Although the narwhal and the beluga are classified as separate genera, with one species each, there is some evidence that they may, very rarely, interbreed. The complete skull of an anomalous whale was discovered in West Greenland c. 1990. 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. [12] Narwhal management today poses a challenge as governments and communities seek to balance conservation with cultural and subsistence requirements. How do scientists find them and study them?

The narwhal is most closely related to the beluga whale. Together, these two species comprise the only extant members of the family Monodontidae, sometimes referred to as the "white whales". The Monodontidae are distinguished by their medium size (at around 4m (13.1ft) in length), pronounced melons (acoustic sensory organ), short snouts and the absence of a true dorsal fin. [10]
According to Richard, a slanting wear pattern frequently found on the tips of tusks could offer an important clue to one of their uses.Narwhals are not endangered. They are listed as Least Concern (LC) on the IUCN Red List, with numbers estimated at around 123,000 mature individuals. However, they were listed as Near Threatened (NT) from 2008-2017 and still face several threats that could affect their numbers in the future. These include hunting, entrapment, climate change, pollution, human activity, and noise. Where do narwhals live?

Do Narwhals Have Magic?Hunting narwhals has long been a tradition for these communities, but there is growing concern about dwindling populations. In Ittoqqortoormiit, the main narwhal hunting location in east Greenland, the narwhal population dropped from 1,900 in 2008 to around 400 in 2016. Many scientists and researchers believe hunting should reduce or stop entirely to prevent populations from dropping further. Entrapment Narwhals are small, toothed whales found along coasts and rivers in the Arctic and are famous for their single large tusk. These tusks appear primarily on males and grow continuously throughout their lives—reaching lengths of up to three and a half meters. A narwhal tusk is made out of ivory and actually begins as a tooth—one of two with which narwhals are born.
