At present, there are five main types of rhinos in the world: two types in Africa - black rhino and white rhino; There are three groups in Asia – Sumatran rhino, Javan rhino, and Indian rhino.
White rhinoceros. The white rhinoceros, also known as the square-billed rhinoceros, is not white, but the same color as the black rhinoceros, with its most striking external feature being its square beak and horns averaging 60 centimeters and reaching up to 200 centimeters long. The body size is the largest of the 5 rhinoceros, with females weighing about 1,800 kg and males weighing 2,300 kg.
Black rhinoceros. The black rhinoceros is also called the sharp-nosed rhino, and the obvious characteristics of the black rhinoceros are that the upper layer is coiled, the body color is gray, dark yellow-brown, and the rolling in the soil is dyed gray-black, and the horns can reach up to one meter.
Indian rhino. The Indian rhinoceros, also known as the one-horned rhinoceros and the large one-horned rhinoceros, both male and female rhinoceroses have a horn at the end of their noses, which is black, conical, thick but not long, and about 30 40 cm long. The ** on the body is like armor, hard and black, dark gray with purple, with rivet-like small nodules attached to it; in the shoulder blades.
There are wide folds at the lower neck and at the joints of the limbs. It is larger in size and is second only to the white rhinoceros. The Indian rhino is found in northern India and Nepal and is currently the most abundant rhinoceros in Asia.
Javan rhinoceros The Javan rhino, also known as the small one-horned rhinoceros, is very similar in appearance to the Indian rhinoceros, but it is slightly smaller and gray. The male rhino has one horn, the female rhino has no horns, and the horns are smaller, with a horn length of less than 25 cm. Adult Javan rhinos can weigh tons and grow up to 3 meters long, due to the low birth rate, the number of Javan rhinos is decreasing, and there are currently less than 60 Javan rhinos left in the wild in the world, most of which inhabit the Majung Gekurong National Park in Indonesia.
Sumatran rhino.
The Sumatran rhino, also known as the two-horned rhinoceros, is a descendant of the first woolly rhinoceros on Earth and is the smallest and only hairy rhinoceros in existence. Both male and female beasts have double horns on their noses, with long anterior horns and short posterior horns. Like the Javan rhino, it was originally distributed in a large area of Southeast Asia, and now it is more sporadic in distribution, but it is still more widespread than the Javan rhinoceros, and the number is slightly larger, and there are hundreds of individuals.

The rhinoceros has a number of distinctive physical features: an unusually large body, short column-like limbs, a large head, thick armor-like skin, a snout with one or two horns, and a pair of small eyes on either side of the head. Despite their large bodies (the white rhinoceros is the second largest continent after elephants) and ugly in appearance, they are timid and harmless creatures, and generally prefer to hide rather than fight.
However, they are ferocious when injured or in trouble, and often blindly charge at their enemies. Despite their bulky size, they are still able to walk or run at a fairly fast pace. The African black rhino can reach speeds of up to 45 kilometers per hour over short distances.
Javan rhinoceros (Rhinoceros sondaicus).
Also known as the small one-horned rhinoceros, it is native to India, and now only the island of Java remains. It belongs to the same genus as the Indian rhino and has similar living habits to the Indian rhino. There are only about 50 of them left in the world, all of which live in protected areas at the western tip of Java and are the rarest species of rhinoceros.
Sumatranero (Didermocerus sumatrensis).
The Sumatran rhino, also known as the Asian two-horned rhino, is the smallest of the five species of rhinoceros. It is also the only species of rhinoceros with hair on its body. It is native to India, Indochina, Indonesia, Sumatra and Kalimantan. It now only exists in Sumatra, Malaysia, Myanmar and Thailand.
Generally, the body length is meters, the shoulder height is meters, and the weight is about 1 ton. It is the only Asian rhinoceros with two horns, so it is easy to distinguish. They used to live in open areas, but now they live mainly in dense jungles near water sources.
Early morning and evening they eat leaves, twigs, bamboo shoots, and occasionally fruits. For each litter, the gestation period is said to be 7-8 months.
Both the black and white rhinos in Africa have a lead-gray complexion, while the white rhinos are slightly whiter.
Black rhinoceros (Diceros bicornis).
Also known as the rhino, it is the most widely distributed and extant species, reaching between 10,000 and 20,000 individuals. It is now produced in eastern and southern Africa. Inhabits jungle areas. The body length is meters, the tail length is about 70 centimeters, the shoulder height is meters, and the weight is tons. Eat mainly leaves
The black rhinoceros has a reputation for having a bad temper, and while it may be exaggerated, it does have an unpredictable temper and sometimes attacks vehicles, people, and campfires. Short runs can reach speeds of up to 45 kilometers per hour. It breeds throughout the year, with a gestation period of 438-469 days.
White rhinoceros (ceratotherium simum).
Also known as the rhinoceros, it is the second largest continental animal after elephants. Body length meters, shoulder height meters, weight tons. It is produced in Zaire, Sudan, Kenya and Uganda.
It inhabits grasslands and jungles, and is herbivorous and low shrubs. It is more gregarious than the black rhino, in pairs or families only together. It breeds throughout the year and has a gestation period of about 17-18 months.
There are about 4,000 of them in the world.

