They had to screw around with Youtube... now you have to sign in thru Google!

 

I added Youtube to my Google account and it says that this is a "private video". :angry:

 

 

It worked the first time I tried it, then 10 minutes later when I went to show it to a friend it was like that. :angry:

The tubiflex worm videos don't really look like the sewer "creature" video. Am I wrong?

 

You just need to read the accompanying text --

 

Thanks for the video – I had not see it before. No, these are not bryozoans! 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.
