Sumatran rhinoceroses protect themselves through a blend of bodily characteristics and actions. They possess a dense hide that acts as a barricade against assaults, and their tusks can be utilized for striking predators. When confronted with danger, they exhibit aggression by snorting, stomping, and charging. Their dusky, camouflaged fur aids in blending into their surroundings, and they can swiftly maneuver to avoid threats. Vocalizations, such as growls and snorts, function as intimidation strategies. However, as a result of their critically endangered status, their capacity to defend themselves is further jeopardized, underscoring the importance of conservation efforts to ensure their survival.
