What type of worm?

[Reefer37]

Found about 4 of these things in my sandbed coming out at night. White worms about 2 inches long or so.
Any one know what they are?

@Humblefish ~ do these look like anchor worms?

Dorvilleidae.

Yeah pretty sure that's it! Are these guys good or bad? Can't find a whole lot on them.

I believe KJ is right. My eyes totally fooled me in the pics. They’re good guys. They seem to disappear over time. Perhaps get eaten by other things.
