Consider the lobster

    The fact that even the most highly evolved nonhuman mammals can’t use language to communicate with us about their subjective mental experience is only the first layer of additional complication in trying to extend our reasoning about pain and morality to animals. And everything gets progressively more abstract and convolved as we move farther and farther out from the higher-type mammals into cattle and swine and dogs and cats and rodents, and then birds and fish, and finally invertebrates like lobsters.
