Didinium captures Paramecium. A moment after initial contact when toxicysts enter Paramecium. The strand of toxicysts can be seen between the two organisms, and Didinium will use the anchored toxicyst...

Didinium captures Paramecium. It is not unusual for an undersized Didinium to attempt to ingest a much larger Paramecium. In this case, the organisms were preserved before the outcome could be determi...

Conchophthirus was deciliated by calcium ion shock followed by shearing through a micropipette. This revealed the location of the deciliated basal bodies and the cell's surface architecture. In this i...

Figure 326 from Chapter 13 (Cilia and Flagella) of 'The Cell' by Don W. Fawcett M.D. Cells of sense organs detecting vibration are provided with stiff surface projections, the size of cilia but lackin...

Didinium attacks Paramecium. Also showing many discharged trichocysts and metachronous waves of cilia in the two characteristic ciliary girdles of Didinium nasutum and on Paramecium. A series of captu...

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 nas...
