Two olive baboons (Papio anubis) engaged in social grooming, an activity that social animals (including humans) engage in to clean or maintain one another's body or appearance. Grooming also reinforces social structures, family links, and builds relationships. It has been best studied among primates, but insects, birds, fish, and other mammals are known to engage in it as well.Photo: Muhammad Mahdi Karim
