Type of worm?

[hdtran]

I found this worm in my substrate. An ID would be greatly appreciated (I don't need genus/species; I would like a 'common' name, e.g. it's not a feather duster, it's not a bristleworm, it's a ...)

The picture is of the worm between the glass and the substrate. Its diameter is on the order of 1/16 to 1/8 of an inch.

Thanks!

Would the redoubtable John Brandt speculate that this is perhaps a peanut worm? He's been spot on on all the other ID's (good call with the limpet, I never thought limpets had external mantles...).

And, happy new year everyone!

Hy, don't you know I've been avoiding this one? :wink:

I don't know what this is. It would help if we could see more of it. Next time you find it gently lift it out of the sand and take a bunch of pictures. Focus on the head too.

It looks unsegmented. It could even be a flatworm.

Hey, John,

I'm not much of a photographer (it's not the camera, it's the operator :wink: ), but I'll do my best.

It ingests substrate, and it's unsegmented. The head looks like it has frilly short tentacle thingies. It's always under the substrate; I spotted it because it was against the glass. It's now away from the glass, and I imagine 1" under the substrate.

That said, you are spot on with just about all the ID's.
