Emerald Crap missing limbs

[pyro]

Well, a LFS gave me a free emerald crab because it wasn't looking too good. No sign of disease, just physical harm. There is only one leg on his left side instead of the 3 or 4 there are normally and the upper tip (the "cupped" part) of his left cheliped or claw has broken off.
He seems healthy and is picking food off the rocks and has fended off the hermit crabs very well so far. Do you think he will survive? He looks healthy, but I'm not sure if there is anything I can do to help.
Thanks!

As long as he is eating, and is not being attacked, he should do fine. As he molts, he will replace the missing limbs.
Sounds like he is either old, or has been in a scrap or two!
