What is the maximal age a Black rhinoceros reaches?
An adult Black rhinoceros (Diceros bicornis) usually gets as old as 47 years.
Black rhinoceross are around 466 days in the womb of their mother. When born, they weight 35 kg (77.16 lbs) and measure 91.1 cm (3′ 0″). As a member of the Rhinocerotidae family (genus: Diceros), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 2.85 meter (9′ 5″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
The black rhinoceros or hook-lipped rhinoceros (Diceros bicornis) is a species of rhinoceros, native to eastern and southern Africa including Angola, Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Eswatini, Tanzania, Zambia, and Zimbabwe. Although the rhinoceros is referred to as black, its colours 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 near threatened). 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.
