Description
Didinium captures Paramecium. The cytostome opens at the end of the proboscis to accept its prey. Also showing metachronous waves of cilia within the two characteristic ciliary girdles of Didinium nasutum; the waves on Paramecium may be paralyzed due to the effects of the attached toxicysts. This micrograph was taken in 1968 by G. Antipa on a Cambridge Mark IIA operating at 20kV. The negative magnification is 485X. Further details are available at Wessenberg, H. and Antipa, G. 1970.
