What are the common beasts in nature?
Abstract: Compared with animals, human strength and sensitivity are really insignificant, especially compared with some wild animals. So what are the common beasts? Lions and tigers naturally come to mind first, as well as leopards, bears, lynxes, wolves, rhinoceroses, wild boar, hyenas and so on. Let's walk into the fierce animal world with Bian Xiao and see those beasts who dominate one side! Introduction of tiger

Tiger, big cat; The coat is light yellow or brownish yellow and covered with black stripes; Round head, short ears, black behind the ears and a white spot in the center. Strong limbs; The tail is thick and long, with black rings and black tail.

Tigers are typical mountain animals, which can survive well from tropical rain forests and evergreen broad-leaved forests in the south to deciduous broad-leaved forests and mixed coniferous and broad-leaved forests in the north. In the northeast of China, it often appears in mountainous areas, such as ridges, bushes, rock or gravel ponds, etc. In order to hunt.

Tigers often act alone, and only in the breeding season do males and females live together. There are no fixed nests, and most of them wander in the mountains for food. Can swim, not good at climbing trees. Due to the development of forest areas and the surge of population, remote areas have developed into villages and towns in the past, and tigers often forage near forest settlements. Tigers are more active at dusk, more dormant during the day and rarely come out without being disturbed. Tigers have a wide range of activities, and their daily foraging activities can reach dozens of kilometers in the north; In Xishuangbanna, south of China, there is more food, so the moving distance is shorter.

The estrus mating period is generally from June 1 1 day to February of the following year. In estrus, the tiger's cry is particularly loud and can spread to 2 kilometers away. The gestation period is about 105 days, and each time, 1-5 cubs are born, usually 2 cubs. The newborn tiger cubs weigh about 1 kg, and they are breast-fed for 5-6 months. During this period, the tigress did not mate in estrus, so under natural conditions, the tigress can only reproduce once every 2-3 years. The female tiger is sexually mature at the age of 3, and the male tiger is later. The life span of a tiger is generally 20-25 years.

It is the smallest and most common bear in North America. Living in the forests of North America and Mexico. It is an expert in climbing trees. It often wanders around and sometimes attacks livestock. They usually don't attack humans unless they are provoked. American black bears are distributed in the forests of Canada and the central and eastern United States. It has many body colors, including black, brown, gray and white. American black bears often "get married and have children" from June to July, but after the bear's first birthday, the family will go their separate ways, and the father and mother bear will live apart, which looks like "divorce". But in June and July of the following year, they will remarry and reconsider giving birth to the next generation.

It can smell the smell half a kilometer away and hear footsteps 300 steps away. Although it looks silly, it is actually alert. Usually, black bears eat plants (you must have heard the story of black blind people breaking corn), but in autumn, they eat animal food such as insects and store a lot of fat in their bodies to hibernate in tree holes. His specialty is climbing trees and swimming. Because of my bad eyes, I have developed the ability to move freely day and night. Asian black bears are distributed in China, Indian, Russian, Japanese, Mongolian and other countries.

Its lower lip is long and active, shaped like a tongue and has no upper teeth. Its mouth can reach into the gap where insects hide and sweep prey into its mouth like a vacuum cleaner. Lazy bears have poor eyesight and rely on their sense of smell and hearing, so they choose to attack at night and sleep deeply during the day, so they are called lazy bears. Little lazy bears often come and go on the back of the mother bear, and their feet never leave their bodies. This mother-child relationship is much stronger than other bears.

8.polar bear

Also known as White Bear and Iceberg Big Mac, he is good at swimming. The head is small and the neck is long, and the hair is milky white. Although its body is very big, it is very agile and usually preys on animals such as fish, seals and walruses. Polar bears, distributed in the Arctic, are Eskimos' favorite prey. Because hunters all over the world hunt a lot, there is not much left. They live on the vast ice sheet in the Arctic. They are big and fierce, and live by hunting seals, walruses, whales, seabirds and fish. This seemingly bulky polar bear is so agile that it can even catch up with reindeer or arctic rabbits in a sprint. At the same time, it is also a master of ice swimming, swimming at a speed of 10 km, diving for 2 minutes and swimming for hundreds of kilometers in ice water, so it can be called a "semi-aquatic animal". Polar bears are the most carnivorous bears living in the northernmost part.

There are obvious skin folds on the body, and there are many small drums like round nails on the skin, which seems to be covered with a thick layer of armor. However, the skin between the skin folds is very delicate and easy to be bitten by mosquitoes, so you should take a mud bath almost every day to remove and prevent mosquito bites. The body length is 2. 1-4.2m, the tail length is 60-75cm, the shoulder height is 1. 1-2m, and it weighs 2-4 tons.
