Brown Tide

Caption

The brown tides caused by Aureococcus anophagefferens -- like the one above in Long Island, N.Y. -- do not produce toxins that poison humans, but the long-lasting blooms are toxic to bivalves and have decimated sea grass beds and shellfisheries leading to billions of dollars in economic losses.
