Their pads are rough so they don't slip on the ice. www.flickr.com Polar bear's paw at the Cincinnati Zoo
Polar bear claws are curved so they can dig into the ice when they make their den or when they walk. They also help them eat meat. www.flickr.com Copyright © Daniel Ruyle
Their nose helps them smell seals up to 20 miles away. If a seal is hiding under ice, then they can still smell them up to a mile away. Their nostrils close when they swim. www.flickr.com I will try to post a Polar Bear per day!
A polar bear uses its 42 jagged teeth to eat meat and hunt. www.flickr.com There are actually a few polar bears in this exhibit but this one drew my attention due to the exposure of teeth so I couldn't resist. They say that polar bears are on of the nastiest and meanest. I don't believe I'd like to come too close to those teeth myself.
Polar bears use their paws to swim. The front paws help them move and the back paws help them turn. www.flickr.com Polar bear @ everland.korea
They have tiny tails so that they do not get cold.

It shares this title with the Kodiak Bear. Adult males weigh 350–680 kg (770–1500 lbs) and measure 2.4–3 m (7.9–9.8 ft) in length. Adult females are roughly half the size of males and normally weigh 150–249 kg (330–550 lb), measuring 1.8–2.4 metres (5.9–7.9 ft) in length. When pregnant, however, they can weigh as much as 499 kg (1,100 lb). The polar bear is among the most sexually dimorphic of mammals, surpassed only by the pinnipeds. The largest polar bear on record, reportedly weighing 1,002 kg (2,210 lb), was a male shot at Kotzebue Sound in northwestern Alaska in 1960. The shoulder height of the polar bear is 130-160 cm (51-63 in). Polar bears have evolved unique features for Arctic life, including furred feet that have good traction on ice.Compared with its closest relative, the brown bear, the polar bear has a more elongated body build and a longer skull and nose. As predicted by Allen's rule for a northerly animal, the legs are stocky and the ears and tail are small. However, the feet are very large to distribute load when walking on snow or thin ice and to provide propulsion when swimming; they may measure 30 cm (12 in) across in an adult. The pads of the paws are covered with small, soft papillae (dermal bumps) which provide traction on the ice.The polar bear's claws are short and stocky compared to those of the brown bear, perhaps to serve the former's need to grip heavy prey and ice. The claws are deeply scooped on the underside to assist in digging in the ice of the natural habitat. Despite a recurring Internet meme that all polar bears are left-handed, there is no scientific evidence to support this claim. Unlike the brown bear, Polar Bears in captivity are rarely overweight or particularly large, possibly as a reaction to the warm temperatures of most zoos. The 42 teeth of a polar bear reflect its highly carnivorous diet. The cheek teeth are smaller and more jagged than in the brown bear, and the canines are larger and sharper.

Their fur isn't white, it is clear and hollow like a straw. This helps them blend in with the snow and ice. It also keeps them warm. Under the fur is black skin. www.flickr.com Flickr - Photo Sharing!
Polar bears slide on the snow for fun, but also because it helps them clean their fur. www.flickr.com Our three polar bears were greeted by 18 tons of snow and lots of smiling donors when they walked into their exhibit yesterday. Kalluk, the male, quickly bounded to the top of one snow mound and spread himself flat as a pancake, rubbing and wiggling in the snow. Females Tatqiq and Chinook started digging in the snow and eating the icy treat that filled their habitat. Soon, they were wrestling with each other, diving into their pool and belly-crawling across the slippery ice. The bears even found some of their other toys and buried them in holes they dug in the snow.
Male polar bears can be taller than the ceiling in a house and the females be as tall as a man. They stand up to fight or look for food. www.flickr.com Explore Cherylmarie1's photos on Flickr. Cherylmarie1 has uploaded 5 photos to Flickr.
