Octopuses and squid have large, complex nervous systems and show learning and problem solving.
Octopuses have about 500 million neurons, two-thirds in arms, can solve puzzles, use tools (coconut shells) and learn by observation. Chromatophores allow rapid camouflage. Short lifespans limit learning transfer.
Octopuses learn by observation and show play. Their nervous system is distributed. Short lives limit knowledge sharing.
Remember: they have blue blood with haemocyanin.
