Thermoregulatory Function Beyond communication, the proboscis plays a critical role in thermoregulation. This biological air-conditioning system is essential for maintaining a stable internal temperature during the heat of the day, allowing the monkey to remain active and conserve vital energy.
The proboscis, in conjunction with a large abdomen, houses the necessary bacteria to break down toxins and extract maximum energy from their leafy meals. Listed as Endangered on the IUCN Red List, their populations are fragmented and declining.
