The blotched blue-tongue lizard resides in open country with lots of ground cover such as leaf litter and shrubs. At night, they find shelter under the leaf litter, rocks and logs. Because they cannot produce their own body heat, these skinks live in areas where they can bathe in sunlight during periods of the day in the summer. They need to maintain a body temperature of 30 - 35 degrees Celsius when active (Shea 1997).
Because of the great degree of human activity in New South Wales (e.g. the city of Sydney) and Tasmania, blue-tongues no longer live exclusively in the wild. Tiliqua nigrolutea have also adapted to suburban life. They can frequently be found in backyards where some will reside for many years. They will bathe in the sun on the lawns and paths while cooling off in the rockeries, pipes and cavities under the house (Jones & Edwards 1998).
Terrestrial Biomes: savanna or grassland
The appearance of the blotched blue - tongued lizard is hinted in its scientific name: Tiliqua nigrolutea. Nigro and lutea mean black and yellow respectively. Indeed, this lizard is usually dark brown or black with yellow, cream or pink blotches on it. Although the blue-tongues are the largest members of the skink family (Scincidae), many of their characteristics differ from that of an average skink. First of all, they have an unusual body shape with a stout torso, short limbs and a thick, short tail. Furthermore, unlike smaller skinks, blue-tongues rarely lose their tails.
There are also differences between the males and females of the species. The males have proportionally bigger head and a more heavyset body. This is due to the shape of the two hemipenes (the male copulatory organs). Females are longer in length ((27-30cm to the males' 25-27cm). Because of this, the females are greater in mass weighing between 350 - 450g while males stay within the 300-350g range. (Cogger 2000, Jones and Edwards 1998).
Range mass: 300 to 450 g.
Average lifespan
Status: captivity: 11.5 years.
The blotched blue-tongued lizard resides in southern parts of the Australian state of New South Wales and a smidgeon of the neighboring state of South Australia. There are several species of blue-tongued lizards in Australia. This one, Tiliqua nigrolutea is restricted to the highland areas between the Victorian border and the Blue Mountains. It also occurs on Tasmania and the islands of the Bass Strait (Jones and Edwards 1998, Shea 1997).
Biogeographic Regions: australian (Native )
Blue tongues are omnivores and eat a great melange of plants and animals. Since these large skinks are not particularly agile, they eat mostly slow-moving animals such as snails and beetles. Their strong jaws are fashioned to crush the shells of their prey. They have a strong liking for strawberries. In captivity, they are given a diet of catfood and soft fruits such as bananas and kiwifruit. (Cogger 2000)
In suburban areas, the blotched blue - tongue feasts on snails, slugs and caterpillars (its usual diet) which will be plentiful in any garden or backyard (Jones & Edwards 1998).
None
Even though Tiliqua nigrolutea survive in suburbs, many urban aspects pose a great danger for them. The blue-tongues that live in the suburbs often eat snails and insects carrying human-applied insecticides. The poison sometimes kills the lizard. Another hazard for urban-dwelling lizards is lawn mowers (Shea 1997).
This species is not considered to be in need of special conservation measures, though a related species, Tiliqua adelaidensis is considered endangered (Cogger 2000).

These blotched blue-tongues like other blue-tongues are solitary animals except during mating season. Males and females emerge from hibernation at different times. The males come out in late September while the females come forth in late October. Mating occurs soon after in the months of November and December. Studies done at the University of Tasmania show that males begin to produce their sperm as early as the previous fall so that only the final stages of sperm production occurs in the spring. It is at this time that males fight aggressively among themselves. Furthermore the actual coital process can be very rough and violent in manner. Afterwards, females carry the scrape marks from the male's biting (Jones and Edwards 1998)
After impregnation, the embryos develop in their mother's oviduct with the help of an exceptionally well-developed placenta. The placenta contains a large yolky egg which supplies the nutrition for the developing young. The clutch size is generally around six. Earlier studies that put the clutch size at 25 have been dismissed because the strain would have been too much on the mother. At birth, the newborns eat the placental membrane. Within a few days, they willl shed their skin for the first time. Subsequently, the young are on their own and disperse soon after. There is virtually no parental care. Even though they are now fully independent, they will not be sexually mature for four to five years. (Shea 1997)
Because of the great toll on female lizards during their pregnancy, they are likely to only reproduce every other year. Males are reproductively active every year (Shea 1997).
