The Sumatran rhinoceros or Hairy Rhinoceros is the smallest rhinoceros, although it is still a large mammal; it stands 3.67–4.76 ft. high at the shoulder, with a head-and-body length of 7.7 to 10.4 ft. and a tail of 14 to 28 in.

They are now critically endangered, with only five substantial populations in the wild: four in Sumatra and one in Borneo.

Hairy Rhinoceros numbers are difficult to determine because they are solitary animals that are widely scattered across their range, but they are estimated to number fewer than 80.

The first documented Sumatran rhinoceros or Hairy Rhinoceros was shot 9.9 mi. outside Fort Marlborough, near the west coast of Sumatra, in 1793.

Drawings of the animal, and a written description, were sent to the naturalist Joseph Banks, then president of the Royal Society of London, who published a paper on the specimen that year.

In 1814, the species was given a scientific name by Johann Fischer von Waldheim.

The specific epithet sumatrensis signifies “of Sumatra”, the Indonesian island where the rhinos were first discovered.

Carl Linnaeus originally classified all rhinos in the genus, Rhinoceros; therefore, the Hairy Rhinoceros was originally identified as Rhinoceros sumatrensis or sumatranus.

Joshua Brookes considered the Sumatran rhinoceros with its two horns a distinct genus from the one-horned Rhinoceros, and gave Hairy Rhinoceros the name Didermocerus in 1828.

Constantin Wilhelm Lambert Gloger proposed the name Dicerorhinus in 1841.

In 1868, John Edward Gray proposed the name Ceratorhinus. Normally, the oldest name would be used, but a 1977 ruling by the International Commission on Zoological Nomenclature established the proper genus name as Dicerorhinus.

Like both African species, it has two horns; the larger is the nasal horn, typically 5.9–9.8 in., while the other horn is typically a stub. A coat of reddish-brown hair covers most of the Hairy Rhinoceros or Sumatran rhino’s body.
