Decades of research has documented extraordinary cognitive abilities in dolphins including self-recognition, tool use, cultural learning, and emotional complexity, with profound implications for their welfare treatment.
Dolphin intelligence research has fundamentally transformed understanding of what dolphin welfare requires. Self-awareness, tool use, cultural transmission, and complex social bonds are not peripheral features — they are central to dolphin cognition. This means that disrupting social bonds, preventing cultural transmission, and confining animals in cognitively impoverished environments causes a qualitatively different kind of harm than deprivation for less cognitively complex animals. Drive hunting that kills entire pods destroys social networks built over decades. Captivity prevents the use of intelligence in any meaningful way. The welfare case for dolphins is among the strongest for any non-human animal.
