What does a polar bear cub look like?
Polar bears are tiny and helpless at birth
When born, cubs are blind, toothless and covered in a sparse layer of soft, short fur. Newborn cubs are only about 25 centimeters long and weigh around one kilogram, but they grow rapidly thanks to their mother's rich milk which is approximately 31 per cent fat.
Polar bears are the largest carnivorous land mammals on Earth. They are about seven to eight feet long, measured from the nose to the tip of their very short tail. Male polar bears are much larger than the females.
Polar bears are stocky, with a long neck, relatively small head, short, rounded ears, and a short tail. The male, which is much larger than the female, weighs 410 to 720 kg (900 to 1,600 pounds). It grows to about 1.6 metres (5.3 feet) tall at the shoulder and 2.2–2.5 metres in length.
Why are cubs born so small? Part of the answer has to do with hibernation. The mother's lowered metabolism means lower blood oxygen levels for the fetuses. Early birth gets them out breathing on their own as soon as possible.
Just like with other species of bears, the baby polar bear is called a cub. By the time a cub is six months old, it's old enough to leave its mother to venture out on its own. At this point, it would be called a subadult. Polar bears are subadults until they're old enough to mate.
Bears are probably what you think of first when it comes to cubs. From the grizzly to the giant panda, all baby bears can be referred to as cubs. Polar bears (Ursus maritimus) are normally solitary creatures, except for mothers keeping their cubs close.
Interestingly, the polar bear's coat has no white pigment; in fact, a polar bear's skin is black and its hairs are hollow. They have a thick layer of body fat, which keeps them warm while swimming, and a double-layered coat that insulates them from the cold Arctic air.
The insulating layer of fat is present beneath the skin. Long, curved, sharp claws for walking and running on ice. A thick coat of white fur acts as protection from predators because of its white color that camouflages with the surrounding snow. The thick coating of fur keeps it warm.
Common characteristics of modern bears include large bodies with stocky legs, long snouts, small rounded ears, shaggy hair, plantigrade paws with five nonretractile claws, and short tails.
At birth, polar bear cubs weigh about 454 to 680 g (16-24 oz.) and are about 30 cm (12 in.)
Who is bear King?
In the ancient epic of Ramayana, Jambavan, the divine king of bears, assists Rama in the battle against Ravana, the king of Lanka.
With the exception of opossums and kangaroos, giant panda newborns are the smallest mammal babies compared with their mother's size.
They are born blind, hairless, and deaf. Within the first month of life, their eyes open, and within 2 months, they grow teeth and fur and begin to walk. Cubs weigh around 1 pound at birth but are nursed to a weight of 20-30 pounds by the time they leave the den in March or April.
A mother bear will typically give birth to one to three cubs at a time. By the time a mother bear and her cubs are ready to emerge into spring, the cubs typically weigh around five pounds. Young bears grow very quickly and can weigh around 80 pounds by their first birthdays.
Seals are a energy-rich food source, especially for hungry polar bear mothers and their growing cubs. Polar bears can devour huge amounts of fat from seals when they are available.
Around the age of four or five the female polar bear can start having babies. They usually only have two cubs and they have these babies in a cave they've dug in a large snow drift. They stay there over winter and come out in spring with the babies. The babies are much smaller than human babies when they're born.
Behind their snow-white fur, polar bears have black skin!
Polar bear cubs are born with pink skin, but once they turn 3-4 months old and step out of their dens, their skin turns black. Proof? The black skin is most easily seen on their nose, lips, and footpads.
Mothers will give birth between November to the February and will leave their maternity dens in February. Mothers most commonly give birth to twins but can also have a litter of one or three. Polar bear cubs are born about 30 cm (11.8 in) and weigh less than 0.9 kg (2.0 lb).

Why is polar so cold?
Both the Arctic (North Pole) and the Antarctic (South Pole) are very cold because they get very little direct sunlight. The Sun is always low on the horizon, even in the middle of summer. In winter, the Sun is so far below the horizon that it doesn't come up at all for months at a time.
Polar bears feed primarily on ringed seals, but will also eat bearded seals, harp seals, hooded and harbor seals, when available. Larger prey species such as walrus, narwhal and beluga are occasionally hunted.
Average January temperatures range from about −40 to 0 °C (−40 to 32 °F), and winter temperatures can drop below −50 °C (−58 °F) over large parts of the Arctic. Average July temperatures range from about −10 to 10 °C (14 to 50 °F), with some land areas occasionally exceeding 30 °C (86 °F) in summer.

