How many types of species in rhino?

There are two types of species in rhino: they are white and black. The white has square-lipped rhino and hooked-lipped rhino. The black rhino has three toes on each foot. Both the black and white rhino have two horns.

How many types of species in rhino?
5 remaining species (2 African,3 Asian)








White or Square-lipped rhinoceros, (Ceratotherium simum)





There are two subspecies of the white rhino -- the northern white rhino, which is nearly extinct, and the southern white rhino, which is the most common of all rhinos. The white rhino is actually gray. Its name probably stems from the mistranslation of the Dutch word for "wide" describing its upper lip. It lives on the open plains of Africa. The largest of the rhinos, it stands more than 6 feet tall and weighs 6,000 to 8,000 pounds. It also has the longest horn, averaging 18 inches to 4 feet.





Black rhinoceros, (Diceros bicornis)





The black rhino also lives in Africa, but in a variety of habitats from the dense rainforests to the dry scrublands. Once numerous in eastern and southern Africa, it is now only found in national parks and game reserves. The black rhino stands more than 5 l/2 feet tall and weighs up to 4,000 pounds. Its front horn averages 18 inches to 4 feet.





Indian rhinoceros, (Rhinoceros unicornis)





The Indian rhino weighs the same as the black rhino -- about 4,000 pounds -- but stands about 6 feet tall. This rhino was once found throughout most of India, particularly in lush river valleys. Today, it survives only on eight reserves in India and Nepal. Living in swampy areas, it eats marsh grasses and aquatic plants.





Sumatran rhinoceros, (Dicerorhinus sumatrensis)





The Sumatran rhino is the only Asian rhino species with two horns and the only rhino with hair on its body. The front horn averages 15 to 20 inches and the second may be hardly noticeable. It stands about 4 l/2 feet tall and weighs 750 to 2,000 pounds. There are a few Sumatran rhinos left in Burma, Malaysia, Thailand, and Sumatra. They live in dense forests and feed on plants at the forest edges and in mountain clearings.





Javan rhinoceros, (Rhinoceros sondaicus)





Like the Sumatran, the Javan rhino also lives in dense forests, feeding at forest edges and mountain clearings on bamboo, fruit, and other plants. There are fewer than 100 Javan rhinos on a game reserve in western Java, and many believe they are extinct in the wild. Javan rhinos weigh up to 3,000 pounds and measure 4 l/2 to 5 l/2 feet tall.
Reply:2. Glad i could help.

Reply:The Black Rhinoceros is much smaller than the White Rhinoceros, and has a pointed mouth, which they use to grasp leaves and twigs when feeding. White Rhinoceros have square lips used for eating leaves. The Black Rhinoceros can also be recognized from the White Rhinoceros by its smaller skull and ears. Black Rhinoceros also do not have a distinguishing shoulder hump like the White Rhinoceros.





There are four subspecies of the black rhinoceros:





South-central (Diceros bicornis minor) which are the most numerous, and once ranged from central Tanzania south through Zambia, Zimbabwe and Mozambique to northern and eastern South Africa.


South-western (Diceros bicornis bicornis) 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) which had a historic distribution from south Sudan, Ethiopia, Somalia down through Kenya into north-central Tanzania. Today, its range is limited primarily to Tanzania.


West African (Diceros bicornis longipes) is the rarest and most endangered subspecies. Historically, it once occurred across most of the west African savanna. Until recently, only a few individuals survived in northern Cameroon, but on July 8, 2006 the World Conservation Union declared the subspecies to be tentatively extinct.





The White Rhino is the most common of all rhinos and consists of two subspecies, with the northern subspecies being rarer than the southern.
Reply:The rhinoceros commonly called rhino for brevity) is any of five surviving species of odd-toed ungulates in the family Rhinocerotidae. All five species are native to Africa, the Middle East, and southern Asia. Most species of rhino are endangered. Rhinoceros is also one of the genera in this family.
Reply:wrong there are 5 species. black, white, javan, sumatran and the indian rhino. these can then be divided into sub-species so there are more than you think.
Reply:Are you sure they are different species?
Reply:I work at the Natural History Museum in London %26amp; have been fortunate to study the rhino quite closely. Living today, are five different species of Rhinoceros. The largest is the White Rhinoceros, Ceratotherium simum, which weighs in at up to 2.3 tonnes. Second place is held by the Indian Rhinoceros, Rhinoceros unicornis, %26amp; weighing in at up to 2.2 tonnes. Third is the Javan Rhinoceros, Rhinoceros Sandaicus, which weighs only 1.4 tonnes. Then in fourth place, is the Black Rhinoceros, Diceros bicornis, which weighs up to 1.3 tonnes. And last but not least is the little Sumatran Rhinoceros, Dicerohornis sumatrensis; a light weight by Rhino standards, tipping the scales at less than 800 kilogrammes. However, over many millions of years, there have been many different types of Rhino. The largest ever recorded, also holds the record as the largest land mammal that has ever lived. The Indricotheres, were gigantic hornless rhinos. The largest was Paraceratherium, previously called Indricotherium %26amp; Baluchitherium. Their fossils are found across Eurasia, of which the most famous are found in the Hsanda Gol formation. The males were larger than the females, %26amp; reached almost 4.5 metres (15 feet) at the shoulder %26amp; weighed in at 15 - 20 tonnes. Females would have perhaps weighed in at 11 tonnes. The males are also known to have had heavier %26amp; more domed skulls than the females, which may have been used in butting contests. This may have been for rights to females, as Black Rhino are known to be very aggressive, stabbing each other with their horns. The Indricotheres lived approximately 30 - 25 million years ago, during the Oligocene epoch. Another 2 were the Elasmotherium, known otherwise, as the Giant Unicorn Rhinoceros. Fossils of the Elasmotherium are not too common, %26amp; information is hard to come by. But if I am correct, the giant rhino, measured up to 8 feet at the shoulder %26amp; weighed a hefty 7 tonnes. A common type of ancient, yet also very recent type of rhino, is the Woolly Rhinoceros, Coelodonta antiquitatis. This species has been found all across Europe %26amp; are sometimes found by accident, such as a recent find by a builder working on a digger. Apparently, however, they never did reach Ireland or North America, although, the best specimens are discovered in the Siberian permafrost. The horn also, of this particular beast was shaped in a laterally-flattened way. More or less like a blade, which hung down at an angle, for shovelling snow aside, as the animal is known also to have fed on grass. the horn of the beast also measured up to 6.5 feet. Amazingly also, they say that a Rhino's horn is not made of real horn, but of congealed hairs. Hair is made from a protein substance called Ceratin (Keratin). The sentence is Greek %26amp; translates to English as 'Made of horn'. Hair, fingernails, %26amp; even the sheaths, which covered the claws %26amp; horns of Dinosaurs themselves are all made of Ceratin. So basically, the animal's horn is made of horn. Yet more surprisingly, the name Rhinoceros, is formed of 2 Greek words also, which translate to English as 'Nose Horn'. This is all the information I have so far, but I hope it's been helpful. Keep it real.
