And now for a little old school technology. This little antelope is called a dik dik (I know, strange name) and figured I’d try an animated gif file to show how it constantly is moving its nose around. The flexible, trunk-like snout serves as a radiator to cool blood which flows through the nasal passages to the brain. This allows the dik-dik to be independent of surface water and to get its moisture from a leafy diet. Although you can’t really tell from this photo, dik diks are extremely small, one of the smallest antelopes on the planet, and when you see them running, they almost look like large rabbits.
