The ocean is a strange and enchanting place. But one of the weird facts about the ocean is that there are actually underwater lakes and rivers. Yes, you read that right. Water located underwater. But how? When seawater seeps through thick layers of salt, the salt dissolves and forms depressions in the seafloor. That dissolved salt also makes the water in the area denser, and it settles into those depressions, causing lakes and rivers.
