A Spongy, Frothy Foam
This spongy, frothy foam that would sit upon the water inside the cave is what would actually supply food particles to the eerie creatures that lived inside the cave. According to scientist Rich Bodin, the particles that float on the top of the water look like “floating film, which looks like wet tissue paper and can even be torn like paper.” He added to this explanation that it, “Contains millions upon millions of bacteria known as ‘autotrophs’.”
