After a lot of research I had concluded the following as the biggest difference between Sri Lankan monkeys and African Monkeys (or is it Baboon?). Interestingly local ones (as long as I had seen) carry their little ones below the belly, where as the African ones seems to carry them on their backs!
African ones - I called this picture the "parents meeting"
Our ones - This one is called as "lil one"
But irrespective of the continent or species the mothers love doesn't change!
