Description

Didinium ingests Paramecium. At the midpoint of engulfment, some 30 seconds after contact. This micrograph was taken in 1968 by G. Antipa on a Cambridge Mark IIA operating at 20kV. The negative magnification is 544X. This image needs to be flipped either vertically or horizontally to be properly viewed. Further details are available at Wessenberg, H. and Antipa, G. 1970.
