Undecorated Decorator Crab??

Hi All,

My son Jeff was playing with the light on this 1:1 macro shot of a crab in Fiji. He was told it was a decorator crab. I have my doubts but we would appreciate any help.

Thanks, Steve

It looks like an Achaeus which are indeed decorator crabs. The orang crab is in a related genus Oncinopus although in many guide books it's incorrectly listed as Achaeus japonicus.

Thanks Leslie! It was a very small one and we weren't sure.
