The polar bear is one of the largest animals in nature that can live in places with the lowest temperatures on Earth. Contrary to what many think, the polar bear's fur is not white, the fur is free of pigment, the white appearance is due to the reflection of light. Its skin is black and thick. To protect themselves from low temperatures, bears rely on an insulating layer of fat (11 cm thick. Although it is related to the brown bear, this species evolved to occupy a narrow ecological niche, with many morphological characteristics adapted to low temperatures temperatures, to move over snow, ice and water, and to hunt seals, which comprise the largest portion of their diet. . The species is classified as "vulnerable" by the International Union for Conservation of Nature and Natural Resources (IUCN), with eight of the nineteen subpopulations in decline. Among the threats that affect the bear are the development of the region with the exploration of oil and natural gas, contamination by pollutants, predatory hunting and the effects of climate change on the habitat. For hundreds of years, the polar bear has been a key figure in the cultural, spiritual and material lives of the indigenous peoples of the Arctic, appearing in many of their legends and tales. This is without a doubt one of the most fantastic and wonderful animals in nature. . #amazing #amazingvideo #world #beautiful #Wonderful #wonderful #animals #animais #bear #polarbear #beard #ursos #panda #naturelovers #nature #natureza #Love - @theamazing.world
