Black rhinoceros
The black rhinoceros is an African rhinoceros with a hooked upper lip adapted for grasping leaves and twigs. It is critically endangered.
Rhinoceros: A large, thick-skinned herbivorous mammal in the family Rhinocerotidae, characterized by one or two horns. The black rhinoceros is one of five living rhinoceros species.
Black rhinoceros conservation: The protection and recovery work directed at black rhinoceros populations and their habitats. Conservation programs combine anti-poaching measures, monitoring, and population management.
White rhinoceros: An African rhinoceros with a broad, square upper lip adapted for grazing grasses. Its grass-grazing muzzle contrasts with the black rhinoceros's hooked browsing lip.
Southwestern black rhinoceros: The black rhinoceros subspecies Diceros bicornis bicornis, native to southwestern Africa. This subspecies persists mainly in Namibia and South Africa.
Rhinoceros horn trade: The domestic and international commerce in rhinoceros horn, both legal and illegal. Reducing demand and disrupting illegal trade remain central conservation challenges.
Rhinocerotidae: The mammal family containing living and extinct rhinoceroses. This family places the black rhinoceros among its closest living relatives.
Rhinoceros poaching: The illegal killing of rhinoceroses, chiefly to obtain and sell their horns. Demand for horn has driven severe losses across the species' range.
Javan rhinoceros: A critically endangered Asian rhinoceros, now surviving naturally only in Java, Indonesia. It is another critically endangered species, but belongs to a different continent and genus.
Eastern black rhinoceros: The black rhinoceros subspecies Diceros bicornis michaeli, native to eastern Africa. Its populations are concentrated in eastern African conservation landscapes.
Habitat fragmentation: The division of continuous habitat into smaller, isolated patches. Fragmented ranges can isolate populations and constrain their long-term recovery.
