Looks like a marine shrimp, but collected in full freshwater. A freshwater creek flowing into Indian river lagoon.
Collected in cast net off dock on Whitaker bayou.
Found this guy on his last breaths after TS Sally went through. Tail appeared injured. I lifted him back into the water and he swam off.
Caught using a bobber, 8/0 brass live bait hook, and a baby night crawler.
