Well greenIn the vastness of this deep well over 100 meters is easy to miss the proportions. You see the caver who is climbing abseiling?
Medusa underground In a cave in the mountains of the French Montagne Noire, a Spectacular "jellyfish" red calcite - stalactites of this mineral areformed by the precipitation of calcium carbonate present in water droplets that descend into the caves.

Aided by the darkness of the caves and their relative abundance larvae make walls glow of the filaments. And sticky.
