What is a mother sporocyst?
Sporocysts are elongated sacs that produce either more sporocysts or rediae. This is where larvae can develop. Mother Sporocyst: These have loose plates (cilia) and migrate to gonads. Daughter Sporocyst: These are an asexual production of cercariae; they absorb nutrients while having no mouth.
Who have Operculated eggs?
D. latum is the only cestode (tapeworm) which lays eggs that are operculated.
What is Plerocercoid larva?
