pro·cer·coid
(prō-ser'koyd),The first stage in the aquatic life cycle of certain tapeworms, such as the pseudophyllideans (family Diphyllobothriidae), following ingestion of the newly hatched larva (coracidium) by a copepod (water flea). The procercoid develops into a tailed larva in the body cavity of the crustacean first intermediate host; when the procercoid and its host are ingested by a fish, the procercoid enters the new host's tissues and becomes a plerocercoid.
