The larva penetrates the wall of the fish’s intestine to the body cavity, where it is converted to a plerocercoid. If the definitive host (a man, dog, or cat for the broad fish tapeworm; aquatic birds for Liguld) eats the affected fish, the plerocercoid is transformed into an adult worm in the new host’s intestine. plerocercoid ple·ro·cer·coid (plē'rō-ser'koyd), A stage in the development of a tapeworm following the procercoid stage, which develops in an animal serving as the second or subsequent intermediate host; a wormlike nonsegmented larva with an invaginated scolex at one end, usually unencysted in the flesh of various fishes, reptiles, or amphibians, the ingestion of which transmits the parasite to the final host.
