Wiredreports that the viral video reportedly of an "unknown lifeform" that was recorded in a sewer in Raliegh, North Carolina is a colony of tuibifex worms.
"They seem to respond to the light from the camera," says Ed Buchan, environmental coordinator at the Raleigh Public Utilities Department. "That light is pretty hot." Buchan also said, "We were surprised. We didn't know immediately what it was."
