Notes: target (A. sanguinea), 1 species in genus, annual, may be abundant, worldwide distrib., large-30-100um ⁴

30-100 µm(L)

Description ⁵

Despite its lack of thecal plates, a prominent feature helpful in identifying armored flagellates, A. sanguinea is relatively large and easily recognizable. Like most dinoflagellates, one flagellum is complex, wrapping around the equator of the cell in a groove. The other flagellum extends out from the cell to help aid its movement through the water. A. sanguinea’s most prominent features are the lack of a nuclear envelope chamber and the apical groove’s large, clockwise path when viewed from the front of the cell. These features, along with observations and data from LSU rDNA sequencing, recently helped declare a new genus for this species (Hansen & Moestrup).
