White Rhino

Description

The White Rhinoceros or Square-lipped rhinoceros (Ceratotherium simum) is one of the five species of rhinoceros that still exist and is one of the few megafauna species left. Behind the elephants, it is probably the most massive remaining land animal in the world, along with the Indian Rhinoceros and the Hippopotamus, which are of comparable size. It is well known for its wide mouth used for grazing and for being the most social of all rhino species. The White Rhino is the most common of all rhinos and consists of two subspecies, with the northern subspecies being rarer than the southern. The northern subspecies may have as few as 13 remaining world wide.

Taxonomy and naming

A popular theory of the origins of the name White Rhinoceros is a mistranslation from Dutch into Afrikaans and English. The Afrikaans word "wit", meaning "white" in English is said to have been derived by mistranslation of the the Dutch word "wijd", which means "wide" in English and is spelt "wyd" in Afrikaans. The word "wide" refers to the width of the Rhinoceros mouth. So early European settlers in South Africa misinterpreted the "wyd" for "white" and the rhino with the wide mouth ended up being called the White Rhino and the other one, with the narrow pointed mouth, was called the Black Rhinoceros. A review of Dutch and Afrikaans literature about the rhinoceros has also failed to produce any evidence that the word wyd was ever used to describe the rhino. Other popular theories suggest the name comes from its wide appearance throughout Africa, its colour due to wallowing in calcerous soil or bird droppings or because of the lighter colour of its horn. An alternative common name for the white rhinoceros, more accurate but rarely used, is the square-lipped rhinoceros. The White Rhinoceros' generic name, Ceratotherium, given by the zoologist John Edward Gray in 1868, is derived from the Greek terms keras "horn" and therion "beast". Simum, is derived from the Greek term simus, meaning "flat nosed".

Southern white rhinoceros

There are two subspecies of White Rhinos; as of 2005, South Africa has the most of the first subspecies, The Southern White Rhino (Ceratotherium simum simum). Their population is about 11,600, making them the most abundant subspecies of rhino in the world. Wild-caught southern whites will readily breed in captivity given appropriate amounts of space and food, as well as the presence of other female rhinos of breeding age. For instance, 91 calves have been born at the San Diego Wild Animal Park since 1972. However, for reasons that are not currently understood, the rate of reproduction is extremely low among captive-born southern white females.

There were also two White Rhinos in Livingstone, Zambia (in the Mosi-o-tunia zoological park). They were both poached during the night of June 6, 2007. One was shot dead and dehorned not far from the gate and the other received serious bullet wounds.
