Cetacean intelligence research has revealed cognitive abilities - tool use, complex communication, cultural transmission, and self-awareness - that have profound implications for how we assess their welfare needs and moral status.
Cetacean intelligence welfare implications are substantial: animals capable of cultural transmission, long-term social memory, and self-awareness likely have correspondingly rich subjective experiences. Welfare harms - captivity, acoustic disturbance, entanglement - are experienced by beings with the cognitive complexity to remember them, anticipate them, and be affected by their cumulative impact. This cognitive profile underpins arguments for legal personhood for cetaceans, proposed in multiple jurisdictions. More immediately, it strengthens the case for robust welfare protections in fishing regulations, noise pollution standards, and captivity bans.
