What is the scientific Name for red tide, and where does it happen?
In the trade its referred to as an HAB--Harmful Alge Bloom. Occasionally, the algae grow very fast or "bloom" and accumulate into dense, visible patches near the surface of the water. "Red Tide" is a common name for such a phenomenon where certain phytoplankton species contain reddish pigments and "bloom" such that the water appears to be colored red. The term "red tide" is thus a misnomer because they are not associated with tides; they are usually not harmful; and those species that are harmful may never reach the densities required to discolor the water.





Unfortunately, a small number of species produce potent neurotoxins that can be transfered through the food web where they affect and even kill the higher forms of life such as zooplankton, shellfish, fish, birds, marine mammals, and even humans that feed either directly or indirectly on them.

Reply:The most common cause of toxic red tides in Texas and Florida is Gymnodinium breve, a marine dinoflagellate. Florida has experienced a Gymnodinium breve red tide 23 out of the past 24 years. This species of red tide has been experienced at least once by all the Gulf of Mexico states and has been transported up the Atlantic coast all the way to North Carolina.
