Dinophysis tripos, Dinophysis caudata and Dinophysis fortii m are included in the IOC-UNESCO reference list of toxic microalgae (Zingone and Larsen, 2014) as putative or confirmed producers m ofDST.Nevertheless,inspiteofthecommonpresenceof Dinophysis spp. in Argentine coastal waters, confirmed reports of DSP are rather exceptional.
Several Dinophysis species produce diarrhoetic toxins (okadaic acid and dinophysistoxins) and pectenotoxins, and cause gastointestinal illness, Diarrhetic Shellfish Poisoning (DSP), even at low cell densities (<103 cells·L−1). They are the main threat, in terms of days of harvesting bans, to aquaculture in Northern Japan, Chile, and Europe.
Toxicity and toxin profiles are very variable This species can easily be confused with Dinophysis norvegica.D. acuta can be differentiated by its larger size and has its widest section below the mid-section of the cell (below two-thirds of the cell length), while D. norvegica is wide in the middle (Smithsonian 2011). Dinophysis dens Pav. Although published as part of an earlier work ("Identifying Marine Diatoms and Dinoflagellates," 1996), the 1997 compilation was used here. The editor's forword notes that "All nomenclatural novelties were validated in the original publications".
and their toxins on every US coast in recent years, the need to identify and monitor for problematic Dinophysis populations has become apparent. Here, we present morphological analyses, using light and scanning electron microscopy, and rDNA sequence analysis, using a ~2‐kb sequence of ribosomal Dinophysis spp. digest the prey nuclei and all other cell organelles upon ingestion (except the kleptochloroplasts) and they are therefore believed to constantly acquire new chloroplasts as the The first documented Dinophysis bloom from Greek coastal waters associated with a diarrhetic shellfish toxins outbreak was recorded in January 2000 during the HAB monitoring program in Thermaikos Gulf. A species with morphological features similar to D. acuminata Claparède and Lachmann dominated this bloom. Characterization of. Dinophysis.

Dinophysis species are armored dinoflagellates in the family Dinophysiaceae and, like other members of the family, have a consistent non-Kofoidian plate tabulation of 18 to 19 plates: four epithecal plates, two apical plates surrounding an apical pore, four cingular plates, four to five sulcal plates, and four hypothecal plates. Dinophysis (Dinophysis) Dinoflagellater är växtplankton med små piskliknande svansar som de simmar med och vissa har ett tjockt skal medan andra är mjuka. De med skal kallas även pansarflagellater och ibland bildar de kedjor bestående av 4, 8, 16 eller fler celler.
Däremot varnar informationscentralen i Västerhavet för växtplankton av släktet Dinophysis som lagras i blåmusslor och kan ge upphov till

Dinophysis caudata Saville-Kent, 1881 Species Overview: Dinophysis caudata is an armoured, marine, planktonic dinoflagellate species. It is a bloom-forming species associated with massive fish kills. It is commonly found world-wide in subtropical and tropical neritic waters. Taxonomic Description:
Dinophysis tripos Gourret, 1883 Species Overview: Dinophysis tripos is an armoured, marine, planktonic dinoflagellate species.

Dinophysis. Dinophysis spp.: This is a coastal ocean dinoflagellate that can contain little to no pigments.Dinophysis produces okadaic acid as well as other toxins that lead to diarrhetic shellfish poisoning, DSP. Primarily blooms subsurface in thin layers. Only occasionally seen in the Chesapeake Bay, it often blooms in the coastal lagoons of MD (January-June).
I think as of now no one really knows. 2004-04-01 Previous studies indicate differences in bloom magnitude and toxicity between regional populations, and more recently, between geographical isolates of Dinophysis acuminata; however, the factors driving differences in toxicity/toxigenicity between regions/strains have not yet been fully elucidated.
