The moon-toothed degu (Octodon lunatus) is a species of rodent in the family Octodontidae.[2] It is endemic to Chile, occurring in mountainous areas along the Pacific coast in the central part of the country.[1][3]
Biology and physiology
[edit]Unlike its close relative the common degu, the moon-toothed degu is nocturnal (active at night).[4] The ventral fur of this species has been found to be much less reflective of UV light than other octodontids,[5] most likely as a result of its nocturnal habits.
The moon-toothed degu has deep molar indentations but lacks a fold on the inside of the last molar.[6]
Habitat
[edit]The species is less widely distributed in Chile than the common degu and inhabits dense scrubland near the coast.[3] Habitat ranges from sea level to 1,200 m in the Andes.[5]
