Red Tide

Neurotoxins ***** Red pigmented algae contain poisonous Neurotoxins.
Neurotoxins caused nerve poisoning. Vomiting, headache,difficulty in breathing are common features.
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.
Scientists now prefer the term, HAB, to refer to bloom phenomenon that contain toxins or that cause negative impacts.
