Cool pics man. I cannot verify 100% that those are grass shrimp as they look slightly different then the ones I used to catch in the Chesapeake growing up.
The Bay shrimp were the same size, had the exact same translucent body and dark eyes. However I never saw that green underside on any I ever caught.
Did these guys have sharp spines coming off their head?
Grass Shrimp
Anyway I am 99% they are some variety of grass shrimp as the morphology and habitat look identical to the Bay grass shrimp. Probably some kind of sub-species.
