Sumatran rhinoceroses (Dicerorhinus sumatrensis) are plant-eaters, which means they primarily consume plant material as their main source of nutrition. Their diet mainly consists of a variety of plant species, including foliage, sprouts, produce, and tree covering. They are specialized eaters that have adaptations for nibbling on vegetation in their forest habitats. While plant-eating is their primary feeding strategy, Sumatran rhinoceroses may occasionally consume small amounts of earth or minerals found in muddy pools, but this does not classify them as animals that eat both plants and animals. Overall, they are considered strict plant-eaters.
