Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Mammalia
Order: Peramelemorphia
Family: Peramelidae
Subfamily: Peramelinae
Genus: Perameles
Species: Perameles nasuta

Geographic Range

East coast of Australia

Biogeographic Regions:
australian (native ).

Habitat

Found in rainforest, wet and dry woodlands, and sometimes in more open areas with little ground cover.

Terrestrial Biomes:
forest ; rainforest .

Physical Description

Mass
850 to 1100 g; avg. 975 g
(29.92 to 38.72 oz; avg. 34.32 oz)


Basal Metabolic Rate


Head and body length 310-425 mm; tail length 120-155 mm.

Both the muzzle and ears are long and pointed. Fur is grayish brown on the dorsal side, and creamy on the ventral side. The forefeet and the top of the hindfeet are also creamy white. The tail is hairy. Unlike some other bandicoots, there is little or no barring on the rump. The pouch of bandicoots opens towards the rear of the mother. In bandicoots, the second and third toes on the hindfeet are syndactylous (joined), and the fourth toe is the main toe on the foot. The joined second and third toes are used in grooming. (Nowak, 1991; Strahan, 1995)

Some key physical features:
endothermic ; bilateral symmetry .

Reproduction

The gestation period of the long-nosed bandicoot is quite short, about 12.5 days. There can be 1-5 young in a litter, with the usual number being 2 or 3. Bandicoots have a placental structure (but it lacks the villae in the placenta of placental mammals), and the young remain attached to this by umbilical cords for some time after birth, until the young begin suckling on teats in the pouch. Young are weaned at about 60 days, and the mother may have the next litter only a few days after the previous one is weaned. (Nowak, 1991; Strahan, 1995).

Key reproductive features:
gonochoric/gonochoristic/dioecious (sexes separate); sexual .

Behavior

Perameles nasuta is solitary and mainly nocturnal. During the day, these animals usually stay in their nests, which are shallow holes holes in the ground that are lined with grasses and other plant material. When foraging, P. nasuta digs conical holes with its forefeet. It feeds by inserting its snout into these holes and searching for food. At night, the long-nosed bandicoot can be quite active, often traveling at a running pace. (Nowak, 1991; Strahan, 1995)

Key behaviors:
motile .

Food Habits

Perameles nasuta is mainly insectivorous, although it also eats some plant material, and will occasionally eat worms, mice, and lizards. (Nowak, 1991; Strahan, 1995).

Economic Importance for Humans: Negative

The long-nosed bandicoot will burrow in lawns, gardens, and agricultural fields, and so is considered by some to be a pest.

(Nowak, 1991)

Conservation Status

IUCN Red List: [link]:
Lower Risk - Least Concern.

US Federal List: [link]:
No special status.

CITES: [link]:
No special status.

Perameles nasuta is relatively common within its range, particularly in coastal woodlands. (Nowak, 1991; Strahan, 1995).
