The cell body measures 100-300 micron in lenght and is dorsoventrally flattened, with a rounded anterior end and a slyghtly pointed posterior end. It has two ovoid macronuclei and two spherical micronuclei. The somatic ciliature consists of 8 frontal cirri, 5 trasverse cirri, 3 caudal cirri, 20-25 right marginal cirri and 15 left marginal cirri ( Tuffrau, 1965 ).

Chaetospira muelleri (LACHMAN,1856). The corkscrew shaped highly contractile anterior end of the cell is seen protriding through the opening of the flask-shaped lorica. Collected from tidal pools at Alki Beach, Seattle, Washington 47°35â41.25âN 122°23â19.60âW.January,2006. DIC.

Portrait of Halteria oblonga (Kellicott, 1885; Kahl,1932), a spirotrich ciliate. The body is slightly elongate, rounded posteriorly and truncate anteriorly. There is a prominent anterior wreath of adoral membranelles that winds clockwise into the funnel-shaped peristome (seen in this image). The somatic ciliature is reduced to widely spaced longitudinal files of stout double cilia. The posterior cilia are longer with a characteristic J-shape. These trail behind the organism during swimming, which is accomplished by the rapid beating of the AZM. The single peripheral contractile vacuole is located in the anterior 1/3 adjacent to the oral aperture. The single spheroid granular macronucleus and single round micronucleus are seen posterior to the contractile vacuole. Although Kahl (I. Wimpertiere oder Ciliata. 3. Spirotricha pp. 505-506, Gustav Fischer Verlag, 1932) describes endosymbiotic zoochlorellae, at least some of the algae in these individuals appear to have been ingested. Collected from organically enriched freshwater pond near Boise, Idaho June 2003. DIC optics.

Ventral infraciliature of the marine urostylid ciliate, Pseudokeronopsis carnea (Cohn, 1866) Wirnsberger, Larsen & Uhlig, 1987. Collected from a salt water aquarium on the campus of Boise State University, Boise, Idaho. April 2009. Protargol. Brightfield.

Ventral infraciliature of the oxytrichid,Gonostomum strenuum (ENGELMANN, 1862) STERKI, 1878. G. strenuum differs from G. affine by the greater number of frontoterminal (4-6 vs 2) and frontoventral cirri. In G. strenuum the last frontoventral cirrus is just posterior to the peristome (yellow arrowhead).Collected from a non-flooded Petri dish culture of soil from a park lawn in Boise, Idaho. January 2007.Stained by the protargol technique [Wilbert modification] (see Foissner, W. Europ. J. Protistol., 27:313-330;1991).Brightfield.

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.

Chaetospira muelleri (LACHMAN,1856). This individual is completely retracted into the the flask-shaped lorica. Collected from tidal pools at Alki Beach, Seattle, Washington 47°35â41.25âN 122°23â19.60âW.January,2006. DIC.

Portrait of the stichotrichine ciliate, Chaetospira remex (Hudson,1875; Kahl,1932). This species occupies a long, sometimes branched tubular lorica into which it intermittently retracts (as seen in this image). The lorica is attached to the substratum. C. muelleri has a flask-shaped lorica. The cell body is slender,elongate and very contractile. The corkscrew shaped anterior bears a prominent adoral zone of membranelles along the peristome. The somatic ciliature is reduced to right and left marginal and two ventral files of short cirri which spiral down the body. The macronucleus is bipartite. the contractile vacuole is in mid-body between the two macronuclei. Feeds mainly on bacteria, flagellates and diatoms. Collected from a freshwater pond near Boise, Idah May 2004. DIC optics.
