plerocercoid
the second larval stage of a pseudophyllidean cestode which follows the procercoid. This larva infects a wide range of vertebrate hosts including fish, amphibia, reptiles, mammals, birds. They are elongated, have a solid body and carry an adult scolex. As a migrating larva of a tapeworm, this is an infectious stage of importance in predation; the definitive host becomes infected by eating the tissues of the second intermediate host.
