Dear Paul,
This looks like a sipunculan to me (maybe a phascolosoma or Apionosoma) with
its crown of tentacles at the tip of the introvert. Another possibility is
that it may be an echiuran.
Pogonophora<http://wapedia.mobi/en/Pogonophora_%28worm%29>,
Echiura <http://wapedia.mobi/en/Echiura> and
Sipuncula<http://wapedia.mobi/en/Sipuncula>,
previously regarded as separate phyla, are now regarded as sub-groups of
polychaetes.
Please do check if there are minute hooks surrounding the oral tentacles.
Best,
Naveen.
