There is no doubt that this is a sipunculan. It looks like a juvenile
Sipunculus to me, probably S. nudus, but without taking a look at the
actual specimen, I cannot tell with certainty. It could also be a
Golfingia or Nephasoma. Take a close look at the body wall - if it is
smooth and you can see criss-crossed longitudinal and circular muscle
bands, forming little squares, it is a Sipunculus. If it has small hooks
on the introvert it is something different.

The attached picture is of an invertebrate (approx 5mm length) that
turned up in a littoral muddy sand sample take near to Zostera beds on
the east coast of Jersey, Channel Islands (English Channel).
I am pretty certain that it is not an annelid but I wondered if anyone
has encountered something similar the course of their research? It
reminds me of a sipunculan but I can't find a match in the literature I
have available to me. Any thoughts will be gratefully received.
