Sea of Cortez Worm

I have been unable to find a resource for this one....any guesses out there?

Sea of Cortez (Midriff Islands)

hi Marli --

It's family Sabellidae. There are only a few genera of sabellids, let along species, that can be identified from pictures. I can see two radioles (the feathery plumes that make up the crown) sticking up while the other radioles are curled down. Do you have other pics clearly showing the tips of the two upright ones? I think I see small black swellings at the tips which would be eyes which would make this the genus Megalomma. If the tips are bare you'll have to be satisfied with just the family name.

Cheers, Leslie

Hi Leslie,

There are indeed two black tips, so at least I have a genus. Thanks! There are more mysteries to come...sorry, not worms.

Cheers,
