Black rhinoceros - online puzzles

The black rhinoceros or hook -lipped rhinoceros (Diceros bicornis) is a species of rhinoceros, native to eastern and southern Africa including Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Swaziland, Tanzania, Zambia, and Zimbabwe. Although the rhinoceros is referred to as black, its colors vary from brown to grey.

The other African rhinoceros is the white rhinoceros (Ceratotherium simum). The word " white " in the name " white rhinoceros " is often said to be a misinterpretation of the Afrikaans word wyd (Dutch wijd) meaning wide, referring to its square upper lip, as opposed to the pointed or hooked lip of the black rhinoceros. These species are now sometimes referred to as the square -lipped (for white ) or hook -lipped (for black ) rhinoceros.The species overall is classified as critically endangered (even though the South-western black rhinoceros is classified as vulnerable). Three subspecies have been declared extinct, including the western black rhinoceros, which was declared extinct by the International Union for Conservation of Nature (IUCN) in 2011.

Taxonomy

The species was first named Rhinoceros bicornis by Carl Linnaeus in the 10th edition of his Systema naturae in 1758. The name means "double-horned rhinoceros ". There is some confusion about what exactly Linnaeus conceived under this name as this species was probably based upon the skull of a single-horned Indian rhinoceros ( Rhinoceros unicornis), with a second horn artificially added by the collector. Such a skull is known to have existed and Linnaeus even mentioned India as origin of this species.
