It really can't be fake, and it can't be fake. Even if they look alike, they are not brothers. Bears always give us the impression of being kind and cute, there are so many varieties of bears in the world, all kinds of colors, but also have different combat effectiveness, beautiful white polar bears, stupid brown bears, they all seem to have very similar faces, but the color is different. Today we will learn about the world of these bears.
Bear is a collective name for carnivorous bears, black bears are a species of bears, mainly divided into two subspecies: Asian black bears and North American bears.
1. Distribution area
Polar bears are the oldest and most classic Arctic land animals, they always wear a mink coat to protect themselves from the cold of ice and snow, in the Arctic, polar bears are a dominant existence.
The Asian black bear is a widely distributed mammal, found all over the world, mainly living in East Asia, such as China, the Russian Far East, and India, and in the mainland is mainly distributed in Guangdong Province, Yunnan, and Guangxi. It is not difficult to meet Asian black bears in these areas.
American black bears are only distributed in the Americas, mainly in Canada and the United States, and in some famous mountains, you may also see them shuttling among them, such as the Rocky Mountains.
Second, the appearance characteristics
The appearance characteristics of the polar bear do not need to be introduced too much, because it has white hair throughout. No other extra colours.
An adult polar bear weighs about 350 to 700 kilograms, and an adult female polar bear weighs about half the weight of a male. It also weighs a lot less, only 150-600 kg. The ears are small and round, but it should be noted that the skin of polar bears is actually black. It's just covered by white hair. The volume of polar bears is relatively large among all bears, the largest can reach a ton, followed by brown bears, with an average of about 200 pounds.
North American black bear's limbs are relatively short, eyes are also small, round, is now the world's largest number of bears, looks stupid, their body length is only about 1.5-2.5 meters long, the volume of male bears is much larger than the volume of mother bears, in all bear volume rankings, North American bears rank third in size. North American black bears generally walk on all fours. Their coat color is black, with very few gray and brown colors. In the Alaska region of the United States, a blue-gray black bear is distributed.
Asiatic black bears, like polar bears and North American bears, have round ears and small eyes. As well as strong ear bodies. Weighing around 50-200 kilograms, their bodies are also tightly wrapped in black fur, and Asian black bears are distinguished from North American black bears in that they have a V-shaped white patch on their chests. Some are yellow patches. This crescent-shaped mark is therefore known as the moon. The shoulders are smoother and the hips are slightly larger than the shoulders. In short, the Asian black bear looks slimmer and smarter than the North American black bear.
3. Life habits
The polar bear's lazy character makes it lie down on the ice most of the time, or skate on the ice, and sometimes wait for prey to appear. By incomplete calculation, polar bears spend most of the year lying still. Due to living in extremely cold areas. Surrounded by the ice floes of the Arctic Ocean, polar bears' food can only be limited to the Arctic Ocean, fortunately, polar bears are natural swimmers.
Therefore, seals, seabirds, and fish in the Arctic Ocean are all in the pocket of polar bears. Living in such a harsh environment since childhood has made polar bears one of the top hunters in the polar region. He also became the king of loneliness on the ice.
Asian black bears mainly eat some vegetarian food, don't look at the parents are so big, but people don't like to eat big fish and meat. Asiatic black bears mainly eat the roots and fruits of some plants in the forest, as well as seeds, and even the insects on the trees. This is also because Asiatic black bears mainly live in deep mountains and hills, which is why Asian black bears have super climbing ability. It's easy to climb up cliffs as well as trees with ease. Asiatic black bears also have a few names called black blind, because Asiatic black bears have extremely poor eyesight,
Asiatic black bear feeding is also affected by the season, in the spring, it mainly eats some juice-rich plants, including grass, leaves, wild vegetables, etc. in summer, because it is too hot, it will eat some plant fruits. Of course, the Asian black bear also eats meat, but it only likes to catch some small animals, such as insects and fish.
The North American black bear is also an omnivore, living mainly at altitudes of 3,000 meters, and in North America, it always hides in some mixed forests. North American black bears are also powerful climbers, mainly eating some plants, and because of the need to hibernate, North American black bears will always find a lot of food storage in spring and summer with good weather. So that in the winter a big meal. The hibernation of black bears is about 3-7 months.
Fourth, comparison of combat effectiveness
Polar bears are the largest and naturally the strongest, according to statistics, polar bears have a bite force of 960 pounds. The Asiatic black bear is 722 pounds and the American black bear is 598 pounds. At the same time, polar bears are born with hooks on their paws, which are five centimeters long, longer than black bears, and can firmly grasp the ice and prey. Although the claws of black bears are longer than polar bears, they are not as sharp as polar bears.
When polar bears swing their forearms, combined with their large claws, they will deliver a fatal blow to the enemy.
5. Personality
We may have seen news about bears attacking humans on the Internet, in fact, many pictures are Zhang Guan Li Dai does not say, bears will not take the initiative to attack humans, sometimes just want to find food, so they strayed into the human living environment. Polar bears are usually quiet and have very intelligent heads. And the Asian black bear seems timid and mild. But now they also sometimes show a certain aggressiveness, especially when their territory is invaded, they will not endure.
The lifespan of these bears is only about 20-30 years, but now they are facing a severe reality test, that is, whether polar bears or black bears, with global warming, the ice in the Arctic Ocean is melting faster and faster, and the living environment of polar bears is under great threat. While humans ruthlessly hunt and cut down a large number of forest trees, black bears gradually have nowhere to hide, and gradually become an endangered species. The number of Asian black bears on the mainland is now less than 50,000, and it has been listed as endangered and protected by us. It is a national second-class protected animal. It's time to protect them.
