Mantis shrimp in Cozumel??

Just returned from Cozumel - two great weeks had by all. I was very surprised to see this mantis shrimp on a beach dive off Corona Beach ( actually spotted by my son who nearly had his index finger split in half! ) I thought these guys belong in the Pacific. Anyone seen them in Coz before?. I have a few other pics if required

There are mantis shrimp all over the caribbean. Nothing unusual. This guy is Dark Mantis Shrimp (Gonodactylus curacaoensis).

Your photo is better than mine, but here is a photo of that same species I took in Key Largo.

{who ever reported this, would you please PM or email me with what Norton said about my site?}

I, too, have seen them in the Caribbean but only the "white" variety. That guy has great color....
