Speculation on YouTube as to what it might be ranges from a marketing ploy to promote a new alien movie to undocumented life form to a sewer monster.But a sewer monster, it is not.The city of Raleigh says the video – of a 6-inch sanitary sewer line – was taken in April during an inspection of a privately maintained sewer line in Cameron Village.Ed Buchan, an environmental coordinator with the city's Public Utilities Department, says the mass is believed to be tubifex worms, which form clusters or colonies of about a half-inch to 1-inch in diameter.Thomas Kwak, a biology professor at North Carolina State University's Cooperative Fish and Wildlife Research Unit, however, says the so-called monster is actually a cluster of invertebrates called bryozoan, which are commonly found in both the sea and fresh water environments.
