Biologist: clumps of algae along Captiva's east shore might smell bad, but aren't toxic

Over the past couple of weeks, massive clumps of floating algae have appeared in the waters along the eastern side of Captiva. It looks gross, and smells even worse. A biologist with the Sanibel-Captiva Conservation Foundation said the brown gunk is a cyanobacteria algae, but isn't toxic to humans.
