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...

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...

Clathrin-mediated endocytosis This animation shows the process of clathrin-mediated endocytosis of transferrin receptors, focusing on the assembly and disassembly of the clathrin cage. A single tris...

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 ...

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 magnif...

This animation shows the process of clathrin-mediated endocytosis of transferrin receptors, focusing on the assembly and disassembly of the clathrin cage. A single triskelion, which is approximately 1...

Transmission electron micrograph of coated vesicles in mouse cardiac tissue. Coated vesicles have the materials bound to the receptor molecules incorporated within their membranes allowing the vesicl...

High resolution image showing that one parasomal sac lies anterior to each basal body of the somatic ciliature. A parasomal sac is an indentation of the plasma membrane that penetrates into the cytoso...
