Deuterobiosphere the Chemosynthetic Second Biosphere of the Globe. A First Review

With the discovery of Ophel, a chemosynthesis‐based continental subterranean environment (Por 2007), it became evident that such environments, previously known only from the sea, are spanning the world as a parallel biosphere, the deuterobiosphere. In this preliminary contribution the different known biomes of the deuterobiosphere are reviewed and some general and comparative features are listed.
