What are the sizes of polar bears?
The polar bear is the largest carnivore on the earth. Adult males weigh between 350 to 680 kilograms (770 to 1500 pounds). They can measure between 2.4 to 3 meters in length (7.9 to 9.8 feet). Females are comparatively smaller and weigh around 150 to 250 kilograms (330 to 550 pounds) and measure 1.8 to 2.4 meters (5.9 to 7.9 feet) in length. However, when the female is pregnant, she can weigh as high as 500 kilograms. The largest ever Polar Bear recorded by man weighed 1002 kilograms (2210 pounds). Standing on all four feet, their height at shoulder is around 130 to 160 cms (4 to 5.5 feet) and while standing they can be as much as 10 feet or more in height.
If polar bears become extinct how will it affect our food chain?
They won't and it would not affect our food chain. It would be a terrible loss to the planet though. Fortunately, they are not endangered and their numbers are still growing. They now number well over 20,000.
What does a polar bear's mouth look like?
It looks like any other bear's mouth, except that it has white fur.
Are there different kinds of polar bears?
Polar Bears require a great area to support themselves therefore they travel far and spread their species throughout the north. There is only one species. Polar Bears require a great area to support themselves therefore they travel far and spread their species throughout the north. There is only one species.
Why are polar bears dying quickly?
Most people say globle warming, at the same time their are periods on earth when it's cold, and hot. They can be in long periods of time or short. This one is planed to go for a century. But we can not calculate it.
What needs to be done to polar bears?
The only way is to try and slow and then reverse global warming.
We are trying to lessen the greenhouse gas emissions so that the risk of global warming will be less and that will help stop the melting of the polar ice caps which will save some of the polar bears habitats.
Hunters have to stop killing polar bears.
Isn't it the greediness of the professional fishermen that causes the misery of polar bears? With all of their high technological equipment they give fish no chance to survive! Whole food chain is broken! Seals have nothing to eat, they are dying of hunger and disease, as their immune system weakens!
Polar bears have neither fish nor seals to eat!
We humans do have responsibility to save the life on the planet Earth!
recycle and save energy
We can help by wisely using resources, not polluting anything on purpose, make constant notes to walk to nearest stores or a friend's house. Riding to school in a carpool with your friend, not riding a taxi, but riding a bus.
Well you can STOP polluting and think green.
Actually, the only way to help polar bears is to reverse climate change, as their habitat (sea ice) is shrinking rapidly. The whole world has to move to renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel) so we can stop emitting greenhouse gases.
you can save polar bear lives by reducing greenhouse gas emission
Why don't polar bears live in the southern hemisphere?
Because they evolved from brown bears, and this species is found only in the northern hemisphere.
Also polar bears are primarily aquatic feeders - feeding on and around ice floes - and the South Pole is a LONG ways from any open water or ice pack. Antarctica is HUGE. In theory polar bears might survive in the seas around Antarctica, but it's not their native habitat and there is much less ice pack than in the Arctic because most of the ice is deposited on the land mass of Antarctica.
It would be really hard, but just check the eye color most albinos have a odd eye color like red.
Where do you find most of the polar bears?
You would find a polar bear where the ocean is covered with ice.
So that means you would fid a polar bear in Alaska, the Arctic regoion
Why does not a polar bear eat fruit and vegetables?
Polar bears are primarily carnivores, and though vegetation does grow in the Arctic region where it lives, it's not large nor significant enough to sustain a polar bear enough. Vegetation in the Arctic is sparce and very small and often only enough that a tough herbivore like a caribou, lemming or muskox can sustain itself on, but certainly not a large animal like a polar bear.
people eat polar bears
Humans do so.
Polar bears are top of their food chain. VERY rarely a pack of wolves may attack them
Answer:
Polar Bears (Ursus maritimus, the "sea bear") are the top predator in their ecosystem. Larger male polar bears eat polar bear cubs. Humans hunt and kill the adults. Aside: In case the question was really after what animals did polar bears descend from (predaters), scientists believe that evolved about 200,000 years ago from brown bear ancestors.
Humans, killer whales (orcas), and other polar bears are the only known Earth animals that prey upon polar bears.
No animal does.
No animal does.
NO THEY DON'T.
Think of it this way it is not like your mom would kill you.
Actually, yes they do. Boar bears (male bears) have been known to actively go about and kill young cubs if they are not watched by their mother or if the mother has been scared off or beaten so badly that she can no longer defend them.
What adaptations do polar bears have to keep warm?
By having Thick fur and and a lot of fat. this helps it keep warm and fat for the freezinf cold environment
it has thick fatty fur to help stay warm. their padded feet hhelp them grip to the ice
How do you become a polar bear?
It is impossible to become a polar bear unless you are born a polar bear. But you can become like a polar bear by imitating some of its distinct characteristics. If you want to look like a polar bear, you will have to make a costume of white fir, wear big teeth, and have two little ears and a little tail. You will then want to act like a polar bear, swim like a polar bear, and eat like a polar bear. But you will never mate with a polar bear or make little baby polar bears.
What is the mobility of a polar bear?
polar bears do most of their traveling by walking,which they do on all four legs
Polar bears do most of their traveling by walking, which they do on all four legs. Like other bears, they can run much faster than humans, reaching speeds of up to 35 miles per hour. Polar bears are also very good swimmers, even in the near freezing waters of the Arctic Ocean.
No. Polar bears live around the Arctic region. Australia has no bears - the koala is not even a bear although it is often referred to as one..
Do polar bears change hair and skin color in the summer and the winter?
Nature decided that they do not need camouflage in summer so their fur, which is really transparent, appears to stay white all year round.
Where are the habitats of the polar bear?
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.
Is there mutualism between a polar bear and another animal?
Yes. They are carnivores. Seals are the preferred diet/prey for Polar Bears. Most of its diet consists of ringed or bearded seals. They are also known to hunt and kill adult Walruses and even Beluga Whales. Mature/Adult bears tend to eat only the calorie rich skin and blubber of the seal, whereas youngsters consume the meat as well. They have been known to even raid bird nests and feed on chicks and eggs.
How far away can a polar bear smell a seal under the ice?
Reports say that a polar bear can smell a seal over a mile away. That's on top of the ice, not under it. Bears can't smell seals that are under water.
