Adult narwhals are pale gray or light brown on the dorsal side, white on the ventral side, some with spotted patterns. Narwhals have 2 teeth located in the upper jaw; in males, the left tooth will grow to form a long straight tusk, hence the nickname “unicorn of the sea.” The length of the tusk is between 1/3-1/2 as long as the length of the body.

The narwhal (Monodon monoceros) is a species of toothed whale native to the Arctic. It is the only member of the genus Monodon and one of two living representatives of the family Monodontidae. The narwhal is a stocky cetacean with a relatively blunt snout, a large melon, and a shallow ridge in place of a dorsal fin.

The narwhal (Monodon monoceros) is an Arctic species of cetacean. It is one of two species of white whale in the Monodontidae family (the other is the beluga whale). Narwhals are generally pale with brown speckles in color, though the neck, head, and edges of the flippers and fluke are nearly black. Older animals are usually more brightly ...

Narwhals are midsized toothed whales that are closely related to white whales. The most conspicuous feature of the narwhal is the up to three metres long spiralled tusk, borne by males of the species. The distribution of narwhal is largely confined to the North Atlantic region.

The narwhal has mottled pattern pigmentation with blackish-brown markings over a white background. The narwhals are born dark but become white as they age, with patches developing on the navel and genital slit when they reach sexual maturity. The oldest male narwhal is almost pure white as they change color with age. Narwhals do not have a ...

They have white, green and brown speckles and a long ridge down their backs to their tail (flukes). They have small eyes. Males have one, long, ivory tusk that can reach 9 feet long. New research suggests this tusk may have a sensory role for the whale — it may help them sense things in the water.

The narwhal is a medium-size odontocete, or toothed whale. Some people think that its long, spiral tusk is the source of the myth of the unicorn. It has a thick layer of blubber and no fin on its back, which make it possible for the narwhal to live in the extremely cold waters of the Arctic and to move freely under ice.

Often dubbed the unicorns of the sea, narwhals have long tusks protruding from their heads. Learn about narwhals, as well as the threats this species faces, what WWF is doing to protect its future, and how you can help.

Narwhal means "corpse whale" in Old Norse; this is perhaps a description of their skin, which is bluish-gray with white blotches (young narwhals are brown). Narwhals have a cylindrical body (with no dorsal fin) and a round head with a small mouth on their blunt snout.

Physical Description: Its tusk is the animal’s most obvious physical attribute. The body is somewhat stocky with a rounded, relatively small head. Color: Color varies with age, from dark blue-gray in juveniles to brown-gray in adults. The dorsal region is covered with leopard-like spots.
