Monkeys have a number of adaptations that help them maintain their body temperature. These adaptations include:
* A thick layer of fur: Fur helps to insulate the body and keep heat from escaping.
* A high metabolic rate: A high metabolic rate means that the body produces heat quickly.
* The ability to sweat: Sweating helps to cool the body down by evaporating water from the skin.
* The ability to pant: Panting helps to cool the body down by increasing the flow of air over the lungs.
These adaptations allow monkeys to survive in a wide range of environments, from the hot tropics to the cold mountains.
