The Centralian blue-tongued skink or Centralian blue-tongue (Tiliqua multifasciata) is a species of skink, [2] occurring predominantly in the far north-west corner of New South Wales, Australia. [3] It is one of six species belonging to the genus Tiliqua ; the blue-tongued skinks and the shinglebacks.

Contents

Description

The Centralian blue-tongue is of a very robust build, short body and slender tail, and is among the largest 1% of species in the family Scincidae. [4] Both the forelimb and hindlimb have five digits. [3]

Colouring

The skink is predominantly pale brown to grey in colour with a series of nine or more orange-brown bands along the length of the body and tail. These darker coloured bands are much wider than the paler grey-brown interspaces but are at their narrowest along the mid-dorsal region of the skink. [5] There is a distinguishing black stripe surrounding the eye and extending to just above the ear, and upper-hind areas of limbs are also black. [3] [5] [6] The skink is pale cream to white on the underside. [3] [5]

Distribution

The geographical distribution of the blue-tongued skink lies throughout the far north-west corner of New South Wales and South Australia, and centrally throughout Western Australia, the Northern Territory and Queensland. [5] [6] In general, habitats include a variety of arid and semi-arid stony and red sandy spinifex vegetated areas. [6]

Behaviour

Like many other reptilian species, the blue-tongued is a fairly sedentary terrestrial creature. [7] It is a ground-dwelling, diurnal species [5] and displacements are relatively short (less than 20 metres) and on average the total distance travelled each day can fall between 122 and 245 metres. [7]

Diet

Analyses of stomach contents have shown that the blue-tongue feeds on a combination of seeds, insects, livestock dung and some vertebrate and invertebrate material such as that of bird or other reptilian remains (i.e. fragments of bone, loose feathers). [4]

Reproduction

Along with the other five species of the same genus, the Centralian blue-tongued skink is a viviparous species – it bears between two and 10 live young in a single litter. [3] [5] [6]

Threats

The geographical location of the skink sees one of its major threats to be ingestion of the invasive and toxic cane toad, [8] but it is also under pressures from other anthropogenic processes such as fire and habitat fragmentation. [7] However, the species is still currently listed as least concern. [1]

<span class="mw-page-title-main">Skink</span> Family of reptiles

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. It 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 or panana in Indonesia. 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.

<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 native to Australia

The Tiliqua scincoides scincoides, or eastern blue-tongued lizard, is native to Australia. Its blue tongue 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.

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.

The black rock skink is a species of large skink native to Eastern and Southern Australia from central New South Wales to Grampians National Park in Victoria. A large, dark colored skink, up to 135 mm from snout to base of the tail, the black rock skink is the first reptile discovered to have a "nuclear family" structure where the parents form a pair and care for their offspring for more than one year. The black rock skink is a viviparous skink meaning females give birth to live offspring instead of laying eggs. They defend their home range and families against conspecifics for up to several years.

Crocosaurus Cove is a crocodile herpetarium and aquarium zoo located in an indoor complex in the city district of Darwin, Northern Territory, Australia. Its main focus as the facility's name indicates is the tourism drawcard of the crocodiles of northern Australia. The park has a considerable number of saltwater crocodiles including 700kg and 5.1 metre long male Burt, who appeared in 1986 movie Crocodile Dundee and made news in 2018 for 'psychic predictions' outcomes of the 2018 Soccer World Cup by reaching up and grabbing photographs of players which was seen as match and player performance 'predicting'. The facility has also had success with breeding and hatching baby crocodiles including in July 2022 with baby crocodiles hatched to parent crocodiles female Kate and male William. One of the things most well known at the facility which significantly increased visitor numbers is a 'cage of death' experience where paying visitors can swim in water with large crocodiles while protected from physical contact with them by being enclosed behind a glass safety dome. As previously mentioned a significant number of other native Australian reptiles are also kept at the facility and publicly exhibited. Mick Burns the owner is also owner of Darwin Crocodile Farm.

The Spinifex slender blue-tongue or Samphire slender bluetongue is an endemic species of skink that inhabits the arid areas of central Australia. The Spinifex slender blue-tongue is closely related to the large blue-tongue skinks. However is individually categorised under the Genus Cyclodomorphus and species Cyclodomorphus melanops(C. melanops).
