Polar bear bodies are long and tapered—from their huge round posteriors to pointed, Roman noses. Their necks are also very long, which is helpful when they swim and when they thrust their heads into holes to catch prey.
Senses. A polar bear's sense of smell is very keen, and so is its eyesight andhearing. Heightened senses help bears survive in arctic conditions.
Teeth. A polar bear's cheek teeth are sharp so they can shear off chunks of meat. Their canine teeth are long, sharp, and widely spaced so they can seize and hold prey.
