Graduate study, travel, work make me an expert in benthics, European languages, wildlife mapping, world fauna and flora. Narwhals live in the upper, sunlit zone of the Arctic and North Atlantic Ocean waters. It ventures down into the middle zone and even the topmost part of the lower zone. But these are merely forays for food.
The narwhal, or narwhale (Monodon monoceros), is a medium-sized toothed whale that possesses a large tusk from a protruding canine tooth. It lives year-round in the Arctic waters around Greenland, Canada, and Russia.It is one of two living species of whale in the Monodontidae family, along with the beluga whale.ike the beluga, narwhals are medium-sized whales. For both sexes, excluding the male's tusk, the total body size can range from 3.95 to 5.5 metres (13.0 to 18.0 feet); the males are slightly larger than the females. The average weight of an adult narwhal is 800 to 1,600 kilograms (1,800 to 3,500 pounds).
