An extreme contrast in the proportional size of the jaws in large herbivores of grassland: ostrich vs warthogs

One of the remarkable aspects of the guild of large herbivores in Africa is the extreme variation in the proportional size of jaws, among species specialised for eating herbaceous plants.

The extremes are shown by the ostrich (Struthio camelus, and warthogs (Phacochoerus spp.,

Warthogs are the most specialised of suids, on a diet of grass (,stems%2C%20roots%2C%20and%20seeds. and and and and

For its part, the ostrich is an 'honorary ungulate' in the sense that it, like coexisting gazelles, eats mainly greens ( and and and and,on%20these%20types%20of%20nutrients. and and

The notion that the ostrich is omnivorous is one of those ambivalences that has misled generations of naturalists. While it is true that the ostrich has the capacity to eat animals and various other categories of food, its staple diet, wherever it lives in the wild, is foliage.

Warthogs, too, retain a capacity for eating animal matter that exceeds that of most ruminants. Therefore, it turns out that the ostrich is directly comparable with coexisting warthogs in an ecological sense - the great phylogenetic distance between them notwithstanding.
