Portrait of the large colpodid ciliate, Colpoda magna (Gruber, 1879) Lynn, 1978.The cell is broadly reniform and moderately laterally compressed. A narrow furrow spirals posteriorly for one complete turn around the body from entrance of the vestibulum. This results in a lobed appearance, the lobe anterior to the furrow being larger. The lobe posterior to the furrow is bipartite due to the presence of a small terminal lobulation (seen here). Somatic ciliation is uniform with kineties composed of doubly ciliated dikinetids spiraling about the long axis. Kineties in the spiral furrow are more closely spaced. The oral apparatus is in the anterior or central 1/3 of the cell. There are two curved membranelles (polykinetids), one on the right and the other on the left side of the vestibulum. Single posterior contractile vacuole occupies most of the small terminal postoral sack. It is surrounded by cytoplasmic crystals that appear black in this brightfield view. The contractile vacuole has six to nine long collecting canals, which radiate anteriorly. The central macronucleus is ovoid. There are multiple micronuclei (2 to 16). Division occurs within cysts. Collected from a temporary rainwater pool with decaying grass near Boise, Idaho March 2005. Brightfield, closed condenser.

Left side of the large colpodid ciliate, Colpoda magna (Gruber, 1879) Lynn, 1978.The cell is broadly reniform and moderately laterally compressed. A narrow furrow (seen here as a notch to viewer's left) spirals posteriorly for one complete turn around the body from entrance of the vestibulum. This results in a lobed appearance, the lobe anterior to the furrow being larger. The lobe posterior to the furrow is bipartite due to the presence of a small terminal lobulation.

Infraciliature (ventrolateral view) of the large colpodid ciliate, Colpoda magna (Gruber, 1879) Lynn, 1978.The cell is broadly reniform and moderately laterally compressed. Somatic ciliation is uniform with kineties composed of doubly ciliated dikinetids spiraling about the long axis. Kineties in the spiral furrow are more closely spaced. The oral apparatus is in the anterior or central 1/3 of the cell (anteriorly to viewer's right).

Detail view of the oral polykinetids of the large colpodid ciliate, Colpoda magna (Gruber, 1879) Lynn, 1978.The cell is broadly reniform and moderately laterally compressed. A narrow furrow spirals posteriorly for one complete turn around the body from entrance of the vestibulum. Somatic ciliation is uniform with kineties composed of doubly ciliated dikinetids spiraling about the long axis. Kineties in the spiral furrow are more closely spaced. The oral apparatus is in the anterior or central 1/3 of the cell. There are two curved membranelles (polykinetids), one on the right and the other on the left side of the vestibulum. The crescentic right oral polykinetid is well seen here. Only the folded posterior end of the left oral polykinetid is seen here (triangular structure to viewer's left of posterior end of the right polykinetid). The central macronucleus is ovoid (distorted into bilobed shape by formalin fixation in this image). There are multiple micronuclei (2 to 16). Two micronuclei are seen here superimposed on the macronucleus. Collected from a temporary rainwater pool with decaying grass near Boise, Idaho March 2005. Stained by the silver carbonate technic (see Foissner, W. Europ. J. Protistol., 27:313-330;1991). Brightfield.

Silverline system of the large colpodid ciliate, Colpoda magna (Gruber, 1879) Lynn, 1978. The longitudinal primary meridians are punctuated by black dots representing dikinetids. The primary meridians are connected by tranverse elements giving the silverline system a characteristic reticular pattern. Stained by the dry silver nitrate technic (see Foissner, W. Europ. J. Protistol., 27:313-330;1991). Brightfield.Black and white.

Colpoda steinii (MAUPAS,1883). There are two longer caudal cilia (green arrows) arising from a dikinetid near the excretory pore of the contractile vacuole. These are seldom visible in vivo due to very rapid beating. For this reason some illustrations of this species fail to include the two long caudal cilia.They are clearly seen on scanning electron microscopy.DIC.

Colpoda steinii (MAUPAS,1883). The green arrow indicates the right oral polykinetid and the blue arrow shows the left oral polykinetid. The left polykinetid has a unique Paddle or spoon shape as seen here. The relatively small right and left oral polykinetids are almost perpendicular to one another in this species but in this image their relationship has been slightly distorted.Stained by the silver carbonate technique (see Foissner, W. Europ. J. Protistol., 27:313-330;1991). Brightfield.
