The moon-faced degu is a rodent from the octodont family. This animal inhabits rocky areas of the mountains in South America.
The moon-faced degu differs from its lowland relatives with dense fur and adaptation to cold rocky mountains. It disperses plant seeds and serves as food for local predators.
