They are found in Arctic and subarctic waters, predominantly around Greenland, Canada, Norway and Russia but also as far south as New Zealand. Due to the extreme cold of the arctic waters, they have significantly more blubber than an average whale, which usually has between 20-30% fat. [15][39][37][36] Due to the lack of well-developed dentition in the mouth, narwhals are believed to feed by swimming towards prey until it is within close range and then sucking it with considerable force into the mouth. Powell (Peter Folkens illustrator). [12], The white whales, dolphins (Delphinidae) and porpoises (Phocoenidae) together comprise the superfamily Delphinoidea, which are of likely monophyletic origin.

[27][28][29][30] The rubbing of tusks together by male narwhals is thought to be a method of communicating information about characteristics of the water each has travelled through, rather than the previously assumed posturing display of aggressive male-to-male rivalry. It is hollow and weighs around 10kg (22lb). The narwhal, or narwhale (Monodon monoceros), is a medium-sized toothed whale and possesses a large "tusk" from a protruding canine tooth. One threat to Narwhals and their habitat is global climate change. [38] Narwhals from Canada and West Greenland winter regularly in the pack ice of Davis Strait and Baffin Bay along the continental slope with less than 5% open water and high densities of Greenland halibut. [4] They are considered to be near threatened and several sub-populations have evidence of decline. (Owl House), told The Narwhal in an interview. The complete skull of an anomalous whale was discovered in West Greenland circa 1990. (Monodon monoceros) Narwhals are midsized toothed whales that are closely related to white whales. II. The tusk can grow to 9 feet (3 meters) long and weigh more than 22 pounds (10 kilograms). The other species at risk Ontario has observed so far include an endangered minnow called a redside dace, seven types of birds and the butternut tree. A year later, the percentages of both animals in the diet of narwhals had changed. Greenland harvested more, 700900 per year, in the 1980s and 1990s. [15], At times, a bull narwhal may rub its tusk with another bull, a display known as "tusking"[28][36] and thought to maintain social dominance hierarchies. The unusual dentition seen in the single remaining skull indicates the hybrid hunted on the seabed, much as walruses do, indicating feeding habits different from those of either parent species. Narwhal eat flatfish and halibut during the restricted winter months, which can both be found on the bottom of the sea in the Baffin Bay and Davis Strait. They use echolocation to help them find food and have an interesting way of eating creating a sort of vacuum and sucking up their food. The narwhal is an Arctic-based whale that spends most of its life in the waters off Greenland, Svalbard, Russia, and Canada. As previous estimates of the world narwhal population were below 50,000, narwhals are categorised by the International Union for Conservation of Nature (IUCN) as "nearly threatened". [8], During growth, the narwhal accumulates metals in its internal organs. These legendary animals have two teeth. [70] In 1555, Olaus Magnus published a drawing of a fish-like creature with a horn on its forehead, correctly identifying it as a "Narwal". The deeper a Narwhal dives, the faster their healing rate. The narwhals mouth is virtually toothless. During the summer, narwhals eat mostly Arctic cod and Greenland halibut, with other fish such as polar cod making up the remainder of their diet. [8] The northernmost sightings of narwhal have occurred north of Franz Joseph Land, at about 85 North latitude. (ed.). The narwhal is the unicorn of the sea, a pale-colored porpoise found in Arctic coastal waters and rivers. They have evolved to withstand extreme ice, rather than warmer climates. Old males may be almost pure white. Walker's Mammals of the World. IV. Because vertical distribution of narwhal prey in the water column influences feeding behaviour and dive tactics, regional differences in the spatial and temporal patterns of prey density, as well as differences in prey assemblage, may be shaping winter foraging behaviour of narwhals. Verne thought that it would be unlikely that there was such a gigantic narwhal in existence. The narwhals tusk is actually a tooth with millions of nerve endings inside it, meaning they can use it to feel or taste. It is the only member of the genus "Monodon". Lightboxes.

The genome consists of 37.9% repetitive elements and encodes 21,785 protein-coding genes (similar to many other mammals). Narwhals have a blotchy sausage-shaped body, a rounded head with no beak, a ridge on their backs rather than a fin and short blunt flippers with upcurled edges. [56], Narwhals are one of many mammals that are being threatened by human actions. It is possible that individual "bangs" are capable of disorienting or incapacitating prey, making them easier to hunt, but this has not been verified. Its name is derived from the Old Norse word nr, meaning "corpse", in reference to the animal's greyish, mottled . [9] This long lactation period gives calves time to learn skills needed for survival during maturation when they stay within two body lengths of the mother. [15] Male narwhals attain sexual maturity at 11 to 13 years of age, when they are about 3.9m (12.8ft) long. [9] The scientific name, Monodon monoceros, is derived from Greek: "one-tooth one-horn".

In 2002 there was an increase in narwhal catches by hunters in Siorapaluk that did not appear to be associated with increased effort,[64] implying that climate change may be making the narwhal more vulnerable to harvesting. They have a torpedo-shaped body, which is more hydrodynamic, allowing them to move through the water more swiftly. Narwhals can live up to 50 years and are often killed by suffocation after being trapped due to the formation of sea ice. Zinc and cadmium are found in higher densities in the kidney than the liver and lead, copper and mercury were found to be the opposite. It is a member of the Monodontidae family, which is itself part of a larger group of animals known as the ' toothed whales '.

It was described by marine zoologists as unlike any known species, but with features midway between a narwhal and a beluga, consistent with the hypothesis that the anomalous whale was a narwhal-beluga hybrid;[11] in 2019, this was confirmed by DNA and isotopic analysis. Instead, male narwhals have a single long, straight tooth (or tusk) that protrudes two to three meters out of the upper left jaw. Muktuk, the name for raw skin and blubber, is considered a delicacy. Who wrote the music and lyrics for Kinky Boots? [19][34] The varied morphology and anatomy of small teeth indicate a path of evolutionary obsolescence,[19] leaving the narwhal's mouth toothless.

Taxonomic notes. [25], Scientists have long speculated on the biological function of the tusk. They also emit tonal signals, such as whistles and pulsed calls, that are believed to have a communication function. [7] Its name is derived from the Old Norse word nr, meaning "corpse", in reference to the animal's greyish, mottled pigmentation, like that of a drowned sailor[8] and its summertime habit of lying still at or near the surface of the sea (called "logging").

[9] The narwhal vocal repertoire is similar to that of the closely related beluga, with comparable whistle frequency ranges, whistle duration and repetition rates of pulse calls, however beluga whistles may have a higher frequency range and more diversified whistle contours. Due to strong site fidelity, changes in weather and ice conditions are not always associated with narwhal movement toward open water.
