How Octopuses Became the Ocean’s Smartest Invertebrates — 25 Problem-Solving Abilities

24. Coordinating Arm Movements Independently

Octopuses possess a unique neural adaptation: their arms can act semi-independently, solving problems without constant direction from the central brain. Research featured in Cell Reports reveals that each arm’s neural network enables it to coordinate movements, explore objects, and react to stimuli autonomously.
This distributed intelligence allows octopuses to multitask, manipulate tools, and interact with their environment in ways unmatched by other invertebrates, further elevating their status as master problem-solvers.
