Annelid, phylum name Annelida, also called segmented worm, any member of a phylum of invertebrate animals that are characterized by the possession of a body cavity (or coelom), movable bristles (or setae), and a body divided into segments by transverse rings, or annulations, from which they take their name.
The head and the rear of the body is not segmented. The digestive system of species in this phylum runs the length of the body. Food is taken in at one end of the body and expelled at the other end. Annelids have two sets of muscles that help them move.here are about 15,000 species in this phylum. The phylum includes earthworms, leeches, and marine worms known as polychaetes. Species in this phylum have metameric bodies. Metameric bodies are divided into segments called annuli. The annuli are covered in tiny hairs called setae. Setae help the worms move.
