There are 18 species of woody plants known to the diet of the black rhinoceros, and 11 species that could possibly be a part of their diet too. [51] Black rhinos also have a tendency to choose food based on quality over quantity, where researchers find more populations in areas where the food has better quality. [52] Black rhinos show a ...

The south-central black rhinoceros (Diceros bicornis minor), also known as the south-central hook-lipped rhinoceros or the lesser black rhino, is a subspecies of the black rhinoceros. In keeping with the rules of zoological nomenclature, the south-central black rhinoceros should be known as Diceros bicornis keitloa (Smith, 1836), a nomen novum. [3]
Eastern black rhinos in general are currently listed as threatened under the Conservation Status for a number of factors, but mainly due to illegal poaching. The 90% decline in their population is a hazard as mortality rates increase, as is consistent emigration (Primack, 2002).
Three subspecies of the black rhinoceros, the Syrian wild ass subspecies of the onager, and the tarpan subspecies of the wild horse have gone extinct in the last 200 years. The eighteen extant species of Perissodactyla are divided into two suborders: Ceratomorpha, containing the families Rhinocerotidae and Tapiridae , and Hippomorpha ...
Dynastinae or rhinoceros beetles are a subfamily of the scarab beetle family (Scarabaeidae). Other common names – some for particular groups of rhinoceros beetles – include Hercules beetles, unicorn beetles or horn beetles. Over 1,500 species and 225 genera of rhinoceros beetles are known. [2]
Four species are considered critically endangered: the Javan rhinoceros, the Sumatran rhinoceros, the black rhinoceros and the African wild ass. Six species are endangered : the mountain tapir , the Central American tapir , the Malayan tapir , the wild horse and Grévy's zebra .
The western black rhino emerged about seven to eight million years ago. It was a sub-species of the black rhino. For much of the 20th century, its population was the highest out of all of the rhino species, at almost 850,000 individuals. There was a 96% population decline in black rhinos, including the western black rhino, between 1970 and 1992.
