Main article: Tusk This narwhal skull has rare double tusks. Usually, the canine tooth only on the left side of the upper jaw becomes a tusk. Rarely, males develop two tusks. This specimen, however, was of a female (Zoologisches Museum, Hamburg; collected in 1684) Heide-Jørgensen, M.P., Guldborg Hansen, R., Westdal, K., Reeves, R.R. and Mosbech, A. (2013c).

The narwhal probably evolved in the Pliocene period some two to five million years ago from toothed whales. The highly reduced vestigial teeth and the tusk are evidence of this. More distantly, all cetaceans evolved from hoofed land mammals perhaps beginning some 50 million years ago. The closest living relates are hippos, cows, and pigs, but the whale ancestors probably resembled a small deer-like the modern chevrotain. As it became accustomed to the marine environment, this ancestor began to evolve flippers and other specialized organs.

Narwhals show sexual dimorphism, with several differences between males and females. Adult male narwhals are on average longer and heavier than females, reaching a maximum length of about 460 cm and a maximum weight of 1,645 kg. Adult females have a maximum length of 400 cm and weight of 900 kg (NAMMCO 2013, Garde et al. 2007). a b c d e Hoover C, Bailey M, Higdon J, Ferguson SH, Sumalia R (March 2013). "Estimating the Economic Value of Narwhal and Beluga Hunts in Hudson Bay, Nunavut". The Arctic Institute of North America. 66: 1–16. The narwhal’s ivory spiral tusk is a truly impressive instrument. With almost 10 million nerve endings, it is an excellent sensory organ that can gather information about water pressure, temperature, and salinity. This horn actually develops from a large tooth and then protrudes through the upper lip of the skull to the left, giving it the appearance of a unicorn. Interestingly, the narwhal has two teeth. In most individuals, the second tooth usually remains undeveloped, but in very rare cases it has been known to grow into a second tusk from its skull.

Hunting occurs during the open water season from boats and from the floe edge during the fall, winter and spring. The timing of the hunt depends on the weather, the nature of the ice, and the movements of the narwhals. The timing of each of these depends on location. For example, Arctic Bay generally has a shorter hunting period (June–September) than Pangnirtung, which may run from March to November (Heide-Jørgensen et al. 2013b). Narwhales have a specialized diet of cephalopods and fish endemic to the Arctic. Less commonly, they will consume crustaceans. Information on narwhal sightings in the northwestern Russian Arctic (Barents and Kara Seas) comes mostly from the annual National Park “Russian Arctic” monitoring program, as well as opportunistic observations during oil/gas geological explorations, scientific expeditions, and tourist cruises. There is no abundance estimate for narwhals in this region. East GreenlandBest, R.C. (1981). "The tusk of the narwhal ( Monodon monoceros L.): interpretation of its function (Mammalia: Cetacea)".

In management area 1 – Ittoqqortormiit, Scoresby Sound and Blosseville Coast south to 68°30’N – the population assessment model estimated a small and depleted aggregation (down to only 18% of the historical population estimate). With an annual growth rate estimate close to zero, it was deemed unlikely that the aggregation could sustain any current removals (NAMMCO 2019a,b). Narwhals have a very long and robust life expectancy. It is estimated that they can live up to 50 years in the wild. The age of sexual maturity is not quite known, but it is likely to take up to nine years for males. The female conceives every two to three years on average, which ensures a constant supply of new calves. Population Heide-Jørgensen, M.P., R. Dietz, K. Laidre and P. Richard. (2002).

Much has been learned about the physical and seasonal habitat of narwhals through the application of satellite-linked tags. In such studies, narwhals are captured in nets and the tags are attached either to the tusk (in male narwhals) or by bolts through the dorsal ridge. The tags transmit data when the narwhal surfaces. Along with location, tags can collect data on diving and the time spent at specific depth intervals. To date, tagging studies have been conducted on almost all summer aggregations of narwhals in Canada and Greenland (Heide-Jørgensen et al. 2013b) and in Svalbard (Lydersen et al. 2007).

The narwhal was one of many species originally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. [7] Its name is derived from the Old Norse word nár, 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 scientific name, Monodon monoceros, is derived from Greek: "one-tooth one-horn". [8]
