Whoa, that's a big shrimp! This may not help as I believe it's focused more on grading shrimp by color, but the educational Shrimp Posters at http://buypetshrimp.com/miscellaneous/shrimp-posters/ are very interesting. They could possibly give you ideas for follow-up research.
I suspect it is just a big red cherry shrimp. They do get that size if they live long enough.
