China/Chinese alligator

It belongs to reptiles, also known as catfish.

Alias Eriocheir sinensis, Longtu and Zhupolong belong to Eriocheir sinensis, and the scientific name is alligator sinensis.

The total length of an adult fish can reach about 2 meters, and the tail length is similar to the body length. The head is flat, the nose and mouth are long, and the external nostril is located in the nose and mouth with a flap. The body is covered with a piece of leather armor, and the abdominal armor is soft; The nail plates are nearly rectangular and neatly arranged; There are two rows of nail plates protruding to form two ridges running through the whole body. The limbs are short and thick, with webbed toes and claws. The back of the body is grayish brown, the front of the abdomen is gray, and it is grayish yellow from the anus to the back. Flat tail. Newborn crocodiles are black with yellow stripes.

He lives by digging holes in rivers and lakes, and he is fierce, feeding on all kinds of mammals, birds, reptiles, amphibians and crustaceans. Mating in June, laying eggs in July and August, each nest can lay more than 20 eggs. The eggs are laid in the grass, covered with weeds, and the female crocodiles stay by and hatch at natural temperature. The incubation period is about 60 days. Have the habit of hibernating.

Produced at the junction of Anhui, Zhejiang and Jiangsu. Chinese alligator is a unique relic species in China, which has many physiological characteristics, and the discontinuity of distribution also illustrates this point. In order to explore the mystery of the Chinese alligator, China established the Chinese alligator reserve and the Chinese alligator breeding research center.

It belongs to the national first-class protected animals.

salamander

Amphibia, also known as giant salamander, is the largest amphibian in the world. It is endemic to China, inhabits mountain streams, moves at night, preys on fish, shrimp and insects, and is fertilized in vitro. It is widely distributed in China, mainly in Central China and South China. Crying baby

The giant salamander, also known as the giant salamander, belongs to the amphioxus family, and its scientific name is giant salamander.

The giant salamander is the largest species in the existing order, and its longest can exceed 1 m. The head is flat and blunt, the mouth is big, the eyes are underdeveloped, and there are no eyelids. The front of the body is flat, and the tail gradually turns to the side. There are obvious skin folds on both sides of the body, short and flat limbs, and slightly webbed fingers and toes. The tail is round and has fins up and down. The body surface is smooth and covered with mucus. The back of the body is mixed with brown and red, and the ventral color is lighter.

Giant salamanders live in clear streams in mountainous areas, generally hiding in the gaps of mountain streams, and the caves are below the water surface. Laying eggs in July-August every year, with more than 300 eggs per tail. Male salamanders wrap their eggs on their backs and hatch after 2-3 weeks.

Giant salamander is an endemic species in China, and it is commonly called "giant salamander" because its cry is like a baby crying. The heart structure of giant salamander is special, and some reptilian characteristics have appeared, which has important research value. Because the meat is delicious, it is regarded as a treasure and has been killed. Resources have been severely damaged and need to be protected.

Giant salamanders are mainly produced in North China, Central China, South China and Southwest China. I also occasionally see it in our city. Its individual is not big, and it is often mistaken for an ordinary fish. In the summer of 200 1 year, a giant salamander only a few centimeters long was found by the public and sold at a stall in Xikou town of our city. After the purchase, it was sent to the relevant departments for signature, and now it is kept in the water hall of Tengtou Village.

The giant salamander belongs to the national second-class protected animal.

golden monkey

Primates, with long golden hair on their shoulders, live in 3000-meter alpine forests, live in arboreal groups and feed on wild fruits, buds and bamboo shoots. They are rare monkeys in China.

