@DavidBrown the Singapore Zoo has never held Sumatran rhinos. The last time Sumatrans were present in captivity in Singapore was probably in the 1960s, pre-dating the Singapore Zoo.
@Zooish That's interesting that there were pre-Sinagpore Zoo captive Sumatran rhinos in Singapore! Where would they have been kept? Was there an older zoo predating the present zoo complex?
