Taxonomy Physical Characteristics

Kingdom: Animalia

Phylum: Chordata

Class: Mammalia — mammals

Order: Diprotodontia — koala, wombats, possums and gliders, kangaroos, wallabies

Family: Petauridae — lesser gliders, striped possum, Leadbeater’s possum

Genus: Petaurus — lesser gliders

Species: Petaurus breviceps* — sugar glider

Subspecies:
P. b. breviceps
P. b. ariel
P. b. longicaudatus
P. b. papuanus

*Note: May be several species. Additional research needed.

Body Weight
60-150 g (2-5.3 oz)

Head-body Length
115-210 mm (4.52-8.3 in)

Tail Length
150-210 mm (5.9-8.3 in)

Pelage
Fur fine and silky; aids gliding. Coloration variable throughout range: upperparts gray, underparts pale cream to medium gray, tail dark gray.

Distribution & Status Behavior & Ecology

Range
Australia (including Tasmania), New Guinea and neighboring islands. Most widespread marsupial in Australasia.

Habitat
Various kinds of forests: mature forest, young-growth forest, fragmented/degraded forests, and plantations and rural gardens. Require tree hollows for nesting and breeding.

IUCN Status
Least Concern (2016 assessment)

CITES Appendix
Not listed

Other Designations
Protected in Australia and Tasmania

Populations in the Wild
No scientific studies. Considered common. Populations considered stable.

Locomotion
Strong climbers. Skin membrane between front and hind limbs allows gliding from tree to tree. Capable of making tight turns, mid-air.

Activity Cycle
Forage at night. Rest during the day in nest in tree hollow. When food is scarce or nights are cold, use torpor to conserve energy.

Social Groups
Nest in groups. Commonly 2 to 7 adults and their young (up to 10 to 12 individuals in total). Territory maintained by 1 or 2 dominant males.

Diet
Plant sap and gum, nectar, pollen, manna. Insects, their larvae, and the secreted substances (lerp, honeydew) of sap-sucking insects; spiders; small birds.

Predators
Owls, kookaburras, pythons, goanna lizards, feral cats, house cats. Possibly foxes.

Reproduction & Development Species Highlights

Sexual Maturity
Approximately 12 to 18 months

Mating System
Often polygynous (males mate with multiple females); monogamy observed where food is very limited.

Gestation
15 to 17 days

Litter Size
Typically 2 young. Less commonly, 1 or 3 young.

Interbirth Interval
Females breed each year. Produce 1 to 2 litters per year.

Birth Weight
Not well documented. In one study, 0.19 g (0.0067 oz).

Longevity
In the wild: Typically 4 to 5 years. Maximum 9 years.
In managed care: Long-lived; 17 years maximum.

Feature Facts

  • One of the smallest marsupial gliders
  • Common name refers to this animal’s preference for sweet foods
  • Flexible skin membrane between wrist and ankle for gliding
  • Fur texture increases lift and aids gliding
  • Carry nesting material in semi-prehensile tail
  • Sharp lower teeth for biting into tree bark and territory defense
  • Each social group has a distinctive scent that helps members recognize one another; fiercely defend territories
  • Thought to be an important pollinator of native plants
  • In Tasmania, sugar gliders prey heavily on birds, some of which are endangered species
  • Popular pet in the United States and Japan

Acknowledgments

Many thanks to Dr. Ross Goldingay for providing expert content review of this fact sheet.

Dr. Goldingay, Associate Professor in the School of Environment, Science, and Engineering at Southern Cross University, Lismore, is a wildlife ecologist who has extensively studied the biology of gliding mammals. In his early research, he conducted experiments that revealed sugar gliders to be important pollinators. He has also conducted research on glider habitat use, population ecology and genetics, communication, parental care, physiology, and locomotion.

Much of Dr. Goldingay’s research relates to the protection of threated species. He has conducted numerous studies to assess the impacts of habitat loss on wildlife behavior and population health. He has led longer-term studies to evaluate whether gliders use artificial nest boxes (as substitute tree hollows), as well as whether the installation of wooden poles and rope bridges enables gliders to safely cross roads. To learn more about Dr. Goldingay, view his research profile and publications.

In addition to teaching and research, Dr. Goldingay is editor of Australian Mammalogy, the journal of the Australian Mammal Society.
