We descend to an unknown and hostile world, where it is difficult to imagine life. A word forbidden to plants, in which some animals, however, have managed to thrive by exploiting the few sources of energy channeled from the outside.

The troglobian fauna shows the highest rates of endemics known and houses within it a large number of primitive forms, real living fossils that engage the evolutionary history of life on the planet. Bats, insects, millipedes and spiders make up this cast of original forms of life, unique in its evolutionary isolation.
This is a wonderful world as austere, where time is lost in the darkness for make perennial the beings living there.
