The algae turns the water toxic for marine life, and in recent weeks beachgoers have been horrified to find turtles, large fish like goliath grouper and even manatees wash up dead. In late July, a 26-foot long (8-meter-long) whale shark washed ashore on Sanibel Island, which is known for its pristine beaches. In places like Longboat Key, more than 5 tons of dead fish have been removed from beaches. This week, nine dead dolphins were found in Sarasota County, and marine biologists are investigating whether the deaths are related to red tide.
The Florida Wildlife Research Institute says the number of dead and stranded sea turtles is nearly three times higher than average. More than 450 stranded and dead sea turtles have been recovered in four affected counties this year, and the institute estimates that 250 to 300 died from red tide poisoning.
