The marine mammal the polar bear lives in the countries that make up the Arctic Circle, which would be countries like Canada, United States but only the state of Alaska, Russia,
Norway, and Greenland. Roughly 60% of the world’s polar bears live in Canada. Polar bears do not live in the Antarctic.
At birth, polar bear cubs weigh about 16-24 oz. When born the female cubs are slightly smaller than the male cubs. Polar bear cubs are born small and helpless, with their eyes closed.
By eight months the cubs weigh more than 99 pounds. When they get to be full grown the male will weigh anywhere from 900 pounds to 1100 pounds. The worlds heaviest recorded weigh of a male polar bear was 2,209 pounds. When a female polar bear is full grown

When a baby polar bear is born it is about 30 cm or 12 in. long. The way scientist measure how tall a polar bear is, is by measuring the polar bear starting at its shoulders and going to its end point. When you measure an adult male that way then it is usually 3.5 to 5 feet.
When standing on its back legs an adult male can be up to 10 feet in height. That is as tall as a one story building. The male polar bear can grow to be three times the size of the female polar bear. The world’s tallest recorded polar bear was a male that was 12 feet long. This explains why the polar bear is considered to be the world’s largest land carnivore. When a baby polar bear cub is first born he or she looks hairless, but really it is not.
When born a baby polar bear has very fine fur, which can be easy mistaken as nothing being there. They don’t get their signature fluffy white fur until they are about two months. Right around that same time is when they get their teeth. By the time the polar bear reaches its adult life it has gotten very dense white hair, that consists of different layers and lengths of fur.
Polar bears also look their whitest after they are clean and when the sun is high overhead.

