In response to the dramatic increase in cases of rhino poaching, WWF-SA has launched a national programme to strengthen rhino conservation efforts.
Black rhino - Critically endangered species and beloved animals at risk - Pictures. For millennia, the snow leopard ruled the mountains of China, Bhutan, Nepal, India, Pakistan, Afghanistan, Russia, and Mongolia. It could scale steep slopes with ease, leap six times its body length and wrap its tail around its body to protect itself from the cold. In recent years, however, this powerful cat has become endangered due to several forms of conflict with its sole predator, humans. Animals that snow leopards traditionally hunt, like Argali sheep, are now also hunted by humans and, therefore, harder to come by. This has forced snow leopards to start killing livestock to survive, which has in turn caused local farmers to begin killing snow leopards to protect their livestock.
These retaliatory killings, combined with habitat fragmentation and climate change, have diminished snow leopard populations to somewhere between 4,0.
Rhinoceros - Wikipedia. A rhinoceros (, meaning . Two of these extant species are native to Africa and three to Southern Asia.
Members of the rhinoceros family are characterized by their large size (they are some of the largest remaining megafauna, with all of the species able to reach one tonne or more in weight); as well as by an herbivorous diet; a thick protective skin, 1. They generally eat leafy material, although their ability to ferment food in their hindgut allows them to subsist on more fibrous plant matter, if necessary. 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.
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 then consume them believing the dust has therapeutic properties. The IUCN Red List identifies three of the species as critically endangered. Taxonomy and naming.
BLACK RHINO AN ENDANGERED SPECIES. The name “rhino” conjures up the image of a prehistoric beast, a huge creature with skin of armor. This image is not surprising. BLACK-FOOTED FERRET AN ENDANGERED SPECIES. The rarest native mammal in the United States, the black-footed ferret is a short-legged, slender-bodied weasel. Photograph by Brent Stirton. In a café in Vietnam, a woman grinds a piece of rhino horn. By adding a little water and rubbing the horn over the dish's sandpaper-like. Solutions to rhino poaching - we look at three possible solutions before another African animal becomes extinct. The word rhinoceros is derived through Latin from the Ancient Greek:
The word rhinoceros is derived through Latin from the Ancient Greek: . 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 1. 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 1. 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 1. The Sumatran rhinoceros is the only surviving representative of the most primitive group, the Dicerorhinini, which emerged in the Miocene (about 2.
Interspecific hybridisation of black and white rhinoceros has also been confirmed. However, chromosomal polymorphism might lead to varying chromosome counts. For instance, in a study there were three northern white rhinoceroses with 8. As of 2. 01. 3, the southern subspecies has a wild population of 2. However, the northern subspecies is critically endangered, with as few as three known individuals left in captivity. There is no conclusive explanation of the name white rhinoceros. A popular theory that .
Established in 2010 as a response to the escalating rhino crisis in South Africa, StopRhinoPoaching.com is actively involved in the fight against rhino poaching and.
Females weigh 1,6. The head- and- body length is 3. On its snout it has two horns.
The front horn is larger than the other horn and averages 9. 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. Most of its body hair is found on the ear fringes and tail bristles, with the rest distributed rather sparsely over the rest of the body.
White rhinos have the distinctive flat broad mouth that is used for grazing. This can be confusing, as the two species are not truly distinguishable by color. There are four subspecies of black rhino: South- central (Diceros bicornis minor), the most numerous, which once ranged from central Tanzania south through Zambia, Zimbabwe and Mozambique to northern and eastern South Africa; South- western (Diceros bicornis occidentalis) which are better adapted to the arid and semi- arid savannas of Namibia, southern Angola, western Botswana and western South Africa; East African (Diceros bicornis michaeli), primarily in Tanzania; and West African (Diceros bicornis longipes) which was declared extinct in November 2. Two horns on the skull are made of keratin with the larger front horn typically 5. Sometimes, a third smaller horn may develop. Since then, numbers have been steadily increasing at a continental level with numbers doubling to 4,8.
Current numbers are however still 9. Its thick, silver- brown skin forms huge folds all over its body. Its upper legs and shoulders are covered in wart- like bumps, and it has very little body hair. Grown males are larger than females in the wild, weighing from 2,5.
