Crab ID... plus one cool addition

[Janet Belanger]

Crab found it in the sump. Possible its been there for years, but more likely it came in on a rock from kp aquatics from on order over a year ago. Any thoughts what this might be?

Also, looks like a mussel from the same!! So cool!!

The crab is likely a no-no as the black tips are generally from group anthrax
Other pic is a bi valve which is often confused as a clam and is a reef safe filter feeder related to the scallop

I went back searching out my order for the rock, it was over 2 years ago that I acquired the little thing (maybe longer).

The crab is in the sump at this point, so I think we're good, right?
The mussel looking bi-halve isn't a mussel?

This same rock also came with a what I think are a couple species of thorny oyster, including one particularly stunning purple one. Several different feather dusters. All in all, good finds so far for sump critters.
