University of A Karenia brevis bloom was observed on the West Florida Shelf in late 2011.. In the relatively nutrient-poor offshore waters of the eastern Gulf of Mexico, destructive blooms of Karenia brevis cause environmental and economic destruction. It is the organism responsible for the "Florida Red Tides" (coastal infestations), commonly referred to as red tides that affect the Gulf coasts of Florida and Texas in the U.S., and nearby coasts of Mexico. En esta última imagen, del Earth Observatory de la NASA, vemos la mancha que produjo una proliferación de Karenia brevis (> 1 millón de células/litro) en la costa de Florida en febrero de 2002…Y en 2005, pero en la costa mexicana de Tabasco, se detectaron hasta 8 millones de células por litro.

Tiene forma «aplanada» y al moverse recuerda a una moneda girando. They have Epoxide hydrolases (EH, EC 3.3.2.3) have been proposed to be key enzymes in the biosynthesis of polyether (PE) ladder compounds such as the brevetoxins which are produced by the dinoflagellate Karenia brevis.These enzymes have the potential to catalyze kinetically disfavored endo-tet cyclization reactions. Autonomous underwater gliders with customized sensors were deployed in October 2011 on the central West Florida Shelf to measure a Karenia brevis bloom, which was captured in satellite imagery since late September 2011.
