Amylax triacantha

Amylax triacantha are small solitary flagellates, 42-60μm long with an apical horn extending from the concave epitheca and one or more antapical spines originating from the terminal end of the hypotheca. Amylax triacantha have a displaced cingulum, and are widest posteriorly. These cells have chloroplasts and thin, reticulated theca. Amylax triacantha are found in coastal cold waters in both the Pacific and Atlantic.
