Are narwhals freshwater or saltwater?
It appears narwhals prefer the freshwater coming off still, serene glaciers over the silt-filled runoff that gets discharged from very active glaciers.
What ocean do narwhals live in?
Arctic Ocean
About the Species. Narwhals are found in the Arctic Ocean. Generally male narwhals have a tooth that grows into a long clockwise-spiraled tusk, resembling a unicorn horn. Narwhals, like all marine mammals, are protected under the Marine Mammal Protection Act.
Can narwhals live in warm water?
Narwhals live in water that is at a fairly steady temperature around freezing point all year round. Whales such as narwhals live their whole lives in frigid water being always able to maintain a constant warm mammalian body temperature.
Do narwhals swim in the ocean?
Diving far below the water’s surface, narwhals feed on squid, shrimp, octopus, arctic cod and Greenland turbot. Scientists have place geotracking tags on narwhals and observe that they can swim to the ocean floor in a corkscrewing motion and will flip over to swim on its other side.
Are narwhals born in eggs?
5. Female Narwhals will give birth to a single calf once every 3 years, with gestation periods lasting about 14 months. They give birth during the months of summer and early fall. At birth, Narwhal calves are approximately 5 ft (1.5 m) and weigh about 2,200 lb (1,000 kg).

Where do narwhals live in the Arctic Ocean?
2. Where do narwhals live? Unlike some whale species that migrate, narwhals spend their lives in the Arctic waters of Canada, Greenland, Norway and Russia. Most narwhals winter for up to five months under sea ice in the Baffin Bay-Davis Strait area.
Is the narwhal a deep water cetacean?
The narwhal is a deep-water cetacean, and has been known to dive to 1,200 feet. It has up to 4″ of blubber under its skin, which is needed for protection in the cold arctic waters. Becoming trapped in forming ice is not uncommon; in Greenland such an entrapment is called a “savssat”.
What do Narwhals do in the summer?
During the summertime in the northern Arctic bays and fjords, male narwhals can be seen interacting at the surface, carefully crossing their tusks and touching them together. Such behavior might help adult males compare themselves and maintain dominance hierarchies.
Why are narwhals important to Greenland and Canada?
In order to understand how narwhals may or may not adapt to the climate change in the Arctic, it is vital to develop a basic understanding of their ecology. Furthermore, narwhals are an important cultural, nutritional and economic resource for native communities in Greenland and Canada.
