Right anterolateral view
Right anterolateral view of the marine heterotrich ciliate Condylostentor auriculatus (KAHL,1932) JANKOWSKI,1978. The length/width ratio is approximately 2:1.Condylostentor auriculatus differs from species of Condylostoma in that the flared anterior end and its adoral zone of membranelles is separated into two lateral lobes by a deep ventral cleft (seen well in this image). Vestibular kineties parallel the anterior margin but do not extend into the more proximal vestibulum. The moniliform macronucleus of C. auriculatus parallels the lateral wall of the cell then curves around the anterior margin of the cell opposite the ventral cleft. No contractile vacuole. Mostly attached to filamentous algae but sometimes free-swimming. Collected from seawater aquarium in Boise, Idaho January 2004. Brightfield.
