What exactly is a tongue slug? What effect does its mass reproduction have on the ecological balance

Slugs [kuò yú] scientific name agriolimax agrestis linnaeus, gastropod, stalk, slugs. Also known as the water snake worm, the Chinese slug.

In some areas of the south, it is called the slug (not the slug), which is a mollusk that forms a pulp with some snails.

The shell can degenerate into a lamellar structure in the body, form a row of particles, or disappear completely. Some endanger the garden. Pulmonata, commonly known as slugs, is soft, mucus-rich and lives in moist places (only one species is known to freshfishers).

Species of arionidae, limacidae and philomycidae, which are common in temperate regions, feed on fungi and leaf decay. The plant-eating sputa (veronicellidae) is found in the tropics. Carnivorous slugs that eat other snails and earthworms include the European family Testacellidae.

The marine gastropods of the subclass Opisthobranchia are sometimes referred to as sea slugs.

Herbivore grape leaves into holes, or by-herbivore grape fruits, affect the value of the commodity. It is a pest animal with complex feeding habits and large appetites.
