Segmented and wormlike

[Dan P]

Looks harmless, first time I’ve seen it. Part of the CUC?

Thanks!

That’s looks like a arm of a brittle star/mini mirror star

Dorvellidaes...

Cool video. I have not seen that before

 

[Crabs McJones]

I agree with Dorvilleidae

 

[Dan P]

Thanks for the ID, always fun to find something new in the tide pool.

Look like Syllid worm.

 

[reef lover]

Gonna need to see the whole worm then...if its syllid i do believe theyre unwanted in the reef...i googled many pics but didnt see a match...

 

[Dan P]

I’ve searched pics of both syllid and dorvilleidae worms, and haven’t found similar. Seems like I read similar things about syllids. Best I can get for a still shot.

 

[reef lover]

Better pic @KJ what do you think?

 

[reef lover]

Maybe to be safe remove if seen again

Possibly a Oenonid worm.

Seta look off to be a Syllid and the head doesn't work for an Oenone. Fairly certain it's a Dorvilleid but can't narrow it down to a genus. I suspect it preys on smaller polychaetes.

See the head is what made me think of Oenonid worm. Maybe it's the video (or me lol) but the head looks similar to this?

Is that an A iricolor? The head of that species looks similar but imo the OPs worm shares more characteristics overall with Family Dorvilleidae than Oenonidae

They do look similar. Here is a close up of another Oenonid. I will keep on researching lol. Maybe the OP can catch it so we can get a good look at it

 

[Dan P]

I’ll see if I can, maybe a trap of some kind. Might be able to get a better shot of it’s head if I see it again otherwise.

 

[Dan P]

First time I’ve seen anything since, these seem smaller but look similar.

 

[Lovemyreef2015]

Look up Lumbrineridae.
