Like mollusks, annelids have a true coelom and bilateral symmetry, but annelids are metameric,
which means their bodies are segmented. They gave true cephalization, but the head is not well
differentiated, their bodies are covered by an outer cuticle. There are three major groups of
annelids:
Class Polychaeta (polychete worms)
Class Oligochaeta (earthworms and bristle worms)
Class Hirudinea (leeches)
Procedure:
Observe the preserved specimens. Compare the three classes.
