Rhinoceros sondaicus

Help the Javan Rhino

The Javan Rhino is the rarest of the rhino species with fewer than 60 animals surviving in only two known locations: one in Indonesia and the other in Vietnam. Rhinos have been poached from these small populations in recent years and much more intensive protection is needed if this species is to survive. The Javan and the Sumatran compete for the dubious distinction of being the most endangered species of rhino.

Common Names

  • Javan Rhinoceros
  • Asian Lesser One-Horned Rhinoceros: in contrast to the Greater One-Horned Rhino
    (i.e., the Indian Rhino) because of the Javan's smaller size.

Scientific Name and Origin

  • Rhinoceros sondaicus
  • Rhinoceros: from the Greek rhino, meaning "nose" and ceros, meaning "horn"
  • sondaicus: (Latin -icus indicates a locality) referring to the Sunda islands in Indonesia.; "Sunda" means "Java"

Current Javan Rhino Numbers and Distribution

There are currently approximately 60 Javan Rhinos surviving in two widely separate places, one in Java, Indonesia; the other in Vietnam.
