The young little polar bear followed his mother towards the cool Ocean, delighting as he stepped into it. It was the first time that he had ever touched water. He splashed around, his instincts telling him exactly what to do, how to swim. This is the beginning of a polar bear's life, after a few weeks of nursing and nourishment. The mother will teach him how to get his meals (mostly seals), and all the other things necessary for survival. In this paper,several questions about the polar bear will be answered. The first question is, why are polar bears considered marine mammals, the second, what distinguishes a polar bear from other bears or mammals, and last but not least, what are the main threats that polar bears face?

Well, there are several facts that illustrate that surprisingly well. Polar Bears International.org reveals that “Polar bears' fur consists of a dense, insulating underfur topped by guard hairs of various lengths. It is not actually white—it just looks that way. Each hair shaft is pigment-free and transparent with a hollow core that scatters and reflects visible light, much like what happens with ice and snow.” In addition to having transparent fur, their skin is actually black. That is so their skin can absorb heat quicker and retain it longer. When polar bears want to play, they begin head wagging. Yes, that is the legitimate name for it. The adults are the ones to initiate the play, and when they do, they stand on their hind legs, lower their chins, and move their paws to the side of their body. Then they proceed to mock battle, proving their strength in a fun and beneficial way, by increasing coordination and hunting …show more content…
A great example is Global Warming. The effects of Global Warming are things like population decreases, scarcity of prey, and loss of sea ice for them to dwell upon. As well as having less ice to rest on and generally live, when the ice melts the platforms become spread farther and farther apart, meaning they have to swim farther. Polar bears prey are becoming harder and harder to come by as well. NWF.org says that “Polar bears are going hungry for longer periods of time, resulting in cannibalistic behavior. Although it has long been known polar bears will kill for dominance or kill cubs so they can breed with the female, outright predation for food was previously unobserved by biologists.” And as for population decreases, The US Geological Survey predicts that two thirds of the population will have perished by 2050, largely because of prey
