Marine Protected Areas (MPAs): Sargasso Sea. Photo 72: Map of Sargasso Sea. (NOAA Photo Library.) The Sargasso Sea is located entirely within the Atlantic Ocean and characterized by the presence of holopelagic Sargassum. Holopelagic Sargassum is free-floating algae that remains in the open ocean for its entire life cycle.
Sargassum also provides essential habitat for shrimp, crab, fish, and other marine species that have adapted specifically to this floating algae. The Sargasso Sea is a spawning site for threatened and endangered eels, as well as white marlin, porbeagle shark, and dolphinfish.
