What's the difference between loach and earthworm?

The loach is a vertebrate. Earthworms are invertebrates. In appearance, one is big and the other is small. Misgurnus lives in water and earthworms live on land.

Misgurnus anguillicaudatus belongs to Misgurnus. Misgurnus anguillicaudatus, known as "ginseng in water", is distributed all over southern China, but it is not common in the north, but it can also be seen everywhere. It can be harvested all year round, most in summer. After the loach is caught, it can be eaten raw or dried. Misgurnus anguillicaudatus lives in lakes and swamps and is the smallest, only three or four inches long. It is round and short, with small scales under its skin, blue and black in color, and covered with its own mucus, which is too greasy to hold. It is a kind of fish with high nutritional value.

Earthworms are a general term for oligochaeta in annelids. Scientifically, they belong to one-way earthworm order. Both sides of the body are symmetrical and divided; Without bones, the body surface is covered with a thin layer of pigmented stratum corneum. Except for the first two sections of the body, all other sections have bristles. 1837 is called the most valuable animal on earth by biologist Darwin. Earthworms are called lumbricus (open-edged lumbricus, wide lumbricus) in Chinese medicine, and it is said in Compendium of Materia Medica that they have the effects of dredging meridians, promoting blood circulation and removing blood stasis.