The scientific name of golden monkey is Rhinopithecus roxellanae, and the English name is snub-nosed monkey/golden monkey. Golden monkey is an endemic animal in China, which belongs to the national first-class protected animal. China golden monkeys include Sichuan, Yunnan and Guizhou. Yunnan golden monkeys live in the snow-capped mountains and fir forests in remote Yunnan and Tibet, with only one thousand in number. Guizhou golden monkey only exists in Fan Jing, Guizhou, and the number is only over 700. Everyone is familiar with Sichuan golden monkey. Sichuan golden monkey, distributed in Sichuan, Shaanxi, Hubei and Gansu, lives in the deep mountains, in groups, with golden cloaks on their backs, climbing trees, jumping and prancing. The golden monkey has been rented abroad for many times, which has achieved good exhibition effect and great sensation effect.

White fin dolphin

Mammals inhabit Dongting Lake and the middle and lower reaches of the Yangtze River. During the flood season, the water level rises, swarms swim into Dongting Lake and its vicinity to breed, and the water level drops back to the Yangtze River, mostly in the deep layer. At dawn and dusk, it preys on fish near shallow water and is on the verge of extinction.

White-fin dolphin is commonly known as white fin, white clip and hippo. It belongs to mammals, cetaceans and baiji. Its distribution is limited to the middle and lower reaches of the Yangtze River, especially in the Yangtze River section of Hunan, Hubei, Anhui and Jiangsu below Shashi, Hubei.

Baiji dolphin is a rare aquatic mammal endemic to China. It is a valuable material for studying cetacean evolution and biological evolution. It has a developed brain and is an intelligent animal. It has special functions such as "echolocation" and sonar. Streamlined figure, rich subcutaneous fat and fast swimming, these structures have important scientific value in bionics.

Baiji dolphin is spindle-shaped. The snout is extremely long and narrow, and the maxilla and mandible are almost the same length and slightly upturned. The body length is six times that of a kiss. Body color: the back is bluish gray and the abdomen is white. There are semicircular white wide lines on both sides of the neck, behind the ear hole and above the flippers, and there are two half-moon white wide lines on the tail side above the anus.

Baiji dolphins like to move in the mainstream areas of rivers far from the shore, and belong to hydrophobic dolphins. There is a habit of clustering in action, often moving in the middle of the river in groups of three or five, and occasionally entering the confluence of lakes, tributaries and the main stream of the Yangtze River. Baiji dolphin breathes with its lungs and comes out of the water for air every minute or two. When breathing, the head always comes out of the water first, sometimes spraying water, and making a sound when breathing out of the water. The weather is sultry, and when the rainstorm comes, it will come out of the water frequently and fall together. The masses call it "Baiji Dolphin Worship River".

Baiji dolphin is a carnivore with poor eyesight. It finds food through its own ultrasonic signal and then suddenly swallows it. Their feeding habits are mainly fish, and they often feed in shallows, bifurcated streams and tributaries. Its food intake is very large, and the general food intake can account for 10% ~ 12% of the body weight.

The female is 6 years old and the male is 4 years old. The reproductive mating period is from April to June, the pregnancy is about 9 months, and the baby is delivered in the river in February of the following year. Female dolphins only give birth to 1 baby every year, each baby 1 baby, and occasionally give birth to twins. Newborn dolphins grow up by feeding their mothers' milk and act with the group.

Great changes have taken place in the ecological environment of the Yangtze River after the completion of Gezhouba and Three Gorges Dam. The development of shipping industry, river regulation, the increase of motorboats, water pollution, siltation of rivers and lakes, the use of harmful fishing gear and harmful fishing methods, etc. , a serious threat to the ethnic continuation of the baiji dolphin. According to the measured statistics, the resources of Yangtze baiji dolphin are insufficient 100, far less than the national treasure giant panda. In order to prevent the extinction of the baiji in nature, the state has listed it as a first-class protected animal, and designated the Swan Island Ancient Road in the Yangtze River and Tongling section in Anhui Province as nature reserves to protect and multiply baiji resources and save endangered species.

Siberian tiger

Also known as Siberian tiger, it is an endangered species in the world, mainly distributed in northeast China and Siberia. Due to excessive deforestation in China, the ecological environment on which Siberian tigers depend for survival has been seriously damaged, and the population number has dropped sharply. According to the recent field investigation by the international joint investigation team, the number of wild Siberian tigers in China is less than 20.

