Sinophysis (sine-o-fi/fu-sis) ebriolum (Herdman) Balech 1956. The image on the left shows a cell in right lateral view. The cell is laterally compressed. The epicone is much smaller than the hypocone. The image on the right shows a cell in a mid-focal plane. The cells contain no plastids. The cells are thecate and have cingular lists.
-
Sinophysis (sine-o-fi/fu-sis) grandis Hoppenrath 2000. The image shows a rectangular cell in left lateral view. The cell is laterally compressed. The epicone is much smaller than the hypocone. The cell contains no plastids, but different coloured food particles are visible. The cell is thecate and has cingular lists.
-
Dinophysis (die-know-fie-sis), common dinoflagellate in marine water column. This individual is clearly heterotrophic. Differential interference contrast.
-
Sinophysis microcephalus observed in marine muds and sandy sediments in the vicinity of Broome, Western Australia in September 2003. This image was taken using phase contrast optics. This work was supported by the Australian Biological Resources Study.

Sinophysis (sine-o-fi/fu-sis) stenosoma Hoppenrath 2000. The image shows a cell in right lateral view. The cell is laterally compressed. The epicone is much smaller than the hypocone. The cell contains no plastids. The cell is thecate and has cingular lists.
-
D. acuminata has an oval cell shape. The posterior end of the theca can bear small teeths. The left sulcal list is well developed and of a similar depth along its length. The pore structure is usually finer than in species such as D. norvegica, but is variable.
