From regional or thematic species database. Distribution Dinophysis acuminata is widely distributed from cold to warm waters of both hemispheres. Its presence in the Mediterranean Sea has not been convincingly demonstrated. [details] Harmful effect The main agent of DSP outbreaks in European Atlantic coasts.

Dinophysis acuta was more susceptible to photodamage under high light intensities (370–650 μmol photons · m −2 · s −1) than D. acuminata but survived better with low light (10 μmol photons · m −2 · s −1) and to a prolonged period (28 d) of darkness.

The difference between these two classes was a 70 bp deletion, indicating the shorter product might be a pseudogene. Dinophysis is one genera responsible for Diarrhetic shellfish poisoning (DSP), a global illness with incidences of outbreak or high toxicity occurring in North America, western Europe, east and southeast Asia, South America, Latin America, South Africa, New Zealand, and Australia.

The dynamics of Dinophysis acuminata and its associated diarrhetic shellfish poisoning (DSP) toxins, okadaic acid (OA) and dinophysistoxin-1 (DTX1) as well as pectenotoxins (PTXs), were investigated within plankton and shellfish in Northport Bay, NY, USA, over a four year period (2008–2011). Over the course of the study, Dinophysis bloom densities ranged from ~104 to 106

The genus Dinophysis includes both phototrophic and heterotrophic species. Dinophysis acuminata preserved in Lugol’s iodine solution.

Dinophysis acuminata preserved in Lugol’s iodine solution. Photo taken during the National Center for Marine Algae and Microbiota Harmful Algae Taxonomy Course at Bigelow Laboratory in 2019 (A. Pappas, 2019). Dinoflagellates are a group of microscopic, mostly unicellular aquatic protists that are members of the plankton community.
