You can see on the worm diagram above, an earthworm is a tube-shaped, segmented worm found in the phylum Annelida. Earthworms are commonly found living in soil, feeding on live and dead organic matter. An earthworm’s digestive system runs through the length of its body. It conducts respiration through its skin. The animal is elon­gated and divided into a series of ring-like segments or metameres or somites, which are separated from one another by narrow trans­verse grooves. Usually there are 120 true somites. Check out the following worm diagram below for more detailed look.

Every segment of the body, excepting the clitellar, and the first and last, bears numerous chitinous bristles called setae; these are implanted on the body wall and are arranged in the form of rings. The setae serve as hold-fasts when the worm is moving over the ground or resting in its burrow. The entire body is covered by a thin transparent cuticle which is secreted by the epidermis. The cuticle is porous and protects the body from injury. The digestive system consists of the pharynx, the esophagus, the crop, the intestine and the gizzard. Food such as soil enters the earthworm’s mouth where it is swallowed by the pharynx. Earthworms do not have lungs. They breathe through their skin. They also blood exclusively through vessels.
