Regarding the discovery of animals, how many species of animals have been found by humans

According to the visual principle of frog eyes, people have successfully developed an electronic frog eye. This electronic frog eye can identify objects of a specific shape with the same accuracy as a real frog eye. After the electronic frog eye is installed in the radar system, the anti-jamming ability of the radar is greatly improved.

This radar system can quickly and accurately identify specific shapes of aircraft, ships, missiles, etc. In particular, it can distinguish between real and fake missiles and prevent the real from being confused with the real.

Electronic frog eyes are also widely used in airports and traffic arteries. At the airport, it can monitor the take-off and landing of aircraft, and can issue an alarm if it detects that the aircraft is about to collide. In the traffic arteries, it can direct the driving of vehicles and prevent the occurrence of vehicle collisions.

<> "The white-spotted pufferfish is a new species of puffer fish discovered by scientists in 1995, after people had experienced a decade-long period of time and seclusion to explore the "crop circle" on the seabed. The culprit behind this bizarre pattern was the small, delicate white-spotted pufferfish.

The Tabanuri orangutan was recently spotted as an ape in Sumatra. There are only about 800 Tabanuri orangutans in the wild, which may not have been around for long, and are now critically endangered.

The okapi, a curious animal found in the Congolese rainforest, was only discovered at the beginning of the last century and disappeared for more than 50 years. With zebra stripes and a giraffe's slender tongue, they sleep only five minutes a day. At present, due to the extremely scarce number of okapi in the wild, the status of okapi in the world is quite high, and there is no place in the whole of Asia, only the Tokyo Zoo in Japan can see okapi.

The primeval snail fish, a fish found in the deepest part of the world's oceans, lives in the deep sea at more than 8,000 meters, and scientists speculate that 8,200 meters is the physiological limit of all fish, and almost no fish can survive in this environment.

The Southern-Central Oryx, considered one of the most astonishing species discoveries of the twentieth century, was first spotted in the Annam Mountains of Vietnam in 1992. The remaining wild population is very scarce and is on the verge of extinction.

<> "Leaf-tailed geckos, now found in Cape Melville, Australia, are nature's masters of camouflage, their body surface is like a dead leaf, it is difficult to identify, and even the tail has gradually formed a flattened and curly shape in the process of evolution.

The Tabanuri orangutan, a new species of orangutan discovered in recent times, is now distributed in the rainforests of Sumatra, with just over 800 individuals, and is on the verge of extinction.

The giant stick insect is a novel stick insect animal discovered in modern China, this insect is the longest in the world, with a foot of centimeters, more than more than 800,000 species of insects. And in 2017, it was certified by the Guinness Book of World Records. Nowadays, it is mainly distributed in the Dayao Mountains of Guangxi.

The white-spotted pufferfish, one of the top 10 novelties of modern times, was discovered by scientists over a decade of research. White-spotted puffer dolphins draw intricate patterns in the riverbed of the seabed during courtship, and later scientists discovered that this pattern is a nest used to attract eggs of the opposite sex.

The Komodo dragon, a new type of monitor lizard discovered at the beginning of the last century, is currently the largest lizard known to man, and only fewer than 3,000 Komodo dragons survive in Indonesia. Despite its rarity, this animal is a top predator in the region, and it is said that an adult monitor lizard is capable of catching prey several times its size.

According to zoologists, there are about 1.5 million known species of animals on Earth.

Animals can be divided into two categories: vertebrates and invertebrates, vertebrates have a vertebral column composed of many vertebrae on the back of the body, and the individual is generally larger; Invertebrates have no vertebral columns, and most of them are small, but they are diverse, accounting for more than 90 of the entire animal population. For example, insects such as flies, mosquitoes, grasshoppers, butterflies, etc., are invertebrates. Vertebrates can be divided into five major groups: fish, amphibians, reptiles, birds and mammals.

Fish are the largest group of vertebrates, with a total of 25,000 to 30,000 species including marine fish and freshwater fish, such as carp and yellow croaker. There are more than 2,000 species of amphibians, such as frogs. There are more than 3,000 species of reptiles, such as snakes, turtles, crocodiles, etc.

There are 9,000 species of birds, such as pigeons, sparrows. There are more than 4,500 species of mammals, such as horses, cows, lions, tigers, etc. There are still many species of animals in the world that have not yet been discovered.

There are about fifteen million species of animals in the world! Recent studies suggest that there may be 10 million species of insects worldwide, accounting for about half of all living species on Earth. However, there are only 1 million species of insects with names and surnames, accounting for 2 3-3 4

It can be seen that there are still 90% of the species of insects in the world that we do not know; According to the most conservative estimates, there are at least 3 million species of insects in the world, and there are still 2 million species to be discovered, described and named. Approximately 1,000 new species of insects are published each year in the world, and they are included in the Zoological Record, making the journal a must-consult search tool for researchers working on animal taxonomy.

Among the named insects, there are as many as 350,000 species of Coleoptera (beetles), of which the weevils are the largest, including more than 60,000 species, which is 10 times that of mammals. Lepidoptera (butterflies and moths) are next with about 200,000 species. There are about 150,000 species of Hymenoptera (bees, ants) and Diptera (mosquitoes, flies).

The figure below shows the relative number of known species of different taxa in the kingdom Animalia.

Not only are there many species of insects, but there are also many individuals of the same species, some of which are surprisingly large. An ant colony can have up to 500,000 individuals. A tree can contain up to 100,000 individual aphids.

In forests, there can be 100,000 springtail insects per square meter. When locusts occur in large numbers, the number of individuals can reach as much as 71.2 billion, the total weight is about 1,250,300 tons, and the area covered by swarms can reach 500,1,200 hectares.

(1) The rabbit uses the action of slapping the ground with its legs to convey information, and most of the rabbits who slap the ground with their hind legs are male rabbits, which is a way for it to express its emotions to female rabbits. (2) The largest monkey in the world is the baboon, and the smallest monkey is the marmoset. 3) When the dog is happy, it keeps wagging its tail.

When the dog is angry, it stretches its tail back. When the dog is panicked and frightened, it clamps its tail. 4) Leopards grind their claws on trees.

The stag rubs its horns against the trunk of a tree to sharpen the horns. Wild boars often grind their tusks in trees. 5) Polar bears wear thick white fur coats.

Seals and walruses have a thick layer of fat that keeps their bodies warm. 6)"Four is not like"Its real name is Elk, and it is a rare animal of our country.

Are these enough? Not enough yet.

Therefore, there are still many animals in the world that have not been studied in detail, and scientists estimate that there are more than 10 million species of animals that have not yet been discovered and studied by humans, which shows how rich and diverse the animal world is.
