Class - Mammalia
Order – Perissodactyla
Family – Rhinocerotidae
Genus - Ceratotherium
Species – C. simum
Common Name – White Rhinoceros, Square-lipped Rhinoceros
White rhinos have no natural predators. Even young rhinos are rarely targeted by predators. Rhinos, even calves, have very tough skin, and the large size and formidable horns of adults are enough to keep most predatory animals from trying their luck.
White rhinos live in savannahs and grasslands. They are grazers that eat mostly grass. They live in groups of roughly a dozen or so rhinos. These groups are called “crashes”. They spend much of their time eating, and also like to wallow in mud when it gets hot.
White rhino pregnancy lasts for about 16 months. The mother will give birth to one calf, which can weigh over 100 pounds at birth.
The largest living rhino species, the white rhinoceros can grow as long as 13 feet, and as tall as six feet at the shoulder. Males can weigh as much as 5,000 pounds, and in rare cases may be much heavier.
White rhinos have large heads and large, stocky bodies with wrinkly skin and minimal hair. The hide is gray or light brown, with only the ears and tail possessing hair. It has three stumpy toes on each foot and a large hump on its shoulders.
The white rhino has two horns on its nose. The larger front horn can grow as long as two feet. The horns are made of keratin, not bone, which is the same material that fingernails are made from.
There are two subspecies of white rhinoceros – the northern white rhino and the southern white rhino.
The origin of the name “white” rhino is a bit of a mystery. Both African rhinoceros species, the white and black rhino, are varying shades of gray in coloration. One popular story proposes that the white rhino’s name was a mistranslation of the Dutch word “wijd”, which means “wide”, referring to the animal’s wide mouth and snout. However, there is little evidence to support this story. To be more accurate, some scientists refer to the white rhino as the “square-lipped” rhinoceros, and the black rhino as the “hook-lipped” rhinoceros.
As a species, the white rhinoceros is considered to be Near Threatened. The southern species is believed to number around 15,000, making them the most plentiful type of rhinoceros on the planet. However, the northern subspecies is Critically Endangered in the wild, and may even be completely extinct.
The biggest threat to the white rhino has historically been illegal hunting. Though it is quite large, it has poor eyesight and is usually not aggressive, making it an easy target for poachers. Its horn is believed to have medicinal uses in traditional Asian medicine, though there is no scientific evidence to support this.
