Amphidinium (am-fee-din-ee-um) glabrum Hoppenrath & Okolodkov 2000. The images show colourless cells in ventral view. The cingulum is near the anterior end of the cell and descending. The epicone is asymmetrical and the apical groove is visible. The nucleus is near the posterior end of the cell.
-
This is Amphidinium cf. glabrum in that it looks like but is not fully identical with the usual concept of this species.

Karlodinium (car-low-din-ee-um) micrum (previously Gyrodinium galatheanum) has a equatorial flagellum lying in a groove (girdle or cingulum) near the centre of the cell and a second flagellum trailing behind the cell and arising in a longitudinal groove or sulcus. The large gray area posterior to the girdle is the nucleus. The orange element is probably a residue from ingested food (Rhodomonas). Phase contrast microscopy.

The granular region in the centre of the cell is the nucleus. Differential interference microscopy.
-
The epitheca of K. glaucum is both longer and wider than the hypotheca. The cingulum is displaced by about 4-5 times.

Gymnodinium (jim-no-din-ee-um), a so-called typical dinoflagellate. Most dinoflagellates have two flagella and they lie in grooves in the cell surface. The flagella are not evident here, but the grooves are. There is an circumferential groove (the girdle or cingulum) which wraps around the cell, and a longitudinal groove which extends from the point of flagellar insertion towards the back of the cell. This is an autotrophic dinoflagellate with numerous plastids with chlorophylls a and c. Also with an eyespot. Differential interference contrast.

Gymnodinium (jim-no-din-ee-um), a so-called typical dinoflagellate. Most dinoflagellates have two flagella and they lie in grooves in the cell surface. The flagella are not evident here, but one groove -the circumferential groove - is. This is an autotrophic dinoflagellate with numerous plastids with chlorophylls a and c. The nucleus is the granular structure in the upper (epicone) part of the cell. Differential interference contrast.

The flagella are not evident here, but one groove -the circumferential groove - is., and the second (trailing) flagellum can be seen extending out the back of the cell. This is an autotrophic dinoflagellate with numerous plastids with chlorophylls a and c. Phase contrast.