The white rhinoceros, also known as the rhinoceros, is the second largest continental animal after elephants and the most evolved of the existing rhinoceros. Body length meters, shoulder height meters, weight tons. Because white rhinos like to eat grass, their beaks have become very flattened like those of horses.
Weighing 4,000 pounds and with only one horn on its snout, the Indian rhinoceros is the largest single-horned rhinoceros in the world. Indian rhinos don't have very long horns, and they usually run at speeds of up to 28 miles when threatened, but they use a few inches of fangs in their jaws to bite each other when courting. The skin of the Indian rhinoceros is thick and very large, with several layers of wrinkles, but they are quite sensitive, so they will regularly go to the mud to remove the parasites on it.
The black rhino, also known as the barramundi rhino, is now found in eastern and southern Africa. Inhabits jungle areas. The body length is meters, the tail length is about 70 centimeters, the shoulder height is meters, and the weight is tons.
The black rhinoceros prefers to live in the bushes and live alone, living on small branches and leaves. The beak of the black rhinoceros is specialized into a snout suitable for breaking branches.
The Javan rhinoceros belongs to the family Rhinoceros of the order Oddhoofidae and is a close relative of the Indian rhinoceros. Today it is only found on the Indonesian island of Java. The Javan rhino is smaller than the Indian rhino :
The whole body is long meters, the shoulder height is meters, the average weight is 1500 kg, and the largest individual can reach 2300 kg. There is a horn, the horn is less than 20 cm long, ** gray. The only species of the genus Rhinoceros in Sumatra, the Rhinoceros genus, is the smallest living rhinoceros.
The body length is 240-315 cm, the weight is 550-1100 kg, the average weight is only 700 kg, and the largest individual is 1100 kg. It is covered with thick reddish-brown hair.

There are no rhinos in China today.
The Chinese rhinoceros is a collective name for the populations of three species of rhinoceros (Indian rhinoceros, Sumatra rhino and Javan rhinoceros) that once grew in China, generally with a body length of meters, a height of meters, and a weight of 1 ton, which was once widely distributed in central and southern China of China, inhabiting the forest edge mountainous areas close to water sources. Most of the Chinese rhinoceros are hard and black, dark gray with purple tinge, with small rivet-like nodules attached to them; There are wide folds on the shoulder blades, under the neck, and at the joints of the limbs, making the body look like it is wearing a piece of armor.
Due to human activities and overexploitation, the habitat of rhinos is decreasing year by year; Coupled with the extremely high economic value of their head rhino horns, they have been hunted by humans since ancient times, and the number of kills is larger and larger the closer to modern times, in this way, they finally disappeared in China at the beginning of the 20th century, and completely disappeared in China in 1922.

There are no rhinos left in China, and the last rhinoceros in China became extinct in 1972 due to human hunting.
The extant 4 genera and 5 species of rhinoceros are all endangered except for the white rhinoceros, among which the Javan rhinoceros has the smallest number, about 50 individuals. There are only about 10,000 to 30,000 black rhinos. These rhinos, which inhabit Asia and Africa, face the threat of habitat destruction, buyers of rhino horn in East Asia, and hunters from Europe and the United States.

Rhinos have very few natural predators in nature – but humans and other rhinos pose a great threat to it. Its horns, its thick ** and its huge body are the ** of defense. The Indian rhinoceros has a rough, wrinkled** that can protect itself like armor.
There are dozens of phyla of marine animals, which can be divided into two categories: marine invertebrates and marine vertebrates, or three categories: marine invertebrates, marine protochordates and marine vertebrates.
Conditions for the formation of fog.
One is cooling, the second is humidification, and the third is condensation nuclei to increase the water vapor content. A kind of fog is formed by radiative cooling, mostly in the night and early morning when it is clear, breezy, and the water vapor near the ground is relatively abundant and stable, or there is a temperature inversion, which is called radiant fog in meteorology; The other is the fog formed by the horizontal movement of warm and moist air, passing through the cold ground or water surface, and the water vapor in the air is gradually liquefied by cold, which is called advection fog in meteorology; Sometimes fog formed by both causes is called mixed fog. It can be seen that these conditions can be met in late autumn and early winter, especially in the morning of late autumn and early winter. >>>More
The steel plate used in the automobile body is mainly the steel plate for the body of the body, and the thickness of the cold-rolled and hot-rolled thin steel surface treated steel plate and high-tensile steel plate materials are mainly used, and many accessories for decoration use stainless steel plates. There are two types of steel plates used in the hot-rolled and cold-rolled steel plate industry: one is the steel plate made after high-temperature rolling, which is called hot-rolled steel plate; The other is the hot-rolled steel plate after frequent warm rolling and surface quenching and tempering treatment, which is called cold-rolled steel or polished steel plate. >>>More
1. Fireproof board.
The fireproof board door panel is the door panel material currently used, its color is relatively bright, the edge sealing form is diverse, with wear resistance, high temperature resistance, scratch resistance, penetration resistance, easy to clean, moisture-proof, non-fading, delicate touch, affordable and other advantages.
