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:

Dinoflagellate species of Dinophysis are obligate mixotrophs that require light, nutrients, and prey for sustained growth. Information about their nitrogenous nutrient preferences and their uptake kinetics are scarce. This study aimed to determine the preferred nitrogen sources in cultures of D. acuminata and D. acuta strains from the Galician Rías Baixas (NW Spain) and to compare their Okadaic acid and Dinophysis Dinoflagellates, Dinophysis acuminata and D. ovum, were cultured using a three stage feeding system: cryptophytes were fed to ciliates, which were fed to the mixotroph Dinophysis. Culturing experiments were conducted to determine environmental drivers of growth and toxin production (okadaic acid, dinophysistoxins, pectenotoxins). Dinophysis caudata actively ingested the cytoplasm of the prey through the peduncle. Dinophysis caudata grew at a growth rate of 1.03 divisions day-1 when supplied with M. rubra as prey, Dinophysis is a genus of dinoflagellates common in tropical, temperate, coastal and oceanic watersHallegraeff, G.M., Lucas, I.A.N.

Pappas, 2019). 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. Dinophysis fortii is a photosynthetic dinoflagellate. It reproduces asexually by Close Binary fission. A form of asexual reproduction where one cell divides into two identical cells.

acuminata, Dinophysis tripos, Dinophysis caudata and Dinophysis fortii are included in the IOC-UNESCO reference list of toxic microalgae (Zingone and Larsen, A regular monitoring on phytoplanktons at 10 m and 24 m depths of Okkirai Bay revealed that the occurrence of a dinoflagellate Dinophysis fortii paralleled well, The new compounds were isolated as minor components from a large collection of a Dinophysis acuta-dominated bloom obtained from Skjer, Sognefjorden, Diarrhetic Shellfish Poisoning Toxins (DSTs) are produced by the marine dinoflagellate, Dinophysis. DSTs can bioaccumulate in shellfish and cause Dinophysis.

However, since D. caudata was also present in the same sample, the species responsible for DSP cannot be ascertained. 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.

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.

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.
