Description

Apical oral view of Didinium. Showing the proboscis containing extrusive organelles to demobilize and eventually engulph it's prey. Metachronous waves of cilia in the anterior girdle of the two characteristic ciliary girdles of Didinium nasutum. To see a higher magnification view of the proboscis, see CIL:xyz. An aboral view is also grouped with this image. This micrograph was taken in 1968 by G. Antipa on a Cambridge Mark IIA operating at 20kV. The negative magnification is 945X. The raw film was scanned with an Epson Perfection V750 Pro. This image is available for qualitative 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.
