Rhinoceros

 

This week’s hooved animal is the rhinoceros or rhino the word rhinoceros is a combination of two Greek words – rhino (nose) and ceros (horn).

There are five living species of rhinoceros – white, black, greater one-horned, Javan and Sumatran. In addition, a number of other animals have rhinoceros as part of their names, including the rhinoceros auklet, rhinoceros beetle, rhinoceros chameleon, rhinoceros cockroach, rhinoceros fish, rhinoceros hornbill, rhinoceros iguana, rhinoceros rat snake, rhino shrimp, and rhinoceros viper. All of them have horn-like appendages on their noses.

They can be found in several countries across both Africa and Asia. In Africa, you can find them in Angola, Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe. In Asia, they can be found in India, Indonesia, Nepal, and Vietnam. 

The two main species of rhino in Africa are the black rhino and the white rhino. Black rhinos are found in 12 African countries, with the largest populations in Namibia, South Africa, Kenya, and Zimbabwe. White rhinos are found in 11 African countries. 

Asia is home to the greater one-horned rhino, Javan rhino, and Sumatran rhino. You can find them in India, Indonesia, Nepal, and Vietnam. 

A rhino’s horn is not attached to its skull. It is actually a compacted mass of hairs that continues to grow throughout the animal’s lifetime, just like our own hair and nails. The longest horn on record belonged to a white rhino and measured just under 152cm or 60 inches, which is five feet, and I am only four foot eleven inches tall.

The rhinoceros's closest living relative is the tapir. Horses and zebras are also related, but less closely than tapirs. All three belong to the group of odd-toed ungulates, known as Perissodactyla. Really horses and zebras that sounds weird.

The white rhino’s name comes from the Afrikaans word “wyd,” which means “wide” and describes its mouth. Early English settlers in South Africa misinterpreted the “wyd” for “white”. Black rhinos may have received their name from the dark wet mud in their wallows that made them appear black in colour. Both species are gray in colour, the famous Blue Rhino, corporate logo for the well-known propane tank company, is entirely a figment of its founder’s imagination.

After mating, adult male and female rhinos typically go their separate ways. After the calf is born, it will spend a couple of years or more in the company of its mother, and perhaps associate with other females and their calves, but the father rhino is not part of the standard social group.

They are not generally considered friendly to humans, although they are not inherently aggressive. They prefer to be just left alone and will only charge if they feel threatened or are protecting their young. Female rhinos, especially those with calves, can be particularly dangerous in the wild. While they may not intentionally seek to harm humans, their size and power make them a serious threat if they do charge. 

The live anywhere between 35 and 50yrs depending on the breed.

All five species of rhinos are herbivores, eating mainly vegetation. They spend most of their time browsing and grazing through their natural habitat in search of plants and grasses to eat.
