Müller's rat, also called Müller's giant Sunda rat, is a large murid in the genus Sundamys. An adult female type specimen from eastern Kalimantan measured 20.7 cm from head to body and had a 26.2 cm tail, for a total length of 46.9 cm. These are measurements of one museum animal, not a species-wide average (Smithsonian National Museum specimen record).
It is the most widespread member of Sundamys, ranging from peninsular Myanmar through Thailand and Malaysia to Borneo, the Philippines and numerous islands on the Sunda Shelf. Specialist review identifies it as the sole Sundamys occurring in the Myanmar–Thai–Malaysian peninsula study area; detailed ecology and breeding figures were not available in the opened sources and are omitted (specialist review of peninsular murids).
