As you already know the picture is blurry and taken from an unfortunate angle. If you can get a better picture (full side view with rostrum and claws visible) then we can start giving you educated opinions. One thing I can tell you is that it does not look like Palaemonetes paludosus.
Hmmm...there are a number of Macrobrachium species that look exactly like that. It's *for sure* not Palaemonetes paludosus, could possibly be Macrobrachium lanchesteri. I'm fairly certain it's a Macrobrachium species, though. If you could get a full side view I could confirm or refute that it's actually M. lanchesteri.
