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...

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...

Scanning electron micrograph reveals microvilli on the surface of HeLa cells in culture. Image by Keith Porter. Figure 31 from Chapter 2 (Specializations of the Free Surface) of 'The Cell, 2nd Ed.' b...

Scanning electron micrograph of the calcium skeleton of coral polyp. The sample was cleaned with bleach solution, dried and carbon coated prior to imaging. The image was collected using a secondary...

Figure 317 from Chapter 13 (Cilia and Flagella) of 'The Cell' by Don W. Fawcett M.D. The inconsistent orientation of the cilia in scanning micrographs does not accurately reflect their state in the li...

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 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...

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...
