Name
White or Square-lipped Rhinoceros [Ceratotherium simum]
Appearance
The
White Rhino is the third largest land mammal. Massive, stocky, and with
a reputation of being not quite as aggressive as the Black Rhino. The
two distinctive horns are in fact very densely packed fibers, and
materially not really horns. The record horn length is 1.58 m. Bulls,
weighing up to 2 000 kg, are larger than cows which weigh up to 1 800
kg. Bulls are 1.8 m at the shoulders. The grey skin is almost hairless.
They have a square-shaped, wide mouth. White Rhinos have a hump on the
neck. The penis points backwards and testes are located abdominally.
Diet
The
White Rhino is strictly a grazer. Favouring short grass, but will feed
on taller grass when short grass is not available. The wide mouth
enables adequate intake with each plug harvested with the upper and
lower lips.
Breeding
Even
though most conceptions take place during the wet season, this huge
mammal is not a strict seasonal breeder. Calves are born early in the
dry season after a gestation period of 16 months, and stays with their
mothers for a period of two to three years, until she gives birth to her
next calve. Cows starts breeding at about eight years and bulls reach
sexual maturity at 10-12 years. During mating, sexual activity can last
more than an hour.
Behaviour
In spite of their bulk and
short stubby legs, White Rhino can run remarkably fast, but only for
very short distances. Dominant territorial bulls occupy mutually
exclusive areas of two to five square kilometers, but one or more
subordinate bulls may share the territory. Female ranges may overlap
those of several bull territories. A territorial bull will attempt to
confine a receptive cow to his territory, and will join her for five to
ten days prior to mating.
Where they are found
Formerly
widely distributed throughout the bushveld regions of South Africa. In
the 19th century it was exterminated by hunters, except in
KwaZulu-Natal’s Umfolozi region. Although now thriving where it has been
re-introduced into parts of its former region, it still suffers from
poaching.
Field notes
The Black Rhino is the original
member of the Big five but due to the scarcity of the Black Rhino the
White Rhino now finds itself as one of Africa’s tourist industry elite.
There is very little difference in colour between the Black and the
White Rhino, the name for the White Rhino stemming from the Dutch term
‘wyd’ which refers to the mouth. This name was thought to be white. The
White rhino is somewhat larger than the Black Rhino |
