Bridges's degu (Octodon bridgesi) is a species of rodent in the family Octodontidae.[2] It is found in Argentina and Chile, most typically in southern Chile.[3] The species was named after Thomas Bridges, a Victorian botanist who sent specimens to the British Museum for identification.[4]

Biology and physiology[edit]

Unlike its close relative the common degu, Bridges' degu is nocturnal (active at night).[5]

Bridges's degu has deep molar indentations and has a deep fold on the inside of the last molar.[6]


The species is less widely distributed in Chile than the common degu and inhabits rocky, forested areas[6] and some open farmland,[3] although it is far less well adapted for digging[5] but does have some climbing ability.[7] Deforestation may be contributing to the decline of this species.[5]

In Argentina it also inhabits southern beeches forests.[8]