In nature, many animals have a set of organs with special functions to adapt to different living environments.

Spider-Hydraulic Legs A spider has four pairs of legs in its head and chest. Its legs are strange. They are not muscles, but liquids. Therefore, when it walks, it depends on the sharp increase or decrease of the liquid pressure in its legs. This is a rare and unique movement in the animal kingdom-hydraulic transmission.

Polar bear-photoelectric cell is known as "the king on ice". Its hair is a hollow tube, but it is actually a tiny photoelectric tube. Only ultraviolet light can pass through the hole in the middle. Polar bears use "photovoltaic cells" to absorb ultraviolet rays from the sun, which raises the temperature around their bodies. Just like a fur coat that keeps warm automatically, with a rich fat layer, they can live carefree in the ice and snow.

Dolphin-sonar system The valve and airbag system in the dolphin's head can emit ultrasonic waves, which has the function of echolocation and is very accurate. Therefore, it can track and capture all kinds of targets flexibly and accurately in the ocean world with dark light and complex geological conditions.

Fireflies-Luminous cells The luminous organ of fireflies is located on the right side of the abdomen and consists of transparent epidermis, luminous tissue and reflective layer. Luminescent cells contain fluorescein and luciferase, and fluorescein is oxidized by luciferase and releases light energy. The "cold light" emitted by fireflies does not generate heat, so it is the safest lighting facility in mines where explosive substances are stored and inflammable and explosive gases such as carbon monoxide, hydrogen and methane are filled.

Seagull-seawater desalinator Seagull has a peculiar ability to desalinate seawater. It turns out that there is a salivary gland between its mouth and eyes, which can secrete saliva. This salivary gland is its "seawater desalinator". Humans are developing this bionic seawater desalination device.

Strange phenomena in animals

In nature, the bee kingdom has a strict "security system". All the year round, no matter day or night, the vigilant "sentry" is always at the door of the hive, and it is almost impossible for "outsiders" to sneak in.

There is an insect called "grimace moth". Its wings and abdomen are black and yellow, and its back has yellow and white stripes like grimace. It will imitate the "voice" of the young queen bee, which is like a spell for the bees to respect and obey. As a result, it can enter the hive without blowing off dust. Eat fragrant honey to your heart's content, and then leave the hive.

When studying the relationship between various animals in the forest, a biologist at a tropical research institute in Panama found that a small spider has a very strange relationship with Okumo: Okumo weaves a big web with strong spider silk, but this spider silk is not sticky. The little spider hangs one end of the net on the big net and the other end is attached to the body. Drosophila and other small insects fall into the net, which Okumo often fails to find, or thinks the prey is too small to care. However, the little spider caught the wind and jumped up quickly. It dragged the food onto the cobweb and wolfed it down. Sometimes, little spiders steal the prey that Okumo has wrapped in spider silk. At this time, they often climb to the center of Okumo's spider web, put on their own spider silk, and then run to the edge of the web to secretly pull food for themselves. Generally, these things are done when Okumo is away, and the spider often judges whether the owner of the food is there according to the vibration of the net.

A thief ant living in the grassland area of the former Soviet Union often builds its own nest near the red ant's nest, then digs some tiny passages leading directly to the red ant's nest, attacks the larvae and pupae of the red ant, and then has a full meal after being caught. Thief ants are very agile and will quickly get into small holes or cracks, and red ants can't do anything about it.

Strange animals that laugh.

There is a laughing bird living in the Australian forest, and the locals call it "Kukabala". This kind of bird is an expert in catching snakes. They have sharp mouths with hooks. When catching a snake, they first hold the snake in a tree with a hook, then throw the snake from the air and die, and then chew it slowly. They ate and laughed as if celebrating their victory.

There is also a bird in the coniferous forest of Sweden, which has more than ten feather fans, forming more than ten pieces. When they fly, the air violently impacts the film on the fan, and the film will make a loud, cheerful and "laughing" sound.
