Description

This is a large species of terrestrial blue tongue measuring upwards of 60 centimetres in length and over 1 kilogram in mass. It has a stout body and short legs. [2] It is variable in color but generally has a banded pattern. The tongue is blue-violet [4] to cobalt blue in color. [5] The tongue is used, like most animals in the order Squamata, to collect micro molecules to deliver to sensory organs as a "smell" sense using the tip. The tongue of the blue-tongued skink is also useful in catching prey, as it is coated in a sticky mucus to preserve surface tension in motion to draw an insect back into the mouth. [6] Due to its characteristic blue tongue and its curious nature, it is a popular companion animal in Western countries. [7]

This lizard is diurnal, active during the day. It is omnivorous, feeding on insects, snails, frogs, other reptiles, small birds, small mammals, carrion, some plant material, fruits, and other vegetation. [2] [8] [9] It is ovoviviparous, and a live bearing reptile. The female's litter can have a range from 5 to 25 live young per litter with Tiliqua scincoides scincoides being known to carry the largest litters. [4] This species is known to live over 30 years. It is an adaptable animal, often finding habitat in urban and suburban areas, including residential areas of Sydney. [2] The lizard is considered beneficial in these areas, with its appetite for garden pests such as slugs and snails. [4]

When threatened it may hiss and reveal its blue tongue, startling potential predators. [4]

There are many localities and established color variations for each. Eastern blue tongues can have a green or yellow phase, they can have eye bands or not, and look different coming from the Brisbane area and others. In captivity, breeders have expressed albinism and hyper melanism. Northerns are either classic/standard looking or speckled from the Kimberly region and Prince Regent National Park. In captivity, breeders have expressed exaggerated colorations that can be red, yellow, orange, caramel, white, and others. Tanimbar blue tongues are the most glossy and often seen in a gold or silver phase. Tanimbar and Kimberly Northerns are known for being more aggressive in the wild than other species. All blue tongue species display greater tolerance for human interaction the more generations they are bred in captivity.

Skinks are lizards belonging to the family Scincidae, a family in the infraorder Scincomorpha. With more than 1,500 described species across 100 different taxonomic genera, the family Scincidae is one of the most diverse families of lizards. Skinks are characterized by their smaller legs in comparison to typical lizards and are found in different habitats except arctic and subarctic regions.

<span class="mw-page-title-main">Pink-tongued skink</span> Species of lizard

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. In addition, their blue tongue will produce a response in the prey which will in turn diminish the attack. 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.

<i>Tiliqua rugosa</i> Species of lizard

Tiliqua rugosa, most commonly known as the shingleback skink or bobtail lizard, is a short-tailed, slow-moving species of blue-tongued skink endemic to Australia. It is commonly known as the shingleback or sleepy lizard. 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.

<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.

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.
