No shit, Sherlock. Some science wannabes on this planet wants to humanely kill the crabs. Why not adapt them for pets instead of eating them? Why eat fishes, and in those particular countries, whales? Are we going to tell enemy soldiers "now, it's gonna hurt" before shooting them in hope they won't shoot first? No freaking common sense. If you think you are gonna piss of few dozen crabs by boiling them alive, don't eat 'em! I like 'em with Old Bay seasoning.
