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.
