What are the animals in the world 5, what are the animals in the world

The animal species in the world are:1. Reptiles: evolved from the ancient amphibians at the end of the Carboniferous period, the heart has two atria and two ventricles, the ventricles have incomplete diaphragms, and the body temperature is not constant, which is truly adapted to terrestrial life of ectothermic vertebrates, and thus produces constant temperature birds and mammals.

Reptiles are not only further adapted to terrestrial life in terms of adult structure, but also free from the constraints of water, and are called amniotes together with birds and mammals.

2. Birds: Birds feed on plant seeds, insects, voles or snakes, most of which are beneficial to humans. We need to protect the birds. Among them, there are migratory birds that are good at long-distance seasonal migration, and there are also resident birds that settle in small areas, which is a large group of animals in the animal kingdom.

3. Mammals: Most mammals are vertebrates with a whole body coat, fast movement, constant temperature viviparity, and diaphragm in the body, and are the most complex animal groups in the vertebrate body structure and functional behavior.

Animals are a class of organisms in nature, mainly including protozoa, sponges, coelenterates, flattened animals, nematozoa, annelids, molluscs, arthropods, echinoderms, and chordates, etc., about 1.3 million species. According to the latest definition of animal authority by zoo3, it is defined as an organism that cannot synthesize organic matter on its own, and must be nourished by animals, plants or microorganisms to carry out or sustain life activities.

Well, that's too big, isn't it? There are many types of light, such as mammals, reptiles, amphibians, and invertebrates

Dogs, cats, chickens, elephants, mosquitoes, snakes, ants, lions, spiders, bees, whales, pandas, chimpanzees, bats, pigs, crocodiles, mice, tigers, parrots, horses, cockroaches, dolphins, monkeys, sharks, turtles, cow octopus, fish, rabbits, flies, cicadas, giraffes, wolves, frogs, polar bears, butterflies, lizards.

Hamsters, snails, pigeons, sheep pythons, rhinos, goldfish, sparrows, owls.

Chameleon, chinchilla.

Penguins, foxes, cobras, zebra finch, pangolins, caribou, sea slugs, slugs, squid, camels, seahorses, kangaroos, etc.

An animal is a species of living organism. They generally feed on organic matter, can feel, can move, and are able to move autonomously. Something that is active or capable of moving. Including people.

According to fossil research, the first animals to appear on Earth originated from the ocean. After a long geological period, early marine animals gradually evolved into various branches, enriching the early life forms on earth. Prehistoric animals appeared before the advent of humans and flourished during their respective periods of activity.

Later, they became extinct one after another in a constantly changing environment. However, the animals on Earth continue to evolve and reproduce from the lower to the higher, from the simple to the complex, and have the diversity they have today.

Scientists divide the extant animals known to humans into two major types: invertebrates and vertebrates, according to the presence or absence of a vertebrate in their bodies.

Scientists have identified more than 46,900 species of vertebrates. Including carp, yellow croaker, grass carp and other fish animals, snakes, lizards and other reptiles, frogs, baby fish.

and other amphibians, birds as well as mammals such as red pandas.

Scientists have also discovered more than 1.3 million species of invertebrates. Most of these animals are insects, and most of the insects are beetles. Slugs, earthworms.

Squid, oysters, red starfish, jellyfish, spiders, polyps, radiolaria, roundworms, pork tapeworms, sand silkworms, snails, slugs.

and so on are invertebrates.

The bodies of all members of the animal kingdom are heterotrophic organisms made up of cells.

Kittens, puppies, elephants, lions, snails, ants, spiders, peacocks.

There are many species of animals in the world, including Javan rhinoceros, Far Eastern leopards, golden-headed monkeys, red foxes, lynxes, white tigers, South China tigers, hornbills, Chinese alligators, Asian elephants, and more.

1. Giant pandas.

As a national treasure of our country, the giant panda is certainly on the list. The giant panda, belonging to the carnivorous order, the bear family, the giant panda subfamily and the only mammal of the giant panda genus, has a black and white body color, it has round cheeks, fat limbs, small eyes, small ears, big dark circles, a chubby body, the iconic inner figure walking style, and also has scalpel-like sharp claws.

2. White Tiger. The white tiger belongs to the white variant of the Bengal tiger, the white tiger is very rare, due to the lack of protective color, the white tiger is very difficult to survive in nature and has become extinct in the wild. Today's white tigers are all bred in captivity. The color is different from that of the common Bengal tiger, with a pink snout, white to cream fur, and black, gray, or chocolate stripes.

3. Stallions. The stallion is a stallion with very good genes, and his body and appearance can be said to be perfect among horses, so he has been named "one of the most beautiful animals in the world".

4. Lynx. The lynx, also known as the horse lynx and the lynx, resembles a domestic cat but is much larger than a domestic cat, with a pinkish-brown or gray-brown body and inconspicuous hazel spots. The black towering tufts of hair at the tips of the ears and the long drooping hairs on the cheeks are the distinctive features of the lynx.

5. Red fox.

The red fox is rare in China, it has the elegant appearance of a fox, coupled with a red hair, it looks more eye-catching, beautiful and spiritual. This species of fox is mainly found in the northern hemisphere region.

Cats, dogs, sheep, rabbits, mice, tigers, cows, lions, pigs, hedgehogs, monkeys, sloths, snakes, geckos, lizards, turtles, turtles, crocodiles, alligators, turtles, chameleons, dolphins, pandas, wolves, deer, martens, tapirs, zebras, foxes, bears, elephants, leopards, musk oxen, koalas, lynxes, pangolins, anteaters, etc.

Look in the mirror and you can see the most advanced animals in the world.

A lot! But one of them is special! Smart though! But! In terms of love...!

Classification of animals altogether.

There are more than 350 orders in more than 70 classes in 35 phyla, including protozoa, porous animals, coelenterates, flattened animals, nematozoa, bryozoans, annelids, molluscs, arthropods, echinoderms, chordates, etc., and there are more than 1.5 million species known (see table), distributed in all oceans, land, including mountains, grasslands, deserts, forests, farmland, waters and poles on the earth, and become an inseparable part of the natural environment.

Due to the adaptability to the living environment, there are great differences in morphology and function according to different categories. In terms of individual size alone, protozoan lines are composed of single cells and are the lowest and most primitive group of animals; The blue whale among the chordates, which can reach a body length of 30 meters, is a rare behemoth in the world.

What animal is full, you ask? There are breastfeeding.

Canines. So much you ask which murmuring friend.
