I’m not sure you’ll believe me, but you can smell the difference between a blue crab and any other breed of crab, I could tell a sally from a sook on touch alone, and even when they molt, the oil won’t come off. I knew this, apart from the smells, before I knew the lab. I could’ve told you that we’d turn to blue crabs if this ever happened. They’re small enough to be prey but with enough fight to eat some, too, and in the middle, that’s where you tell how things are shaping up. So, the blue crab.
