The polar bear is a large-sized bear with a white color and settles in the Arctic Circle that includes the Arctic Ocean in addition to the oceans and the glaciers surrounding it. Polar is the largest animal-eating meat present today, and although polar bears are among the sister species of brown bears, they have evolved from them to live in narrower environmental conditions while obtaining many physical properties that make them adapt to low temperatures, in addition To make it to be easily navigated across the icy terrain, water and snow.
Polar bears are classified as marine mammals because they spend most of their lives at sea. Polar bears are the only marine mammals that have strong limbs and feet that are air-conditioned for miles on land. Polar bears prefer sea ice that sits on huge areas of water over the continental shelf, and owns the surrounding areas Arctic Circle has a large percentage of biological diversity, unlike the deep water found in the Arctic, and polar medicine is preferred to be found in areas where sea ice and sea water converge, which gives a favorable environment for seals that are an important part of the polar bear diet, and therefore the bears Polar is mainly found along glaciers instead of the polar basin, which contains a few groups of seals, and groups of polar bears were monitored in the south of Labrador and Norway in addition to James Bay and St.
Lawrence Bay, and polar bears are located near the border between the semi-regions Polar and humid continental climate regions, and can also be found on Greenland Island, Russia and the United States.
Polar bear food and reproduction
Seals are the main food source for polar bears and their diet depends almost entirely on meat. If food supplies are available from seals, polar bears prefer feeding on seals only, as this high-calorie diet provides the polar bears' needs of fat that maintain their health and help them in Maintaining its body temperature, so that a polar bear needs about 2 kg of fat per day which provides about 121 pounds of seals meat and supplies the polar bear about eight days of energy, and if the polar bears do not find enough seals they can feed on anything that can You can find it like fish, reindeer, rodents, birds, berries, and human litter.

A female polar bear usually gives birth during November or December after an eight-month pregnancy period, and a female polar bear prepares for the birth process by digging a snowy cave in which to give birth to her young and this cave is called a maternity cave, and the female polar bear usually gives birth to twins although it has been Record cases in which the female gives birth to a single baby or a triplet twin, and the weight of the newborn at birth is about half a kilogram but grows very quickly, and the cubs depend entirely on their mothers for the warm and creamy milk that contains 36 percent fat, and by the spring The cubs go out of the maternity cave to explore their surroundings as they become fully mature at the age of two years, and the polar bear’s life span ranges from 15 to 20 years.

Polar bear adapts to its environment Polar bear has many characteristics and features that allow it to stay, grow and swim in a very cold environment, where polar bears possess paws and claws that help them walk on ice, and the polar bear has sticky bumps known as papillae in his paws that provide him with a fist They are strong on icy lands, and polar bears possess large feet of about 11 inches that help them walk on thin ice sheets without sinking by distributing their body weight over a larger area, and the polar bear fur is made of a dense buffer layer topped by a layer of hair, Fur works to isolate the body and reduce its loss of temperature, and it is interesting that the polar bear fur is not white but rather transparent and does not contain any pigments and works to reflect and disperse visible light as snow and ice do, and this type of adaptation helps protect the polar bear from height Temperatures, especially in the summer, and the skin of the polar bears is black in color, and underneath there is a thick layer of fat that can reach up to 4.49 inches thick and acts as a heat insulator.
Risks facing the polar bear
The International Union for Conservation of Nature in the Arctic and many prominent biologists have expressed grave concern about the impact of climate changes and global warming on endangering polar bears, and the main risk from climate change is the polar bears' exposure to malnutrition or hunger. Resulting from loss of habitats, where polar bears rely mainly on hunting seals that are located in the areas of sea ice, and high temperatures resulting from climatic changes lead to melting sea ice early in the year, which causes polar bears to go to the beach before Building enough reserves of fat to survive during periods of food scarcity, and the melting of the marine ice cover is forcing the bears to swim for longer distances which increases the possibility of their energy reserves running out and sometimes leads to drowning, and with high temperatures the sea ice tends to be thin Which makes it difficult for polar bears to reach seals, and inadequate nutrition causes lower fertility rates in adult females and a decrease with Signs of survival in young cubs and bears, in addition to the weakening of the body in bears of all ages.
