Endemic mammals are the Silver Dik-dik (Madoqua piacentinii), one of the world's smallest antelopes, and the Somali golden mole (Calcochloris tytonis).
If a savannah had a utility function, cheetahs would have had no need to waste energy running as fast as a Lamborghini and antelopes would have found it unnecessary to waste resources trying to escape a gruesome death.
Deer, antelopes, ducks, pheasants, thrashers and quails can be found in the upland areas amongst the sagebrush, greasewood and wild rye.
