Snottite

Snottites or snotties are colonies of single-celled organisms that hang from the walls and ceilings of caves (similar to stalactites, but not hard). They digest sulfur componds in warm water in the cave, and slowly drip down from above. Snottites were recently brought to attention by a researcher, Penny Boston , studying them (and other organisms) in a toxic sulfur cave called Cueva De Villa Luiz (Cave of the Lighted House), in Tabasco, Mexico.
