Dinophysis is a genus of dinoflagellates[1][2][3] common in tropical, temperate, coastal and oceanic waters.[4] It was first described in 1839 by Christian Gottfried Ehrenberg.[5]
Dinophysis are typically medium-sized cells (30-120 μm).[5] The structural plan and plate tabulation are conserved within the genus.[4]Dinophysis thecae are divided into halves by a sagittal fission suture.[4] There are five types of thecae ornamentation in this genus,[4] and those are a useful character for species identification.[4]Dinophysis mainly divide by binary fission.[4]
Dinophysis chloroplasts are usually rod-shaped or granular and yellow or brown colored.[4] Some Dinophysis spp. take up kleptoplastids when feeding. Toxic Dinophysis produce okadaic acid, dinophysistoxins, and pectenotoxins, which inhibit protein phosphatase and cause diarrhea.[6]
