Peramelemorphia: bandicoots, bilbies and related marsupials

Characteristics

• Body form: compact, with long snout, large ears in some species (notably bilbies), and hind limbs suited for rapid movement.
• Diet: omnivorous—earthworms, insects, seeds, fruit and small vertebrates are typical food items.
• Behavior: many are nocturnal or crepuscular and use burrows or shelters to rest during the day.

Peramelemorphs are adapted for digging: strong claws and muscular forelimbs let them forage for invertebrates and roots. Reproductive biology is marked by a brief pregnancy and development of underdeveloped young in the maternal pouch.

Taxonomy, history and conservation

The order contains several families, including living groups that account for most modern species and a few extinct lineages known from subfossil and fossil remains. European naturalists first described many species in the 18th and 19th centuries; since then, taxonomy has been refined using anatomy and genetic data.

Many peramelemorphs have declined because of habitat loss, introduced predators (cats and foxes), and altered fire regimes. Some bilby species and several bandicoots are the focus of active conservation: captive breeding, predator control and habitat restoration. Notable conservation programs aim to maintain ecological roles these animals play as soil-turners and insect controllers.

Notable facts

• Bilbies are often highlighted in Australian conservation as emblematic of threatened native fauna.
• Several species have become locally extinct since European settlement; others persist in protected reserves and islands.
