The female Polar Bear when pregnant will enter a den to have cubs, and stay there until they are born.
On cold days they may dig a hole, curl up and even cover their nose with a paw. On warm days, they pant, may sleep anywhere in almost any position, and may be sprawled out with unfurred foot pads waving in the air, looking more like a jellyfish than the ultimate arctic carnivore. Also, in the dark winter, they may burrow into the snow to help keep warm. In the summer, they may burrow into the earth to get away from the sun and keep cool. Sometimes they'll hide from the wind behind an ice wall or something similar
No, they build dens.
by digging holes
Yes
there fur and dens.
Polar bears live in dens. The dens can get up to 98 degrees Fahrenheit (they are made of snow).
up to 4 weeks
Polar bears dig dens to protect themselves from cold winds.
The hibernating polar bears will soon emerge from their dens.
Polar bears cubs are born in something you call dens!!!!!!!!!!!!!!!
They dig up to 4-16 inches deep, it depends really.
They have not adapted. They have a particular habitat, the Arctic ice, and a particular prey, seals, that can only be caught in their dens under the ice. The ice is melting earlier and earlier every summer, so polar bears have a shortened feeding time during winter to build up their body fat to last through the summer. Weakened female bears don't produce cubs.
the usually don't build them. they tend to sleep in dens and caves sometimes even big enough trees.
