Octopuses are among the most intelligent animals in the ocean, and much of their cleverness lies in their arms. Each arm contains a large number of nerve cells, allowing it to taste, touch, and react almost on its own. This means an octopus can explore several hiding places at once while the central brain attends to other tasks. Scientists studying this unusual setup hope it may one day inspire new kinds of flexible robots that can grip and feel like a living limb.
