New ecosystem found in cave

One hundred meters below the surface of the earth, an ancient and thriving cave ecosystem was found recently. So far, scientists have found eight species living in the cave, and all eight are previously unknown.

The cave includes marine and freshwater portions, and is probably 5 million years old, said scientist Hanan Dimantman.

I guess there is something new under the sun, although in this case it's hidden under 100 meters of rock.
