What feeding structure allows the white rhino to function as a pure grazer?

Answer

Broad, square lip

The white rhinoceros is specialized as a pure grazer, meaning its diet almost exclusively consists of grass found close to the ground. This feeding strategy is supported by a unique anatomical feature: a broad, square lip. This structure functions efficiently much like a lawnmower blade, allowing the animal to clip short grasses very close to the soil surface. This highly specific adaptation contrasts significantly with the feeding habits of browsing rhinos and makes the white rhino less adaptable if grass sources become scarce in their environment.
