Introduction

Trematodes are parasitic, unsegmented, flattened (rarely cylindrical) worms. They have ventral, anterior, posterior or median attachment organs. The sense organs are poorly developed. The mouth is terminal or ventral and subterminal. The intestine is usually forked with or without lateral branches. The animals, with few exceptions, are hermaphroditic. The ovary is usually single. They have one, two, or more testes. The development is direct with only one host in the ectoparasitic Monogenea and indirect in the Digenea which have two or more hosts. The digenetic trematodes usually parasitize vertebrates which serve as their primary hosts and invertebrates (Mollusca) which …
