Following the phylogenetic species concept, recent research has suggested the northern white rhinoceros may be an altogether different species, rather than a subspecies of white rhinoceros, in which case the correct scientific name for the former is Ceratotherium cottoni. The two other rhinos presently live at the San Diego Zoo's Safari Park in California. One of two remaining in the Czech Republic died in late May 2011. Four of the six rhinos (which are also the only reproductive animals of this subspecies) were transported to Ol Pejeta Conservancy in Kenya, Africa, where scientists hope they will successfully breed and save this subspecies from extinction. Initially, six northern white rhinoceros lived in the Dvůr Králové Zoo in the Czech Republic. In the world, there are currently only three rhinos of this subspecies left in captivity and four have been returned to a conservancy in Kenya. Formerly found in several countries in East and Central Africa south of the Sahara, this subspecies is a grazer in grasslands and savanna woodlands. Northern white rhinoceros – The northern white rhinoceros, or northern square-lipped rhinoceros (Ceratotherium simum cottoni) is considered Critically Endangered or Extinct in the Wild.However, for reasons that are not currently understood, the rate of reproduction is extremely low among captive-born southern white females. For instance, 91 calves have been born at the San Diego Zoo Safari Park since 1972. 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. Populations have also been introduced outside of the former range of the species to Kenya, Uganda and Zambia. There are smaller reintroduced populations within the historical range of the species in Namibia, Botswana, Zimbabwe and Swaziland, while a small population survives in Mozambique. South Africa is the stronghold for this subspecies (93.0%), conserving 16,255 individuals in the wild in 2007 (IUCN 2008). Southern white rhinoceros – As of 31 December 2007, there were an estimated 17,480 southern white rhino in the wild (IUCN 2008), making them the most abundant subspecies of rhino in the world.There are two subspecies of white rhinos the southern white rhinoceros (Ceratotherium simum simum) and the northern white rhinoceros. The northern subspecies has very few remaining, with seven confirmed individuals left (including those in captivity). The white rhinoceros consists of two subspecies: the southern white rhinoceros, with an estimated 17,460 wild-living animals at the end of 2007 (IUCN 2008), and the much rarer northern white rhinoceros. It has a wide mouth used for grazing and is the most social of all rhino species. The white rhinoceros or square-lipped rhinoceros (Ceratotherium simum) is one of the five species of rhinoceros that exist.
