Greater one-horned rhino
(Rhinoceros unicornis)
The recovery of the greater one-horned rhino, or Indian, rhino is a conservation success story Thanks to strict protection by government authorities in India and Nepal, rhino populations have rebounded from fewer than 100 individuals to more than 4,000 today.
The species derives its name from its single large horn. The “tank-like” appearance of the skin resembles grey plates of armor with rivets.
