Ceratotherium Dicerorhinus Diceros Rhinoceros Extinct genera, see text. Two of the extant species are native to Africa and three to Southern Asia. Members of the rhinoceros family are some of the largest remaining megafauna , with all species able to reach or exceed one tonne in weight. Unlike other perissodactyls , the two African species of rhinoceros lack teeth at the front of their mouths, relying instead on their lips to pluck food.
Rhinoceros are killed by some humans for their horns , which are bought and sold on the black market , and used by some cultures for ornaments or traditional medicine. East Asia, specifically Vietnam , is the largest market for rhino horns. By weight, rhino horns cost as much as gold on the black market. People grind up the horns and consume them, believing the dust has therapeutic properties.
Dicerorhinus sumatrensis. The plural in English is rhinoceros or rhinoceroses. The collective noun for a group of rhinoceroses is crash or herd. The name has been in use since the 14th century. The family Rhinocerotidae consists of only four extant genera: Ceratotherium White rhinoceros , Diceros Black rhinoceros , Dicerorhinus Sumatran rhinoceros , and Rhinoceros Indian and Javan rhinoceros.
The living species fall into three categories. The two African species, the white rhinoceros and the black rhinoceros , belong to the tribe Dicerotini, which originated in the middle Miocene , about The species diverged during the early Pliocene about 5 million years ago.
The main difference between black and white rhinos is the shape of their mouths — white rhinos have broad flat lips for grazing, whereas black rhinos have long pointed lips for eating foliage. There are two living Rhinocerotini species, the Indian rhinoceros and the Javan rhinoceros , which diverged from one another about 10 million years ago.
A subspecific hybrid white rhino Ceratotherium s. Interspecific hybridisation of black and white rhinoceros has also been confirmed. While the black rhinoceros has 84 chromosomes diploid number, 2N, per cell , all other rhinoceros species have 82 chromosomes.
However, chromosomal polymorphism might lead to varying chromosome counts. For instance, in a study there were three northern white rhinoceroses with 81 chromosomes. There are two subspecies of white rhinoceros: the southern white rhinoceros Ceratotherium simum simum and the northern white rhinoceros Ceratotherium simum cottoni. However, the northern subspecies is critically endangered, with all that is known to remain being two captive females.
There is no conclusive explanation of the name "white rhinoceros". A popular idea that "white" is a distortion of either the Afrikaans word wyd or the Dutch word wijd or its other possible spellings whyde , weit , etc. The white rhino has an immense body and large head, a short neck and broad chest. The head-and-body length is 3. On its snout it has two horns. The white rhinoceros also has a prominent muscular hump that supports its relatively large head. The colour of this animal can range from yellowish brown to slate grey.
White rhinos have the distinctive flat broad mouth that is used for grazing. The name "black rhinoceros" Diceros bicornis was chosen to distinguish this species from the white rhinoceros Ceratotherium simum. This can be confusing, as the two species are not truly distinguishable by color. An adult black rhinoceros stands 1.
Sometimes, a third smaller horn may develop. During the latter half of the 20th century, their numbers were severely reduced from an estimated 70,  in the late s to a record low of 2, in Since then, numbers have been steadily increasing at a continental level with numbers doubling to 4, by the end of Its upper legs and shoulders are covered in wart -like bumps, and it has very little body hair.
Shoulder height is 1. Indian rhinos once inhabited many areas ranging from Pakistan to Myanmar and maybe even parts of China. However, because of human influence, they now exist in only several protected areas of India in Assam , West Bengal , and a few pairs in Uttar Pradesh and Nepal , plus a pair in Lal Suhanra National Park in Pakistan reintroduced there from Nepal. They are confined to the tall grasslands and forests in the foothills of the Himalayas.
