Five rows of clavate cilia that reside just below the anterior ciliary girdle of Didinium nasutum. This micrograph also shows a partial view of the pectinelle rows of the anterior girdle of cilia. The...

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...

The aboral view of Didinium showing seven contractile vacuole pores for it's single posterior contractile vacuole and metachronous waves of cilia in one of the two characteristic ciliary girdles of Di...

Conchophthirus was deciliated by calcium ion shock followed by shearing through a 22 gauge needle. This revealed the location of the deciliated basal bodies and the cell's surface architecture. In thi...

Didinium nasutum showing the two prominent girdles of cilia in full metachronous beat. If you look at higher magnification you will see the occasional short, blunt clavate cilia. These are known to no...
