Taxacombers,
Here's thanks for an identification from a blogger whose reports are
well worth following.

Jenny Getsinger Is there some kind of burning test to tell
whether it's plant or animal? Like with fabric.

Susannah Anderson Great idea, Jenny! I burnt a tiny piece. It
smells like hair or feathers.

Fred Schueler any progress in figuring out what this is
(Polychaete tentacle of some kind?) I was once completely stumped by
an Edwardsia that didn't extend its tentacles -

Susannah Anderson No, getting nowhere fast. I thought of
polychaetes right away, and have gone through my encyclopedia several
times, looking at ones on this end of the continent. No luck so far,
but they are so diverse, I wouldn't rule them out.

Susannah Anderson When I burned a piece (about two rings from
the thick end), I crushed the stem in my fingers. It was crunchy, like
a thin eggshell. But it's not a tube like a tubeworm would build,
because the hairs sprout from little bases on this shell.

Susannah Anderson No, I thought of horsetails, because of the
rings, but otherwise, it doesn't work.

Jenny Getsinger I'm going to Marine section of VNHS (nature

Susannah Anderson There are only three crinoids from this
area in my Encyclopedia; very poor photos. One might possibly be
similar, if I can get a decent photo somewhere. I'll look.

Susannah Anderson I'd forgotten about the nature Vancouver
nights! I always intended to go, but it never works out. I'll see if I
can get a better look at the hair pores on the stem before you go.

Susannah Anderson I think that grey area on the second photo
would be a groove for transporting food. I thought, before, that it
was just some seaweed still stuck on, and I didn't want to break the
whole thing to be sure. But looking at it this closely, I can see that
it's integral to the tube.

Fred Schueler I probed the TAXACOM list with the query -
>> ...some sort of filament-bearing appendage?
Quoting Doug Yanega:

Quoting Tony Irwin:
> I'm fairly sure this is part of the pleopod (abdominal appendage) of

Susannah Anderson Thanks! That looks promising! The crinoids
turned out to be a dead end.
10 October at 23:32 · Like
Jenny Getsinger Okay, report from about half a dozen marine
biologists: a couple of no confidence votes on the crinoid idea; one
vote for a fishing lure; one for rotting horsetails; no one quite knew
what it might be. Still have not seen a good match in any of the
suggestions.

Fred Schueler if it were the external aspect of an entire
organism one of us would recognize it - it's got to be an "internal
external" fragment, and as Doug Yanega says "Crustaceans are
jam-packed with wacky appendages."

Susannah Anderson Fred Schueler, I don't have access to the
TAXACOM mailing list. Would you thank them for me? They were so very
helpful, and it's wonderful to find people who don't just say, "I
don't know," shrug and forget about it. And thank you for taking it to
them!

Jenny Getsinger Still no photos as detailed as yours show up
on image search of "pleopod"--you have done us a service by showing
this interesting body part.
