Bina is estimated to have been born around 1985. She is the oldest female at the sanctuary and is the oldest living captive Sumatran rhinoceros.

In 2001, Andalas was the first Sumatran rhino born in captivity in more than
112 years. He is the first in a long line of Sumatran rhinos that conservationists hope will be bred in captivity. Eventually, they also hope to introduce him back into the wild.

Ratu was born around 2000 in Way Kambas National Park, the protected area where the sanctuary is located. In 2005, there were reports of her wandering around a nearby village. For her safety, she was captured. Ratu was chosen as the primary breeding female with the sanctuary’s young male, Andalas.

In 2003, Rosa was spotted wandering through villages, looking for food near one of the national parks. In 2005, she was moved to the sanctuary where she could be protected from poachers.

Andatu was born in 2012 at the Sumatran Rhino Sanctuary. Andatu is the first rhino ever born in captivity in Indonesia. He weighed approximately 27 kilograms (60 pounds) at birth, but now tops 450 kilograms (1,000 pounds).

Harapan (Harry) was born at the Cincinnati Zoo in 2007. His parents were part of an international breeding program. Harry was moved to the Sumatran Rhino Sanctuary in 2015. His big brother is Andalas.

Delilah was born in 2016 at the sanctuary. She is Ratu’s second calf and the second rhino ever born in captivity in Indonesia. She weighed 20 kilograms (45 pounds) at birth. Now almost fully grown, Delilah will soon weigh more than half a ton.
