worm?

[r1v2c]

I have this weird thing growing on a rock. It has a thin body and is about 1/4" long then it has 2 antenna like things that are also about 1/4". I tried take a picture but it's at a bad angle. Any ideas?
I'll try to move the rock and get a pick.

Still trying to get a pic ... it's a rock under other rocks. The thing I'm talking about doesn't move, I don't know if that helps with the ID.
