Description

Didinium ingests Paramecium. Also showing a few discharged trichocysts and metachronous waves of cilia in the two characteristic ciliary girdles of Didinium nasutum. This micrograph was taken in 1968 by G. Antipa on a Cambridge Mark IIA operating at 20kV. The negative magnification is 410X. 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.
