Trematodes (Flukes)omes) with which they can attach in the host. They are sometimes hermaphrodite, sometimes with separate sexes. The trematodes of man always undergo their larval development in one or in two intermediate hosts, whereas in the final (definitive) host the parasite becomes the sexually mature helminth (

Trematodes (Flukes)se may develop into metacercariae in a second intermediate host (fish, snail, ant or plants) or — in the case of schistosomes — bore percutaneously into the definitive host, to then become sexually mature parasites. The metacercariae reach the alimentary tract of the definitive host via the oral route.
