Polar Bear Is The Largest Land Carnivore

The Kodiak bear is a very unique bear, different from other bears but similar at the same time. They have adopted to the ways of living on the islands, learning to survive with many other of their own kind. People should know more about this bear and how its lives affect ours. I’m hopeful this report will interest people into learning more about the Kodiak bear. The Kodiak bear, the largest bear in the

Grizzly Bears aggressive predators and have incredible strength. They are usually twice the size of a black bear. Male grizzly weighs up between 400 to about 900 pounds. Female grizzly weighs up to about 200 to about 500 pounds. They can run up to bout 40 miles per hour. They can stand on their hind legs giving them advantaged to defend or fight another predator. They came from Asia and little bit from Europe. They can live up to over 20 years. Their hump on their back allows them to run fast and be powerful when it comes to hunting their

As members of the mammal family, the giant panda and the polar bear share many of the same physical characteristics. On the other hand their appearances set them apart from one another in many ways. To start with pandas and polar bears are well alike and different in many ways. When being born pandas are about 15-17 centimeters long. Polar bears on the other hand though are born about 30-35 centimeters long. Pandas over the time grow and are white with big black spots around their body.

The bear have evolved along time ago and now there is only eight species existing. They evolved from early canids during the late Oligocene and early Miocene, about 25 million years ago. The earliest ancestors where the Dormaalocyon Latouri. An intermediate ancestor was the short faced bear, very similar to the modern day bear. It lived through the pleistocene period. It grew to thirteen feet long and was a herbivore. The ancestors to the modern day bears lived in the same climate and ate the same things. The modern bear contrast from the ancestor because the ancestor was more skinny and was smaller, and it was more cat like. The eight species of bear that still exist. They are the Polar bear, Brown bear, American black bear, Asian

The Grizzly Bear is a Keystone species. A keystone species is the center block, of which an ecosystem largely relies on. The Grizzly Bear lives in places such as alpine slopes, avalanche shoots and lower elevation wetlands.

Polar Bears rely upon sea ice for survival. They hunt on seals that are found on sea ice. Climate change and the atmospheric warming have caused the Arctic ice to melt, resulting in loss of habitats for polar bears. This essay will focus on how has climate change and increase in temperature affected the polar bears and what can we do about it.

The Polar Bear (Ursus maritimus) is a bear native largely within the Arctic Circle encircling the Arctic Ocean, its surrounding seas and land masses. Although it is closely related to the Brown Bear, it has evolved to occupy a narrower ecological forte, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet. Though there are many theories surrounding evolution, the two stand outstanding hypotheses applying to the modification from Brown Bear to Polar Bear are Lamarck’s theory of Use and Disuse, and Darwin’s theory of Natural Selection. The intention of this paper is to compare these thesis and determine the most appropriate in

Polar bears are just one kind of animal you can find on the tundra did you know the tundra is the coldest biome of them all? The climate, producers, and consumers, are all parts that make up the tundra.

Differences include the size of legs, ears, noses, paws, claws, jaws and the colour of the bear's fur. Polar bears generally have larger legs, smaller noses and ears, soft paws, short claws and small jaws with strong teeth. These adaptations have occurred to improve the polar bears wellbeing and chance of survival whilst living in the Arctic. Whereas, Brown bears have larger and more claws and a heavier and larger skull (Difference Between, 2014). This is too to help them survive in the environment.

The Ursus Arctos otherwise known as the grizzly bear lives in North America around Northern Canada, Alaska, Wyoming, Montana, and Idaho. A grizzly bear lives in the wild and hunts for its food such as fish, deer, elk, or any other animal. They live inside of caves for protection from the weather, they will also live under trees or anything that will provide them shelter. I believe that grizzly’s have evolved into animals that can survive in many climates and environments.

Polar bears are the top predator in the tundra biome. The polar bear mainly eats seals. Polar bears are the largest land carnivore on earth, their average weight is 990 for males, and 500 for females. Polar bears have white fur, but black skin. The black skin is used to absorb sunlight for warmth, while the white fur is used for camouflage.

Grizzly bears are a very unique type of bear. The bear has long sharp rounded claws. They also have large muscles in their back that help them dig. The bear has grizzled fur to help distinguish them from black bears. It is very important that we do everything to protect the Grizzly population.

White bears require a variety of physical characteristics to survive in the harsh environment of the Arctic. Large, wide paws with bumps allow them to distribute weight and grip more efficiently. Water resistant fur with a luminescent quality keep the bear warm and dry. Additionally, Sharp and powerful teeth have the ability to penetrate hard flesh. These special features allow not only the ability to thrive in a difficult environment, but also are important for communicating with other species and another bear.

The polar bear, the largest land carnivore in North America, one of the largest animals in the world and a favorite at zoos worldwide, has, over the years, adapted to its harsh Arctic environment. The appropriately named ‘ursus maritimum’ or sea bear usually lives between 15 and 18 years in the wild and spends most of its life on ice. It is the most recent of the eight bear species. The first polar bear was a brown bear subspecies, with brown bear dimensions and brown bear teeth. The polar bear evolution was rapid due to the small population and extreme pressure to survive. Even today, the polar bear continues to evolve to better adapt to the harsh realities of Arctic life.

 The polar bear has to be able to stay warm in the harsh winter cold. In fact sometimes because they have such thick fur they have to lay down on the snow to cool off so the harsh cold isnt even enough to keep them up to tempreture.
