  Trematodea \Trem`a*to"de*a\, n. pl. [NL., from Gr. ? having
     holes, from ?, ?, a hole.] (Zool.)
     An extensive order of parasitic worms. They are found in the
     internal cavities of animals belonging to all classes. Many
     species are found, also, on the gills and skin of fishes. A
     few species are parasitic on man, and some, of which the


     fluke is the most important, are injurious parasites of
     domestic animals. The trematodes usually have a flattened
     body covered with a chitinous skin, and are furnished with
     two or more suckers for adhesion. Most of the species are
     hermaphrodite. Called also {Trematoda}, and {Trematoidea}.
     See {Fluke}, {Tristoma}, and {Cercaria}.
