Annelids are segmented worms characterized by their ringed bodies with repeating segments that contain internal organs. They have a coelom, a fluid-filled body cavity lined with mesoderm, and typically possess bristles called setae on each segment. Annelids also have a well-developed nervous system with a ventral nerve cord and a closed circulatory system with blood vessels.
