Light micrographs of the dinoflagellates Gymnodinium acidotum and Dinophysis fortii. (a) G. acidotum harbors blue-green-colored, transient plastids that are derived from a Chroomonas-like cryptophyte alga. (b) D. fortii periodically captures cryptophyte-derived, orange-colored plastids from the 'photosynthetic' ciliate Myrionecta rubra. Scale information for (b) is not available. A normal cell of D. fortii is typically 51 to 83 μm long and 41 to 58 μm wide. (a) Photo courtesy of Lee W Wilcox and Gary J Wedemayer; (b) photo courtesy of Kazuhiko Koike and Kiyotaka Takishita.