Shoulder height is 1. Females weigh about 1,9. The record- sized specimen was approximately 3,8. Indian rhinos once inhabited many areas ranging from Pakistan to Burma and maybe even parts of China.
However, because of human influence, they now only exist in several protected areas of India (in Assam, West Bengal, and a few pairs in Uttar Pradesh) and Nepal, plus a few pairs in Lal Suhanra National Park in Pakistan. It is 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 hairless, hazy gray skin falls into folds into the shoulder, back, and rump, giving it an armored appearance.
Its length reaches 3. Adults are variously reported to weigh 9. As of 2. 01. 5, only 5. Ujung Kulon National Park, Java, Indonesia. The last rhino in Vietnam was reportedly killed in 2. It can be found at very high altitudes in Borneo and Sumatra.
Due to habitat loss and poaching, their numbers have declined and it has become the most threatened rhinoceros. About 2. 75 Sumatran rhinos are believed to remain. There are three subspecies of Sumatran rhinoceros: the Western Sumatran rhinoceros (Dicerorhinus sumatrensis sumatrensis), Eastern Sumatran rhinoceros (Dicerorhinus sumatrensis harrissoni) and the 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 (2. 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.
It has been found through DNA comparison that the Sumatran rhinoceros is the most ancient extant rhinoceros, and related to the extinct Woolly Rhinoceros, Coelodonta. In 1. 99. 4 Alan Rabinowitz publicly denounced that governments, NGOs and other institutions were lacking in attempts to conserve the Sumatran rhinoceros. In order to conserve it, they would have to be relocated from small forests to breeding programs where their breeding success could be monitored. In order to boost reproduction, the Malaysian and Indonesian governments could also agree on exchanging the gametes of the Sumatran and (smaller) Bornean subspecies.
There has also been a proposal by the Indonesian and Malaysian governments for a single management unit for these two ancient subspecies. Fossils of Hyrachyus eximus found in North America date to this period. This small hornless ancestor resembled a tapir or small horse more than a rhino.
Three families, sometimes grouped together as the superfamily Rhinocerotoidea, evolved in the late Eocene, namely the Hyracodontidae, Amynodontidae and Rhinocerotidae. Hyracodontidae. Hyracodontidae, also known as 'running rhinos', showed adaptations for speed, and would have looked more like horses than modern rhinos. The smallest hyracodontids were dog- sized; the largest was Indricotherium, believed to be one of the largest land mammals that ever existed. The hornless Indricotherium was almost seven metres high, ten metres long, and weighed as much as 1. Like a giraffe, it ate leaves from trees. The hyracodontids spread across Eurasia from the mid- Eocene to early Miocene. Amynodontidae. The Amynodontidae, also known as .
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. Rhinocerotidae. The family of all modern rhinoceros, the Rhinocerotidae, first appeared in the Late Eocene in Eurasia. The earliest members of Rhinocerotidae were small and numerous; at least 2. Eurasia and North America until a wave of extinctions in the middle Oligocene wiped out most of the smaller species. 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.
Two species survived the most recent period of glaciation and inhabited Europe as recently as 1. Elasmotherium. The woolly rhinoceros appeared in China around 1 million years ago and first arrived in Europe around 6. It reappeared 2. 00,0. Eventually it was hunted to extinction by early humans. Elasmotherium, also known as the giant rhinoceros, survived through the middle Pleistocene: it was two meters tall, five meters long and weighed around five tons, with a single enormous horn, hypsodont teeth and long legs for running. Of the extant rhinoceros species, the Sumatran rhino is the most archaic, first emerging more than 1. The Sumatran rhino was closely related to the woolly rhinoceros, but not to the other modern species.
The Indian rhino and Javan rhino are closely related and form a more recent lineage of Asian rhino. The ancestors of early Indian and Javan rhino diverged 2–4 million years ago. The lineages containing the living species diverged by the early Pliocene (1. Diceros praecox, the likely ancestor of the black rhinoceros, appears in the fossil record.
Young rhinos can however fall prey to big cats, crocodiles, wild dogs, and hyenas.
