Octopuses challenge much of what we assume about intelligence. Unlike mammals, they concentrate most of their neurons not in a central brain but in their arms, each of which can taste, touch, and react with a degree of independence. In aquariums, octopuses have unscrewed jars, recognised individual keepers, and squeezed through gaps barely wider than their beak, the only hard part of their body. Yet this brilliance comes with a strange cost: most species live only a year or two and die shortly after reproducing, leaving no chance to pass knowledge to their young. Whatever an octopus learns, it learns alone, which makes their problem-solving all the more remarkable.
