A video from a sewer below Raleigh is grossing people out in a viral way.

The video of quivering blobs is posted on youtube.com. From the information on the video, it was taken in April and is from a line under Cameron Village in Raleigh.

WRAL.com reports Raleigh officials say the mass is "believed to be tubifex worms, which form clusters or colonies about a half-inch to one-inch in diameter."

WRAL.com also reports a biology professor says the blob is byrozoan.

The American Heritage dictionary defines byrozoan as "any of various small aquatic invertebrate animals of the phylum Bryozoa that are capable of forming vast mosslike or branching colonies attached to seaweed or hard surfaces."

Whatever it actually is, one thing is clear: it's gross. You can check out the video by clicking on the related link below.
