit of narwhal prey of the lower, midnight zone of the Arctic and North Atlantic ocean waters. Typically, a narwhal favors the sunlit waters of the upper zone that goes down 600 feet/200 meters from the ocean surface.
Narwhals live in the Arctic waters of Canada, Russia, Norway, and Greenland.
No, I don't have a pet narwhal [Monodon monoceros] named Fred. Nor is it likely that anyone else has a pet narwhal named Fred. Narwhals live in Arctic waters off the northern Canadian, Greenland and Russian coasts; and in the northern Atlantic waters off the Canada and Greenland coasts. So it's prohibitively expensive for a pet store to collect, transport, and maintain the large sized narwhals. Additionally, the record of narwhal survival in environments other than their native habitat isn't encouraging to any narwhal pet store operator or narwhal pet owner. The narwhal is a picky eater and fussy habitat dweller. It favors a specialized diet of Arctic and polar fare, and a specialized environment of Arctic and polar cold waters and ice.

Narwhals only live in the Arctic ocean.
