| Albertia naidis lives as endoparasite in the intestinum of Oligochaetes e.g. Nais sp.(arrow). This image shows the anterior part of such a worm that is infested by three parasites: most of the external parasites are peritrich ciliates (Rhabdostyla inclinans). (The arrowhead points to one of several specimens of the rotifer Cephalodella parasitica.) (2) |
