Akashiwo (ah-cash-ww-woe) sanguinea (previously Gymnodinium sanguinea) has an 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. This species is flattened, and has plastids. Phase contrast microscopy. data on this strain.

Akashiwo (ah-cash-ww-woe) sanguinea (previously Gymnodinium sanguinea) has an 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. This species is flattened, and has plastids. Differential interference microscopy. data on this strain.

This is large Akashiwo species with a pentagonal cell. The apex is rounded. The sulcus deeply excavates the hypotheca. A. sanguinea contains chloroplasts which radiate from the centre of the cells. A. sanguinea has been associated with fish kills and might be toxic.
