CIL:39250
NCBI Organism Classification
Didinium nasutum
Biological Process
phagocytosis
Cellular Component
oral apparatus
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...

NCBI Organism Classification
Paramecium tetraurelia
Biological Process
microtubule cytoskeleton organization
Cellular Component
cell cortex
High resolution view of the quadrulus membranelle (4 rows of cilia) in the buccal cavity of Paramecium tetraurelia labelled for tubulin. Microtubules of the axonemes of the cilia and the triplet fiber...
CIL:21995
NCBI Organism Classification
Didinium nasutum
Biological Process
phagocytosis
Cellular Component
oral apparatus
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 ...

NCBI Organism Classification
Didinium nasutum
Biological Process
phagocytosis
Cellular Component
oral apparatus
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...

NCBI Organism Classification
Didinium nasutum
Biological Process
phagocytosis
Cellular Component
oral apparatus
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...

NCBI Organism Classification
Didinium nasutum
Biological Process
response to toxin
Cellular Component
cell cortex
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...

NCBI Organism Classification
Didinium nasutum
Biological Process
phagocytosis
Cellular Component
oral apparatus
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...

NCBI Organism Classification
Euplotes sp.
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
A view of the cytopharynx and its nascent food vacuole forming region. The flattened pharyngeal vesicles that may contain monolayers or bilayers of lipids seem to be equivalent to the discoidal vesicl...
CIL:19537
NCBI Organism Classification
Didinium nasutum
Biological Process
oral apparatus organization
Cellular Component
oral apparatus
The proboscis of Didinium. While not well preserved, this image clearly shows the clockwise surface ridges that are elevated by ribbons of microtubules that are involved in supporting the buccal cavit...
