White Rhino Taxonomy/Description
The White rhinoceros is a member of the rhino family, Rhinoceridae
in the Mammalian Order of Perissodactyla. All other living species
of rhino are also members of Rhinoceridae. Other Perissodactyls
include tapirs and horses. The White rhino's scientific name is
Ceratotherium simus, which means "flat-nosed horned beast". Flat
nose is used to describe the White rhino because the white rhino has
squared lips for grazing.

The White rhino is closely related to the Black rhino. Similarities
between the two species are quite obvious. Unlike the two of the
Asian rhino species (Indian and Javan), the White rhino and Black
rhino have two horns. The Sumatran rhino, although it has two horns,
differs due to its coat of shaggy brown hair. The White rhino, like
the Black rhino, lacks front teeth, differing from the three Asian
species, which all have incisors. The Sumatran rhino also retains
its canines. Although called the 'white', this rhino is actually
dark gray, about the same shade as its close relative, the Black
rhino. 'White' was probably derived from the Dutch word 'weid',
meaning 'wide', which described the animal's broad upper lip. One
may distinguish a White rhino from a Black rhino by its lips. Black
rhinos have pointed prehensile upper lips for browsing on tree
branches and shrubbery, while White rhinos have broad, square upper
lips for grazing on savannah grasses.
The White rhino is the largest rhino species, ranging from
4,000-6,000lbs (1,800-2,700kg) and standing 5-6ft tall at the
shoulder. A massive head is supported by an even more enormous neck
ligament, giving this species a very recognizable hump. The white
rhino is the largest land animal after elephants, although the
hippopotamus may weigh more. Males are generally larger than
females.
White Rhino Habitat/Diet
The White rhino's range once extended throughout North Africa south
of the Sahara and throughout Southern Africa. Long grass and short
grass savannahs are preferred by the White rhino. It is primarily a
grazer, and its square lip is a great adaptation for eating savannah
grass.

White Rhino Behavior/Reproduction
Female and adolescent White rhinos are rarely observed alone. Male
White rhinos however, are solitary animals. White rhinos spend large
amounts of time wallowing in dirt and mud, to keep insects from
biting their sensitive skin. No defined breeding season has been
determined. Competition for females is characterized by males
jousting with their enormous horns. The winner breeds with the
desired female. Gestation is 16 months long. Calves are precocial at
birth, walking shortly after. After two years they leave their
mother, beginning a solitary lifestyle. Females reach sexual
maturity at 6-7 years of age, with males sexually maturing at 10
years. It is estimated that White rhinos live to about 50 years.

White Rhino Conservation
Two populations of White rhino exist. The Northern White rhino
inhabits Central Africa, south of the Sahara. The Southern White
lives primarily in South Africa and its neighboring nations. These
two populations presently total 11,500 individuals. There are more
White rhinos than all other rhino species combined. Unfortunately,
the vast majority of White rhinos living are Southern White rhinos.
Less than 35 Northern White rhinos are still alive. Due to political
instability and poaching, the Northern White rhinos in Garamba
National Park in the Democratic Republic of Congo are in danger of
extinction. But hope is not completely lost. Captive breeding
programs in Dvur Kralove in the Czech Republic and the United
State's own San Diego Wild Animal Park are slowly increasing the
population. In fact, a calf was recently born in Dvur Kralove. The
story of the Southern White rhino provides a glimmer of hope into
the current situation. Once numbering less than 200 individuals at
the start of the 20th century due to poaching, hunting, and
competition for land with farmers, the Southern White rhino suffered
a fate similar to the American bison. But with devoted
environmentalists and conservationists in South Africa, the Southern
White rhino has bounced back, becoming the most abundant rhino
subspecies.
