A = Two cells at different focal planes (BF); B = Chloroplasts in epifluorescence microscope. Photographer/artist Mats Kuylenstierna. Dinophysis norvegica Claparède et Lachmann 1859. A = Two cells at different focal planes (BF); B = Chloroplasts in epifluorescence microscope Several studies have proved that some Dinophysis species are capable of ingesting particulate organic matter besides of being photosynthetic, a form of nutrition termed mixotrophy. Phagotrophy may 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. T1 - Parasitism of Dinophysis norvegica by Amoebophrya sp in the Baltic sea.

The pigment composition of Dinophysis norvegica Ehrenberg from the central Baltic Sea differs from the normal pigment pattern found in dinoflagellates, which contain peridinin as a typical marker pigment. In D. norvegica isolated by cell fractionation of field samples, the major carotenoid was alloxanthin, a typical cryptomonad pigment. No evidence was found that the presence of alloxanthin Dinophysis norvegica in the Gulf of Maine, USA and Its Accumulation in Shellfish (2020). Toxins, 12(9), 533.
