The Indonesian blue-tongued skink (Tiliqua gigas) is a lizard in the family Scincidae. It is a close relative of the Eastern blue-tongued lizard. They are endemic to the island of New Guinea and other various surrounding islands. They are found typically in the rainforest, and in captivity, require high humidity. As opposed to Tiliqua scincoides, they are fairly lean. They're also accompanied by long tails (60–90% of their snout-vent length).



Tiliqua gigas has an elongated body and very small limbs, which is typical of most skinks of the genus. They typically get up to 18-24 inches (46-61 centimeters) in length and weigh up to 1 kilogram. They are known for their thinner, elongated tails, and avoiding participation in seasonal brumation as they regulate their breeding cycle on a wet and dry season.

T. gigas gigas are the most tropical and known for having the skinniest tail. They have solid, dark, or near solid dark limbs. T. gigas evanescens are easily recognized for having slightly more colored speckling on their limbs, a single, centered stripe on the back of their neck, and not always but most often, having very thin body banding. They also have the longest tail. Tiliqua gigas keyenesis is known for is all-over body speckling, including speckling all over the face.

The Australian Northern Blue Tongue (Tiliqua scincoides intermedia) is recognized as the largest of all the species and subspecies. Not enough studies have been conducted to give that title to either of the Tiliqua gigas species. What is irrefutable, is the Tiliqua gigas evanescens species is the longest of all the blue tongues often reaching lengths that exceed 30 inches from snout to tip of tail.


There are currently three subspecies of Tiliqua gigas, and many localities within each subspecies. First subspecies to be recognized is Tiliqua gigas gigas (Schneider, 1801), in which there are the most and newest recognized localities including: Halmahera, Classic Indonesian, Sorong, Aru, Jayapura, Manokwari, and Ambon. The second subspecies is Tiliqua gigas keyensis (Oudemans, 1894), typically called the Kei island blue-tongued skink. Lastly, there is Tiliqua gigas evanescens , which is called the Merauke blue-tongued skink.

The pink-tongued skink is a species of lizard in the family Scincidae. C. gerrardii is endemic to Australia, where it is also called commonly the pink-tongued lizard. As suggested by these common names, its distinguishing characteristic is a pink tongue as opposed to the blue tongue of lizards of the closely related genus Tiliqua.

<span class="mw-page-title-main">Blue-tongued skink</span> Genus of lizards

Blue-tongued skinks comprise the Australasian genus Tiliqua, which contains some of the largest members of the skink family (Scincidae). They are commonly called blue-tongued lizards or simply blue-tongues or blueys in Australia. As suggested by these common names, a prominent characteristic of the genus is a large blue tongue that can be bared as bluff-warning to potential enemies. The type of predator/threat that is near will determine the intensity of colour present in the tongue. The tongue can also deform itself and produce a thick mucus in order to catch prey. They are relatively shy in comparison with other lizards, and also significantly slower due to their shorter legs.

<span class="mw-page-title-main">Eastern blue-tongued lizard</span> Species of reptile

The Tiliqua scincoides scincoides, or eastern blue-tongued lizard, is native to Australia. It is unique due to its blue tongue, which can be used to warn off predators. In addition to flashing its blue tongue, the skink hisses and puffs up its chest to assert dominance and appear bigger when in the presence of its predators such as large snakes and birds. The eastern blue tongue is ovoviviparous and precocial, meaning that its young are more developed and advanced at their time of birth. The Tiliqua scincoides scincoides is not venomous to humans and can be found in suburban and urban areas, specifically in house gardens.

<span class="mw-page-title-main">Stokes's skink</span> Species of lizard

Egernia stokesii is a gregarious species of lizard of the Scincidae family. This diurnal species is endemic to Australia, and is also known as the Gidgee skink, spiny-tailed skink, Stokes's skink and Stokes's egernia. The species forms stable, long-term social aggregations, much like the social groups seen in mammalian and avian species. This characteristic is rarely found in the Squamata order, but is widespread within the Australian subfamily of Egerniinae skinks. Populations of E. stokesii are widely distributed, but fragmented, and occur in semi-arid environments. There are three recognised subspecies. The conservation status for the species is listed as least concern, however, one subspecies is listed as endangered.
