research:Karenia Brevis a dinoflagellate

The Karenia Brevis dinoflagellate creates harmful and very toxic algae blooms called florida red tides. These unicellular organisms may be microscopic, but their toxins (brevetoxins) can kill large quantities of fish and make people very sick. Neurotoxic shellfish poising (NSP) is caused by the ingestion of shell fish such as clams and mussels that have been contaminated with brevetoxins.
Symptoms found in humans may be:
-numbness of mouth, face, and limbs
-nausea
-vomiting
-headache
-slurred speech
-partial paralysis
-difficulty breathing
Brevetoxins lead to the death of numerous fish and animal mortalities.
The gulf coast is greatly effected by K. Brevis and Brevetoxins. The death of all the fish is less food for both people and larger fish, less bait, and causes sickness within people.
