A team of University of Copenhagen researchers has compiled the first and only evidence that narwhals and beluga whales can breed successfully. Les baleines boréales natives de la région du détroit de Lancaster forment la population dite de l’Est du Canada et de l’Ouest du Groenland, qui totalisait quelque 7300 individus en 2005. DNA and stable isotope analysis of an anomalous skull from the Natural History Museum of Denmark has allowed researchers to confirm the existence of a narwhal-beluga hybrid.For nearly thirty years, a strange-looking whale skull has gathered dust in the collections of the Natural History Museum of Denmark.
En juin, le béluga suit le retrait de la glace et passe les mois d’été dans la région du détroit de Lancaster.Les fjords et les estuaires du détroit de Lancaster assurent un habitat idéal aux bélugas pour l’alimentation, la mue et la mise bas durant l’été.

And despite constant monitoring of these and other whale populations by experienced hunters, government agencies and biologists, there are no reports of other oddballs, not even rumors, Dr. Heide-Jørgensen says.Still, the chances that this occurred only once in a million years and they just happened upon the skull are slim, said Dr. Lorenzen.For now, it’s only possible to speculate about the circumstances that led to the conception of the baby beluga narwhal, perhaps the cutest-sounding animal that ever existed. But the teeth were markedly different. Narwhals … They looked like a mix of narwhal and beluga, but with too many for a narwhal, too few for a beluga.The hunter told the scientist that the skull had belonged to a strange animal he’d killed in the late 1980s. The narwhal is characterized by its long, spiraled tusk and has a greyish-brown, mottled pigmentation, whereas belugas have two rows of uniform teeth, and adults are completely white.

"This whale has a bizarre set of teeth. The skull came from one of the few places on Earth where narwhals and belugas … While they are each other's closest relatives and roughly equal in size, the two species differ in their morphology and behaviour. The whales roam between west Greenland and Canada, spending their winters far offshore in Davis Strait and Baffin Bay.
