Didinium ingests Paramecium. Also showing a few discharged trichocysts and metachronous waves of cilia in the two characteristic ciliary girdles of Didinium nasutum. This micrograph was taken in 1968 ...

The ingestion of Paramecium by Didinium. This micrograph also clearly shows the five short rows of clavate cilia (ciliary stubs without central microtubules) that reside just below the anterior and po...

Didinium captures Paramecium. Also showing metachronous waves of cilia in the two characteristic ciliary girdles of Didinium nasutum. This micrograph was taken in 1968 by G. Antipa on a Cambridge Mar...

Didinium intiates capture of Paramecium. Believe-it-or-not, this Didinium may accomplish the ingestion of the Paramecium in less than one minute. See other images in the link below. Also showing metac...

Didinium ingests Paramecium. Note that Paramecium is nearly the waiting food vacuole and the proboscis of Didinium is beginning to reform. This micrograph also shows the metachronous waves of cilia in...

Didinium ingests Paramecium. Note that Paramecium is folded in half as it is compressed and enters the waiting food vacuole. This micrograph also shows a few discharged Paramecium trichocysts as well ...

Only the macronucleus contains nucleoli which is the site of ribosomal RNA synthesis and ribosome subunit assembly. This EM also contains the distal end of the food vacuole forming cytopharynx which c...

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. 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...
