The gestation period (time of pregnancy) for a bear is 180-270 days.
It will feed a polar bear for 16 years
a male polar bear and a female polar bear mate and after 9 to 10 weeks of pregnancy the female gives birth to a cub. The birth is very graphic.
Polar bears claws can grow as long as 7to8 inches and longer depending on the size of the bear.
yes
They can grow a bit taller at the shoulder and outweigh the Polar bear by 500 pounds, but the Polar bears grow longer (Polar bears up to 11 feet long, Grizzlies only up to 7 feet long!)
they are 6 inches
A polar bear can only hold its breath underwater for a little more than a minute.
Firstly, we must look at the grizzly bear. The grizzly is an inland race of the brown bear, and is smaller than the polar bear on average. However, other brown bear races such as the Kodiak bear, are just as large or larger than polar bears.The Polar bear is the longest (up to 11 feet) but the Grizzly can outweigh them by 500 pounds and grow about 3 - 4 inches taller at the shoulder. So I would say the Polar bear.
Polar bears mate and carry out a pregnancy. A mother will usually give birth to two cubs at a time.
