Southern Brown Bandicoot, Isoodon obesulus

The southern brown bandicoot (Isoodon obesulus), known locally as the quenda, is a species of marsupial that is classified within the Peramelidae family. It can be found in Southern Western Australia. It is thought that this species holds between one and five subspecies, with I. o. nauticus sometimes being recognized as its only subspecies.

The southern brown bandicoot varies slightly in size, displaying a sexual dimorphism with males reaching an average body length of thirteen inches and a weight of two pounds, while females weigh about 1.5 pounds. The fur of both males and females is course, can vary in color between dark grey to yellowish brown, and is typically whitish in color on the underside.  It has been found that the breeding season of this species depends upon rainfall, with most populations breeding throughout the year. Females give birth to litters containing up to five young, which are weaned at two months of age.

The main threat to this species is habitat loss and predation from introduced predators like the European Red Fox. Despite these threats, many populations continue to hold high numbers. The southern brown bandicoot appears on the IUCN Red List with a conservation status of “least Concern.”
