Dinophysis norvegica is one of the most abundant dinoflagellates in the open Baltic Sea in the summer and subsurface blooms of this species is a recurrent phenomena in the area (Carpenter et al., 1995, Gisselson et al., 2002, Salomon et al., 2003), however, little is known of its mode of nutrition. Dinophysis norvegica is a species of dinoflagellate most commonly associated with diarrheal shellfish poisoning.

A closer look in the microscope revealed large amounts of bundles of A. flos-aquae and numerous cells from of the dinoflagellate Dinophysis acuminata (Fig. 5). Dinophysis acuminata is a marine plankton species of dinoflagellates that is found in coastal waters of the north Atlantic and Pacific oceans. The genus Dinophysis includes both phototrophic and heterotrophic species. D. acuminata is one of several phototrophic species of Dinophysis classed as toxic, as they produce okadaic acid which can cause diarrhetic shellfish poisoning (DSP). Dinophysis norvegica var.

Dinophysis norvegica (Dinophyceae), more a predator than a producer? Carvalho, Wanderson (author) Högskolan i Kalmar,Naturvetenskapliga institutionen Minnhagen, Susanna, 1977- (author) Högskolan i Kalmar,Naturvetenskapliga institutionen,Marine Ecology Granéli, Edna (author) Högskolan i Kalmar,Naturvetenskapliga institutionen,Marine Ecology Our main conclusion is that D. norvegica, and probably all other species from the genus Dinophysis, is mainly phagotrophic and feeds on a larger prey than T. amphioxeia. Autotrophy through kleptoplastidy would be a secondary feature used as a complementary or short-term survival strategy. Dinophysis norvegica Claparède et Lachmann 1859.
