Huge hermit question

[SoFloReefer]

I saw a huge hermit crab in the intercoastal today. It was in a 8" long conch shell and had two huge claws with blue dots all over them. Looking on google images I found a picture that looks the same as what I saw. http://www.google.com/imgres?imgurl...x=175&ty=67&page=1&ndsp=24&ved=1t:429,r:1,s:0
Does anyone know what kind of hermit crab this is?
