Blue-tongued skinks and Australian/Pacific skinks

Applies to most species in this group. Habitat: Woodland, grassland and rainforest. Individual species can differ, so compare with the species numbers above and the linked sources.

Housing & setup

  • For Tiliqua, current ReptiFiles guidance calls for at least 12 ft² of floor area; this does not specify arboreal Corucia housing.
  • Deep substrate, a basking spot and UVB.

Climate & lighting

Starting point only: Tiliqua moisture requirements differ by species and subspecies; the 40–60% default excludes Indonesian and arid forms. Check the species-specific values for this animal where shown.

Basking spot95–105°F
Warm side / daytime82–88°F
Cool side72–78°F
Humidity40–60%
  • UVB: Recommended.

Sources 11311466206207

Diet

  • Blue-tongues: omnivorous mix of lean protein, greens and vegetables. Solomon Islands skinks: strictly leafy greens and vegetables.

Sources 11311466206207

Social life

  • Tiliqua should be housed individually; do not extrapolate that recommendation to every genus in this guide.

Sources 11311466206207

Health watch

  • Obesity and retained shed; Indonesian species need more humidity than Australian ones.

Understanding the animal

About this animal

About this animal

Three of its four recognised subspecies are found in Western Australia, where the bobtail name is most frequently used. The fourth subspecies, T. rugosa asper, is the only one native to eastern Australia, where it goes by the common name of the eastern shingleback.

OverviewTiliqua rugosa, most commonly known as the shingleback skink, shingleback lizard, bobtail lizard, and the two-headed skink (often simply shingleback or bobtail); is a short-tailed, slow-moving species of blue-tongued skink (genus Tiliqua) endemic to Australia. Three of its four recognised subspecies are found in Western Australia, where the bobtail name is most frequently used. The fourth subspecies, T. rugosa asper, is the only one native to eastern Australia, where it goes by the common name of the eastern shingleback. — Wikipedia (community-edited)
Where it livesTrachydosaurus rugosus inhabit semiarid plains and woodlands that typically have a harsh, dry summer and fall, followed by a cool winter and spring with increased precipitation and resources. — Animal Diversity Web
Wild dietThe shingle back is an omnivore that would be considered an opportunistic feeder. — Animal Diversity Web
BehaviorTrachydosaurus rugosus are colonial in nature, and are therefore not aggressive towards one another. — Animal Diversity Web
ReproductionTrachydosaurus rugosus are viviparous, typically producing 1 to 2 young, although triplets do occasionaly occur. — Animal Diversity Web
LifespanThe shingle back skink has an average life span of about 10 to 15 years, although there is a living and healthy specimen which resides as a captive in England (his name is Stumpy), that is an amazing 35 years old! — Animal Diversity Web
Appearance and sizeShingle back skinks are among the largest of the Australian skinks. — Animal Diversity Web
History and namingThe shingleback skink has become a popular pet among Australian enthusiasts. They are relatively docile and easy to feed and maintain. A permit may be required to keep them in some states. — Wikipedia (community-edited)
ConservationTrachydosaurus rugosus are quite common in Australia and do not suffer from many natural predators. — Animal Diversity Web
Native climate (measured)

Native climate (measured)

Warm-season highsabout 85°F (up to 92°F in the hottest sampled areas)
Cool-season lowsabout 43°F (down to 37°F in the coldest sampled areas)
Average temperature56–66°F across sampled records
Relative humidity59–67% on average (driest month about 51%)
Rainfallabout 598 mm a year

Measured at 129 wild occurrence records sampled against WorldClim 2.1 climate data (1970–2000 averages). Air conditions in the range are ecological context, not enclosure settings: microhabitats such as burrows, leaf litter or basking rocks can be cooler, warmer or more humid.

Data and studies

Researched care notes

Findings checked against veterinary, zoo, welfare, keeper and peer-reviewed sources. Air, basking-surface and water temperatures are kept separate, and where sources disagree both are shown. “Study” notes report what a paper measured, not a universal rule.

Blue-Tongued Skink

Researched for this genus; applies to its species unless a species note says otherwise.

  • Surface: ReptiFiles distinguishes a general basking surface of 37–40°C from 40–46°C for Tiliqua scincoides; these are localized surface recommendations, not whole-enclosure air settings.1
  • Air / night: the guide gives Australian species approximately 18–24°C and Indonesian species 21–24°C; apply the identified species' requirements rather than merging them.1
  • Humidity / taxon difference: Northern and Eastern T. scincoides receive 40–60% RH guidance, versus 60–80% for Indonesian T. gigas; uncertain identification prevents choosing a single genus-wide value.1
  • Study: eleven adult T. scincoides showed increased plasma 25-hydroxyvitamin D after four weeks of either two or twelve hours of daily UVB exposure.2
  • Study limit: this UVB experiment measured a biochemical response under one diet; it does not establish a universal safe lamp distance, UV Index, or supplementation dose for every Tiliqua species.2
  • House individually; ReptiFiles warns that territorial disputes can seriously injure co-housed skinks of either sex.3
  • Provide substantial horizontal movement space plus sufficient height for furnishings and safely installed lighting; cage footprint alone does not describe the usable setup.3
  • Feed a varied omnivorous ration containing suitable plant and animal foods; younger skinks need a different balance from adults.4
  • Prepare firm vegetables in finely chopped, shredded or mashable form so they are easier to consume.4
