sewer life.

30 Jun

“Best explanation I’ve heard so far is some form of bryozoan, an extremely primitive form of animal life. Freaky deaky!”

“Doesn’t look cnidarian or bryozoan. I don’t see symmetries but rather opportunistic irregular (& soft & fleshy) striata for sessility and movement”

UPDATE: Video removed. Let your theories begin.

NEW UPDATE: New vid added.

And explanation:

“They are clumps of annelid worms, almost certainly tubificids (Naididae, probably genus Tubifex). Normally these occur in soil and sediment, especially at the bottom and edges of polluted streams. In the photo they have apparently entered a pipeline somehow, and in the absence of soil they are coiling around each other. The contractions you see are the result of a single worm contracting and then stimulating all the others to do the same almost simultaneously, so it looks like a single big muscle contracting. Interesting video.”
