Earthworms are nocturnal annelids and like temperature, humidity, quietness, light, salt and tannin. Inhabit in moist and well-ventilated soil during the day. Habitat depth is generally 10 ~ 20 cm, and they come out for food at night. It feeds on rotten leaves, hay, vegetable scraps, crop straws, livestock manure, melon and fruit peels, waste residue from paper mills, breweries or flour mills, and domestic garbage in residential areas. I especially like sweets, such as rotten fruits, and sour materials, but I don't like bitter materials and tannins. Salt is toxic to it. Earthworms are animals with poor aerobic capacity. Very sensitive to the surrounding environment, suitable for living in loose soil with 15 ~ 25 degrees, humidity 60% ~ 70% and PH 6.5 ~ 7.5. If the conditions are not right, it will climb out and escape.

Earthworms are the "Hercules" who cultivate the soil. Through their activities, the soil becomes loose and the aggregate structure is strengthened, thus promoting the growth of crops. Earthworms have a wide range of food habits, and many organic substances that pollute the environment can be used as their food. Therefore, using it to treat organic wastes and purify the environment, earthworms also have the characteristics of high reproduction rate and rich protein content, so breeding earthworms is also an effective way to solve animal protein feed. In addition, the medicinal value of earthworm is very high, and it has the functions of relieving fever, spasmolysis, asthma, lowering blood pressure, diuresis and dredging collaterals.

Earthworms are divided into terrestrial and aquatic species. Among them, the aquatic species is the silk earthworm commonly known as the red worm.

Earthworms are annelids with ring-shaped segments. Generally speaking, earthworms have more than 80 knots. From the appearance, the mature earthworm has segments near the head besides slicing, and the segments will be combined into bands. Take earthworms as an example. There is a female hole in the ring belt, which is where earthworms excrete eggs. There are two male holes behind the girdle, which are the places where earthworms excrete sperm; There is often a mastoid around the male hole, which is called mastoid. Male foramen and mastoid are important basis for distinguishing earthworm species. However, most earthworms can't be identified by appearance, so they need to be dissected, and their species can be identified by the number, size, shape and location of their internal structures such as seminal vesicle, prostate and intestinal caecum.

Earthworms are hermaphroditic and hybrid. It feeds on organic matter in soil and tender stems and leaves of plants, and the soil discharged after eating a lot of soil is called dung, which often accumulates in holes or caves on the surface; When there are a large number of earthworms and frequent activities, the soil becomes loose due to digging, which is beneficial to plant growth. Earthworms are also an important food source for some mammals (such as weasels and badgers), birds (such as chickens and ducks), frogs, snakes (such as green snakes) or fish, shrimp and crabs. Where do earthworms live? In wet soil. It can't be in too wet soil. It doesn't like too much water. : "in the vegetable garden", "in the field", "in the garbage" ...)

The interesting thing about earthworms is that they can be used for fishing. It can also be used to feed chickens, ducks and geese. Earthworms are also a small animal with rich nutrition. Now many people specialize in raising earthworms as feed for fish and ducks, and there are also companies specializing in earthworm food abroad! Earthworms break and live, and grow into two earthworms.

Earthworms have no feet. Earthworms crawl on their bodies. When climbing, first put out the front, then take back the back, then put out the front and take back the back, so as to climb forward. When an earthworm crawls, its body is thick, short, thin and long. Earthworms have two heads, and both can climb forward.

Earthworms are afraid of light. Earthworms have sticky mucus. Earthworms have soft bodies. Earthworms have no eyes. In nature, Qiuyin not only drinks water, but also eats in wet soil.
