POLAR BEARS

Christmas time in Brazil is a Summer event.. We don't have snow and usually

 on Christmas Eve we have to turn on our air conditionning system! I  would

"Polar bear, common name for a white bear found on the sea ice of the

 Arctic throughout the North Polar basin. The only marine bear, it is longer

than other bears and streamlined for aquatic life. It has the plantigrade feet

(heel and sole touching the ground) typical of bears, with five sharp, curved

 claws on each foot for grasping the ice and holding its prey.  Long hair

between the pads protects the bear's feet from the cold and provides traction

 on  the ice. Stiff hairs on the forelegs, and very broad front feet, help the bear swim. All polar bears are white, although their fur may yellow in the summer

The largest wild bears ever weighed—more than 800 kg (1760 lb)—have been polar bears. However, most male polar bears weigh an average of about 350 kg (about 880 lb), and most females weigh about 250 kg (550 lb). Polar bears have a strong navigational sense, an extremely good sense of smell, and they are unusually clever at solving problems

in order to obtain food. They eat primarily ringed seals, and occasionally bearded seals, walruses, or white whales. They also feed on berries, sedges, mussels, and kelp. As with other true bears, polar-bear mothers and young form strong bonds. The young are very small when born: about 1 kg (about 2 lb). Their  eyes reamin closed for about