It doesn’t matter if it’s on land or at sea, a polar bear’s skin prevents nearly any heat loss. They mainly rely on their blubber when in the water to keep them warm. As a baby a polar bear will feed on the mother’s milk until his or her mother decides to teach the baby how to hunt. As a polar get older his or her diet changes. He or she will go from a diet of mothers to a diet of an adult polar bear. An adult polar bears diet consist of seals, carcasses, beluga whales, and adult walruses. Seals are a great form of nutrition for hungry mothers and growing cubs. a polar bear can get 8 days of energy from a 121 pound seal.
Polar bears often only eat the fat of the seals and leave the rest for other animals such as foxes , ravens, and other bears. When seals get scares polar bears tend to snack on carcasses of other dead animals. They can detect the scent of a dead carcass up to 20 miles away of dead beluga whales, grey whales, walrus, narwhals, and when they can they eat bow head whales. When food gets really scarce polar bears even resort to searching for food on land and scavenging.
grizzlies will hibernate when there is a seasonal shortage of food, low environmental temperatures, or when there’s snow arrival. Grizzly bears hibernate five to seven months each year. The grizzly will enter into hibernation in October or November. During this time the grizzly bear must prepare a den and consume as much food as possible to last their hibernation period. While searching for a den the grizzly may travel many miles until it finds a suitable area that it likes. The dens are usually at elevations above 1,800 m (5,900 ft) on north-facing slopes. The reason why bears have to eat as much food as possible is because they need the energy from the food to last through the entire winter. They may eat up to 90 lbs of food per day, while trying to put on as much weight as possible. When it’s time for grizzlies to hibernate; will enter their den, and fall into a “deep” sleep. During this time the grizzlies won’t eat or drink; but instead they digest their stored up fat; (the fat used to last them through their entire hibernation.) The bear also will not urinate or defecate, but will reabsorb their urine and feces into proteins. The bear can use 25-40% of their body weight during hibernation; the bear’s heart rate and body temperature may also drop. By March or April, male grizzly bears usually emerge from the den and the females emerge in late April or May. When bears emerge from hibernation they’re
The Grizzly bear are really interesting. Grizzly bears are dangerous and they eat a lot of thing but there diets are berries,roots,seeds,dead animals,fish,elk,insects,and other foods that they find. Grizzly bears are mammals and they are unpredictable and really dangerous. Grizzly bears live in many different areas they live in california,Ohio,Wyoming and in western Canada. But bears are also found in open Plains dense forest.
The Tundra suffers a very harsh climate. Because of this fact most of the area
Grizzly bears live in a variety of environments .All of which includes dense forests, subalpine meadows, open plains and arctic tundra . In the past though, they could be found from Alaska to Mexico, and from California to Ohio. Though Nowadays there are efforts trying to make it so grizzly bears can make a comeback and the wild, and all of their efforts are proving to be working, there are 4 times as many grizzlies in the wild as there were in 1975, at
3. There are many things to know about Polar Bears. One thing is that they are a very endangered species. Only about 40,000 remain in the wild. Another thing is that Polar Bears are not really white. Their fur is made up of clear tubes. These
First I’m going to talk about black bears habitat. Black bears live in swampy areas. They can also be found in mountains. Black bear are native to North America. They can also be found in canada and northern mexico.They also have to live in a place where there's food and water.
All mammals have a dome form of hair or fur on their body. Fur is a key benefactor in protecting against harmful sun rays, cuts, or bacteria. It can also allow animals to blend into their surrounding in order to avoid predators, or in some cases hunt prey. Although hair can be seen to hold many benefits, there have been many animals who evolved to have little amounts of hair for some sort of purpose. Some examples include species that live underground or in the ocean. Mammals such as elephants are prone to get overly hot because their large bodies, so they developed hairless skin in order to combat the onslaught of gaining to much heat.
The bear looks as if he is looking inside of Denver's convention center because Lawrence knew the convention center is where many meetings are held for companies to go and share different ideas to one another. Lawrence wanted the bear to look as if he is curious of what was being talked about. The bear is 40 ft. tall and is made of fiberglass and steel. When you see it in person it almost looks plastic because of the unique texture it has. Lawrence wanted to make the bear look as if it was a big toy because of the toys his son owned. Lawrence also explained how he did not intentionally want the bear to be blue. The bear originally was supposed to have a more sandstone color base but because of a printing mistake, he got the idea of making it a bold blue. He later discovered that the Native American Tribe 'Ute' who are from Colorado valued the black bear and also found the color blue to be spiritually enlightening, so he decided to keep the bear
The Arctic climate is covered with snow and ice. The temperatures are very cold. The Polar Bear’s coat has two layers of fur and a layer of blubber (thick fat) underneath. Polar Bears use their big front paws to paddle through the water and their oil coated fur helps keep them dry when they get out of the water. A Polar Bear spends months wandering across the frozen surface of the Arctic, looking for food. They eat walruses, birds, fish and seals. Sometimes a Polar Bear has to spend a lot of time in the water searching for food or swimming from place to place to find something to eat.
The brown grizzly bear is heading north as sea ice melts in the north, causing big problems for its white-haired cousin, the polar bear. Rising seas and sinking reefs are causing beaches near Florida, Hawaii and the Virgin Islands to lose alluring white sand.
This isn’t necessarily the case. A typical diet for a polar bear revolves around sea lions, which gives polar bears enough energy to survive and reproduce. They were able to use this main source of food for their energy. These sea lions are not enough to support their energy needs anymore. Now, they have to look for other terrestrial food sources that can provide them with more energy. Subadult polar bears appear to come ashore before more mature individuals and the earliest subadults are beginning to overlap the nesting period of the large colony of snow geese also occupying the Cape Churchill Peninsula (Rockwell and Gormezano 539). Direct observations of nest predation showed that polar bears may severely affect reproductive success of the barnacle goose (Branta leucopsis), common eider (Somateria mollissima) and glaucous gull (Larus hyperboreus) (Prop 1). This is now starting to effect bird populations around the globe because polar bears are using the birds’ eggs as a source of energy. Jouke Prop goes on to say that over 90% of all nests are being predated
They mainly feast on Ice Seals which have a large amount of blubber. They need a high fat content and many calories to maintain their health, and can eat 100lbs of blubber in just one sitting (PolarBearsInternational, n.d.). If they do not get a proper nutrition they can drown, starve, or freeze to death. With the ice in the Arctic retreating, it’s a lot harder for Polar bears to hunt. Usually they find breathing holes carved out by a seal using their strong sense of smell. Then they wait patiently until the seal surfaces, which could happen in a few hours to days (PolarBearsInternational, n.d.). For Polar bears, this is one of the most effective ways of hunting, other than stalking seals basking on the ice. With the ice melting, there are less and less breathing holes for the Polar bears to easily catch their prey. Catching a seal is not an easy task, and it’s even harder for a malnourished Polar Bear (PolarBearsInternational,

The Humpback Whale, Megaptera novaeangliae, is part of the marine mammals group. They are found in oceans all over the world, they live in open waters. Even though they are mammals, they do not live on land (Monterey Bay Aquarium). Humpback whales are known for their magical song that can travel great distances. These gentle giants are omnivores, their main diet is krill. They are mostly found near coastlines feeding on tiny shrimp-like krill, plankton and small fish. Humpbacks migrate annually from summer feeding grounds near the poles to warmer winter breeding water closer to the Equator. Humpback whales are powerful swimmers, and they use their massive tail fin, called a fluke to propel themselves through or even out of the water! Mothers and their young swim close together, often touching one another with their flippers with what appears to be gestures of affection. Even though it takes more than one year for a humpback whale to grow fully, mother whales leave them after one year (National Geographic).
The first bear of that I will inform you on is the Polar Bear also known as the Ursus Maritimus. The polar bear doesn’t have a very large diet, they mostly eat ringed or bearded seals because they need large amounts of fat to survive. The average length of a Polar Bear from head to foot is from six to nine feet. On average a Polar Bear weighs from 800 pounds to 1300 pounds. Polar Bears have been classified as endangered as of May of 2008. Polar Bears may not seem very dangerous but they can be. “In the past 20 years six people were killed by polar
