Reddit mentions of Other Minds: The Octopus, the Sea, and the Deep Origins of Consciousness

You would like the book Other Minds. It's about Cephalopod psychology and the beginning of the book depicts their evolution.

Edit: Link for the lazy

If you're curious to find out why they live such short lifespans and learn more about their intelligence, I highly recommend "Other Minds" by Peter Godfrey-Smith: https://www.amazon.com/Other-Minds-Octopus-Origins-Consciousness/dp/0374227764 The subtitle is "The Octopus, the Sea, and the Deep Origins of Consciousness." Very readable and informative.

Octopus minds are basically as close as we'll get to encountering alien intelligence.

Wow! Great info! I read this book called “Other Minds”
(https://www.amazon.com/Other-Minds-Octopus-Origins-Consciousness/dp/0374227764) and it suggested that octopuses and cuttlefish use their color as a form of expression, sort of like talking. But in a language specific to the individual. This was based on the non localization of the octopuses “brain” and the lack of continuity in their patterns. Aside from the more primitive communication. This is better described in the book, obviously. Just wanted to pitch in on some already fantastic information, and see if you have any more information to add.
