Smart and Tasty Mollusk Creates Ethical Dilemma

I didn't finish Sy Montgomery's book The Soul of an Octopus: A Surprising Exploration into the Wonder of Consciousness . . . it was well-written and fascinating, but too much octopus and not enough consciousness; I will think twice before ordering this brainy cephalopod at the Greek restaurant near my house, though they make it just right; these creatures are smart, playful, spirited, and clever . . . and they can recognize people and treat them very differently, depending how comfortable they are and how much they "like" them (the only rationalization for eating them is that they don't live very long-- three years or so-- but I'm not sure if that's a logical reason, because dogs don't live all that long and we don't eat them when they turn nine).
