Hairs and bumps on the soles of their feet provide traction, while webbing between their toes allows for effective swimming strokes. Polar bears are also equipped with strong noses. They use their powerful sense of smell when hunting for seals, their main source of food.
Why do polar bears have hairy feet?
Polar bears have thick fur and black skin, which absorbs the heat from the sun. Under the skin is a layer of insulating fat. The feet have hairy soles that protect and insulate as well as ease movement across ice. … Strong, sharp claws help the polar bear gain traction, dig through ice, and kill prey.
Why do polar bears have fur on their bodies?
Polar bears have white fur so that they can camouflage into their environment. Their coat is so well camouflaged in Arctic environments that it can sometimes pass as a snow drift. Interestingly, the polar bear’s coat has no white pigment; in fact, a polar bear’s skin is black and its hairs are hollow.
Why do polar bears have stinky feet?
A new study says polar bears’ feet leave a scent behind in their footprints, which helps suitable mates find each other. The report, published in this month’s Journal of Zoology, says polar bears have enlarged sweat glands in the pads of their feet.
Why do bears have fur and sharp hooves?
The broad feet have hairy soles to protect and insulate as well as to facilitate movement across ice, as does the uneven skin on the soles of the feet, which helps to prevent slipping. Strong, sharp claws are also important for gaining traction, for digging through ice, and for killing prey.
Do polar bears have hair on their feet?
Feet are five-toed paws. … The sole of a polar bear’s foot has thick, black pads covered with small, soft papillae (dermal bumps). The papillae create friction between the foot and ice to prevent slipping. Long hairs growing between pads and toes also help prevent slipping.
How did polar bears turn white?
Polar bear hair shafts are actually hollow, which allows the fur to reflect back the light of the sun. Much like ice, this reflection is what allows these bears to appear white or even yellow at times. … In a warmer environment (like in a zoo), algae can actually grow inside these tiny hollow hairs.
How do polar bears have white fur?
The hair of a polar bear looks white because the air spaces in each hair scatter light of all colors. The color white becomes visible to our eyes when an object reflects back all of the visible wavelengths of light, rather than absorbing some of the wavelengths.
Why do polar bears have white fur but black skin?
The outer layer of hair is clear – and a polar bear’s skin is 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.
What do polar bears smell like?
The smell of your clean, non-perfumed, windblown hair when you come back inside is the closest I can come to describing the way a polar bear smells, believe it or not. … But in general, a polar bear should smell pure as the driven snow in which it lives.
Do polar bears have sweat glands?
Polar bears have the largest range size of any bear. The researchers also examined the feet of polar bears and found prominent sweat glands within the paws of two females. Other mammals are known to use similar sweat glands to communicate information about their territory and sexual or reproductive status.
How do polar bears mark their territory?
Polar bears live largely solitary lives camouflaged on the snowy arctic tundra, one of the coldest places on Earth. This barren environment lacks the trees and rocks that solitary bears in more temperate environments typically use to mark their territory with urine and body scents.
