Shortridge's Mastomys is a rare rodent studied around the Okavango Basin in southwestern Africa. Cranial measurements can distinguish it from a close relative.
The study compared 11 cranial measurements across 3 species and used a discriminant function to distinguish this species from co-occurring M. natalensis with 95% accuracy.
The paper reports low population densities, a restrictive habitat preference, and declining habitat quality for this species.
An extinction-risk assessment has not been added yet.
