This spiny rat lives in central South America. Most animals have the usual coat, but some individuals with predominantly white fur have been reported; it uses densely vegetated places.
A study reported individuals with predominantly white coats in addition to normally colored animals. The paper describes this pattern as a possible case of partial albinism.
It lives in places with dense vegetation, which the paper says can shelter it from predators and provide high-quality food.
An extinction-risk assessment has not been added yet.
