Debate Continues: Did Your Seafood Feel Pain?: The scientific debate on the subject has intensified recently, with a team of British researchers proposing this month that electroshock tests suggest crabs indeed feel pain. But the study has drawn scrutiny, while another study late last year pushed back on the idea that fish, more closely related to humans than are crabs, feel pain.
In the beginning of things men were animals and animals men. ~ Algonquin saying
"For instance, on the planet Earth, man had always assumed that he was more intelligent than dolphins because he had achieved so much — the wheel, New York, wars and so on — whilst all the dolphins had ever done was muck about in the water having a good time. But conversely, the dolphins had always believed that they were far more intelligent than man — for precisely the same reasons." ~ The Hitchiker's Guide to the Galaxy
