Dinoflagellates are perhaps best known to the public as the source of red tides leading to fish and other marine animal kills, as well as various types of human illness caused by their toxins: paralytic shellfish poisoning (PSP), neurotoxic shellfish poisoning, diarrhetic shellfish poisoning, and ciguatera (Landsberg, 2002; Hallegraeff et al., 2003).

Dinoflagellates are a diverse and abundant group of protists with complex interactions in the food web. They can form so‐called ‘red tides’ in coastal waters, a name that was given because of the changes in water colour observed at times.
