Edward's long-clawed akodont is a small, partly subterranean rodent of the Patagonian steppe. Direct observations above ground are sparse.
A photographed animal in southern Chile had a chestnut back, orange tones on the flanks, and a sharply separated whitish-gray belly. Its small ears were hidden in the fur, and its tail was bicolored.
It is semi-fossorial, and its underground habits may make it difficult to detect in trapping surveys. Many localities are known from raptor pellets, so details of its ecology remain limited.
An extinction-risk assessment has not been added yet.
