V. The two types of larvae found in the life cycle of Diphyllobothrium spp are 1. Procercoid larva (tailed larva that develop in the body cavity of copepod) 2. Plerocercoid larvae (sparganum): occurs in the muscles of the fishes VI The three types of larvae found in the life cycle of trematodes are: 1. Miracidium ( released from the egg) 2. Sporocyst ( forms inside the snail first intermediate host) 3. Redia ( also forms inside snail first intermediate host) Solution V.
