What features does a polar bear have to survive in the cold?
Polar bears live in one of the planet’s coldest environments and depend on a thick coat of insulated fur, which covers a warming layer of fat. Fur even grows on the bottom of their paws, which protects against cold surfaces and provides a good grip on ice.
How can polar bears survive in the cold water?
Two coats of fur and a thick layer of blubber help insulate the polar bear’s body from the cold, keeping its temperature at an even 37° C (98.6° F). In addition, polar bears’ paws are especially adapted for walking on the ice and swimming in the sea.
Which of the following features help polar bear adapt in extreme cold condition?
The correct option for this question will be white fur, flat feet, fat under the skin which helps the polar bear to survive in extreme cold.
What polar bears survive?

How do polar bears survive in the cold Class 7?
2) Polar bear has two thick layers of fur on its body: This fur protects the polar bear from extreme cold by preventing the loss of heat from its body. Thus, the two thick layers of fur keep the polar bear warm in extremely cold climate. The polar bear has also fur on its feet and toes.
What are the features of polar bears?
- comparatively slim body with long neck.
- narrow head with small eyes and outer ears.
- paddle-like paws with webbed toes.
- short tail (7 to 13 centimetres)
- five short, non-retractable claws.
- body covered with hair, with the exception of the lips, the nose and part of the soles of the feet.
How cold can polar bears withstand?
Thanks to special adaptations, such as a thick layer of blubber, two layers of fur, compact ears, and a small tail, polar bears can withstand temperatures as low as -50° Fahrenheit. Polar bears use snow like a towel. First they shake off the water; then they roll in the snow to dry off.
Which of the following adaptations keeps the polar bear warm?
Thermoregulation. Body temperature, which is normally 37°C (98.6°F), is maintained through a thick layer of fur, a tough hide, and an insulating fat layer (up to 11 cm or 4.5 in. thick). This excellent insulation keeps a polar bear warm even when air temperatures drop to -37°C (-34°F).
Which of the following is not an adaptation feature in polar bear?
Answer: The Longtail is not an adaptive feature of the polar bear.
Which of the following is not an adaptive feature in a polar bear?
Like: they have white fur that helps in hide in plane sight, strong sense of smell helps in hunting of seals (main source of food), long curved and sharp claws helps in swimming but long tail is not a adaptive feature in polar bear but presence of fur on the tail help to prevent it from freezing.
Do polar bears feel cold?
You would think that in their icy, arctic environment, polar bears spend most of their time shivering with cold! … A polar bear’s body temperature runs around 98.6º Fahrenheit, typical for most mammals, but their adaptation to cold weather means they have an unfortunate propensity to overheat.
Can polar bears live in warmer climates?
“Even in Alaska and northern Canada, the temperature can get up to the 80s in the summer. So they’re adapted to not only the really cold environment and icy cold water, but they do OK in warmer summer conditions.”
How do polar bears camouflage?
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.
