Rhinoceros
The armoured grazer, a prehistoric-looking giant whose horn is keratin, not bone, and whose survival hangs by a thread.
Critically Endangered
Ceratotherium simum
Overview
The white rhinoceros is the largest rhino species and a square-lipped grazer of African grassland. Despite the name, it is grey, 'white' may come from the Afrikaans word 'wyd' meaning wide, referring to its broad mouth. Bulls weigh over two tonnes and mark territory with dung piles and scrapes.
Rhino horns are made of keratin, the same protein as human hair and fingernails, yet demand for traditional medicine drives poaching that has devastated populations. South Africa holds most of the world's remaining white rhinos.

- Open woodland
Open grassland and savanna in South Africa, Namibia, and Kenya suit white rhinos. They need water, short grass for grazing, and intensive anti-poaching protection, most wild populations now live in fenced reserves.

Where to see one
South Africa
In South Africa, strong options include Kruger National Park and Addo Elephant National Park. Classic African savanna, with lions, leopards, elephants, rhinos, and buffalo on self-drive or guided safaris.
Open the South Africa spotting guide for every park note tied to the rhinoceros.
Kenya
In Kenya, start at Lake Nakuru National Park (Rift Valley). Flamingo-fringed lake, rhino sanctuary, and acacia woodland. Compact but spectacular.
More context on this destination lives on the Kenya expedition page.
Diet
White rhinos are grazers with a wide square lip for cropping short grasses. Spend much of the day feeding and resting, returning regularly to water and mud wallows.
Behaviour
Usually found in small groups of females and calves; adult bulls hold territories marked with dung middens. Poor eyesight but keen smell and hearing; can charge when threatened.
How to identify
