Biology     Glossary (e.g. epibenthic)

Found in free swimming parasitic copepods captured in plankton nets. Transfers from one copepod host to another when these crustacean parasites are mating (a sexual disease of copepods). May feed on parasitic copepods instead of fish host; covers these crustacean parasites with eggs that are probably detrimental. May harm other parasites and may actually benefit fish host (Ref. 359). Members of the class Trematoda are parasitic, thus requires a host to survive. Life cycle: Eggs are passed on to the feces of the hosts. Embryos hatch into miracidia and penetrate the tissues of snails where they further undergo three stages: sporocysts (Ref. 833).
