Holophrya Ehrenberg 1831

The ciliate Holophrya, with a polar mouth which is surrounded by stiff rods (nemadesmata) that can be used to manipulate food into the body. Normally eats algae and detritus. Differential interference contrast.

Holophrya ovum (Ehrenberg,1831). The yellow arrowhead indicates the three dorsal brush rows of short cilia. DIC

Holophrya ovum (Ehrenberg,1831). The yellow arrowhead indicates the three dorsal brush rows of short cilia. Stained by the silver carbonate technique (see Foissner, W. Europ. J. Protistol., 27:313-330;1991).Brightfield.

Anterior view of Holophrya ovum (Ehrenberg,1831). The yellow arrowhead indicates the pattern of the silverline system. The red arrowhead indicates the dorsal brush rows.The silverline system in the circular area around the cytostome is more densely stained than in the rest of the cell.Stained by the silver carbonate technique (see Foissner, W. Europ. J. Protistol., 27:313-330;1991).Brightfield.

Dorsal brush of the enklitoloph-dexiotrop configuration in Holophrya ovum (Ehrenberg, 1831).Stained by the silver carbonate technique (see Foissner, W. Europ. J. Protistol., 27:313-330;1991).Brightfield.

The yellow arrowead indicates the faintle visible anterior ends of the trichites supporting the cytopharynx. the red arrowhead indicates the dikinetids of the undulating membrane. Only the dikinetids on the left of the cytostome are stained here. Stained by the silver carbonate technique (see Foissner, W. Europ. J. Protistol., 27:313-330;1991). Brightfield.

Predatory / detritus consuming ciliate, with anterior ingestion area subtended by stiff nemadesmata. Cell with symbiotic algae. Macronucleus upper right, contractile vacuole at the posterior end of the cell. Nomarski optics of living cell.
