> Dear Olev, I think this is Pectinariidae.
> According to my data the tube of Terebellidae g. Pista  (it consists of
sand particles  glued by organic cement)  are combined by sand particles
oriented   mainly transversally, I e. their long narrow sides lie across
the tube (its surface looks “banded”) despite of the Pectinaria  tubes,
characterized  by  chaotic “mosaic” surface.
> Here is photo of Pista flexuosa and Pectinaria koreni tubes. Some photos of
> Pectinaria tube I will be able to  send you after  23 of October, ( My  SEM
> time scheduled on the end fo October).