Two-thirds of the world's Indian rhinoceroses are now confined to the Kaziranga National Park situated in the Golaghat district of Assam , India. It is also the least known rhino species. Like the closely related, and larger, Indian rhinoceros , the Javan rhino has a single horn. Its length reaches 3. Though once widespread throughout Asia, by the s they were nearly hunted to extinction in Nepal , India , Burma , Peninsular Malaysia , and Sumatra for the supposed medical powers of their horns and blood.
The last known Javan rhino in Vietnam was reportedly killed for its horn in by Vietnamese poachers. Now only Java contains the last Javan rhinos. It can be found at very high altitudes in Borneo and Sumatra. About Sumatran rhinos are believed to remain. There are three subspecies of Sumatran rhinoceros: the Sumatran rhinoceros proper Dicerorhinus sumatrensis sumatrensis , the Bornean rhinoceros Dicerorhinus sumatrensis harrissoni and the possibly extinct Northern Sumatran rhinoceros Dicerorhinus sumatrensis lasiotis.
A mature rhino typically stands about 1. Like the African species, it has two horns; the larger is the front 25—79 centimetres 9. Males have much larger horns than the females. Hair can range from dense the densest hair in young calves to sparse. The color of these rhinos is reddish brown. The body is short and has stubby legs. The lip is prehensile. Sumatran rhinoceros are on the verge of extinction due to loss of habitat and illegal hunting.
Once they were spread across South-east Asia, but now they are confined to several parts of Indonesia and Malaysia due to reproductive isolation. There were D.
In Alan Rabinowitz publicly denounced governments, NGOs, and other institutions for lacking in their attempts to conserve the Sumatran rhinoceros. To conserve it, they would have to relocate them from small forests to breeding programs that could monitor their breeding success. To boost reproduction, the Malaysian and Indonesian governments could also agree to exchange the gametes of the Sumatran and smaller Bornean subspecies.
The Indonesian and Malaysian governments have also proposed a single management unit for these two ancient subspecies. Plantations for palm oil have taken out the living areas and led to the eradication of the rhino in Sumatra.
Rhinocerotoids diverged from other perissodactyls by the early Eocene. Fossils of Hyrachyus eximus found in North America date to this period. Three families, sometimes grouped together as the superfamily Rhinocerotoidea , evolved in the late Eocene, namely the Hyracodontidae, Amynodontidae and Rhinocerotidae.
The smallest hyracodontids were dog-sized; the largest was Paraceratherium , one of the largest known land mammals that ever existed. Like a giraffe , it ate leaves from trees. Hyracodontids spread across Eurasia from the mid-Eocene to early Miocene. The Amynodontidae, also known as "aquatic rhinos", dispersed across North America and Eurasia , from the late Eocene to early Oligocene. The amynodontids were hippopotamus -like in their ecology and appearance, inhabiting rivers and lakes, and sharing many of the same adaptations to aquatic life as hippos.
The family of all modern rhinoceros, the Rhinocerotidae, first appeared in the Late Eocene in Eurasia. However, several independent lineages survived. Menoceras , a pig-sized rhinoceros, had two horns side-by-side. The North American Teleoceras had short legs, a barrel chest and lived until about 5 million years ago. The last rhinos in the Americas became extinct during the Pliocene.
Modern rhinos are thought to have begun dispersal from Asia during the Miocene. The woolly rhinoceros appeared in China around 1 million years ago and first arrived in Europe around , years ago. It reappeared , years ago, alongside the woolly mammoth , and became numerous. Elasmotherium was two meters tall, five meters long and weighed around five tons, with a single enormous horn, hypsodont teeth and long legs for running.
Both the Coelodonta and Elasmotherium survived through the late Pleistocene when climate fluctuations, increased predation by newer predators such as hyenas and human hunting led to their extinction.
The Sumatran rhino was closely related to the woolly rhinoceros, but not to the other modern species. The ancestors of early Indian and Javan rhino diverged 2—4 million years ago. The origin of the two living African rhinos can be traced to the late Miocene 6 mya species Ceratotherium neumayri. The lineages containing the living species diverged by the early Pliocene 1.
