The Black Rhinoceros (Diceros bicornis)
is also called the Hook-Lipped Rhinoceros. It lives in eastern and southern
Africa and it is critically endangered.
It is not
actually black: it is grey or dark grey.
It has two horn-like keratin growths, one behind the other. The front
horn is larger than the second horn. The front horn is about 50-140 centimetres
(2 to 4.5 feet) long, which is longer than the horn of White Rhinoceroses. Sometimes, a third,
smaller horn may develop.
They can grow to about 1.8 metres (6 feet), which is about half the
size of a White Rhinoceros.
It has a pointed and
prehensile upper lip, which it uses to grasp leaves and twigs from trees when
feeding. Therefore it is a herbivorous browser. White Rhinos are grazers
because they eat grass. Because the Black Rhino eats from trees, it prefers
habitats with thick scrub and bushland.
Black Rhinoceros can
also distinguished from the White Rhinoceros by its size, smaller skull,
smaller ears, and by the position of the head, which is held higher than the
White Rhinoceros. Black Rhinos have longer horns and are hook lipped (for
browsing) instead of square lipped (for grazing).
They are
very fast and can reach speeds of 55 kilometres per hour (34 miles per
hour) running on their toes.
