The Black Rhinoceros
(Diceros bicornis; also colloquially, Black Rhino)
is a mammal in the order Perissodactyla, native
to the eastern and central areas of Africa including
Kenya, Tanzania, Cameroon, South Africa, Namibia
and Zimbabwe. Like all species of rhinoceros,
it is on the endangered species list due to excessive
poaching for their horns, which are mostly used
in dagger handles as a symbol of wealth in many
countries, and as a febrifuge in Chinese traditional
medicine. Contrary to popular opinion, only small
amounts of the horns are consumed as an aphrodisiac.
An adult Black Rhinoceros stands 1.4 to 1.7m high
at the shoulder and is anywhere from 3 to 3.65
m in length. An adult weighs from 800 to 1400
kg, with the females being smaller than the males.
Two horns on the skull are made of keratin with
the larger front horn typically 50 cm long, exceptionally
up to 140 cm. Occasionally, a third smaller horn
may develop. Skin colour depends more on local
soil conditions and their wallowing behaviour
than anything else, so many black rhinos are typically
not truly black in colour.
The Black Rhinoceros
is slightly smaller than the White Rhinoceros,
and has a pointed, prehensile upper lip, which
they use to grasp leaves and twigs when feeding.
White Rhinoceros have square lips used for grazing
grass. The Black Rhinoceros can also be recognized
from the White Rhinoceros by its smaller skull
and ears and its more pronounced forehead. Black
Rhinoceros also do not have a distinguishing shoulder
hump like the White Rhinoceros.
The adults are solitary
in nature, coming together only for mating. Mating
does not have a seasonal pattern but births tend
to be towards the end of the rainy season in drier
environments. The gestation period is 15 to 16
months; the single calf weighs about 35 to 50
kg at birth, and can follow its mother around
after just three days. The mother and calf stay
together for 2 to 3 years until the next calf
is born; female calves may stay longer, forming
small groups. The young are occasionally taken
by hyenas and lions. Sexual maturity is reached
from 5 years old for females, from 7 years for
males, and the life expectancy in natural conditions
(without poaching pressure) is from 35 to 50 years.
