Spaghetti Worms?

[lilming]

I noticed long sticks of sand coming out under my rocks in the sand the other day. When I pick up the sticks of stand, it crumbles but have a gooey texture to them. Today I found what was causing them. I think its a spaghetti worm? I see a LOT of tentacles sticking out reaching for the sand and spitting back out darker "sand".
