Answer

Common waterbuck and the Defassa waterbuck

The text explicitly identifies two major subspecies within the overall waterbuck species, *Kobus ellipsiprymnus*. These are referred to as the Common waterbuck and the Defassa waterbuck. The Defassa waterbuck is specifically noted in discussions pertaining to East African habitats. While their fundamental dietary requirements—grass consumption—remain consistent, differences in the dominant grass species encountered across their distinct geographic ranges can lead to subtle variations in their diet.
