Human feeding of wild dolphins habituates them to boats and people, causing behavioral changes that increase injury risk and reduce natural foraging behavior with significant welfare consequences.
Feeding wild dolphins feels like an act of connection and care but causes measurable welfare harm through behavioral modification. Dolphins that associate humans with food spend less time in natural foraging, become vulnerable to boat strikes from seeking human contact, and teach their calves maladaptive behaviors. Long-term studies at provisioned sites show higher calf mortality and altered social dynamics in provisioned females. The harm is invisible at the moment of interaction but accumulates across animal lifetimes and generations. Not feeding wild dolphins is one of the most direct welfare interventions available to recreational ocean visitors.
