Indian Rhino in a Water Hole

The Indian Rhinoceros (Rhinoceros unicornis) is also called Greater One-horned Rhinoceros and Asian One-horned Rhinoceros and belongs to the Rhinocerotidae family. Listed as a vulnerable species, the large mammal is primarily found in parts of north-eastern India and in protected areas in the Terai of Nepal, where populations are confined to the riverine grasslands in the foothills of the Himalayas. Weighing between 2260 kg and 3000 kg, it is the fourth largest land animal and has a single horn, which measures 20 to 57 cm (7.9 to 22 in) in length.

 

The Indian rhinoceros once ranged throughout the entire stretch of the Indo-Gangetic Plain but excessive hunting reduced their natural habitat drastically. Today, about 3,000 rhinos live in the wild, 2,000 of which are found in India's Assam alone.

 

Rhinos are mostly solitary creatures, with the exception of mothers and calves and breeding pairs, although they sometimes congregate at bathing areas. They have home ranges, the home ranges of males being usually 2 to 8 km2 (0.77 to 3.1 sq mi) large and overlapping each other. Dominant males tolerate males passing through their territory except when they are in mating season, when dangerous fights break out. They are active at night and early morning. They spend the middle of the day wallowing in lakes, rivers, ponds, and puddles to cool down. They are very good swimmers. Over 10 distinct vocalizations have been recorded.

 

Indian rhinos have few natural enemies, except for tigers who sometimes kill unguarded calves, but adult rhinos are less vulnerable due to their size. Mynahs and egrets both eat invertebrates from the rhino's skin and around its feet. Tabanus flies, a type of horse-fly are known to bite rhinos. The rhinos are also vulnerable to diseases spread by parasites such as leeches, ticks, and nematodes. Anthrax and the blood-disease septicemia are known to occur.

 

They can run at speeds of up to 55 km/h (34 mph) for short periods of time and are excellent swimmers. They have excellent senses of hearing and smell but relatively poor eyesight.
