The body of water known for being the saltiest in the world is the Dead Sea. Located between Jordan and Israel, the Dead Sea has a salinity level of over 30%, making it almost ten times saltier than most oceanic bodies of water. This extreme salinity creates a unique environment where few organisms can survive, leading to its name. The mineral-rich waters are renowned for their therapeutic properties, attracting visitors worldwide for wellness and spa treatments. The Dead Sea also sits at the lowest point on Earth’s surface and contributes to significant geological and environmental studies.
