Crab question

[Original Fin]

Bad guy, right? Claw tips are black, and has hairy legs. Found this sitting on the sand today, either dead or a molting, not sure...would a crab molting look like this?
I rolled it between my finger tips, and it seemed pretty much hollow...no ooze or guts, so I'm thinking the little bugger's still in the tank, only bigger.

im no for sure but it doesnt look like a molt to me. i also believe that that crab is deadly poisonous and can grow to the size of a chicken
j/k.......
it looks like an emerald, i think, but not positive. hopefully someone else will jump in and give their 2 cents

Hmmm...I'm pretty sure it's not an Emerald. Saw one in the LFS yesterday, and this one is a different color. Kind-of light rust colored, and has really hairy legs. Also, has dark red eyes...just looked like a evil sucker.

Another thing that leads me to believe it's a bad guy, is that when I was examining it, it sprayed out some sort of acid, and then flew across the room and attached itself to another crewmembers face, and inserted a long proboscis down his throat. He seems to be ok though.
On another note, I found some interesting pod growths behind the live rock in my tank...I'm gonna go poke around at them in a few minutes...

Emerald crabs do not have red eyes, so it can't be an emerald crab.

It is.

Red-eyed crab hitchhikers are usually Xanthids or members of the family Menippidae. Either way they're bad news.
