In their natural habitat, Sumatran rhinoceroses typically live for approximately 35 to 40 years. Nonetheless, this duration can fluctuate based on multiple factors, including the quality of their surroundings, the accessibility of resources, and the risks posed by poaching or habitat destruction. In captivity, Sumatran rhinoceroses have been observed to have a lengthier lifespan, with certain individuals surviving into their 40s or even 50s. The longevity of these creatures is affected by their general well-being, genetic elements, and their capacity to evade or conquer various dangers in their surroundings.
