Diceros

Diceros is a genus of rhinoceros in the family Rhinocerotidae, native to Africa. It contains the African black rhinoceros, Diceros bicornis, the sole living species currently assigned to the genus. The genus is distinguished from Ceratotherium (the white rhinoceros) by differences in dentition and horn morphology, and by its browsing lifestyle.

Historically widespread across sub-Saharan Africa, black rhinos today live mainly in protected savannas, woodlands, and scrublands in eastern and southern Africa, with smaller populations in some western African reserves.

The black rhinoceros is smaller and more slender than the white rhinoceros, with a prehensile upper lip used to grasp foliage. It has two horns on the snout, the front horn usually larger. Its skin is thick and folded, giving a rugged appearance. It is primarily a browser, feeding on shrubs and trees, and is typically solitary or seen in mother–calf pairs; males defend territories.

Reproduction and life history: Females reach sexual maturity around five years; gestation lasts about 15 to 16 months, and calves stay with their mothers for two to three years.

Conservation: The species is threatened by poaching for horn and habitat loss. It is the focus of intensive conservation programs, anti-poaching patrols, and habitat protection in many countries. Several subspecies have varying ranges and statuses, but the genus Diceros is represented by the black rhinoceros today.
