The typical lifespan of Sumatran rhinoceroses (Dicerorhinus sumatrensis) in their natural habitat is approximately 35 to 40 years. However, in captivity, they have the potential to live longer, with certain individuals reaching their 50s or even early 60s. It is important to emphasize that these are average statistics, and the lifespan of each individual can differ based on various factors such as environment, well-being, and availability of resources. The preservation of Sumatran rhinoceroses is currently endangered due to the loss of their natural habitat, illegal hunting, and a decline in population numbers. Consequently, conservation efforts are imperative for their continued existence in the long run.
