What is the only sea in the world that has no land coastline?
The Sargasso Sea is a region of the North Atlantic Ocean distinguished by the absence of land boundaries. Instead of being enclosed by coastlines, it is defined by four major ocean currents that form part of the North Atlantic subtropical gyre. The sea is named after floating Sargassum seaweed, which provides food, shelter and breeding habitat for many marine organisms. Unlike coastal seaweed attached to the seabed, this seaweed floats freely at the surface. The Sargasso Sea is particularly important in the life cycle of European and American eels, which migrate across vast distances to reproduce in the region. Its calm-looking waters and floating vegetation have attracted the attention of sailors and scientists for centuries. Today, the area faces environmental pressures from plastic pollution, changing ocean conditions and shipping activity, making its protection important for marine biodiversity and ocean research.
