Bridges' degu (Octodon bridgesi) is a species of rodent in the family Octodontidae. It is found in Argentina and Chile, most typically in southern Chile.[2] The species was named after Thomas Bridges, a Victorian botanist who sent specimens to the British Museum for identification.[3]
Biology and physiology
Unlike its close relative the common degu, Bridges' degu is nocturnal (active at night).[4]
Bridges' degu has deep molar indentaions and has a deep fold on the inside of the last molar.[5]
Habitat
The species is less widely distributed in Chile than the common degu and inhabits rocky, forested areas[5] and some open farmland,[2] although it is far less well adapted for digging[4] but does have some climbing ability.[6] Deforestation may be contributing to the decline of this species.[4]
In Argentina it also inhabits southern beeches forests.[7]
