- The golden bandicoot has a high reproductive rate with a gestation period of only 12.5 days.
- Like most other bandicoots, golden bandicoots have fused toes on their hind feet which form a comb that they use for grooming.

Golden bandicoot description
The golden bandicoot is a small omnivorous marsupial found in Australia (4). This mammal is rat-like in appearance, with a small hunched body posture and a long tail. It has large muscular hind limbs, short forelimbs and forefeet with three toes bearing flat claws. Unlike other marsupials, bandicoots have fused toes on their hind feet, which form a comb for grooming (3). Most bandicoots have noticeably long snouts and large ears. However, this species belongs to the genus Isoodon, the short-nosed bandicoots, which have shorter muzzles (3). The ears are small and rounded, and females have a rear-opening pouch containing eight teats (3). As its name suggests, this small marsupials fur is a golden-brown colour (3).

Golden bandicoot biology
The golden bandicoot is a nocturnal marsupial. It constructs a nest in dense vegetation or in logs, using sticks, leaves and grass, in which it rests during the day (2). This marsupial’s night vision and sense of smell are well-developed. It forages for insects, small reptiles and roots at night (3).
Bandicoots are notable for having one of the highest reproductive rates of all marsupials (3). The gestation period lasts only 12.5 days and is one of the shortest gestation periods of all mammals (4). Females give birth to two to three young. The offspring crawl into the mothers pouch and are carried there for seven weeks. After this there is little parental care, a trait that enables adult bandicoots to mate and reproduce several times a year (3).Top
Golden bandicoot range
This species was once widespread in central Australia. By 1992 it had been lost from most of its mainland range, except for a small area in northwest Kimberly (5). In 2000 a report was published by the National Wildlife and Parks Service revealing that this species was presumed to be extinct on the mainland (6). It remains on Barrow, Middle, and Augustus Islands (5).Top

Golden bandicoot status
This species is classified as Vulnerable (VU B1+2e) on the IUCN Red List 2003 (1).Top
Golden bandicoot threats
This species has been lost from most of its former range (5). It is thought that reasons for this include changes to fire regimes, competition with rabbits and predation from introduced mammals such as the European red fox (Vulpes vulpes) (5).Top
Golden bandicoot conservation
This species occurs and is protected in the Prince Regent Nature Reserve, Kimberley, and in Barrow Island and Middle Island Nature Reserves (5). Islands are recognised as extremely important areas for vulnerable species, especially those species which are threatened on the mainland, such as the golden bandicoot. Recovery Plans have been established to define the causes of this species decline and to address these in the species present range. The eradication of rats (Rattus rattus) from Middle Island is now underway. There are also plans to set up captive breeding colonies, and reintroduce individuals to areas where they were once found (5).Top

This information is awaiting authentication by a species expert, and will be updated as soon as possible. If you are able to help please contact:
- A category used in taxonomy, which is below ‘family’ and above ‘species’. A genus tends to contain species that have characteristics in common. The genus forms the first part of a ‘binomial’ Latin species name; the second part is the specific name.
- A diverse group of mammals characterised by their reproduction. The embryo is born 11-35 days after conception. The tiny newborn crawls into the marsupium (pouch) and attaches to a teat where it stays for a variable amount of time. They also differ from placental mammals in their dentition.
- Active at night.
- Organisms that feed on both plants and animals.
