What do Proboscis Monkeys eat?

Proboscis monkeys are predominantly herbivorous and rely on leaves as the primary component of their diet. Leaves from various tree species, which may include Terminalia, Ficus, and Campnosperma, are eaten. They also enjoy other plant materials such as unripe fruits, flowers, and occasionally seeds. Their elongated skulls, which house extensive sinuses and a large nasal cavity, are particularly adapted for extracting nutrients from leaves.

In addition to leaves, Proboscis monkeys may consume fruits from time to time, with particular preferences for figs, rambutans, and mulberries. Although fruit consumption contributes to their diet, it is not as consistent as leaf consumption. Occasionally, they are also known to feed on insects such as ants and termites, providing a source of protein.

It's important to note that the diet of Proboscis monkeys can vary depending on the specific habitat they reside in and the availability of food sources. However, their diet is primarily focused on leaves and plant material.
