What kind of animal is an earthworm and what kind of animal does an earthworm belong to

Earthworms are invertebrates.

Earthworms, also known as earth dragons, are terrestrial invertebrates of the phylum Annelids.

Earthworm (earthworm) is one of the annelids, there are more than 3 species of earthworms in the world, and there are more than 2 species in China.

There are ringworms, Aisheng worms, heterolip worms, dura worms and other varieties widely distributed throughout the country. Earthworms are rich in nutrition, rapid reproduction, miscellaneous diets, and high yield in artificial breeding.

Good economic benefits. Earthworms can be used as a valuable medicine** for many diseases, and can also be used as high-protein food and feed. Earthworms dig holes to loosen the soil, decompose organic matter, create good conditions for the growth and reproduction of soil microorganisms, and play a special role in soil improvement, eliminating public pollution, protecting the ecological environment, in material cycle, biodiversity, etc.

Earthworms are terrestrial invertebrates of the phylum Oligochaetidae.

Living in the soil at night and feeding on livestock and poultry manure and organic waste, earthworms can loosen soil, improve soil, improve fertility and promote agricultural production, and are known as "ecosystem engineers".

Earthworms do not have respiratory organs, but because of the distribution of a large number of microvascular networks on the body surface, in the case of humidity, it is easy to exchange gases, mainly in the surface of the soil, where organic matter is relatively rich, soil structure, pH, water content, aeration, etc. are all factors that limit its distribution and quantity.

Earthworms are commonly known as earth dragons. It lives in moist, loose and fertile soil, and has a long cylindrical body with a slightly lighter brown color, consisting of about 100 body segments. The anterior segment is slightly pointed, the posterior end is slightly rounded, and there is a segmented inconspicuous ring at the anterior end.

The ventral surface is light-colored, with bristles in the middle of most body segments, which play a fixed supporting role and assist movement when earthworms crawl. Earthworms have a keen sense of taste and prefer sweets and sourness. Bitter taste.

Earthworms are cold-blooded invertebrates, and external temperature changes will have a huge impact on earthworm activity and survival, and earthworm activity is generally better at a temperature of 20-27. Earthworms are hermaphroditic, which means that the way it reproduces can be solved on its own. Earthworms do not have lung organs, and the respiration process needs to capture oxygen through **, so the soil moisture content will have a great impact on earthworms.

Earth dragons are earthworms.

Geosaurus is the dried body of the Pheretimaaspergillum (Eperrier), Pvulgarischen, Pguillelmi (Michaelsen) or Pectiniferamichaelsen of the phylum Annelids. The former is known as "Guangdi Dragon", and the latter three are known as "Ludi Dragon", which are mainly produced in Guangxi, Guangdong and Fujian. Its nature is cold, salty, clear heat and calm shock, painful menstrual activation, asthma and diuretic; It is used for cerebral thrombosis, cerebral infarction, coronary heart disease, stroke, joint paralysis, limb numbness, hemiplegia, hypertension and other diseases.

Dilong protein is extracted from Dilong, which contains collagenase, plasmin, vermikinase, nucleic acids, trace elements and other components, and is widely used in drugs. Dilong extract, Dilong has been successfully developed through high-tech extraction, such as Weiluo Kang Dilong protein, Dilong protein soft capsules, etc. It has been widely used in clinical practice, and is increasingly used in the prevention and center of cardiovascular, cerebrovascular, endocrine, respiratory and other diseases.

Earthworms are a common species of terrestrial annelids, and they are also invertebrates.

They live day and night in the soil, feed on livestock and poultry manure and organic waste, and swallow together with the soil, as well as decaying stems and leaves of plants. Earthworms can loosen soils, improve soils, improve fertility and increase agricultural yields. There are about 3,000 species of earthworms in the world, and 229 species have been recorded in China.

Invertebrates refer to animals that do not have a vertebral column on their 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.

Earthworm benefits for the ecological environment:

Earthworms are both consumers, decomposers, and regulators in ecosystems, and play an important role in changing soil fertility and soil texture. Earthworms are more effective at cultivating the soil than ploughing, enhancing soil aeration. It provides beneficial bacteria that convert ammonia in the soil into a form that is easy for crops to absorb and utilize, and helps to break down various complex molecules in the soil into components that can be used by plant roots.

Earthworms can timely crack the remaining deciduous dead grass on the ground into nutrient substances for soil and plants, which can treat animal manure and urban waste, which is of great significance to organic agriculture and ecological agriculture.
