Octopuses have three hearts, blue blood, and remarkable intelligence. They can solve puzzles, mimic other creatures, and even use tools. Their neurons aren’t centralized in the brain but spread through their arms, giving them decentralized problem-solving skills. Studying octopuses reveals alternative forms of intelligence, challenging human notions of cognition and creativity, and inspiring robotics, AI design, and novel approaches to learning from nature’s most enigmatic engineers.
