"Need to gain a little weight
The Polar Bear needs extra weight for pregnancy.
Female polar bears must gain up to 440 pounds when pregnant in order to have a successful pregnancy.
They start mating when they are about 4 years old. The mating process occurs in the spring, which gives a pregnant polar bear enough time to gain the extra blubber and weight needed to keep her warm during the harsh winter.
If the mother does not gain enough weight, her pregnancy will not go well.
The male polar bear helps the female hunt for seal pups, which are an excellent source of fat and protein.
Once the cubs are born, they will remain with their mother for a little over two and a half years before they leave the den.",
"Air conditioning.
The polar bear is the world’s largest land carnivore.
It might be surprising that these animals are in danger, but climate change is causing the disappearance of sea ice, from which polar bears hunt their prey.
If current heating does not change polar bears could be extinct within one hundred years.",
"How's the weather up there?
Male Polar bears are up to 11 ft long from nose to tail. Polar bears are the biggest bears in the world.
When standing on all four paws, a polar bear is typically just over 5 ft in height.
However, when they stand upright the polar bear is usually 8 ft, but can grow as much as 11.",
"Big Bears!
Polar bears can weigh up to 1500 pounds!
Polar bears have adapted to the cold environment they live in. Their bodies are covered in a thick layer of blubber that helps them stay warm and retain their body heat in the frozen temperatures.
This layer of blubber is covered in thick, clean fur that appears to be snow white in color.
Most experts agree that polar bears are the tallest bears.",
"Sea Bear.
The polar bear is known by the species name Ursus Martimus, which is Greek for sea bear.
Polar bears are most often found in the Arctic region.
They spend their time hunting seals, lounging on the ice, and swimming.
As weather warms, they follow the ice north until wintertime returns since they thrive in the cold weather.
How much access they have to ice and hunting seals will dictate how far they must migrate north.
Some polar bears have a very small migration while others may travel a few hundred miles to be able to feed regularly.",
"40,000 and counting.
There are as many as 40,000 polar bears in the world.
Polar bears live in groups that are divided up by their location.
There are six main groups of polar bears in the world. These polar bears do not leave their group, so every bear that has been with a group has always been there.
The main places polar bears live are along the coasts of the northern continents of North America and Europe and off the coasts of Russia and Greenland.",
"Hide and seek.
A polar bear's fur is so effective at trapping heat, it cannot be seen using infra-red vision.",
"Not as it appears.
Despite appearances, polar bears' fur is not white.
They have a thick woolly undercoat of fur close to their skin, and an outer coat of long guard hairs that stick together when wet and act like a wet suit to keep them dry.
Even though they look white, their hair is made of clear, hollow tubes filled with air, a bit like plastic drinking straws.
Under their fur, polar bears' skin is black. ",
"Natural born killers.
Polar Bears are considered the best hunters of any bear.",
"Follow the nose.
Polar bears are often referred to as ‘noses with legs’. Their sense of smell is so powerful that they can smell a seal on the ice 20 miles away.
They can sniff out a seal’s den even if it has been covered with snow, and they can locate a seal’s air hole in the ice up to a mile away.",
"Keep the extra fat.
Polar bears have a thick layer of fat which is 2 to 4 inches thick.
This blubber helps insulate them against the freezing cold winds and icy water, and acts as a nutritional reserve when food is scarce. It also helps them float.
They are the tallest bear at 10 feet long, and weigh about 1,700 pounds.",
"Quiet as a mouse.
Polar bears are as quiet as cat burglars.
They have stiff fur on the soles of their feet which allows them to sneak up on sleeping seals without being heard.
It also helps them walk across the slippery ice without falling over.",
"Just a little exercise.
Polar bears are champion long-distance swimmers.
They have broad front feet for paddling, and large back feet which act as rudders and help them to steer in the right direction.
They can swim distances of 40 miles in icy water before they need to rest.",
"Can I have a glass of polar bear milk?
Milk from a polar bear mother is the richest of any bear species. A polar bear mum’s milk is around 35% fat, which helps her cubs grow quickly.
By 3 months of age, a polar bear cub weighs more than 20 pounds and is ready to move outside the den. They are not left on their own until they are 2 years old.",
"Light sleeper.
Polar bears do not hibernate. Whilst their body functions slow down, and they retire to their dens and sleep, researchers call this ‘winter sleep’ rather than hibernation.
They are easily awaken from winter sleep, and mothers continue nursing their young cubs during this time.",
"Its too hot in here.
In summer, a polar bear’s insulating coat can be too warm. The 2 to 4 inch layer of fat that keeps them warm in winter can also overheat them during the summer months.
This may explain why they walk across the ice at a leisurely pace most of the time rather than run. They also take to the icy-cold water regularly during summer in an effort to cool off.",
"Faster than it looks.
Even with its enormous size and weight, the polar bear can outrun the reindeer.",
"Super nose.
Polar bears' long heads makes room for their long noses, which gives them an acute sense of smell.
It is said a polar bear can smell a seal from 3 miles away.
So keen is its smell that it can smell out a seal's lair hidden beneath the ice.
Even though the lairs may be covered by 4 feet of ice the polar bear's strong paws can smash through the ice until it caves in.",
"Small for their age.
Newborn polar bears are smaller than human babies.
A newborn polar bear weighs only one-third as much as a newborn human - about 2 pounds (1 kg).
Yet, when fully grown, polar bears reach weights of up to 1,800 pounds (800 kg).",
