nilgiri himalayan and arabian are types of which of the animals
Nilgiri tahr Its closest relatives are sheep (genus Ovis). Until 2005, it was placed with the Himalayan tahr (Hemitragus jemlahicus) and the Arabian tahr (Arabitragus jayakari) in the genus Hemitragus. However, it has recently been transferred to a new genus Nilgiritragus because it is genetically more similar to members of the genus Ovis than to other tahrs.[4]
Himalayas Lifted by the subduction of the Indian tectonic plate under the Eurasian Plate, the Himalayan mountain range runs west-northwest to east-southeast in an arc 2,400 kilometres (1,500 mi) long.[2] Its western anchor, Nanga Parbat, lies just south of the northernmost bend of Indus river. Its eastern anchor, Namcha Barwa, is just west of the great bend of the Yarlung Tsangpo River (upper stream of the Brahmaputra River). The Himalayan range is bordered on the northwest by the Karakoram and the Hindu Kush ranges, to the north, the chain is separated from the Tibetan Plateau by a 50–60 kilometres (31–37 mi) wide tectonic valley called the Indus-Tsangpo Suture.[3] Towards the south the arc of the Himalaya is ringed by the very low Indo-Gangetic Plain.[4] The range varies in width from 350 kilometres (220 mi) in the west (Pakistan) to 150 kilometres (93 mi) in the east (Arunachal Pradesh).[5] The Himalayas are distinct from the other great ranges of central Asia, although sometimes the term Himalaya (or Greater Himalaya) is loosely used to include the Karakoram and some of the other ranges.
