Why Is The Ocean Salty?
10. Underwater Brine Pools
In some parts of the world are a curious phenomenon known as brine pools. There are areas of water that are saltier than the surrounding water, causing it to sink to the bottom. The pools themselves look like lakes of water although they are already under water themselves.

Some of these pools are located on deep ocean floors, meaning it has only been relatively recently that we have discovered them. They do often create habitats for wildlife but many species need to be careful about swimming into the pool itself. The salinity here is so high that even sea creatures can be killed by it.
