Being English I don't recognize this particular worm, but over here Hermit Crabs regularly have lug-worms as "lodgers".Hey Incognita, and thank you for the reply.
Its hard to see in that video but I do not think it is one of its legs, It seems to have its own set of feelers and looks as if it might have been trying to pull in some on the brine shrimp that I had just added, I do also think its very odd that a crab would let a worm live with it.
I also managed to get a slightly better video
