What do polar bear cubs eat?

polar bear cubs get milk from their mom.
Polar bear cubs are nursed by their mother for 2-2.5 years. This means that their diet is made up of milk.

When they are weaned, their diet becomes very similar to adult polar bears - they eat mainly seals. Sub-adults may be forced to feed on the left-over carcasses of older bears if they are to young to kill their own.

How does a polar bear meet its needs for food water and shelter in its habitat?

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.

Are polar bears born with fur?

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.

What happens after polar bears die?

What does a polar bear mother teach her cubs?

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.

Why are polar bears losing their habitat?

Global Warming melting the Ice caps that they feed on is the current myth. Reality is that hunting is a problem for these creatures. Man is the only real issue for them.

Global warming is merely a current mantra. The current cooling will do nothing for them either. If the past warming trend was so bad for them, why have their numbers gone up so fast in the past decades? Hunting of them is a real issue. Shooting one takes them out of the pool. The idea that a decade ago the heat is somehow affecting them now is merely foolishness. The current growth of ice is equally no reason to exclaim joy for them. They are still be hunted and their numbers, while having impressively increased in the recent decades, could be far higher. wat ever that's just a load of rubish
