Wood</A> who is an expert on freshwater bryozoa and an officer with the International Bryozoology Association.  I sent along the video and this was his reponse…</p> <BLOCKQUOTE><P>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 <A href="http://en.wikipedia.org/wiki/Tubifex_tubifex"><EM>Tubifex</EM></A>). 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.</P></BLOCKQUOTE></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://deepseanews.com/2009/06/creatures-from-the-sewer/"><div align="center"><embed src="http://www.youtube.com/v/6zfM2QS5tag&hl=en&fs=1&" height="329" width="400" wmode="opaque" quality="high" allowfullscreen="true" allowscriptaccess="always" type="application/x-shockwave-flash"></embed></div></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/9A7B0C5D-F4CE-4E46-97EB-2FD8C088798E/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
