Most likely it's a polychaete worm.
Worms often build tunnels out of sand that are attached to rocks. They 'glue' sand particles together bit by bit with material they generate
internally. The head of the worm will appear from the opening usually when it's submerged. Some are filter feeders that look like feather dusters,
others have these long thin projecttions which search for food.
If you take a small pair of scissor and cut the tube lenghwise you will expose the worm and see for yourself.
That's what I think it is.

Interesting, some river insects do the same thing.

I'm at work right now and don't have the tools. I'll see if I can find the exposed animal from Google search and just paste it on the thread later
today.

Yes. The caddises.
You're right, come to think of it. The caddis creates a mucous web inside it's tube and then just ingests back the web with the trapped food inside.
Some worms do the same and create a small current from one end of the tube to the other. Food gets trapped and then it just ingests the entire mess,
food and 'mucous'.
Coevolution, they called it. Two unrelated species solving the same problem in the same way.

You seem to have exposed a tube anemone - not a worm - no segments to be a polychaete - did the "head" have purple colored tentacles? They are common
in tide pools, and mud flats - that's my guess!! Marv

What wine does one serve with this local cuisine? Some of my new wine snob friends have noticed my preference for Vino Ambar, aka cerveza. "Ambar"
goes well with any meat, fish, other.
BTW, great websites, love your ambitious projects.

The image is too blurry to see the presence or absence of segments.
The best thing to do, Susan, is to place your finger into it's mouth.
If you feel a sharp piercing sting - it's a worm.
If it's more of a 'sticky' feeling where the tentacles attach to your finger but there is no pain. Then it's an anemone.
