White Rhino (Ceratotherum simum)

The white rhino, along with the roughly equal-sized Greater one-horned (Indian) rhino, is the largest species of land mammal after the elephant. The white rhino is the least endangered of the living rhino species. Of its two distinct subspecies, the only populations of the Southern white rhino populations remain viable. The Northern white rhino has been driven to near-extinction by poaching.
