Octopuses, squid, and cuttlefish are increasingly recognized as sentient, raising welfare concerns in research and farming.
Cephalopods are extraordinarily intelligent invertebrates whose sentience is now recognized in law by multiple jurisdictions. Octopuses are solitary hunters who in captivity require enrichment and adequate space to avoid chronic stress. Commercial octopus farming raises serious welfare questions — the animals are protein-expensive to farm, solitary by nature, and require complex environments. Extending welfare consideration to cephalopods reflects growing scientific consensus about the breadth of animal sentience.