Adult rhinoceros have no real predators in the wild, other than humans. Young rhinos can however fall prey to big cats , crocodiles , African wild dogs , and hyenas. Although rhinos are large and have a reputation for being tough, they are very easily poached; they visit water holes daily and can be easily killed while they drink.
As of December , poaching increased globally while efforts to protect the rhino are considered increasingly ineffective. South African officials have called for urgent action against poaching after poachers killed the last female rhino in the Krugersdorp Game Reserve near Johannesburg.
The Namibian government has supported the practice of rhino trophy hunting as a way to raise money for conservation. Hunting licenses for five Namibian Black rhinos are auctioned annually, with the money going to the government's Game Products Trust Fund.
Some conservationists and members of the public however oppose or question this practice.

It would not be fatal—the primary deterrent is the knowledge that the treatment has been applied, communicated by signs posted at the refuges. The original idea grew out of research into the horn as a reservoir for one-time tick treatments, and experts selected an acaricide they think is safe for the rhino, oxpeckers , vultures , and other animals in the preserve's ecosystem.
The UK charity organization Save the Rhino has criticized horn poisoning on moral and practical grounds. The organization questions the assumptions that the infusion technique works as intended, and that even if the poison were effective, whether middlemen in a lucrative, illegal trade would care much about the effect it would have on buyers.
Another way to undercut the rhinoceros horn market has been suggested by Matthew Markus of Pembient , a biotechnology firm. He proposes the synthesis of an artificial substitute for rhinoceros horn. Greek historian and geographer Agatharchides 2nd century BC mentions the rhinoceros in his book On the Erythraean Sea. There are legends about rhinoceroses stamping out fire in Burma , India , and Malaysia.
The mythical rhinoceros has a special name in Malay , badak api , wherein badak means rhinoceros, and api means fire. The animal would come when a fire was lit in the forest and stamp it out. This legend was depicted in the film The Gods Must Be Crazy , which shows an African rhinoceros putting out two campfires.

Rhinos' feet are surprisingly sensitive. Unfortunately, when the creatures are brought to zoos and held in concrete or asphalt enclosures, the nails wear down and the rhinos have to walk on their foot pads.
As a result, they often get swollen, sore and cracked feet that can quickly become infected. Javan rhino image by Lawrence Anson Wong's Flickr. Rhinos need our help. All rhinos are in danger at this point. In fact, there are only about Sumatran rhinos, 17, white rhinos and 2, Indian rhinos alive today.

While loss of habitat has been a problem for the beasts, their biggest threat is poaching and, unfortunately, this problem is only getting worse. In , a record number of rhinos, to be exact, were killed in South African National Parks, and in the number increased to To stop the killing, reserves have tried a variety of tactics, including removing the horns altogether the rhinos rarely need to use them to defend themselves , using a fluorescent pesticide on the horns to protect the rhino from bugs, catching poachers at the airports, and applying poison to deter buyers of the horn.
In some case, mercenaries even kill suspected poachers on site. No matter what officials do to try to stop the killers though, the lure of massive amounts of money, especially during the global recession, is just too powerful. So how much are rhino horns worth? Well, one average size horn can easily bring in a quarter of a million dollars. Sumatran rhino image courtesy of Wikipedia user Ltshears. One of the saddest things about the murder of these magnificent beasts is the fact that their horns, despite some Eastern medicinal practitioners' claims, are essentially useless as a medical treatment.
There is hope though. Remember that there are up to 17, white rhinos?
Greater One-Horned Rhino | Species | WWF
Once widespread across the entire northern part of the Indian sub-continent, rhino populations plummeted as they were hunted for sport or killed as agricultural pests. This pushed the species very close to extinction and by the start of the 20 th century, around wild greater one-horned rhinos remained.
