Karenia Brevis

Dinoflagellates

Karenia brevis is a species of marine dinoflagellate best known as the primary organism responsible for red tide blooms in the Gulf of Mexico, particularly along the coasts of Florida. When conditions favor its rapid reproduction, it can turn coastal waters a reddish-brown color and release brevetoxins, potent neurotoxins that kill fish in large numbers, contaminate shellfish and cause respiratory irritation in humans exposed to sea spray near an active bloom.

  • Section: Impact on human health and activities
    The brevetoxins released by K. brevis can be found in the flesh of shellfish during Florida Red Tides, potentially causing a condition known as Neurotoxic Shellfish Poisoning (NSP) in humans. Although no recorded human deaths have occurred from NSP, the poisoning does result in nausea, vomiting and a variety of neurological symptoms.
