http://en.wikipedia.org/wiki/Astome
Astomes (order Astomatida) are a group of ciliate protozoans commonly found in the guts of annelid worms, especiallyoligochaetes, and other invertebrates. As their name implies, these parasites are characterized by an absence of mouth. The cell is covered by uniform cilia; in addition, some astomes attach themselves to their hosts by suckers, while others use various hooks or barbs.
