The greater one-horned rhinoceros is a heavy, grey-brown animal with pinkish folds in the skin and a single horn on the snout, reported at up to about 60cm. The upper legs and shoulders are covered in wart-like bumps, and it is almost hairless apart from the eyelashes, ear fringes and tail brush. Among Asian land mammals only the Asian elephant is larger, and the biggest individuals are reported at around 4,000kg (Wikipedia, general species account).
It is a grazer of the alluvial grasslands of the Terai and the Brahmaputra basin, and in Nepal it survives in the southern lowlands. Adults are largely solitary and meet mainly to breed or at wallows and feeding areas. A female bears a single calf after about 15.7 months, with 34 to 51 months between births. Poaching remains a continuing threat. Nationally Endangered (Nepal National Red List 2011).
