Research Animals

Capuchin Monkey Research and Welfare

Capuchin monkeys are widely used in behavioral research and have historically been used as service animals, raising significant welfare concerns.

Key Facts

Capuchins are highly social and live in troops of 6-20 individuals in the wild
They have been used in behavioral economics studies demonstrating fairness perception
Training capuchin monkeys as service animals involves years of separation from conspecifics
Social isolation causes measurable psychological harm in capuchin monkeys
Their intelligence and social needs make captive welfare particularly challenging

Welfare Considerations

Capuchin monkeys in research and service animal programs experience welfare harms from social isolation, confinement, and inability to express species-typical behaviors. Their demonstrated understanding of fairness and social reciprocity reflects a level of cognitive complexity that strengthens arguments for welfare protection. Research refinement including group housing and complex environments is ethically required.
