TRIVIA: Why Dont Polar Bears eat penquins?
449496
Polar bears, IN THEIR NATURAL ENVIRONMENT, don't eat penguins because they live at opposite ends of the globe (And, hence, never encounter one another).  HOWEVER, it has been discovered (accidentally (One would hope)) that polar bears WILL eat penguins, if given the opportunity in the zoo.

No problem with this happening at the north pole....\nIf he goes east along exactly a circle with a circumference of 5 km, around the N Pole (radius about 0.8km)(this makes him start approx. 5.8 km away from the N pole), he ends up in the same place and can shoot any polar bears he likes....

i know that polar bears have hollow hairs, the rest im not very sure.\nbut the hollow in their hair has air which is a bad conductor of heat. thus having this layer of air in their hair helps reduce conduction of heat from their body and the atmosphere thus reducing body heat loss... kinda like those double layered windows you find in apartments in cold countries~ i hope this helps!

Polar bears view humans as prey, and actually enjoy killing and eating us. Lions are afraid of humans, and can be deterred by a blow to the nose. People wrestle alligators for fun, and win. Sharks are not interested in eating humans, and rarely attack, and they too can be deterred by a blow to the nose.

They can eat almost anything, so can Deer.  I had one eat a Satellite meter once that was laying on my back bumper, plastic and metal all gone.  I'm sure it's not good for them and they won't answer when I ask why.

Bears are thought to hibernate or sleep for 5 months to 7 months each year. In very cold climates bears may hibernate longer than in moderate climates, because the food supply in frozen climates is under snow cover longer. \n\nBears in captivity DO NOT hibernate at all because there is a ready food supply. Most bears do not eat, defecate or urinate during hibernation. This is accomplished through their metabolic systems. The bears appear to maintain the water content of their blood. The breakdown of fat reserves balance water losses. A small amount of urea is formed and is degraded and recycled into non-toxic elements. Much is yet to be known about this metabolic cycle. Grizzlies hibernate in dens. Some grizzlies utilize natural caves for dens, while others build dens in the sides of mountains, under hollow trees or other forested locations.

It depends.. iF htey live there all year round they have layers fo fat called blubber\nthey also have fur... polar bears have clear fur to collect heat and light and warm the bears. \n\nif they are travelling inbetween cold and warm( like humans d0)\nthey do things like shiverring and teeth chattering, also the blood rusehs to the skin to warm and away from the ears adn the feet to keep the inner organs warm

Depends what kind of animals! Some eat other animals.  Some forage under the snow for food.  Some eat tree bark, etc.  Some get fed by humans.

Crocodiles tire relatively quickly, and polar bears are well used to wearing down prey. They repeatedly strike at belugas who are trapped in the ice and are forced to surface at a single opening. They do this until the beluga is exhausted and dies.\nTemperature of the water is important for the crocodile , too cold and it would go into a torpor and die. If the water is not shallow enough, say that it is up to the bears shoulders, this would impede the bear and give the advantage to the croc.

<Bears eat both meat and vegetation.They are mainly omnivorous(eating both animal and vegetable foods), \n although some have a more specialised diet, such as polar bears. They eat lichens, roots, nuts, and berries. They can also go to a river or other body of water to capture fish.Polar bears are the largest type of bear, indeed one of the largest carnivores on terra firma. Sun bears are the smallest, only a bit smaller than the average woman.

Very few mammals actually hibernate.  Only a few small rodents that live in the far north (such as some ground squirrels) undergo a seasonal estivation during the winter.\n\nEven most arctic mammals remain active all year long.  Polar bear, caribou, arctic fox, bison, meadow voles, lynx, snowshoe hares, etc. etc. all live quite well through the winter.\n\nSome bears (black bears, brown bears) enter a state of torpor through the winter, but even they do not truly hibernate.\n\nAnother reason humans don't hibernate is that we didn't evolve in a cold climate where hibernation would be advantageous. \n\nHomo sapiens sapiens evolved in sub-Saharan Africa, and there are few cold winters there (even during Ice Ages).  The only way we can survive in northern climates is through our learned adaptations of technology:  fire, and clothing.\n\nLynx and wolves live and hunt all winter long without any clothes, and large herbivores like bison and caribou don't even have shelter.  How long do you think humans would last in Canada if they were naked and couldn't build a fire?\n\nOur niche is the savannahs of Africa.  People can (and do) survive quite nicely there without much in the way of clothing.  It's one of the reasons we prefer a room temperature around 22 C.  It could also be why we like having an expanse of short cropped grass dotted with one or two trees in front of our caves.\n\nWe evolved to fit into that particular ecological niche, and were able to adapt other niches to meet our needs with our technology.

There are a few species of fleas hardy enough to survive in northern climes, but even they are only able to thrive during the summer months.  During the winter they are not a problem, spending the months in diapause.\n\nDuring the summer, it is quite possible for a polar bear to get fleas, especially if they are living towards the southern end of their range where they are coming into contact with critters like red fox, wolves and dogs.  \n\nIt's unlikely that they would get a huge infestation of fleas though, and the fleas would not be likely to survive the winter.

i didnt know much about polar bears but because of your question i got to know a lot about polar bears while searching for it , but got bored looking for the right answer;),  hope this site helps you\nhttp://www.buschgardens.org/infobooks/PolarBears/home.html

I doubt a polar bear would be able to survive in tropical conditions, not to mention so many good-looking men being on the same island. ;-)

Penguins, bears and seals. Whales. That is a consensus. As for the flaura, lichen ... try looking the remainder up.

DONT FEED THE BEAR!!\n\nThey had a bear that lived in the front yard

Where's the challenge?\nI suggest you club polar bears. I hear there's more money in it.
