Two-horned rhinoceros

The two-horned rhinoceros (Diceros bicornis), sometimes also called the black rhinoceros, is, together with the pygmy rhinoceros, the representative rhinoceros in Africa. It is a herbivore, and populations of two-horned rhinoceros are found mainly in African reserves. Its range formerly extended across sub-Saharan Africa. Today it is distributed in a few areas of Kenya, Tanzania, Namibia, Zambia and southern Africa.

Of the two species of African rhinoceros, it is the smaller. The body is thick and the skin is grey in colour, almost bare, with no major skin folds. It has hair only on the tips of its ears and tail. The head is short and grows two horns, which are made of keratin (horn) - the stuff from which human nails and hair grow. The head is worn below the level of the back. It doesn't have an occipital bump like the rhinoceros. The legs are short and strong. Another visible difference between the two species is the upper lip, which the two-horned rhinoceros has extended to a point so it can pluck leaves and twigs from trees and shrubs.

The two-horned rhinoceros is a solitary animal. It's intolerant and unpredictable, attacking anything that looks suspicious. Sometimes it's tourists' cars, sometimes other animals. But the violent attacks are usually a bluff, because he has poor eyesight and is short-sighted. In contrast, he has a good sense of hearing and smell, and once he's convinced there's no danger, he calms down. He grazes mainly in the dark and at night. During the day, he prefers to lie in the mud or rest in the shade. The mother leads the cub behind her.

They breed all year round. In Kenya, they peak in September-November. In South Africa, the peaks occur in April-July. Females give birth in periods of 2-5 years. The calf is about 40 kg at birth and is able to take solid food for several weeks. It is weaned at 2 years and is independent at around 2.5-3.5 years.

The two-horned or black rhinoceros is listed on the IUCN Red List under the category: critically endangered - CRITICALLY ENDANGERED (CR/A2abc). Black rhinos were formerly widespread and abundant across sub-Saharan Africa. They are still hunted today for their horns, which are used to make decorative daggers and are used in some Asian countries in traditional medicine, where it is mistakenly imagined that this will lead to increased sexual potency. It is estimated that 90% of adult rhinos are killed by poachers for their horns.
