This also reminds me of Cuatro Ciénegas Basin in Mexico. It is studied because its life forms are directly connected to the Oxygenation period our Earth went through. Below the surface, there are a lot of creatures that cannot exist anywhere else (that we know of) on Earth, and that thrive in this environment that would kill just about any other life form. They are considered some of the most primitive oligotrophic life we know of still around today. https://en.wikipedia.org/wiki/Cuatro_Ci%C3%A9negas#Cuatro_Ci%C3%A9negas_Basin https://en.wikipedia.org/wiki/Cuatro_Ci%C3%A9negas#Cuatro_Ci...
