Annelids (Annelida) are truely segmented worms with a body cavity (coelom). They are found in most wet environments, and include leeches (Hirudinea), earthworms (Oligochaeta) and bristle worms (Polychaeta), We provide comprehensive descriptions including morphology, life cycle, and other biological features of these worms with a closed circulatory system.

These are the most highly developed helminths, having segmented bodies, a circulatory system, nephridia (part of a primitive excretory system, but still much more advanced than the flame cells of, for example, the Platyhelminthes), a highly developed digestive system, and a primitive brain.
