What it’s like to be an octopus? This review of Peter Godfrey Smith’s book, Other Minds: The Octopus, the Sea, and the Deep Origins of Consciousness, captures perfectly why I’ve been fascinated by them — they’re the closest thing to aliens we’ve got.
Unlike cetaceans – whose sentience it is possible to imagine, partly because they demonstrate our mammalian connections so vividly and physically – cephalopods are entirely unlike us. “If we can make contact with cephalopods as sentient beings, it is not because of a shared history, not because of kinship, but because evolution built minds twice over,” says Godfrey-Smith. “This is probably the closest we will come to meeting an intelligent alien.” The fact that they have eight legs, three hearts, and blue-green blood allies them more with The Simpsons’ gloopy extra-terrestrials than anything earthly.
