worms have bodies that consist of a series of similar, repeating
compartments or segments. These worms are bilaterally symmetrical,
and they have organ systems, including a nervous system and a closed
circulatory system. Almost all marine annelids are in the Class
Polychaeta. Each body segment has a pair of flattened extensions
or parapodia that sometimes have sharp bristles (or setae). Polychaete
worms have diverse lifestyles that include deposit feeding, carnivory,
