How Polar Bears are adapted to their Environment Essay

The Polar plump fors pelt is extremely thick and it traps the heat so well, you fag endt let away one in inferred vision. This is good be get the retention of heat keeps it permanently warm. It does non lose body heat as other animals and people do, and it would not be recognised by an inferred scanner, such as used when curious earthquakes and other devastated sites for survivors. The Polar bear would not be detected so this shows how well the bears pelt keeps its body warm, especially in icy frigidness freezing temperatures.Polar bears can go weeks between meals. Their digestive system, the like true carnivores, is also more adapted for processing meat than coif hidee material. Their large stomach capacity is designed to allow them to take favor of unexpected large meals which depart serve to tide them over during the gradual months when food might be hard to find. This would keep them from starving until they can find more food. However starvation is not a cause of d eath for the Polar cause, as their ability to store body fat, en commensurates them to go such long periods without food, that it would be almost impossible for the Polar Bear to go hungryThe necks of Polar Bears atomic number 18 longer than their nearest kin, the brownness bear. This adaptation establishs it easier for them to keep their heads above water when swimming, and, like others, enables the Polar Bear to live in the somewhat harsh Artic environmentThe forepaws on a Polar Bear are very large. With a diameter come up 30 centimetres (12 inches) and partial webbing between their toes, Polar Bears are able to use their front feet much like paddles to propel them rapidly by the water. This helps them to catch their pray, as they can swim very fast so their pray doesnt get away.The hind feet are slightly smaller. On both the front and hind feet, the bottoms are covered with dense fur which affords better traction when moving on ice. This helps them to move quicker, whether they are rill away from predators, or running towards their pray On land though, they are not as quick as brown bears and appear to take on traded morose speed for their extremely massive forelegs which they use to break through with(predicate) seal dens or flip a largeseal out of the water. They are able to attain speeds of 40 kilometres per hour (25 miles per hour) for short distances.The sharp teeth of Polar Bears have re-evolved changing back from a blandish crushing surface to a sharper-edged surface suitable for shearing off bite sized chunks of meat from their prey. Also, the canine teeth, used for seizing and attribute prey, are longer, sharper and spaced wider apart than in brown bears.The good fur the polar bears are covered with is varied from pure exsanguine to more of a yellow hue. The white fur is important camouflage for the bears as they hunt their prey out on the ice pack. The turn up consists of two layers an under finishing of fine white hair and outer coat composed of long guard hairs. The individual guard hairs are hollow. This gives the fur an actual translucent effect The hollow hairs also help to make the Polar Bear morebuoyant when swimming.The actual colour of the kowtow of the Polar Bear is black. It is thought that this is an adaptation for better heat retention.The distaff polar bear has developed a unique endurance technique when it comes to the development of an embryo. It is called delayed implantation. Delayed implantation clearly serves an important survival need for the mother. Should the female not have put on replete fat reserves before the time to den arrives, the embryo will not implant and it is simply reabsorbed by her body. She will then traverse her winter hunting out on the pack ice.
