The Oryx (Oryx sp) is an antelope, which is a hoofed ruminant mammal.
Ruminants have well-developed molar teeth, which grind plant-based food – called the cud – into food balls.
The Oryx, like all antelopes, has no upper incisors. Instead, it has a hard, upper gum pad. The lower incisors use the gum pad to bite and tear grass stems and leaves.
Ruminating animals – ruminants – have continuously growing teeth throughout their life.
Humans have teeth that stop growing after a person is a certain age.
