Division The toxic dinoflagellate alga Dinophysis threatens human health and coastal economies through the production of toxins which cause diarrhetic shellfish poisoning (DSP) in humans. Although North American waters have historically been free of Dinophysis blooms and associated DSP poisoning events, Dinophysis species can be a common component of marine phytoplankton. Increasing documentation of Dinophysis acuta, 75µm by 35µm. are a species of dinoflagellate which are widely distributed but commonly found in cold and temperate neritic waters (Ehrenberg, 1839). “Dinoflagellate” means “whirling flagella”, although Dinoflagellates actually have two flagella that can be used to turn and provide forward movement.

Only trace amounts of OA and DTX1 were detected in D. caudata.

Dinophysis is a genus of dinoflagellates common in tropical, temperate, coastal and oceanic waters. It was first described in 1839 by Christian Gottfried Ehrenberg. Dinophysis are typically medium-sized cells (30-120 µm). The structural plan and plate tabulation are conserved within the genus.

Dinophysis: Division: DINOPHYTA (PYRROPHYTA) Class: Dinophyceae: Order: DINOPHYSALES: Trophy: MX: Geometric shape: Formula: p/6*l*d1*d2 Övrigt: Dinophysis-dinoflagellater finns främst i saltvatten över hela jorden, men de kan även finnas i små mängder ända upp i Bottenviken. Med hjälp av sina flageller kan dessa organismer simma , och de kan både äta mat från vattnet och skapa sin egen näring genom fotosyntes.
