The Did-dik is a tiny antelope, maybe 12" at the shoulder. It is uniquely built for life in the African savannah. It has a nose that functions like a bellows, cooling the blood as it circulates. It has huge eyes and excellent vision to spot approaching predators. It even has a special gland just below its eye that secretes a sticky substance used to scent-mark territory.
I think this one is Kirk's Dik-dik (Madoqua kirkii). He found us in the central Serengeti (Tanzania).
