Scuticociliatia

Calyptotricha (kah-lip-toe-trike-a) pleuronemoides is an ovoid to pyriform ciliate. The ciliate forms a transparent lorica. The lorica is tube-like and has apertures at both ends. The middle the tube can have parallel sides or a central bulbous region in which the ciliate is housed. The undulating membrane of the oral aperture stretches down the right side of the body to form a pouch in the posterior body half. Extrusomes are present. There is a conspicuous caudal cilium. Contractile vacuole in posterior body region. The macronucleus is spherical with attached micronuclei. Several endosymbiotic algae are visible and the conspicuous caudal cilium. Ciliate measuring 28 microns, lorica 64 microns. This specimen was collected in freshwater ponds near Konstanz, Germany. Differencial interference contrast.

Portrait (dorsal surface) of the cinetochilid scuticociliate ciliate, Sathrophilus muscorum (Kahl, 1931) Corliss, 1960. The ellipsoid cell is dorsoventrally flattened. The left side is slightly convex and the right side more straightened. The approximately triangular cytostome is at the junction of the first and middle 1/3. There are three obliquely oriented adoral membranelles. M1 is longest, M2 intermediate in length and M3 quite short. There is a short, slightly curved paraoral membrane bordering the right margin of the peristome. The oral apparatus is quite similar to that of Cinetochilum margaritaceum. The central spherical macronucleus is usually single but may be in as many as four parts. There are 12-17 longitudinal somatic kineties that run between prominent pellicular ridges. There is a single long caudal cilium that inserts on the dorsal surface (seen here). There is a short preoral and longer postoral suture. The slit-like cytoproct is in the postoral suture. There are inconspicuous wedge shaped peripheral extrusomes. Its ellipsoid shape and pellicular characteristics differentiate S. muscorum from the similar Cinetochilum and Platynematum both of which have more truncate notched posterior margins. Collected from sapropelic bottom sediments of a freshwater aquaculture tub near Boise, Idaho. DIC.
