The short-nosed bandicoots (genus Isoodon) are marsupials that belong to the group called Peramelemorphia. They live in different parts of Australia. Scientists who study their genes think that short-nosed bandicoots became different from long-nosed bandicoots about eight million years ago, during a time called the Miocene. They also changed and grew into many types about three million years ago, during the late Pliocene.[2]

Species and subspecies

The IUCN lists only three species in this group,[3] but Australian experts say there are five species. They also say that two subspecies of Isoodon obesulus should be counted as full species.[4][5]

The five species are:

  • Golden bandicoot (Isoodon auratus)
  • Quenda or Western brown bandicoot (Isoodon fusciventer)[6]
  • Northern brown bandicoot (Isoodon macrourus)
  • Southern brown bandicoot (Isoodon obesulus)
  • Cape York brown bandicoot (Isoodon peninsulae)[7]
