Narwhals have also recently been moving further west in the Canadian Arctic, perhaps due to changes in sea ice cover, and they have been sighted and hunted near communities in the Central Canadian Arctic where they have seldom been seen before (White 2012). Disturbances

Narwhals are usually found in groups of 15 to 20, but herds of several thousand have been seen. Newborn narwhal calves are about 1.6 metres (5.2 feet) long. Calves are weaned after a year or more; females reach sexual maturity at about six years and males at eight. Female narwhals experience menopause, and a significant portion of their life is spent in a post-reproductive phase. The longest-lived narwhals are likely between 105 and 125 years old. a b c Laidre, K (2004). "Deep-ocean predation by a high Arctic cetacean".

Bibcode: 2003MEPS..261..269L. doi: 10.3354/meps261269. 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. Smaller entrapments occurred in Inglefield Bredning in Northwest Greenland in November 2009 and February 2010. Again, this is normally summer habitat for narwhals and they are thought to leave the area well before November. Again, seismic activity in Baffin Bay in September and October 2009 may have delayed or prevented their migration from the area. Further research is needed

Narwhals can live up to 50 years [ inconsistent] and often die by suffocation after being trapped due to the formation of sea ice. Other causes of death, specifically among young whales, are starvation and predation by orcas. 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". More recent estimates list higher populations (upwards of 170,000), thus lowering the status to " least concern". [4] Narwhals have been harvested for hundreds of years by Inuit in northern Canada and Greenland for meat and ivory and a regulated subsistence hunt continues.

In 2019, the Greenland Climate Research Centre began a pilot study to monitor narwhals and glacier fronts with automated cameras ( National Progress Report Greenland 2019). Current projects During growth, the narwhal accumulates metals in its internal organs. One study found that various metals are lightly concentrated in the blubber and densely concentrated in the liver and the kidneys. Zinc and cadmium are found in higher concentration in the kidney compared to the liver; the inverse is true for lead, copper and mercury. Certain metals were correlated with size and sex. During growth, it was found that mercury accumulated in the liver, kidney, musculature, and blubber, and cadmium also settled in the blubber. [60] Aerial surveys were conducted over the eastern part of the North Water polynya in April 2014. The resulting estimates suggested that 3,059 narwhals (95 % CI: 1,760–5,316) wintered in the eastern part of the North Water polynya during this time (Heide-Jørgensen et al. 2016). Narwhal sightings were also recorded during a 2018 multi-species survey of the North Water, with 23 narwhal sightings recorded. Inglefield Bredning Did you know that a narwhal’s “tusk” is actually a long, spiral tooth? It protrudes from male narwhals’ upper jaws. While its exact purpose is not fully understood, scientists’ research shows it may play a role in communication, navigation, hunting or mate selection. Despite its impressive size, the tusk is actually a sensitive sensory organ, containing millions of nerve endings that can detect changes in water temperature, pressure and salinity.

A rough estimate for the total world population is 85,000 – 100,000 animals (White 2012, NAMMCO 2017). A more detailed breakdown of the population status in different areas of the Arctic is given below. Svalbard-Northwest Russian Arctic The narwhal has been hunted by the Inuit for many thousands of years. Almost every part of the narwhal is used. The blubber and oil are good for lighting and cooking. The meat provides an excellent source of vitamin C that is otherwise difficult to obtain in the Arctic. And the tusks are used to fashion spears and harpoons. The practice is still maintained in many parts of the Arctic. a b c d e Hoover C, Bailey M, Higdon J, Ferguson SH, Sumalia R (March 2013).

Hybrids have been documented between the narwhal and beluga (specifically a beluga male and a narwhal female), as one, perhaps even as many as three, were killed and harvested during a sustenance hunt. Whether or not these hybrids could breed remains unknown. 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. [46] [47] Lifespan and mortality A polar bear scavenging a narwhal carcassNarwhals are one of the many species of mammals that are threatened by human actions. [59] Estimates of the world population of narwhals range from around 50,000 (from 1996) [38] to around 170,000 (compilation of various sub-population estimates from the years 2000–2017). [4] They are considered to be near threatened [ inconsistent] and several sub-populations have evidence of decline. In an effort to support conservation, the European Union established an import ban on tusks in 2004 and lifted it in 2010. The United States has forbidden imports since 1972 under the Marine Mammal Protection Act. [59] Narwhals are difficult to keep in captivity.
