The Dead Sea (, , "Sea of Salt", also , , "The Sea of Death", and ), also called the Salt Sea, is a salt lake bordered by Jordan to the east and Israel and the West Bank to the west. Its surface and shores are below sea level, Earth's lowest elevation on land. The Dead Sea is deep, the deepest hypersaline lake in the world. With 34.2% salinity (in 2011), it is also one of the world's saltiest bodies of water, though Lake Vanda in Antarctica (35%), Lake Assal in Djibouti (34.8%), Lagoon Garabogazköl in the Caspian Sea (up to 35%) and some hypersaline ponds and lakes of the McMurdo Dry Valleys in Antarctica (such as Don Juan Pond (44%)) have reported higher salinities. It is 9.6 times as salty as the ocean. This salinity makes for a harsh environment in which animals cannot flourish, hence its name. The Dead Sea is long and wide at its widest point. It lies in the Jordan Rift Valley and its main tributary is the Jordan River.
