The animal kingdom is divided into those phyla.
The animal kingdom is a system of biological taxonomy, and there are many kinds of them: they are very different and diverse. A lower-level unit of classification, called a "gate", has been added under the "boundary".
Taxonomists divide the animal kingdom into "phylum" according to the differences in morphology between species, the complexity or simplicity of the structure, and the high and low degree of evolution.
From lower to higher animals, the kingdom can be divided into 12 phyla: protozoa, pores, coelenterates, flattens, gardens, rings, arthropods, molluscs, molluscs, hairy-palatines, echinoderms, and chordates.
For example, snakes belong to the phylum Chordates, roundworms belong to the phylum Garden, earthworms belong to the phylum Ringworms, snails belong to the phylum Mollusca, bloodsuckers belong to the phylum Platyzoa, and insects, spiders, and centipedes belong to the phylum Arthropods.

There are 12 phyla in the animal kingdom, namely: Protozoa, Sponges, Coelenterates, and Molluscs.
An animal is a species of living organism. They generally feed on organic matter, can feel, can move, and are able to move autonomously or move. 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, animals on Earth continue to evolve and reproduce from the lowest 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 sharks, rays and other cartilaginous fish animals, carp, yellow croaker, grass carp and other bony fish animals, frogs, baby fish and other amphibians, snakes, lizards and other reptiles, chickens, pigeons, sparrows and other birds, monkeys, red pandas and other mammals.
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. Sponges, earthworms, squid, oysters, red starfish, jellyfish, spiders, polyps, radiolaria, roundworms, pork tapeworms, sand silkworms, snails, slugs, etc., are all invertebrates.
The bodies of all members of the animal kingdom are heterotrophic organisms made up of cells.

The animal kingdom can be divided into 10 phyla, namely: protozoa, sponges, coelenterates, molluscs, echinoderms, flattens, nematodes, annelids, arthropods, and chordates.
1. Protozoa.
All of them are single-celled animals, a few aggregate to form a group, live in water or wet soil, and some live parasitic, with asexual or sexual reproduction. There are no medicinal animal species in this phylum, but they are primitive groups in evolution, and they are also very closely related to human life, and some parasitic species can cause great harm to human health and the breeding of economic animals.
2. Sponge phylum.
Also known as porifera, it is the most primitive multicellular animal that lives in water, and although the cells are differentiated, they do not constitute tissues. The cells can be arranged in 2 layers, but do not differentiate into 2 germ layers, the inner and outer germ layers, and there is a system of ducts in the body that gets food from water, and bone needles to support and protect the body. Such as the brittle needle sponge sp0ngilla fragilis, which can be used medicinally.
3. Coelenterates.
There are about 10,000 species of Coelenterates, also known as cnidarians, several of which live in freshwater, but most in the ocean. Coelenterates have sensitive tentacles that contain groups of cnabies, called gnesite sacs. Such animals mainly include jellyfish, hydroids, sea anemones, polyps, etc.
4. Molluscs.
The phylum Molluscath is the second largest group in the animal kingdom, with more than 50,000 species. The vast majority of mollusks have one, two, or more shells of different shapes on the soft outer body, and the common ones are cephalopods, gastropods, and bivalves.
5. Echinoderms.
There are more than 6,000 species in the phylum echinoderms, including starfish, sea urchins, sea cucumbers, snake tails and sea lilies.

After watching the knife man, I feel that several should reply to the delicious sister eating.
Suqian's king crab is the new animal kingdom leader, while the traditional animal kingdom handles are: honey badger, lion and hyena. The honey badger has been named "the most fearless animal in the world" by the Guinness Book of World Records; The lion is huge, with a well-developed sense of sight, hearing and smell, and is the "Lion King" with great powers in fairy tales; The sharpest of hyenas are their teeth, with thick, tapered premolars and thick, strong jaws that bite open bones.

A zoo abroad did such an experiment - they wanted to understand the difference in the behavior of two different animals belonging to the same feline, so they put the big cat lynx and the small cat cat together. Of course, this experiment is certainly not about putting two adult little ones together! If the zoo does this, then the kittens will undoubtedly become the meat of the lynx's belly. >>>More
The three orders of the highest species of animals are:
The three orders are rodents (mammals such as rats, porcupines, beavers, capybaras), pterocodas (bats), and true-blind deficients (shrews, moles, groove-toothed shrews, etc.). >>>More
