Have recently seen many small curved objects on the beach. They

Possibly some sort of protein binding it all together.

Each one is something like 75 mm long.

Across the beach there must be untold thousands:

I have tried image searches - Google, TinEye, Bing. Nothing I've found so far matches!

Any good ideas about how to preserve one - as a specimen? Obviously,
without changing its look. Has to be a simple technique using pretty
safe materials as it would have to be done on a public beach.


Worm casts?

What sort of worm?

And why have I not seen them, at least not in such profusion, before?
That is, there might have been a few, which I had not noticed, but now
they are absolutely everywhere and unmissable.


*Not* lugworm or razor shells.

There are lots of razor clams and their shells - but they are always there.


Well yes but I bet they all produce similar tubular casts.
