It's a harmless fireworm. It's not Hermodice, nor does it have anything to do with the loss of your clams. The only drawbacks are that it's ugly and the spines will irritate you if you touch them.

8'' isn't that big and size has almost nothing to do with whether it's safe or not. Harmless species are harmless regardless of how big they get.
