The rhino photos displayed here are all of the white or square-lipped rhinoceros (Ceratotherium simum), which is a lot larger but less agressive
than the black or hook-lipped rhineceros (Diceros bicornis).
The feature that most clearly distinguishes the white rhino from the black rhino is its broad, square lip that it uses for grazing grass, as opposed to browsing leaves and twigs from shrubs or trees.
For anyone visiting Africa on safari, you're much more likely to see white rhinos in the national parks and game reserves of southern Africa than the
black variety which is more scarce and also more shy. All rhinos are, however, under severe threat following a massive increase in rhino poaching to fuel the surging demand
for rhino horn in China and Vietnam.
