------

Archiacanthocephala is a class within the phylum of Acanthocephala [2]. They are microscopic parasitic worms that attach themselves to the intestinal wall of terrestrial vertebrates, including man. They are characterised by the body wall and the lemnisci (which are a bundle of sensory nerve fibers), which have nuclei that divide without spindle formation or the appearance of chromosomes or it has a few amoebae-like giant nuclei. Typically, there are eight separate cement glands in the male which is one of the few ways to distinguish the dorsal and ventrals sides of these organisms.
