Akashiwo sanguinea (formerly called Gymnodinium sanguineum or Gymnodinium splendens) may form blooms, especially in summer to early fall. It is reported to kill fish and birds. Mortality may be due to clogging of shellfish gills, the production of surfactants, or to oxygen depletion when blooms decay.
