Which is the saltiest sea in the world?

it depends I suppose if you class the Dead Sea as a sea. It's really a lake. But anyway, the Red Sea is certainly not the "saltiest body of water on earth" as claimed in the description.

A bad question. "The Dead Sea is the saltiest body of water in the world, with a salinity of 30%. This is almost 10 times saltier than the ocean. The Dead Sea's high salt concentration makes it so dense that people can float without effort." The Mediterranean Sea is saltier than the Red Sea.

Wiki claims that it "is one of the saltiest bodies of water" not that it is the saltiest. Further it uses "per mille" not percent, which means the figures compare as 3.6 - 4.1% to the Dead Sea's 33.7% and Ethiopia's Gaet'ale Pond and 43.3%. However at 4.1% it is the saltiest body of "open" water (therefore sea) as the rest are endorheic lakes.
