[Schistosoma haematobium] [Schistosoma intercalatum] [Schistosoma japonicum] [Schistosoma mansoni] [Schistosoma mekongi]

Adults of Schistosoma mansoni.  Unlike the flukes, adult schistosomes have the sexes separate, with the female residing in a gynecophoral canal within the male.  Male worms are robust, tuberculate and measure 6-12 mm in length. Females are longer (7-17 mm in length) and slender.  Adult S. mansoni reside in the venous plexuses of the colon and lower ileum and in the portal system of the liver of their host.
