Add Orange to the List

I saw another Mantis Shrimp while wading the flats today. This one was bright orange. You can just see its head inside the hole in the middle of the picture. So I've seen green, white with brown stripes, tan and now orange - all on the same flat. For fear of getting speared or smacked down, I have not tried to pick one up for closer examination, but it would be interesting to see if these are all different species, or if it is just color morphing based on mood or dominance establishment. I'll have to find a way to collect these guys into a transparent container....
