I have a red-legged hermit crab. I don’t know if it’s a scarlet or something else. All the photos I found on web none have the one oversized claw. Any help will be appreciated.
Could we get some more pictures, so we can see more of the disparity between claw sizes? I found something on Calcinus californiensis, but I'm hesitant to ID it as that until I can get a better look at the crab.
