A couple weeks ago I happen to watch a nature explorers show about
divers in the sinkholes and underground streams of Florida. Far below
what should have been the kill line, they found crustaceans, etc., and
further down found a cave with a fresh/saltwater split separated by a
thin layer of bacteria that was providing the sulfur (I think) based
food for the local population. It was just a milky film extending
horizontally throughout that level.
