Worm?

I noticed something on my rock that i have not seen before that looks like a worm, at first i thought it was the snail but i was wrong.Plz ID it, its in the center of the pic.

peanut worm, very ugly but a good guy to have around

Ty Little_Fish,i have a pic of another scallop or clam i think, donno if the pic is clear for u to see but its the best i could get.I had no clue it was there till i saw it open up a tiny crack then it closed when i moved closer.

Hard to tell with the second pic -- maybe a barnacle of some sort. If it looks like a clam and opens and closes, it appears to be some sort of bivalve, and is nothing to worry about.

Ty Biff i think its a clam been looking at pics of them u right no worries here.
