Deep in Southern Mexico's jungle, the Villa Luz limestone caves support an ecosystem that thrives in a highly poisonous, acidic environment. This rare type of cave is found in few spots on Earth. Geologists and biologists wear gas masks and protective outerwear to explore the caves. All life forms, from microbial colonies to spiders, fish and bats, are interdependent upon the toxic soup of water, sulphur-oxide and hydrogen monoxide for survival.
