Covering its nose. Contrary to a legend among native hunters, polar bears do not cover their black noses while lying in wait for seals. Canadian biologist Ian Stirling, who has spent several thousand hours watching polar bears hunt, has never seen this behavior. Nor have other scientists.
Left pawed. Great white bears are not left-pawed. Scientists observing the animals haven't noticed a preference. In fact, polar bears seem to use their right and left paws equally.
Use of tools. Polar bears do not use tools, including blocks of ice, to kill their prey. Scientist Ian Stirling believes that this idea may have come about because, after failing to catch a seal, a frustrated and angry polar bear may kick the snow, slap the ground—or hurl chunks of ice.
Hollow hair conducts UV light. A polar bear's hollow hairs do not conduct ultraviolet light to its black skin. This theory was tested—and disproved—by physicist Daniel Koon.
Symbiosis with arctic fox. Polar bears do not share food with arctic fox in exchange for the fox's warning system. Zoologists discredit the notion. Arctic fox do travel behind polar bears and scavenge on scraps. In fact, foxes often annoy bears by nipping at their heels in an attempt to drive a bear off its prey. Polar bears sometimes lunge at or slap a fox. During the spring season when both polar bears and arctic fox hunt ringed seal pups, they can be considered competitors.
Orca whale predation. Scientist Ian Stirling concedes that an orca might have an opportunity to attack a bear stranded on a remnant of ice, but it’s extremely unlikely. Neither Stirling nor polar bear biologist Scott Schliebe have ever heard of this being observed.
Bi-polar bears? Polar bears live only in Arctic areas that surround the North Pole—not in Antarctica, which surrounds the South Pole. School children often see illustrations of penguins and polar bears together, but this could never happen. In fact, the word arctic comes from the Greek word for bear, and Antarctic comes from the Greek meaning the opposite, without bear.
