The Great Wurm

The wurm is located deep underground, where there is no light. the creature is approximately 30ft long x 30 ft high x30 ft wide. it has no eyes that can be discerned. it has a mouth approximately 3 meters wide. it secretes a mucus that is acidic in nature, as all measuring devises after coming into contact with mucus, instantly disintegrated. how the cave floor remains untouched by this mucus is unknown. note any light shined on subject causes spasms and creature then lunges blindly toward light. as the viscosity or true acid composition cannot be found at this time. i ask that this beast be taken in to scp custody asap. as it poses a danger to cave spelunkers, and bats.
