Cuttlefish are among the most cognitively sophisticated invertebrates. As aquaculture interest grows, their capacity for sentience demands serious welfare consideration.
The cognitive sophistication of cuttlefish presents a compelling case for treating them as sentient beings warranting welfare protection. Their ability to plan, remember, and make complex decisions suggests a rich inner life that goes beyond simple reflexive behavior. Yet they remain almost entirely unprotected by animal welfare legislation — the EU includes cephalopods in some research regulations but commercial fishing and emerging aquaculture remain largely unregulated from a welfare perspective. The welfare implications of common capture methods — netting, traps — and potential mass farming deserve urgent attention from policymakers and researchers. The precautionary principle argues strongly for extending welfare protections to this group.
