The Monodon monoceros, commonly known as the narwhal, is a marine mammal found primarily in Arctic waters. It is famous for its long, spiral tusk, which is an elongated upper left canine tooth. Narwhals are social creatures, often found in pods, and they feed on fish, shrimp, and squid. They play a crucial role in the Arctic ecosystem by controlling prey populations and being prey for polar bears and orcas.

Monodon monoceros, commonly known as the narwhal, is native to the Arctic regions. It is primarily found in the Arctic waters surrounding Greenland, Canada, and Russia. Narwhals inhabit the Atlantic sector of the Arctic Ocean, including Baffin Bay, the Greenland Sea, and the Canadian Arctic Archipelago.

Narwhals are adapted to cold, icy environments. They are typically found in deep coastal waters and are known to frequent areas with heavy pack ice. During the summer, narwhals are often found in shallow bays and fjords, while in the winter, they migrate to deeper offshore waters covered with dense ice.

Narwhals occupy a specific niche as medium-sized cetaceans that rely on sea ice for breeding and protection from predators. They primarily feed on fish, squid, and shrimp, using their long tusks to detect and capture prey beneath the ice. Narwhals are also known for their deep diving abilities, often reaching depths of over 1,500 meters to forage for food.
