Polar Bears part 2 The reach sexual maturity at 3 or 4 years and mating period occurs in the months of April and May where male and female live together, in the case amicably to gradually relate. The male may follow the tracks that the female leaves up to 100 km or slightly more and fight with other males to the degree of being wounded, scarred or broken teeth. All to determine who has the right of reproduction. The white bear is polygamous, so the female can have puppies of different males. Once fertilized the egg, this is in a suspended state. To do this, females awaiting a breeding refuge in winter, but before that store large amounts of fat in your body and they do not feed during that period. After birth, the pups feed on milk, which causes the mother to lose a lot of weight. For summer should recover completely. Puppies are born with 30 cm high and 700g weight, lacking teeth, eyes and some force, but in five months grow so fast that may already accompany the mother in exploration. Together spend five months in the cub learns to get their food and to protect polar bears from other adults who often eat small fry. In some cases they can live up to two and a half years. 6) They together represent a danger, especially when clashes between adults and cubs are given. Similarly, larger walruses can be considered as a threat, although this is not very common. Over the years, man has hunted polar bears to provide themselves with their flesh and skin. In other cases, simply for sport or the false belief that attack humans. This does not happen as long as you do not feel threatened in their natural habitat, like any other animal. In 2008, the immoderate hunting nearly caused the extinction of this species, but organizations for the environment, these human actions banned in several countries established or authorized to hunt certain amount per year limits. On the other hand, equally alarming is the problem of global warming caused by the melting of ice representing a constant for this hazard and other animals that live in the same conditions, forcing the white bear to retreat to land and take actions that change by complete their reproductive cycle. This has caused the decline of polar bear births

Polar Bears POLAR BEAR 1) The polar bear or also known as white bear, belongs to the species of the world's largest carnivorous mammals. He lives in the northern hemisphere of the Earth and is considered a great predator knew. It can live up to 30 years. 2) These mammals measured 2.4 to 3 meters long with a weight of 350-700 kilos in the case of males, and 1.8 to 2.4 meters with 150-250 kilos of weight in females. His body is perfectly adapted to the type of habitat and the extreme conditions of this. That is why it has legs developed to withstand long walks and to swim long distances. His ears and tail are small to maintain body heat. To regulate its temperature, your skin has a thick layer of fat and a thick coat translucent formed by thousands of air-filled hairs that keep it at a standard temperature.

The white color of your hair is rather a reflection of the light and not the color itself. 3) As you mentioned at the beginning, living in the northern part of the planet, encompassing Canada, Greenland, Denmark, Norway, Russia, Alaska and Iceland with some specimens. The landscape they inhabit is typical of an atmosphere of tundra: vast, snowy and seemingly without a trace of life. In summer often it looks different in some areas, as higher temperatures cause melting and the entrance to the plant life. The polar bear is a mammal adaptable to their environment, but seasonal changes may also be a problem in relation to food availability. 4) This carnivorous animal feeds on baby seals and sometimes reindeer, coming in to eat up to 30 kg of food daily. Because the water is salt such places not consumed, and therefore the necessary fluids advantage blood their dams. The humans have been studied cannibalism cases, mainly from males having food shortages opt feed on some other young or weak polar bear. 5) The reach sexual maturity at 3 or 4 years and mating period occurs in the months of April and May where male and female live together, in the case amicably to gradually relate.
