This is the male of Schistosoma mansoni with the stouter body, gynecophric canal (more apparent to the
right), and the two anterior suckers. The oral sucker is around the mouth and the acetabulum
is a short distance posterior to the oral. Note that slightly above and
to the right of the acetabulum are the linear row of 7 testes. 100x
anterior view of the male S. mansoni with the oral sucker to extreme left, acetabulum in
the foreground and the linear row of testes to the right. The adults live
in the posterior mesenteric veins in humans, delivering egg capsules which
burrow through the vein wall into the large intestine with damage to vein and
intestinal wall occurring. 400x
