For example, in graduate school, I studied the behavior of
Karenia brevis. Every other marine species we looked at went up to the sunlight in the day and down to feed on nutrients at night.
That's an environmental ecological response to high nutrients." Scientists widely agree red tide, made up of
Karenia brevis algae, gets seeded offshore at the bottom of the Florida shelf, then carried inshore by bottom currents.
This red tide is caused by a tiny algae called
Karenia brevis, which produces an often-deadly toxin.
These include Blue Green algae or cyanobacteria (responsible for the current problem on the east coast of Florida) and "Red Tide" algae or dinoflagellates (such as "
Karenia brevis" responsible for algal blooms in the Gulf of Mexico as well as "Alexandrium fundyense" causing red tides along the Atlantic Coast).
On parts of the Gulf Coast, periodic blooms of red tide (
Karenia brevis) may kill fish and sometimes manatees with neurotoxins.

Entre las especies que se han reportado como productoras de toxinas en Mexico se mencionan a Gymnodinium catenatum Graham y
Karenia brevis (Davis) Hensen et Moestrup, son atecadas o desnudas, y Pyrodinium bahamense var.

In the fall of 2007, Sosik and Olson collaborated with biological oceanographer Lisa Campbell at Texas A&M University to deploy the device in the Gulf of Mexico to look for seasonal blooms of toxic algae called
Karenia brevis. The algae accumulate in filter-feeding shellfish, making them dangerous for human consumption.
