Infraciliature of the common marine scuticolciliate, Uronema marinum (DUJARDIN,1841). The red,yellow and green arrowheads indicate the 1st,2nd and 3rd adoral membranelle respectively. the blue arrowhead indicates the right paraoral membrane. Collected from effluent of the protein skimmer of a commercial marine aquarium in Boise, Idaho. January 2007.Stained by a silver carbonate technique for marine ciliates.

Urocyclon (your-owe-sigh-clone) a small scuticociliate, mouth small and located about mid-way down the body. These cells are in focus on the surface, and elements of the infraciliature - the skeletal network associated with the bases of the cilia) are evident. Phase contrast micrograph.

Right ventrolateral view of infraciliature of the scuticociliate, Homalogastra setosa (KAHL,1926).The oral aperture is in the posterior 1/3 of the cell. The blue arrowhead indicates the paraoral membrane to the right of the cytostome. The 2nd and 3rd adoral membranelles are indicated by the yellow and green arrowheads respectively. The small 1st adoral membranelle is not seen here. The two macronuclei indicate that this is an exconjugant specimen.Trophonts have a single spherical macronucleus and a spherical micronucleus. From non-flooded petri dish culture of topsoil from a public park in Boise,Idaho. Stained by the silver carbonate technique (see Foissner, W.Europ. J. Protistol.27:313-330;1991).Brightfield.

Portrait of the common marine scuticociliate, Uronema marinum (DUJARDIN,1841). The large spherical macronucleus (MN) is just anterior to the cell center. The oral apperatus is indicated by the yellow arrowhead. The small subterminal contractile vacuole is indicated by the green arrowhead. A food vacuole is indicated by the red arrowhead. The long terminal cilium is indicated by the light blue arrowhead. Collected from effluent of the protein skimmer of a commercial marine aquarium in Boise, Idaho. January 2007. DIC.
