The Southern White Rhinoceros (Ceratotherium simum simum) is a subspecies of the White Rhinoceros and is the most common subspecies of rhino in the world. It is assesed as near threatned by the IUCN red list. Almost all of these creatures live in South Africa. The conservation status of a species is an indicator of the likelihood of that species continuing to survive. ...

Description
The Southern White Rhinoceros is larger than the northern subspecies. Adult males can weigh up to 2.5 tonnes and females 1.9 tonnes. Usaully 59 inches tall at the shoulder. Color is light which can range from yellow-brown to grey. It has stubby legs and has a very large hump on its back. They have two horns, the front one being the largest and can be as long as 36 inches. The horn grows through out its entire lifetime. It also has a broad flat mouth for grazing. Like all rhinos it has has a poor eyesight but a very good sense of smell.
Habitat & Beahavior They inhabit grasslands and savanah woodlands. Like the Northern White Rhinoceros it is also a grazer. The wide lips allow it too get as much food intake as possible. It is actually one of the largest pure grazers in the world. The rhinos have home territorys and the adult bulls are solitary while the female and calves form family groups. Not very aggresive but instead very sociable animals. Most active in the evening they spend the daytime hours wallowing in mudbaths or resting. It has no predators except for man.
Reproduction Cows reach sexual maturity at 6-7 years of age while the bulls reach sexual maturity at 10-12 years of age. The females will usaully breed with the dominant male of the territory. Fights between males for cows are common and can get quite serious. Mating may last as long as two hours. Breeding pairs may stay together for as long as 20 days. Gestation occurs over 16 monthes and when born they weigh around 143 pounds. The calves are weaned after 1 year and the birth interval for this subspecies is 4 years.
Population At the beginning of the 1900's only a small population of 20 animals remained after decimation from the killings by hunters and farmers. This made them the rarest subspecies of any rhino at this time. But because of great conservation measures their population has boosted to the most common of rhino subspecies. Now their are over 11,600 wild southern white rhinos and 767 indiviuals in zoos. They have more numbers of this subspecies of White rhino than all the other subspecies of rhino combined. Very easy to breed in captivity although for reasons unknown, the rate of reproduction is extremely low among captive-born southern white females. Almost all of Southern White Rhinoceros live in South Africa (94.2% live here). Although populations have been established outside their historical range in Kenya and Zambia. Much smaller populations have also been reintroduced into Botswana, Namibia, Swaziland, and Zimbabwe.
Threats They once came to near extinct in the arly 1900's due to hunting and the persuction of farmers. Illegal poaching of their horn for asian medicine and for Yeman handles is the biggest threat towards the subspecies. Although the demand for the horn in Yeman has declined. Poaching pressure is still pretty high though and conservation guard can not be eased.
