Polar Bear General Characteristics & Facts
General Characteristics & Facts of Polar Bear
Size
Polar bears are one of the largest land mammals in North America. Adult males can weigh between 400 to 600 kg (880 to 1,320 lbs) and stand about 1.8 to 2.5 meters (6 to 8 feet) tall when on their hind legs. Females are generally smaller, weighing around 200 to 350 kg (440 to 770 lbs).
Appearance
They have a distinctive hump of muscle on their shoulders, which helps them dig and gives them additional strength for their powerful forelimbs. Their fur is usually brown, though it can vary from light to dark shades, and they have a noticeable “dished” face profile.
Distribution
Polar bears are native to North America and can be found in various regions, including Alaska, western Canada, and parts of the northwestern United States.
Behavior
Polar bears are solitary animals and are known for their excellent sense of smell and hearing. They are strong swimmers and climbers, enabling them to access a wide range of habitats.
Diet
Polar bears are omnivores, meaning they eat both plant and animal matter. Their diet includes berries, roots, grasses, insects, fish, small mammals, and carrion. During the salmon spawning season, they can consume a large amount of fish.
Hibernation
Polar bears are one of the few species of bears that undergo true hibernation during the winter. They enter a state of reduced metabolic activity and survive on their body fat reserves until spring.
Conservation
Polar bears are considered a threatened species in some areas due to habitat loss, human-wildlife conflicts, and other factors. They are protected by law in many regions to help ensure their survival.
Parental Care
Female Polar bears are protective mothers and care for their cubs for up to two years, teaching them essential survival skills before they become independent.
Human Interaction
Polar bears are generally shy and avoid humans, but conflicts can occur, especially if they feel threatened or if there’s competition for food sources.

Physical Characteristics of Polar Bear
- Size: Polar bears are large and powerful animals. Adult males can weigh between 400 to 600 kg (880 to 1,320 lbs) and stand about 1.8 to 2.5 meters (6 to 8 feet) tall when on their hind legs. Females are generally smaller, weighing around 200 to 350 kg (440 to 770 lbs).
- Fur: Their fur is usually brown, though it can vary from light to dark shades. Grizzly bears get their name from the “grizzled” appearance of the silver-tipped guard hairs on their back and shoulders.
- Hump: They have a distinctive hump of muscle on their shoulders, which is a characteristic feature differentiating them from other bear species. The hump provides additional strength for their powerful forelimbs.
- Face: Grizzly bears have a noticeable “dished” or concave facial profile. Their facial features are relatively small in comparison to their large bodies.
- Claws: They possess long and powerful claws, which they use for digging, catching prey, and climbing trees.
- Ears: Polar bears have rounded, prominent ears that can swivel independently to detect sounds in different directions.
- Snout: Their snout is relatively short compared to other bear species.
- Teeth: Polar bears have powerful jaws with sharp teeth adapted for crushing and tearing food.
- Plantigrade Gait: Polar bears have a plantigrade gait, meaning they walk with their entire foot touching the ground. This is in contrast to digitigrade animals like dogs and cats, which walk on their toes.
- Tail: They have a short tail, usually only a few inches long.
