How to classify common animals and how to classify the types of animals

The animal kingdom can be divided into the following 34 phyla:

Protozoa, Mesozoa, pores, discs, cnidarians, ctenophorae, flattenes, flattens, neomorphoses, jaws, rotifers, ventral hairys, mustalts, nematodes, nematodes, nematodes, gill drags, echinocephates, endoanal animals, armoured animals;

Annelida, Anatrida, Astral Insects, Brachizoa, Brachiozoa, Brachizoa, Tardigrades, Clawed Animals, Arthropoda, Molluscs, Brachiopods, External Anal Animals, Broom Animals, Trichognaths, Echinoderms, Hemichordates, Chordates.

6.Other animals.

Squid anemone sea urchin.

The types of animals are divided into vertebrates and invertebrates according to the presence or absence of vertebrates, and the types of vertebrates are divided into fish, amphibians, reptiles, birds, and lactating animals according to the presence or absence of vertebrates, and invertebrates are divided into:

Coelenterates, molluscs, arthropods, annelids, flattened animals, nematozoa, etc.

Vertebrata: Vertebral animals, a subphylum of chordates. The largest number, the most complex structure, and the highest evolutionary status, evolved from mollusks.

The morphological structure is very different from each other, and the lifestyles are very different. Vertebrates are generally symmetrical in shape, and the whole body is divided into three parts: head, trunk, and tail, with relatively complete sensory organs, motor organs, and a highly differentiated nervous system. It includes six categories: roundmouths, fish, amphibians, reptiles, birds and mammals.

Invertebrates are animals that do not have a vertebral column on the dorsal side, and they are the original form of animals. Its species account for 95% of the total number of animal species. It is distributed all over the world, and there are about 100 million species in existence.

Including protozoa, echinoderms, molluscs, flattened animals, annelids, coelenterates, arthropods, nematozoa, etc.

According to the external characteristics of animals, the ancient Zhou rites in China divided animals into five categories: hair, feathers, mediators, scales and wins, among which hairs and feathers are equivalent to beasts and birds in the current animal classification.

Modern biology classifies organisms according to their similarity and kinship. The proximity of the severance of the relationship can be based on the external morphology and internal structure of the animals, their distribution on the earth, and the main substances that make up their bodies, proteins and substances carrying genetic information, and the molecular structure of nucleic acids.

According to the degree of similarity and distant kinship of organisms, biology usually divides organisms into seven different levels, arranged in order from largest to smallest, they are kingdoms, phyla, classes, orders, families, generas, and species. This classification not only allows the complex and diverse organisms to form a very complete phyletic system.
