Help crab identity

[cruzersmith]

I was sold this as an emerald crab to help with bubble algae. It doesn’t look like one to me. It also doesn’t look like a pithos

crab as it is quite flat. This is the best picture I could get in daytime.

can you get any white light photos? this will help greatly
hard to say for certain by these photos but the fuzz on it makes me think it could be a gorilla crab

It is difficult to see, it does seem to look like an emerald but a picture where I can see the front pincers will really help. They are tong like for pulling algae.

Yeah, I think we need clearer pics with no blue light and all the white you have for clarity.

One hallmark of a gorilla crab is 'chocolate dipped claws', so if it's front pinchers seem like they were "dipped in chocolate', you might have the dreaded beast

Looks like a pitho crab to me.

Well unfortunately it has moved and disappeared. I used an orange filter for these shots. I’ll try to get better photos if I can find it again. Thanks for all the replies.

That sounds like a crab

Couldn’t get the white light yet but a little better pictures.

Emerald crab, no doubt!

I guess I expected it to be a little green.

I’ve had many that were almost white and everything in between.

Agreed, that spud is an Emerald (Mithrax) crab

Their shell color can vary a bit when they are molting. There's definitely a ruby red version too, basically the same crab but with a red shell.

Largely considered a good guy to have, but all crabs can crab, from time to time, if you know what I mean
