Growing scientific consensus that octopuses are sentient beings capable of suffering has sparked urgent debate about their welfare in research and aquaculture settings.
Octopuses are solitary, territory-holding predators with complex cognitive and sensory lives. In captivity, confinement, isolation from appropriate environments, and lack of cognitive stimulation cause measurable stress. Their welfare needs are poorly understood compared to vertebrates, and the development of commercial farming raises concerns about mass housing of individuals with high enrichment requirements and apparent capacity for suffering.
