Atlantic Ocean encircled by the Gulf Stream, North Atlantic Drift, and North Equatorial Current. This population of seaweed probably originated from Tertiary ancestors on the European shores of the former Tethys Ocean and has, if so, maintained itself by vegetative growth, floating in the ocean for millions of years. Other species endemic to the Sargasso Sea include the sargassum fish, a predator with algae-like appendages who hovers motionless among the "Sargassum". Fossils of similar fishes have been found in fossil bays of the former Tethys Ocean, in what is now the Carpathian region, that were similar to the Sargasso Sea. It is

It contrasts with the North Atlantic Current because it is colder and contains less salt, having most of its tributary water coming from the slightly brackish North and Baltic seas, as well as the Norwegian fjords and rivers. It is, however, considerably warmer and saltier than the Arctic Ocean, which is freshened by the ice in and around
