From baboons to howlers, the 300-plus species of monkeys come in many shapes and sizes. And no matter how social they seem, even monkeys born or bred in captivity are wild. They suffer, and pose a threat to humans, when confined in research labs, sold as pets or used in entertainment. Join The HSUS in our work to prevent the wild capture of monkeys and our fight to end inhumane conditions at laboratories.
