Ventral infraciliature of the large hypotrich ciliate, Urostyla grandis (EHRENBERG,1830). A file of buccal cirri parallels the undulating membrane (UM).Em=endoral membrane.AZM=adoral zone of membranelles.There is a zig-zag file of midventral cirri (MVC) between the right and left marginal cirral rows. There is an obliquely oriented row of about 12 transverse cirri (TC).Collected from a freshwater canal near Boise, Idaho.Stained by the protargol A technique (see Foissner, W. Europ. J. Protistol., 27:313-330;1991).Brightfield.

Uroleptus (you-row-lep-tuss) an elongate hypotrich ciliate usually associated with sands and other sediments. With a curt adoral zone of membranelles at the anterior end, and a very long thin body with numerous cirri (clusters of cilia) with which the cell moves. Contractile. Phase contrast micrograph.

Uroleptus. Cell observed in sandy and muddy marine sediments in the vicinity of Broome, Western Australia in September 2003.  This work was supported by the Australian Biological Resources Study.
