Deepest polar bear (white bear)

Up to 6 m (20 ft) – While underwater, the polar bear (Ursus maritimus) shuts its nostrils and flattens its ears but its eyes stay open to spot prey. Hunting dives are rare since the polar bear is typically a stealth predator and because its coat is highly buoyant. The polar bear is the largest land carnivore, and because its habitat is largely devoid of vegetation, it is the most carnivorous of all bear species. It can remain underwater for over three minutes and swim for hundreds of kilometres. It has no natural predators and does not fear humans, especially seal-like divers, which makes it a very dangerous animal. The polar bear is known as nanook by the Inuit.


EDITOR’S NOTE
Videographer Mario Cyr has observed more than 30 bears underwater in the Canadian Arctic. None of the bears observed by Cyr ever dove beyond 6 m (20 ft), including aggressive bears that chased him underwater. As of 2017, claims of deeper dives by polar bears are unsubstantiated.
