Default Good crab or bad crab?

I have a crab that was a stowaway on my LR. He is the size of an emerald crab except he's orange. His arms are orange & brown striped w/black tipped pinchers. Any ideas?

I"ve attached two pics. The one is of a red mithrax crab which is good and the second is a gorilla crab (has the black tipped pinchers) which is bad.

Black tipped. Might want to google Xanthid crabs. I am under the impression that black tipped crabs are no good.

You sure it is not pink in color and not orange. I have a strawberry crab that looks just like an emerald crab but is pink and has black tip pinchers. They are safe.
