Do lobsters, crabs, and other crustaceans feel pain? And, if so, would you stop eating them altogether?
New research suggests that, contrary to previous belief, the popular summertime dinners do in fact feel it when we toss them into boiling water. During a Queen's University study by Robert Elwood and Barry Magee, ninety shore crabs were placed into a bright tank with dark shelters on either side (as shore crabs [and most other crustaceans] enjoy dark, shadowy hiding spots). The crabs under one of the dark spots were given a series of small electric shocks, and this was repeated twice. After a second round of shocks, the crabs were returned to the tank and were yet again given the choice between the two shelters. This time, a vast majority of the shocked crabs went to the other dark spot, avoiding the spot where they'd been electrocuted.
However, many argue that this phenomenon is due to nociception, or a reflex reaction to being touched. But Magee and Elwood counter with the fact that the shore crabs felt the unpleasant effects of the shock and could recall where they received it and try to avoid the experience again proves that it was pain that the crabs felt. “I don’t know what goes on in a crab’s mind … but what I can say is the whole behavior goes beyond a straightforward reflex response and it fits all the criteria of pain,” said Elwood.

I don't eat seafood, but I still would not object to the consumption of lobsters and crabs because in my view they are meat just like pigs and cows and chickens. I just could never, ever be the one to drop them into the pot. I think that most people won't be able to give up the favorite summer dinner, no matter how much they know that it hurts the animal. But, next time you're about to cook up some crustacean dinner, maybe you'll think twice about tossing the lobster into the scalding water.
