The Subjective Experience
Because the majority of its mind is distributed, the octopus challenges human concepts of a unified "self". Philosophical perspectives suggest their consciousness may not be a single conductor leading an orchestra, but rather a collaborative jazz band where the central brain improvises alongside its semi-independent arms.

Evolutionary Path
The transition to a complex mind was likely triggered by the loss of the ancestral shell, which created evolutionary pressure to manage a soft, vulnerable, and highly flexible "protean" body. This led to a feedback loop where a more complex body required a larger nervous system, which in turn enabled more sophisticated behaviors.

Sensory Processing:
Every sucker on an arm contains up to 10,000 neurons dedicated to taste, touch, and smell, allowing the octopus to pull in massive amounts of data through movement.
Unique Anatomy:
The octopus possesses three hearts—two for pumping blood through the gills and one for the body—and blue, copper-based blood that functions efficiently in cold, low-oxygen water.

Their intelligence is defined by a decentralized, distributed nervous system where nearly two-thirds of their 500 million neurons are located in their arms rather than a central brain.
Biological Foundations
Decentralized Intelligence: Each arm acts as a semi-independent processor with its own local sensors, capable of performing complex movements like reaching and grasping even if severed.
AN ALIEN INTELLIGENCE
This 6-minute quick look video explores the unique neurobiology and evolutionary history of the octopus, an animal often described as a real-world "intelligent alien". Unlike vertebrates, octopuses represent an independent experiment in the evolution of complex minds, having diverged from the common ancestor shared with humans approximately 600 million years ago.

The Anatomy: Notice the "yellow speckles" in the Schmidt photo. Those are likely iridophores or specialized cells that AI often ignores in favor of just making the whole thing look like "clear plastic."
Glass octopus: fake vs real
The first image below is an image found all over the internet, including Reddit. The second one is the real thing, from the Schmidt Institute.
See the difference:
The Suckers: On the Schmidt photo, the suckers are individual, perfectly formed translucent cups. In the Reddit image, the suckers on that far-right arm look like melting wax or a mangled gear—classic "AI Hallucination."
Same tool, different content.

Must-listen for: Anyone grappling with the ethics of AI, the rights of animals, or the "alien" intelligence living right here on Earth.
