Parasitic Trematoda of fish

Bucephalidae is a family of trematodes that parasitize fish. They lack suckers, having instead a muscular organ called a "rhynchus" at the front end which they use to attach to their hosts. The characteristics of the rhynchus are used to help define the genera of the family. It is one of the largest digenean families, with 25 genera containing hundreds of described species. Bucephalids are cosmopolitan, having been recorded all over the world. They are parasites of fish from freshwater, marine, and brackish water habitat types.

Rugogastridae is a family of trematodes in the order Aspidogastrida. It consists of a single genus, Rugogaster Schell, 1973.

Tylodelphys is a genus of parasitic fluke that infects the small water fish. It induces many behavioral changes on its host. Once inside a fish's eye, it can cause partial blindness and several behavioral changes to the intermediate host. Other species of flukes are able to turn into dormant cysts at certain stages of development, but Tylodelphys spp. stays active and roams free inside the fish's eye, giving it an opportunity for it to induce parasite behavior. When Tylodelphys larvae crawl around the inside of the fish's eye, it can get in between the retina and the lens. This can cause parti
