Did a crab molt or get eaten?

[djryan2000]

I have a salt tank with emerald crabs and some hermits along with a Sally Lightfoot, decorator, neon dottyback and a clown fish. I had a long work day and didn't get to feed the fish when I usually would, and when I got home they were all asleep so I figured I'd wait until the morning. When I looked at the tank I found this:


Did one of my crabs get eaten?

Pic isn't showing. If you recently did a water change, it's probably a molt.

No water change. It's just a claw and 3 legs.
