Polar Bears

The polar bear is a large specimen that weighs on average 900 pounds and can be up to 8.5 ft tall. It's covered in beautiful white fur that keeps it warm in its arctic climate. They have four legs equiped with four paws at the end of them, which allow the bear to walk. On the bottom of each paw are soft pads that give the bear cushion for walking, on the end of these paws are sharp claws. and a tail attached to its tail bone. The polar bear has a large snout that allows it to smell and fairly sophisticated black eyes that allow the bear to see, along with a set of ears on top of its head.

Although many people think that bears are part of the cat family, bears are in the canine family. They are caniforms, or doglike carnivorans, with the pinnipeds being their closest living relatives.

The definition of tundra is a big sheet of ice that covers over 5million acerrs

they have external fertilization ,

PS i learned it in science :P zz

this is all wrong...it does NOT use exernal fertilization...external fertilazation is for fish and stuf,but internal is for humans and mamals.

The particular color of a southern bear is either white or light brown,

because it is the truth. :')

Polar Bears are expert hunters. They usually hunt in areas that interface between ice and water. They rarely hunt in open water. They use a technique called "Still Hunting". They use their excellent sense of smell to locate a seal breathing hole and wait for the seal to appear. When the Seal comes out to breathe, the bear smells its breath, reaches into the hole with its front paws and drags it out of the water. They kill the seal by biting its head. They often raid the birth lairs of female seals and prey on the seal pups. They are extremely powerful and can even kill an adult walrus.

The polar bear skin is black. The hairs are often called clear or transparent but are not truly transparent. They are also not white. They look white due to reflection. The hair of the fur contains keratin but no real pigment colors. Keratin is almost clear, but is off-white, the same as your fingernails, which are also composed of keratin. Viewed side-on, the polar bears' hairs appear colorless; viewed lengthwise (as if one were looking down a tube) the hairs no longer appear transparent.

Well polar bears keep warm by there fur.It is so thick that they can go in the icy water so that's how polar bears keep warm

Their paws can be 8 inches wide and their claws can be 6 inches long!

The habitat of the polar bear is the Arctic. Considered a marine mammal, it is found mostly on sea ice or frozen circumpolar coastal regions. Occasionally up to 120 miles inland

The polar bear is found in the Arctic Circle and the nearby islands. They can be found in good numbers in Alaska, Norway, Denmark, Russia and Canada. There are smaller populations in the surrounding regions near the Arctic pole. They prefer the Cold Icy areas of the Arctic and thrive in areas where the human intervention is minimal. They are found in good numbers in areas where their primary prey, the Seals mate and nest.

The polar bear has two adaptive features designed to keep it warm;

- Fur

- Fur in between it's toes and on the pads of it's feet.

The animals that have blubber are: whales, seals, sea lions, elephant seals, walruses and 40% of Americans most aquatic and/or semi-aquatic animals.

Don't forget penguins, a lot of seabird chicks have a heavy blubber layer which is lost before fledging.

Most animals with blubber live in freezing and/or arctic climates.

They eat seal and carcasses. The Polar Bear's favorite food is the ringed seal, although they also hunt Bearded, Harp and hooded Seals. Polar Bears gather in groups when the food is scarce. When the food is scarce the Polar Bear also eats the carcasses of walruses, or whales such as the Narwhal, Beluga and bow head whales. Baby Polar Bears nurse and are fed with their mother's milk. They also eat small portions of what their mother kills.

Polar bears get their water from the chemical reaction that breaks down fat. This is why a polar bears diet is high in fat but low in protein. For example, when they hunt seals, polar bears will eat the blubber, but leave the rest behind for scavengers.

Polar bears are remarkably adapted to withstand the incredible cold (-70 below zero sometimes) of the Arctic north pole.

But when temperatures do get extremely cold, like -70 below zero, during a raging blizzard, polar bears will actually scrape a snow wall for protection against the wind. Polar bears will also dig a den in the snow to deliver their babies.

But most of the time in the winter, when temperatures just hit

-30 below zero, polar bears sleep out in the open on the snow. When the pack ice forms in deep winter, the polar bears go out on the ice to hunt seals. Polar bears think nothing of diving in and out of the frozen slushy water when traveling from ice floe to ice floe; and polar bears are great swimmers sometimes paddling miles out to sea away from any land or ice berg.

Yes, for such a large animal the cubs are born very little. After a gestation period of anywhere from 195 days to 265 days. This includes a period for delayed implantation. The female Polar Bear will snuggle into the winter den she has built. Which is about the size of a telephone booth, with a couple of narrow alcoves. But this small space can keep her and the cubs, about 40 degrees warmer than it is outside. She then gives birth to anywhere from 1 to 4 cubs. But, on average it is a pair. The birthing occurs between late November, and early January. The cubs are born blind, almost hairless, and weigh about 1.3 pounds, about the size of a small rat. They depend on her for everything. Her milk is 35 percent fat, and considered the richest of any of the other bear species. This will help the tiny cubs grow fast and strong. By the time April arrives they can weigh more than 20 pounds, and be ready for the den to be opened and the sun to shine in. It will take on average, about two years before the cubs are ready to live on their own. For more details see sites listed below.

Whatever scavengers that are around, Arctic foxes, maybe other bears.

It is the mother polar bear that teaches her cubs (usually two cubs) by example. Cubs often hamper their mother's hunting, but eventually the cubs become able to exist on their own. A mother polar bear will try to avoid meeting an adult male polar bear, as there is a danger the male may kill and eat her cubs.

Feces, poo-poo, dung, crap, crud, droppings, night soil,etc.

Polar bears are mammals and give live birth.

Yes. Like most bears, Polar bears are good at swiming. This helps them catch fish and also survive if the ice cracks and drifts away.

Polar Bear hair is a clear hollow tube and there skin is actally white

Polar bears live only at the North Pole, or, more correctly, in the Arctic.
