Octopuses are among the most cognitively complex invertebrates, and evidence for their capacity to suffer is growing.
The welfare case for octopuses is among the strongest for any invertebrate. Their neural complexity, evidence of nociception, and demonstrated motivational responses to harm all suggest genuine suffering capacity. Yet octopuses are fished in vast quantities with no welfare consideration, boiled alive in cooking, and increasingly considered for farming with minimal welfare framework. The evidence base for octopus sentience is strong enough to justify the same precautionary welfare approach applied to vertebrates. The gap between what science shows and how octopuses are treated is one of the largest in current animal welfare practice.
