Begum was one of at least seven specimens of the extinct subspecies D. The female, named "Begum", survived until 1900, setting the record of lifespan for a captive rhino. The London Zoo acquired a male and female in 1872 that had been captured in Chittagong in 1868. There has not been a specimen born in a zoo since a single successful birth in the Alipore Zoological Gardens of India in 1889. Northern Sumatran rhinoceroses, like the other two subspecies, do not live outside of their ecosystem and do not breed well in captivity. In captivity A female Northern Sumatran rhinoceros, "Begum", in London Zoo from 15 February 1872 to 31 August 1900. It is also possible northern hairy rhinoceros still live in Taman Negara National Park from Peninsular Malaysia, though the survival of the Peninsular Malaysia population is highly doubtful. Unconfirmed reports suggest a small population of Northern Sumatran rhinoceros may still survive in Myanmar, but the political situation in the country has prevented verification. Although the species was declared extinct in Myanmar in the 1980s, sightings of Sumatran rhinoceroses were recently reported on multiple occasions. The northern hairy rhinoceros was declared extinct in India, Bangladesh, China and other countries in the 1920s, and yet again in 1997 in northeast India, though it is claimed that they persist at the Tamanthi Wildlife Sanctuary of Myanmar. It ranged as far as from the Indochinese peninsula, eastern India, the eastern Himalayas of Bhutan, and Bangladesh to Inner Mongolia in northern China. The Northern Sumatran rhinoceros was the most widespread of the Sumatran rhinoceroses. It also inhabited hilly areas, near rivers, steep upper valleys and mountains. The Northern Sumatran rhinoceros lived in tropical rainforests, swamps, cloud forests, jungles and grasslands. However, it may have less hair on the body than the Western Sumatran rhinoceros. It has longer hair on the ears and longer horns. The Northern Sumatran rhinoceros is the largest subspecies. However, it remained a subspecies as the northern Sumatran rhinoceros was significantly larger, with unusual longer hair on the ears, and longer and bigger horns. There was a debate whether the Dicerorhinus sumatrensis lasiotis specimen should be considered as a separate subspecies from the similar nominate Dicerorhinus sumatrensis sumatrensis specimen from Indonesia. The Northern Sumatran subspecies was also called hairy-eared Sumatran rhinoceros or ear-fringed rhinoceros for that reason. The name lasiotis is derived from the Greek for "hairy-ears", as the Northern Sumatran rhinoceros has remarkable longer fur on the ears. The mainland subspecies of the Sumatran rhinoceros was given the name Dicerorhinus sumatrensis lasiotis. Taxonomy A depiction of the Northern Sumatran rhinoceros by Friedrich Wilhelm Kuhnert, 1927 As of 2008, it is considered as "Critically Endangered" by IUCN. While it has been officially declared as extinct on multiple occasions in early 20th century, it has been reported that small populations might still exist in the wild, such as in Burma and the Malaysian Peninsula, though it is highly doubtful. The Northern Sumatran rhinoceros ( Dicerorhinus sumatrensis lasiotis), also known as Chittagong rhinoceros or northern hairy rhinoceros was the most widespread subspecies of Sumatran rhinoceros, as well as the only known subspecies native to mainland Asia.
