Leptospironympha, a parasite of the wood-feeding cockroach Cryptocercus punctulatus.

Figures 10–15. SEM micrographs of Leptospironympha of Cryptocercus punctulatus showing symbiotic bacteria and surface details. 10. Symbiotic surface bacteria between flagellar bands of L. eupora (Scale bar=5 μm). 11, 12. Symbiotic surface bacteria on the posteriormost cell portion of L. wachula (Scale bars=3 μm and 2 μm respectively). 13. Granular particles on the flagella of L. eupora (Scale bar=1 μm). 14. Operculum of L. eupora, also showing flagella with a few granular particles (Scale bar=1 μm). 15. Anterior view of L. eupora showing the operculum and flagella with granular particles (Scale bar=2 μm).

Saccinobaculus sp. and Barbulanympha sp. (via)

The oxymonad protist Saccinobaculus (foreground, at about 12 microns in diameter) orbiting the much larger parabasalid protist Barbulanympha (background, at about 100 microns in diameter), which is covered in a dense monolayer of rod-shaped symbiotic bacteria. From the hindgut of the wood-feeding roach Cryptocercus. Images by Kevin J. Carpenter. (More)

Dinoflagellates (via)

Dr Paul Hargreaves and Faye Darling call this electron microscopic image of dinoflagellates 'MiroMira2', but we think it looks like a couple of muffins. (More)

Ceratochoris horrida (via)

Trichomonas foetus (via)

Trichomonas foetus is a single-celled protozoan that infects the bovine reproductive tract and the intestinal tract of cats. Cows are infected by bulls that harbor the parasite on their foreskin. The resultant infection of cows can result in infertility, pyometra, and embryonic death and abortion. (More)

Stephanopogon sp. (via)

It closely resembles certain ciliates and was originally classified with them, but is now considered a flagellate. The cell is somewhat flattened, with multiple smooth flagella arranged in rows running from the front to the back, and has an anterior mouth supported by rods. They feed on bacteria, diatoms, and other smaller organisms. There are 2-16 nuclei, but they are not differentiated into macronuclei and micronuclei as occurs in ciliates. (More)

Phacus sp. (via)

[prettyprotozoa]

Identified as Prorocentrum gambierdiscus by original source; identified as Diplopsalis or Zygabikodinium by Dean Jacobson.

Coloured scanning electron micrograph (SEM) of the dinoflagellate, Prorocentrum gambierdiscus. Prorocentrum species produce okadaic acid, which is associated with diarrheic shellfish poisoning (DSP). Dinoflagellates are unicellular protozoans. About 90% are found in marine environments as plankton. They are characterised by the presence of two flagella (not visible). One flagellum beats back and forth, while the other is flat and ribbon- like, and works as a rudder to steer and rotate the organism. (via)
