how do polar bears camouflage themselves more completely when hunting?

They hide their noses and close their eyes.

Sorry i dont know the answer but that is sooooooooo sweet! Every creature matters. I watched Planet Earth on T.V last night and it was heartbreaking to see how the Polar Bears are suffering. We need more caring people in this world! Bless ya.

I know polar bears are adapting to the warmer climate by getting darker/thinner fur but I don't think they are becoming extinct.

Bear is edible because they are mostly plant-eaters.There are many bear hunters who fill their freezer, like deer, elk, and moose hunters. On the other hand, lion, tiger, and other carnivores taste terrible. They are not hunted for their meat, they are hunted either as a defensive measure or for the "trophy" - head, skin, or both.\n\nPeople who "trophy hunt" simply want to be able to brag about what they've hunted. Like having the most expensive car, the biggest house, etc. What usually makes it even more inane is the fact that they're not even pitting themselves against the animal. They have trackers and shoot from long distances to kill their prey - it's not really much of a sport at all.

Bears have a diet that is mostly based on berries, fish and the occasional animal that might wander around.  Berries are missing in winter, and fishing is hard to do owing to the ice that covers lakes (and fish are not as active anyway), and looking for the odd animal it could catch would be time and energy consuming; perhaps not a good move from an energy point of view (the bear would spend more energy to hunt that it owuld get from eating the animal it could catch; bears are solitary animals as do not have the hunting success a pack of wolves might have).\n\nSo, it makes good sense for them to "close" shop for the winter, and live off the fat they accumulated in the summer and fall.

Camouflaged Animals:\n\nCOLOR CHANGE\n>>Reptiles and Amphibians (like frogs, toads,chameleon) and some fish can change the colors of their skin or scales to match a surface that's near them. Their coloration is determined by biochromes in living cells. Biochromes may be in cells at the skin's surface or in cells at deeper levels. These deeper-level cells are called chromatophores. Cuttlefish species, can manipulate their chromatophores to change their overall skin color. Chameleons can produce a wide range of colors and patterns on their skin, but they do this primarily to express mood, not to blend in with different environments.\n \n>>Mammals (like deer, squirrels, or moles) have earth tones color to match trees or dirt.\n\n>> Far north  animals often have white fur or feathers in winter. When spring melts the snows, the white fur and feathers fall out. Pigments in the skin cells change. When new feathers and fur grow in, they match the new color or pattern of the landscape.\n\nCOUNTER SHADING\n>> Mice, white-tailed dear, Canada geese, otters and largemouth bass use a kind of camouflage called counter-shading. These animals have bodies that are dark on top and light on the bottom.When sunlight shines on an animal's darker colors, it makes them look lighter. When the animal's lighter-colored parts are in shadow, it makes them look darker. The two areas of color blend together when seen from a distance. The animal's outline is harder to pick out from surrounding patterns. \n\nELEMENT OF DISGUISE\n>>Insecta (like green katydid or grasshopper) - have a solid body color that matches the color of its environment. Many insects that feed on plants have solid green bodies during part or all of their lives\n\n>>Many animals have distinctive designs on their bodies that serve to conceal them . These designs, which might be spots, stripes or a group of patches, can help the animal in a couple of ways.This disruptive coloration is particularly effective when animals in a species are grouped together. To a lion, a herd of zebras doesn't look like a whole bunch of individual animals, but more like a big, striped mass. The vertical stripes all seem to run together, making it hard for a lion to stalk and attack one specific zebra. The stripes may also help a single zebra hide in areas of tall grass. Since lions are colorblind, it doesn't matter that the zebra and surrounding environment are completely different colors. \n\n>>Walking stick, an insect that looks like an ordinary twig. A predator can easily distinguish a walking stick from its surroundings, but the predator thinks its only a stick, and so ignores it. \n\nIMITATION\n>>Swallowtail butterflies and many insects often use a kind of camouflage called imitation. The shape of their bodies, along with their coloring, makes them look like other things.\n\nMIMICRY\n>>Viceroy butterfly and many harmless insects use mimicry.The monarch butterfly is a bad-tasting insect that most birds will not eat. The viceroy butterfly has a black-and-orange wing pattern that closely matches the monarch's. Birds who see a viceroy leave it alone, thinking it's a monarch. Many harmless insects look and fly like bees, insects which can really sting.♥\n\nFor more camouflaged animals visit this link:\nhttp://www.enchantedlearning.com/coloring/camouflage.shtml

When fall turns to winter and the temperature dips, the food sources for the wild animals becomes very scarce.  Some animals wait out the harsh conditions of winter, constantly searching for food and shelter.  Other animals, like the bear, spend the winter in hibernation. \n     Hibernation is a dormant sleep-like state.  By going into hibernation the bears bypass winter when their food supply, nuts and berries, disappears.  Animals like the bear would find it extremely difficult to find enough food during winter, and therefore go into hibernation. \n\n     During hibernation the bear cuddles up in a cave or in a hollowed out tree, safe from the dangers of winter.  In order to survive this long period of inactivity the bear must build up its body weight by accumulating fat.  In the months before  hibernation bears can gain up to forty pounds of fat per week.   A bear’s body goes through several changes once it enters hibernation.  Its heartbeat drops from fifty-five beats per minute to ten beats per minute, and the bear’s body temperature will drop from five to nine degrees below normal.  While in hibernation the bear uses  the stored energy it accumulated as fat to survive.  So a bear can lose from fifteen to forty percent of its body weight during the winter just by sleeping! \n\n     Bears will generally enter hibernation in early October and emerge sometime in April or May, when their food is plentiful again.  The hibernation cycle is just another unique adaptation of nature that allows many animals like the bear to survive during the severe conditions of winter time. \n\nhope this helps.

With great difficulty. Penguins tend to huddle together to stay warm. Polar bears have black skin and hollow quill like fur that collects sun energy like a solar water heater. Nature has adapted many polar animals, and even Eskimos with unique abilities that are very individualized for survival.\nGreat question!

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 are much bigger than tigers. On an avarage, a polar bear is 5 ft taller than a tiger. Besides both are predetors, so both has killer moves up their sleeve. So I would imagine the polar bear has some advantage. Now the question is where would the duel take place? Tigers are used to warmer climates, polar bears may be in trouble there. On the other hand, if the fight is held at the polar bear's domain in the poles, the tiger would be shaking too much in cold to put up a decent fight.

What I have seen is they are a few of them going through the jungle to get to higher land so that the transmitter will work when "the monster thing" starts to come after them. One of the guys has found a gun and shoots at it and kills it. When they find out what it is, it's a polar bear.

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

Yes they can. Their senses are much more acute than ours. They can hear the rumblings below and the first to be aware are birds. This also triggers off the bears instincts that something abnormal will happen though they don't know exactly what.

According to several websites I've checked out, they hunt for bear and other wild game.  Just what you'd expect them to.  They also fish.

Polar bears are white because the pressure at the poles is low, so they have to be able to absorb heat. \n\nPressure makes you cry if it's too much. \n\nPressure in your bladder makes you have to pee. \n\nPeer pressure makes girls comb their hair...Otherwise we wouldn't bother! \n\nCelebrities usually crack under pressure. \n\nMany normal people will shine under pressure. \n\nPancakes turn brown thanks to pressure generated by the heat. \n\nChampagne will bubble until the pressure of the carbonation has disappeared. \n\nIf you squeeze something under pressure, BAM, there it goes. \n\nIf you are "looking" at pressure, you're in it, like in an airplane, and your ears pop.
