The rundihorn is the rhinoceros/arsinothere-like gigantelope. It has adopted a body size and a horn arrangement not unlike its predecessor's and is a grazing animal, a fact that is reflected by its broad snout and muzzle. Its alarming horn array is used for defense, although the animal has few enemies likely to risk a frontal attack. For the males, however, its secondary function - for sexual display - is now more important.
