Black Rhinocerosクロサイ
Diceros bicornisCR— Critically Endangered
The black rhinoceros is a browsing rhino of East and Southern Africa, distinguished from the white rhino by its pointed, prehensile upper lip used to strip leaves from shrubs and trees. Relentless poaching for its horn drove a catastrophic 96% population decline between 1970 and 1992, and one subspecies, the western black rhinoceros, was declared extinct in 2011. With roughly 3,142 mature individuals remaining, the species is classified as Critically Endangered by the IUCN.
