The Dead Sea

The Dead Sea, also called the Salt Sea, is a salt lake bordering Jordan to the east and Israel and the West Bank to the west. Its surface and shores are 423 metres (1,388 ft) below sea level, the lowest elevation on the Earth's surface. The Dead Sea is 377 m (1,237 ft) deep, the deepest hypersaline lake in the world. With 33.7% salinity, it is also one of the world's saltiest bodies of water.  It is 8.6 times saltier than the ocean. This salinity makes for a harsh environment in which animals cannot flourish, hence its name.  The sea has a density of 1.24 kg/L, which makes swimming similar to floating.
