Different,but connected by a community!

Two different species of same community 'Primates' - Rhesus macaque grooming a Common langur.Social grooming is an activity in which individuals in a group clean or maintains one another's body or appearance. It is a major social activity, and a means by which animals that live in proximity may bond and reinforce social structures, family links, and build relationships.It is usually seen in a same group of species. This is something different I observed.
