hi drift tube cluster unriddlers:


All previous suggestions are unacceptable.


Since the beginning of the discussion I have been pretty sure that the  
photo (although of poor resolution) shows a a cluster (possibly even a  
colony) of Stephanoscyphistoma which is the benthic polyp stage of  
Scyphozoa Coronatae (Cnidaria). The benthic polyps of Coronatae are  
characterized by a tube sheathing of the type shown by the photo.

I would have prefered to have this identification sent to ANNELIDA by  
the true specialist of this groupe, Gerhard Jarms of Hamburg  
university, Germany:
I sent him the photo but presently he seems unavailable. He might even  
have a guess concerning the genus, especially if he could have high  
resolution photos providing more details of the tube structure. Perhaps  
you will receive his more authorized opinion later, via ANNELIDA.

Stephanoscyphistoma (contrary to Stephanoscyphus) is not a generic name  
but designates the tube producing benthic polyp stage of Coronatae, in  
general. This term has been introduced by Gerhard Jarms. In the older  
literature such tubes (sheltering the polyps) have widely been reported  
as Stephanoscyphus.
Stephanoscyphistoma can be found worldwide, from shallow to deep water  
and correspond to various genera. Some species are colonial and some of  
these live inside sponges. Solitary Stephanoscyphistoma are most common  
in submarine caves of the Marseille are (NW Mediterranean, France).  
Bernhard Werner benefited of this easy access for doing some of his  
live cycle investigations.
Stephanoscyphistoma (solitary ones) are common also on slags from coal  
burning ships all over the oceans, especially in deep water.

Detailed studies on the life cycle (some species have it shortened:  
direct develoment, no more medusa stage), tube structure and taxonomy  
have been published since the 1960s, in particular by Bernhard Werner  
(then Biologische Anstalt Helgoland, Hamburg), followed by Gerhard  
Jarms. A few papers deal with the symbiosis of colonial forms with  
(inside) sponges.
