 will release and then you're left with less of a shrimp i mean they'll shrink they'll shrink up a little bit anyways but um not as much so you can buy if you buy whole shrimp they don't pump them you know i mean but then you have the heads to deal with in the shells and then you know if your shrimp is two and a half inches long you end up with three quarters of an inch tail this little thing you know i mean um but that's some of the best shrimp that you can buy
