Description

The ingestion of Paramecium by Didinium. This micrograph also clearly shows the five short rows of clavate cilia (ciliary stubs without central microtubules) that reside just below the anterior and posterior ciliary girdles. A higher magnification of these cilia on a different cell is available at (CIL:19538). Also the metachronous waves of coordinated cilia in both the anterior and posterior girdles of Didinium are evident. This micrograph was taken in 1968 by G. Antipa on a Cambridge Mark IIA operating at 20kV. The negative magnification is 422X. The raw film was scanned with an Epson Perfection V750 Pro. This image is available for quantitative analysis. Further details are available at Wessenberg, H. and Antipa, G. 1970. Capture and ingestion of Paramecium by Didinium nasutum. J. Protozool. 17:250-270.
