Help ID, Crab?

[MaxwellSilver]

I just found this crab(?) today, 8 legs and I cant see any pincher, sorry the photo is not clear but he is blending with the rock as well. There seems to be a molt right beside him unless it is a lighter color of same species.

I can't decifer between the rock and crap from the picture

Sorry my lights aren't ON yet and I'm not sure if he'll show up later but I'll try to take a better picture when I come home and if he still there. I'm not sure if its a crab because I can't find his pinchers but there are 8 legs. He is the one on the right circle and the other one is what I think is a molt.

Ok, I think i got a better pic. It looks like it has a skull in it's back. Is it a good crab?

[Aquaria]

Skulls equal bad right?

Looks like it might be a decorator type? Similar body to the one I used to have.

And they don't have large pinchers.
