Polar bears are all left handed.

Polar bears are found across the Arctic including Arctic Canada, Greenland, Svalbard, and on the sea ice covering the North Pole. They can travel immense distances on foot and can swim lengthy journeys between ice floes searching for food. Mostly their diet consists of seals, also scavenging whatever washes up on shore, such as dead whales or fish.

Normally the largest land predator is solitary, and the mother with cubs will keep away from predatory males. Only when there is a large source of scavenging will several bears meet; in the past year a grizzly was seen picking at a whale carcass with its larger cousins. The two types of bear have been known to interbreed.

Polar bears have colourless fur and the black skin under it traps the sun's heat. Subcutaneous fat and air pockets in the fur layer, help to retain heat.

The bears will lie in wait for a seal at an ice hole during winter, because seals need to come up to breathe. The bear will grab it with the powerful and heavily clawed left paw and pull it up out of the water onto the ice. Alternatively, the bear will smell out female seals as they make a den in the snow to bear a pup. The seal always digs herself an escape tunnel so she can flee if she hears a bear digging. Seals eat fish which store oil in their bodies or livers, and this contains vitamin A which accumulates, and a polar bear will have eaten so many seals, its liver is toxic to eat. This dependence on ice to hunt, means polar bears are endangered as climate change is melting the sea ice.

We do not know why the bears are left-pawed. Maybe left-pawed bears are better at catching seals.
