My favorite animal chronicler, Sy Montgomery, has written a great article on the octopus and the bewildering nature of octopus intelligence.
Read the article and imagine yourself in the distant future, aboard a galactic ship crewed by beings from across the universe. You’ve got a new roomie, one from your home planet. Oh, boy! Another human, after years of being the only one onboard! Nope. It’s an octopus. She eyes you from the comfort of a brown beer bottle as you nervously search for a copy of the Octopus Enrichment Handbook in the All-Earthican Digital Library.
