Q. Which is the smallest of all living rhinoceroses and the only Asian rhinoceros with two horns?
Answer:
Sumatran Rhino
Notes: Sumatran rhinos are the smallest of the living rhinoceroses. They are the only Asian rhinoceros with two horns. They are characterised by their long hair and hence are known as the hairy rhinoceros.
With just less than 100 individuals remaining, the Sumatran rhinoceros is one of the world’s most endangered mammal species. Recently, a study found that the remaining populations of the Sumatran rhinoceros display very low levels of inbreeding, which is a good sign for conservation.
