Scientists find methane-fuelled ecosystems in Mexico's caves
Scientists with the US Geological Survey have found an ecosystem thriving on methane gas in the flooded caves of Mexico's Yucatan Peninsula. Methane, which forms in soils and usually migrates upward, was found to go deeper into the water and caves beneath the jungles. The methane is consumed by bacteria, which then fuel an ecosystem dominated by crustaceans including shrimps.
