“Red tide in Florida’s waters greatly affects both humans, buisnesses, and marine organisms. Red tide produces many toxins, both fatal and harmless, which affect us. K. brevis algae, in Florida, produces brevotoxins, which are amino based domoic acids. These brevotoxins can be potentially lethal. They can cause serious problems for both humans and marine oganisms.
Red Tide affects humans in more than one way. Red tide can cause respiratory problems, rashes, and irritation of the eyes, nose, throat, lips, tongue, and mouth. Also, through consumption of infected sea organisms, such as shellfish, humans may devlop serious illnesses, such as paralysis. Red tide also affects humans, by affecting our industries and businesses. Some of these industries are the tourist industry, commercial and residential fishing industry, hotel industry, and restaurant industry.
The effects of red tide are more serious for marine organisms. Red tide mainly affects sea turtles, filter fish, shell fish, and other similar types of fish. Red tide can cause a “rubber neck” condition, which can temporarily immobilize sea turtles, it can cause health problems, and it can be fatal. The brevotoxins released by K. brevis are potentially more dangerous and fatal for these marine organisms than for humans. "
