What type of phytoplankton is Dinophysis?
Dinophysis is a genus of dinoflagellates common in tropical, temperate, coastal and oceanic waters.
Is Dinophysis a protist?
Dinophysis acuta is a marine unicellular protist, and is the largest among Dinophysis. It is an armoured species with a distinct body covering called theca or test.
Is Dinophysis algae?
The toxic dinoflagellate alga Dinophysis threatens human health and coastal economies through the production of toxins which cause diarrhetic shellfish poisoning (DSP) in humans.
What is Dinophysis spp?
Species Distribution: Dinophysis species are dinoflagellates that produce the toxin okadiac acid and dinophysis toxins. These species are generally found worldwide, including populations in North America and along the northeast coast of the United States and the Gulf of Mexico.
What type of organism is responsible for diarrhetic shellfish poisoning?
Diarrhetic Shellfish Poison (DSP) is a marine biotoxin toxin produced by the dinoflagellate Dinophysis, which is a type of naturally occurring microscopic algae. Shellfish eat these algae and can retain the toxin.
Where does Dinophysis acuminata live?
Dinophysis acuminata is a marine plankton species of dinoflagellates that is found in coastal waters of the north Atlantic and Pacific oceans.
What eats Karenia brevis?
brevis. Fish species through the food chain are impacted, up to and including large predatory species such as sharks, as well as species typical in human consumption.
What causes paralytic shellfish poisoning?
Paralytic shellfish poisoning is caused from the ingestion of toxin-contaminated bivalve shellfish and crustaceans. Algal blooms of dinoflagellates, usually during the warmer months of June to October, result in toxin accumulation in filter feeders such as bivalves.
What organisms are affected by DSP?
U.S. Finfish and Shellfish Vectors of DSP
| Geographic Area | Affected Organisms* |
|---|---|
| NE Atlantic Coast Washington California Gulf of Mexico Gulf of Maine | Mussels Scallops Clams Oysters |
Where does diarrhetic shellfish poisoning occur?
Diarrhetic (or diarrheal) shellfish poisoning occurs from ingesting shellfish (such as mussels, cockles, scallops, oysters and whelks) that contain toxins.
