The Martin County Sheriff’s Office believes a toxic algae bloom is to blame for killing one dog and making six others sick.
Nearly 4,000 dead fish were counted on Sanibel area beaches and parks.
Gov. Rick Scott's state of emergency could help local officials battle the toxic algae.
We observed large patches of marine macro-algae (Sargassum sp.) floating just offshore, drifting north, and getting stranded on the beach.