Yes! Most sources indicate that the long, coarse guard hairs, which protect the plush thick undercoat, are hollow and transparent. The thinner hairs of the undercoat are not hollow, but they, like the guard hairs, are colorless.
Their skin - and tongue - is black
Maybe dark skin helps to keep the bear warm by absorbing heat, or maybe it's just a quirk. Even polar bear tongues are dark, often ranging from blue, to purple, and sometimes black.
Meteorologists record the weather every day. The records of the weather have been preserved for the past several decades. These help us to determine the weather pattern at a place. The average weather pattern taken over a long time, say 25 years, is called the climate of the place.
To maintain an interior body temperature that allows them to survive longer and nowadays more frequent swims, the bears temporarily cool the outermost tissues of their core to form an insulating shell -- a phenomenon called regional heterothermy.
To live in an extremely cold climate, the polar bear has many adaptations, such as: (a) The layer of fat under the skin for insulation. (b) Long curved and sharp claws to walk and run on slippery ice. (c) Thick white fur.
While their tongues may be extra-big, sun bears are actually the smallest bear species. Males grow about 5 feet long and weigh up to 150 pounds—that's about half the size of an adult American black bear. These animals live in wooded areas of Southeast Asia. Strong and agile, sun bears are good at climbing trees.
Can't bear can't stand?
It's a subtle difference, but “can't stand” means you dislike the thing in question. “Can't bear” means you aren't able to handle it, but doesn't have the same value judgement.
Black bears living in Alaska that can feed extensively on salmon weigh around 30kg more. Black bears are incredibly strong, able to casually flip boulders weighing over 140kg with a single paw.
Kodiak bears are the largest bears in the world. A large male can stand over 10' tall when on his hind legs, and 5' when on all four legs. They weigh up to 1,500 pounds. Females are about 20% smaller, and 30% lighter than males.
Generally, a polar bear cub will stay with its mother for two to three years learning valuable survival skills.
The polar bear's Latin name, Ursus maritimus, means "sea bear." It's an apt name for this majestic species, which spends much of its life in, around, or on the ocean–predominantly on the sea ice. In the United States, Alaska is home to two polar bear subpopulations.

Blue whale calves are the largest animal babies in the world, clocking in at a whopping 1360kg —almost the same size as a small car.
Elephants are the largest land mammals in the world, so it's perhaps not surprising that they have the longest pregnancy of any living mammal: African elephants are pregnant for an average of 22 months, whilst for Asian elephants it's 18 to 22 months.
What is the smallest pregnancy?
The shortest known gestation is that of the Virginian opossum, about 12 days, and the longest that of the Indian elephant, about 22 months.
Hearing: They have acute hearing that is about twice as sensitive as humans and over a large frequency range as well. Bears often hear humans before we see them. Because of this, black bears will often move away before they are noticed.
Autumn: Digging a den
In most areas, pregnant polar bears dig dens deep in snow drifts on land or on the sea ice, where they will wait to give birth during the winter. In Canada, some bears build dens in frozen peat banks. Expectant mothers use these dens to rest and keep warm during the harsh Arctic winters.
They are born blind, covered with fine hair and they nurse on their mother's milk. Female bears may give birth to 1 cub to 5 cubs at a time, but 3 is the average litter size in New Jersey. Cubs grow very quickly and they weigh about 80 pounds by the time they are one year old.
If a bear cub is on your property, do not try to handle or capture it.
“A yearling bear often looks about the same size as a large Labrador retriever (80-100 pounds),” she said. Also look at the size and shape of the head. An old boar's head looks blocky and thick.
Sun bears are the smallest bear in the world, weighing between 75 and 80 pounds. A big male Borneo sun bear might be 100 pounds. A male grizzly bear, on the other hand, can easily weigh up to 600 pounds (and those that feed on salmon in Alaska can weigh considerably more).
Behind their snow-white fur, polar bears have black skin!
Polar bear cubs are born with pink skin, but once they turn 3-4 months old and step out of their dens, their skin turns black.
They are born blind, hairless, and deaf. Within the first month of life, their eyes open, and within 2 months, they grow teeth and fur and begin to walk. Cubs weigh around 1 pound at birth but are nursed to a weight of 20-30 pounds by the time they leave the den in March or April.
“If the ears seem to stick up well above the head and are close together on top of the head, that is likely a young bear. As the bear matures its head will get larger and the ears become smaller, looking and spaced wider across the top of the head.”
What is the true color of a polar bear?
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.
Polar bears are not actually white. In fact, depending on certain environmental conditions, and under varying lighting, a polar bear's coat can often appear as grey, yellow, orange and even pink.
When they're born, polar bears are both blind and toothless, making them vulnerable to predators. These tiny polar bears are entirely reliant on their mother, who feeds them milk and keeps them warm during the Arctic winter.
A polar bear's head is oblong and relatively small compared to body size. The muzzle is elongated with a "Roman-nosed" (slightly arched) snout. The nose is broad and black.
Congenital deafness (usually hereditary) has been reported in more than 100 dog breeds and is especially prevalent in the piebald-carrying breeds of Dalmatian, Dogo Argentino, Catahoula Leopard Dog, Bull Terrier, Australian Cattle Dog, English Setter, English Cocker Spaniel, Boston Terrier, and Parson Russell Terrier, ...
Males are born slightly larger than females. Polar bear cubs are born small and helpless, with their eyes closed. The fur is very fine at birth, making the cubs look hairless..
Not unlike people, bears can be empathetic, fearful, joyful, playful, social and even altruistic. They're all individuals and have unique personalities. Cubs, as well as older bears, engage in social play and have ritualistic mechanisms to meet strangers and decide if they are friendly or not.
Studies indicate that bears do see in color. Tests with black bears and polar bears indicate that bears can see color.
Yes! Most sources indicate that the long, coarse guard hairs, which protect the plush thick undercoat, are hollow and transparent. The thinner hairs of the undercoat are not hollow, but they, like the guard hairs, are colorless.
