Tapeworms are just one of a class of parasitic flatworms, of the phylum Platyhelminthes. Thousands of species of parasitic flatworms have been identified, and live in vertebras.
Kingdom: Animalia
Phylum: Platyhelminthes
Class: Cestoda
These are the subclass in order of association:
Tapeworms are hermaphrodites, they consist of both male and female reproduction system. The reproductive system has one or many testes, cirrus, vas deferens and seminal vesicle as male organs, and a single lobed or unlobed ovary with the connecting oviduct and uterus as female organs. Although, these parasites have both reproductive systems they have to reproduce with another, which is called cross-fertilization. The life cycle of a tapeworm is not asexual, an intermediate host and a definitive host is required, which demonstrate a two-phase life cycle.
