Why do polar bears have strong front legs?
The partial webbing between their toes, polar bears are able to use their front feet much like paddles to propel them rapidly through the water. The hind feet are slightly smaller. On both the front and hind feet, the bottoms are covered with dense fur, which affords better traction when moving on ice.
Why do polar bears have large body?
Large Size. As Dr. Andrew Derocher explains in his recently published book, Polar Bears, A Complete Guide to Their Biology and Behavior, this is because large animals have a higher volume to surface-area ratio, so they lose less heat through their skin. This is an adaptation common to many species in cold habitats.
Why are polar bears strong swimmers?
Polar bears are great swimmers, thanks to their hollow, water-repellant fur, buoyant fat layer, large paws, and tapered body shape. Polar bears are specialized to hunt seals, so they must venture out onto the sea ice to survive. Most of a polar bear’s time is spent, if not always in the water, then on or around it.
Why does a polar bear have long legs?
Many believe that the small size of the Polar Bear’s ears and tail don’t match the rest of their body! Even though the Polar Bear has very short legs, they have long feet. This too seems somewhat out of place. It is believed this design of their feet though helps them to evenly distribute their weight as they move around.
Why does a polar bear have a strong neck?
The large body size of a bear prevents the heat loss—thereby making it warm even in frigid arctic weather. According to The American Society of Mammalogists the polar bear’s neck muscles are extremely strong and powerfully developed. This can be evident from the fact that ice bears can easily pull a 600-pound seal with their neck.
What do polar bears do when the ice is thin?
When the ice is very thin, the bears extend their legs far apart and lower their bodies to distribute their weight. Polar bear paws aren’t designed to help just on land. When swimming, the bear’s forepaws act like large paddles and its hind paws serve as rudders.
Why do polar bears have pads on their feet?
Polar Bear Teeth To help protect their feet, there are pads on the bottom of them. They are designed to give them plenty of traction for walking on the slippery ice. The claws are much shorter than those of other species of bears. They are designed to allow the Polar Bear a way to easily dig and to scoop the ice.

Why do polar bears have strong paws?
Their feet are heavily furred for warmth and their pads are rough for added traction on the ice. Their feet are also quite large, often about 12 inches wide, to match their weight and to spread that weight out over deep snow and thin ice to avoid falling through.
Why do polar bears have thick layer of fat?
Almost every aspect of the polar bears design is engineered for warmth. Their bodies are designed to be lined with a cozy layer of fat, which can be up to 3.4 inches thick. This fat not only helps polar bears keep warm, but acts as an energy store for slow hunting periods.
Why is Polar bear skin black?
Polar bears evolved to have black skin, as the colour is the best for absorbing energy from the sun. The clear fur allows this sunlight to get to the skin – but it still looks white, so that the bear can blend in with its environment of ice and snow.
