What are the sounds of animals, namely, woof, hum, Cleisthenes, croak, baa baa, meow and goo goo?

Wang Wang, Buzz, Cleisthenes, Quack, Bae Bae, Meow Meow and Goo Goo respectively simulate the sounds of dogs, bees, cows, frogs, sheep, cats and pigeons.

First, the dog:

Dogs belong to Chordata, Vertebrate, Mammalia, Orthoptera, Carnivora, Schipoda and Canidae. Chinese is also called "dog", and dogs are distributed all over the world. Dogs, horses, cows, sheep, pigs and chickens are also called "six animals".

Some scientists believe that dogs were domesticated by early humans from gray wolves. The domestication time was from 40,000 years ago to 1.5 million years ago, and it has developed to this day. Known as "the most loyal friend of mankind", it is the pet with the highest feeding rate at present. Its life span is about ten years.

Second, bees:

Bees/bees are an important group of HYMENOPTERA, belonging to HYMENOPTERA, LEPIDOPTERA, Spoturopoda, Aphidea and Apidae in insect taxonomy.

Many species of Meliaceae have great economic value and are closely related to human life. Many kinds of products or behaviors are closely related to medicine (such as honey, royal jelly and bee venom), agriculture (such as crop pollination) and industry (such as beeswax and propolis). They are called resource insects.

The most familiar ones are Italian bees and oriental bees, which are domesticated artificially to make honey.

Third, cattle:

Cattle (Latin name: cattle) belong to Bovine, belonging to Bovine subfamily. Bison with chromosome number 56, yellow cattle with chromosome number 60 and Daniel with chromosome number 58 have fertile offspring, and they are mammals, which are prone to robertsonian translocation (centromere fusion) to change the chromosome number and reduce the fertilization rate.

Herbivorous, some species are domestic animals (including domestic cattle, yellow cattle, buffaloes and yaks). The body is stout, and some bull heads have diagonal lines. Cattle can help human beings in agricultural production.

Fourth, the frog:

Frogs, amphibians and Ranidae are collectively called Anura. Adults are basically tailless, eggs are generally produced in water, hatch into tadpoles, and breathe through gills. After metamorphosis, adults mainly breathe through the lungs, but most skin also has some breathing function.

Frogs in the north are commonly known as Daqingguai, formerly known as frog, green chicken, sitting fish, flounder and black frog. They are wild animals protected by the state, and everyone knows them from children to the elderly. Its population is widely distributed in the plains, hills and mountains of China, but the frog produced in the north has the best individual quality.

Five, sheep:

Sheep is the collective name of sheep subfamily, including mammals, Artiodactyla, cattle and sheep subfamily, and it is one of human livestock. Hairy quadruped ruminant, the main source of wool. The coat color is mainly white. Goats and sheep are mainly raised in China.

Sheep are also called sheep or white sheep. Hairy quadruped ruminant. Originally a product of mountains in the northern hemisphere, it is related to goats; The difference is that the body is fatter, plump and thick. Short head. Males have huge spiral horns, females have no horns or only small horns.

Mammals and ruminants generally have a diagonal line on their heads, and there are many varieties, such as sheep, lake sheep, goat and rock sheep.

Six, cats:

Cats, belonging to cats, are divided into domestic cats and wild cats, and are widely used pets in families all over the world. The ancestor of the domestic cat speculated that it was a kind of desert cat, Persian cat, which originated in ancient Egypt. It has been domesticated by human beings for 3500 years (but not completely domesticated like dogs).

Ordinary cats: round head, short face, five fingers on the forelimbs, four toes on the hind limbs, and sharp and curved claws on the toes, which can be extended. Night activities.

Seven, pigeons:

Pigeon is a very common bird, which is widely raised all over the world. Pigeons are the floorboard of hundreds of kinds of pigeons. The pigeon we usually talk about is just a kind of pigeon, which is a domestic pigeon. The most common domestic pigeon is carrier pigeon, which is mainly used for communication and competition.

Pigeons have lived with humans for thousands of years. The first pigeon image discovered by archaeologists came from Mesopotamia in 3000 BC, which is now Iraq.

Extended data:

Many animals make all kinds of sounds, which gradually evolve into the signal of communication between animals-animal language.

For example, crickets can express their "feelings" through the crisp and beautiful sound like music made by the friction of their wings. When men and women get along, the tone is very calm, just like lovers whispering; When alone, it will emit high notes to attract friends.

The researchers found that whenever the enemy came to the termite nest, the whole group of termites often fled without a trace, leaving only an empty city. In order to solve this mystery, entomologists have conducted special research; It turns out that termites acting as sentries can send out a "report" on the enemy's situation from far away, tap the cave wall with their heads and inform the ant colony in the nest to retreat immediately.

Bees on the hive

In nature, many animals communicate with each other by sound. Many birds have sweet and changeable sounds. They are excellent singers. It is said that there are two or three thousand bird languages in the world, which are comparable to human languages.

Some zoologists have studied various languages of birds and compiled a dictionary of bird languages. This dictionary is very useful. For example, the birds in the air are a great threat to the plane, because although they are small, they can pierce the plane like bullets and crash it.

Some airports have set up bird broadcasting stations to broadcast the frightened calls of birds in order to disperse them and make the plane take off and land safely.

The sound language of animals is ever-changing and has different meanings. The long-tailed rat will make a series of sounds when it finds strong enemies on the ground, such as foxes and wolves. If the threat comes from the air, its voice will be monotonous and lengthy; Once the Snitch lands on the ground, it will give an alarm every eight seconds.

Hens can call the police with seven different sounds. Her companions knew at will who the attackers were, where they came from and how far they were from here.

At present, taxonomists are studying the sound signals of animals as indicators of animal classification; Ecologists are exploring how to reveal the mystery of animal behavior through sound signals.

What is more striking is to use animal voice language to command animals and make them act according to human orders. For example, do not cross the set area boundary.
