Worms are a type of animal that lives in soil, water, or air. They are segmented creatures with a head, body, and tail. Some species have no eyes, some have two pairs, and others have many more. The most common species is the earthworm. Earthworms are found in almost every part of the world. They are important because they help break down organic material and add nutrients to the soil. Earthworms also play an important role in soil formation.
