Polar Bears

The polar bear has no actually prey but some polar bears have been known to have been killed bye killer whales and Greenland sharks. Sometimes there has been the polar bear preying on them!!!

Small cubs are preyed on by adult polar bears. Humans are pretty much the only other real issue. They can and do hunt polar bears. This is the reason their population went down many years ago to dangerously low levels. The limits on hunting allowed them to regain population.

• 1. They need the food.
• 2. They need to eat the fat from the seals so they can survive and not freeze.
• 3. They like to eat the fat off the seals.
• 4. Polar bears need about 4.4lbs of fat per day to survive. The fat gives them enough energy to be able to withstand subzero temperatures. An average weight of a ringed seal is around 121 lbs. If a polar bear catches one and eats the whole thing it will have about 8 days of energy. They will not need to eat or hunt in those 8 days.
• 5. Polar bears also like to eat seals because in the spring the seals have their pups. That means that they can teach their cubs how to hunt the seals without endangering the cubs.
• 6. A polar bear can catch seals really easy.
• 7. They're carnivores.

Environmental change is affecting the polar bears because of the melting of the polar ice caps and the increasing temperatures. The melting of the ice caps will give the polar bears a lack of habitat and also no place to hunt for pray. And they are evolved to the cold weather so therefore Global warming will cause them to become extinct ! .. Poor Polar bears .

We can reduce this chance by walking or cycling instead of driving a personal car. and if it is to far to walk or cycle take public transport. we can also do this by using renewable energy sources such as solar, tidal and wind power. And not use fossil fuels like gas, oil, petrol etc

There is no tangible evidence of the ice cap melting any more than normal. In the Arctic summer it recedes, then refreezes in winter. The polar bears are not becoming extinct, their population is actually increasing in some populations.

No. If it is put in a zoo it requires special care.

Mostly, they fish. Not mush else to add to this question.

They mainly feed on ringed and bearded seals. Also, depending on where they are located they may scavenge on various whale carcases.

It would be highly unusual to see a bear in the wild in the state of Illinois. However, the American black bear in the nearby Appalachians and Ozarks is occasionally known to leave its preferred forest environment in search of food.

Cubs stay with their mothers for two to three years.
For a couple years at the most.

Polar Bears are becoming endangered so, Polar Bears can be spotted at the local zoo or in the natural land in the icebergs of Alaska and Canada. Their habitat is melting so there have become less and less of them.

I couldn't find the answer anywhere Spectacled bears are NOT extinct. They are Threatened and need to be protected. For more information with photos and more, go to: http://www.squidoo.com/spectacled-bears

Animals, just like us humans, tend to use one hand over the other. I have done some research and have found that they tend to be Left handed, or Left pawed. lol I am left handed, what a coincidence!

Yes, a Grizzly Bear does experience a full molting of their coat/hair annually. The time of year the molt takes place depends to a large degree on what sex the bear is, the age of the bear, and the region or area it inhabits. So to describe a Grizzly Bear by it's color is not reliable considering that the color will, and can change for several months while the bear is molting and the sun can bleach the hair in between the annual molting. For more details, please sites listed below.

Polars bears homes are melting mainly because of global warming. The toxic wastes that cars and factories make, makes an attraction to the sun which slowly heats up the earth. This is bad because glaciers cool the atmosphere and if there are no glaciers, the planet will slowly heat up to a degree that nothing would be able to live in (including humans).

Its hard to say - not many people know. Adult polar bears get up to 10feet (3 metres) tall if that helps
Each polar bear litter has 2 cubs and sometimes even 3 cubs. Cubs weigh around 10 to 15 kilograms (22 to 33 pounds) at birth. Size wise, the cubs are only a feet or so in length. They are totally helpless/defenseless at birth and depend entirely on their mother for food and protection. Cubs stay with the mother for around 2 to 3 years of their life and then go away.

There should be no reason to capture them for zoos. There are plenty in zoos that can be used to breed specimens for zoos. Let the wild ones roam free!

by far polar bear because the live in much colder weather then sea otter

Polar Bears are very vulnerable to climate change and human hunting. Due to their sheer size, they have no natural predators except themselves. Large males have been known to kill off younger/smaller bears to cut out on competition. Man has been hunting these giant carnivores for centuries for its skin and fur. As of now, approximately 20000 to 25000 animals exist in the Arctic wilderness. Their numbers are steadily declining due to habitat loss and hunting. Oil and Gas exploration in the Arctic too is a significant cause for the decline in Polar Bear numbers. Due to human activity and global warming, the ice caps are melting. So, the effective land that the bears have for hunting is coming down. Pollution too is killing off prey species. So, everything put together is endangering the species.

Well a bear bear, as opposed to a, say, teddy bear, has many more individual things inside of it. For instance, the inside of a bear bear contains organs while a common teddy bear usually only contains a single type of stuffing.

Some stuffing a teddy bear would have inside of itself is wool wool. (No joke, The actual name is [wool]x2.

The most common stuff inside of a teddy bear is polyester. It is Inexpensive, easy to use, and available everywhere. Other very uncommon stuffings are wool, corn, and bamboo. Some posable bears contain glass or plastic pellets. It could also contain Metal electronic devices that make sounds or magnets.

The inside of a bear bear could be very similar to what is inside of you right now. Bear bears could contain any one of those objects that could be found inside of a teddy bear. In addition, they contain a skeletal system. Their skeletal system contains about 360+ bones. This includes major bones such as the cranium and bones that you have probably never heard of before such as the ol ecranon process. A bear bear also has a very strong muscular system that aids their skeletal system inside of them. Other major things inside of a bear bear are it's organs.

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.

the averrage is about 2km but some beer can more 5km

They spend most of their time eating the seals and especially the seal fat. They prey on both the bearded and ringed seals.

Polar Bear do not typically eat fish. Their diet consists mainly of seals, but they will resort to eating fish if no seals are available. Polar bears need to consume nearly four and a half pounds of fat daily to survive.

The female polar bear lives with her cubs for more than two years.

By that time they are weaned and have learned how to hunt and look after themselves.

The male polar bear does not live with them. In fact, male polar bears have been known to kill cubs.
