  • Gonyaulax apiculata
  • Gonyaulax polygramma Stein 1833[1]

Gonyaulax is a genus of Dinoflagellates with the type species Gonyaulax spinifera (Claparède et Lachmann) Diesing. Gonyaulax belongs to red dinoflagellates and commonly causes red tides.[4]

The plate formula in the genus Gonyaulax Diesing was redefined as Po, 3’, 2a, 6”, 6c, 4-8s, 5’”, 1p, 1”” [5]

Gonyaulax spinifera has been related to production of Yessotoxins (YTXs), a group of structurally related polyether toxins, which can accumulate in shellfish and can produce symptoms similar to those produced by Paralytic Shellfish Poisoning (PSP) toxins.[6]

All species are marine, except for one freshwater species Gonyaulax apiculata.[5]

It previously included several species, which are now considered to belong to a separate genus, e.g.:[5]
