What is this tube-like thing?

[archman]

Leslie will eventually pop by and figure out if it's a worm or not. There are some pretty fruity-looking marine worms that can get pretty big, and some species build a parchment-like outer lining.

It looks a lot like a cerianthid tube though.

Leslie would love to see it but nothing happens when she clicks on the attached thumbnails.....
Arch - "fruity-looking"?

You see! This is why taxonomists are NO FUN. Everything is taken literally. Now I need a cop-out... hmmm... maybe some free verse.

Oh Glycera! How bright your coelomic fluid. Juicy is your proboscis, not unlike a cherry tomato. Blessed crimson delight!

:cheering: Arch!

Okay, thumbnails are up....
Mr. X & Arch are right. it's the tube of the burrowing cerianthid anemone Pachycerianthus fimbriatus. Maybe there's even a anemone inside. The tube's made out of multiple layers of solidified mucus binding layers of silt. Lots of other critters burrow into it. I can remember what a nightmare they were to get in a sample because it was such a pain to sort out all the little animals. Plus all that silt always mucked up the sample.
