Golden Bandicoot (Barrow Island)  |  

Isoodon auratus barrowensis (golden bandicoot (Barrow Island)), family Peramelidae, is a compact marsupial which grows to an average length of 24.5 cm with an average tail length of 10.5 cm. The golden bandicoot (Barrow Island) is slightly smaller and has slightly darker fur than the golden bandicoot (mainland), and weighs between 250 and 600 g when mature. The species is mainly solitary, though home ranges overlap and may alter by seasons, usually increasing in size in drier seasons. Isoodon is currently divided into many species and subspecies though the validity of this
taxonomic approach is debated. Argument regarding the definition of subspecies focuses on whether isolated populations are genetically different subspecies or whether populations have developed morphological traits in response to environmental constraints at respective locations.
