In this Jan. 2006 photo provided by Diane Littler, a unique new species of Sargassum is seen that scientists of the Conservation International Marine RAP (Rapid Assessment Program) expedition to Saba Bank Atoll, Netherlands Antilles, discovered along with more than a dozen other new species of seaweeds. Scientists have discovered what they believe is one new fish and at least 20 specimens of previously unknown seaweeds during the recent expedition.