The recovery of the greater one-horned rhino is among the greatest conservation success stories in Asia. Thanks to strict protection and management from Indian and Nepalese wildlife authorities, the greater one-horned rhino was brought back from the brink. Today populations have increased to around 3, rhinos in northeastern India and the Terai grasslands of Nepal.
The greater one-horned rhino is identified by a single black horn about inches long and a grey-brown hide with skin folds, which gives it an armor-plated appearance. The species is solitary, except when adult males or rhinos nearing adulthood gather at wallows or to graze.
Males have loosely defined home ranges that are not well defended and often overlap. Rhinos share their homes with other valuable plants and animals. When we protect greater one-horned rhinos, we also help protect these other species. These rhinos are also a symbol of national pride in the countries where they are found, which inspires environmental stewardship among local communities. These communities also benefit from the revenue generated through rhino ecotourism.
Today, the need for land by a growing human population is a threat to the species. Many of the protected areas with rhinos have now reached the limit of the number of individuals they can support.
Poaching for the illegal trade in rhino horn remains the biggest threat to the greater one-horned rhino. Although there is no scientific proof of its medical value, the horn is used in traditional Asian medicines, primarily for the treatment of a variety of ailments including epilepsy, fevers, and cancer. Extensive illegal trade persists throughout Asia despite protections and bans on international trade of rhino horn.
High population density in some parks leads to lower breeding rates. Also, concerns exist about long term viability of sub-populations due to lack of genetic diversity. The enormous reduction in the range of rhinos was mainly caused by the disappearance of alluvial plain grasslands.
Many of the protected areas where rhinos live have reached the limit of the number of individuals they can support. Rhinos reportedly kill several people each year in India and Nepal. Newborn rhino calf trailing its mother in a remote section of Manas National Park in the northeast corner of India.
WWF seeks to create three new populations of at least 10 greater one-horned rhinos each in the next five years. As of , Manas was home to 29 rhinos. In India, WWF aims to expand the number of greater one-horned rhinos to 3,—spread out over seven protected areas—by In Nepal, the goal is to increase the rhino population from to individuals in the coming years.
Two of the translocated females gave birth within a few months—an encouraging sign that they are adjusting well to the new habitat. WWF helps to strengthen security measures and provides critical support for anti-poaching efforts at key sites including Kaziranga National Park and Pobitora and Laokhowa-Burachapori Wildlife Sanctuaries.
As rhino populations increase, they need additional space to live and breed. WWF and partners restore rhino habitat in Nepal to increase rhino numbers and improve connectivity between protected areas.
Chitwan National Park's population of greater one-horned rhinos is the second largest population of this species in the world, after India's Kaziranga National Park. In Kaziranga National Park, WWF works to secure habitat corridors so that rhinos have access to higher areas outside of the park during annual floods. The protected areas of India and Nepal, where rhinos reside, are surrounded by dense human populations.
It is vital to ensure that communities that live around rhino reserves are sympathetic to, and benefit from, the rhinos in their midst. WWF supports several projects to improve local livelihoods, like the successful community-run Marmelous juice factory in Khata, Nepal. We help decrease conflict between people and rhinos by encouraging farmers to plant unpalatable species like mentha mint that generates money for the communities and supports community-based antipoaching operations.
WWF partners with national governments to strengthen wildlife laws and their enforcement, and fund antipoaching equipment and operations in protected areas. In response to a poaching spike in Nepal in , WWF increased the number of security posts from eight to We also engaged ex-army and police to patrol vulnerable points outside protected areas.
Local youth volunteered to guard individual rhinos through the night. WWF relayed the information collected by these allies to key government departments so they could take action where needed. In , Nepal hosted the first symposium focused on getting to zero poaching. WWF and TRAFFIC, the wildlife trade monitoring network, work to stop trafficking of rhino horn by funding antipoaching patrols and supporting intelligence networks in strategic locations to prevent rhinos from entering black markets in Asia.