Der Schwarzgelbe Blauzungenskink (Tiliqua nigrolutea) ist eine Art aus der Familie der Skinke (Scincidae). Er ist seit dem Pleistozän fossil belegt.
Der Schwarzgelbe Blauzungenskink wird zwischen 35 und 50 Zentimeter lang. Manche Wissenschaftler trennen diese Art in eine Hochland- und in eine Flachlandform. Die Hochlandform ist größer und dunkler gefärbt als die Flachlandform. Sie weist auch eine farbenprächtigere Bänderung auf. Die Farbe der Bänderung kann dabei von blassem rosa über lachsfarben bis hin zu orange reichen. Wenn er bedroht wird, kann er durch den Anus eine stinkende Flüssigkeit abgeben. Er ist auch in der Lage, seinen Schwanz abzuwerfen.
Sein Hauptverbreitungsgebiet umfasst den Südosten Australiens sowie Tasmanien und die Inseln der Bass-Straße. Er bewohnt sowohl Heideland wie auch Wälder von der Ebene bis in höhere Lagen. Er ist aber auch in Siedlungen anzutreffen.
Der Schwarzgelbe Blauzungenskink ist ein Allesfresser. Er ernährt sich von Blättern, Früchten, Insekten und Spinnentieren.
Der Schwarzgelbe Blauzungenskink erwacht Ende September bis Oktober aus seiner Winterstarre. Er ist lebendgebärend. Die Jungtiere kommen von März bis April zur Welt. Die Art kann bis zu 20 Jahre alt werden.

The blotched blue-tongued lizard (Tiliqua nigrolutea), also known as the southern blue-tongued lizard or blotched blue-tongued skink is a blue-tongued skink endemic to south-eastern Australia.
This species is a relatively large member of the skink family (Scincidae) with a robust body and relatively short limbs. Colouration and pattern varies geographically, with two distinct forms recognised by some herpetologists, i.e lowlands and highlands. The lowlands form tends to be shades of grey or brown with paler silvery to tan coloured blotches along the back, that are contrasted by surrounding darker areas. The highlands form is typically darker (often jet black) that provides a strong contrast to much paler cream or more brightly coloured pink, salmon or orange coloured blotches.
They have a fleshy blue tongue that is used to taste the air and scare off potential predators. They tend to rely on camouflage and bluff as their primary means of defence; however, if cornered or molested, they can put on an impressive and effective defensive display. If further molested, it will bite as a last resort and although the bite can be painful due to its powerful jaws, the teeth are blunt and generally do not break the skin. This species is harmless, as are all skinks and inoffensive by nature. They are sometimes kept as pets, as they adapt well to captivity, eating a wide range of readily available foods.
The lizard is about 14 to 20 inches (35 to 50 cm) long, and is found in wet and dry sclerophyll forests, montane woodlands and coastal heathlands. It is an omnivore with a diet consisting of a variety of insects, snails, carrion, wildflowers, native fruits and other vegetation like select leaves, and occasionally small vertebrates like mice or other young rodents if given the chance. The tail can be dropped (autotomy) when grasped by a predator (like most skinks), but this large skink is much less likely to do so than most other members of the skink family.
The species occurs in Victoria, Tasmania, South Australia, New South Wales, and the Australian Capital Territory.[1] The lowlands form is found in Tasmania and lower altitudes of Victoria right down to the coast. The highlands form is restricted to higher altitudes in NSW and the high country of Victoria. The blotched blue-tongued lizard usually emerges from brumation in early spring, which is the mating season. These large skinks are viviparous (give birth to live young), with the highland/alpine form giving birth to relatively larger and fewer young (about five) compared to the lowland form (about 11). The young are usually born in autumn, after a relatively long gestation period.[2] They are also relatively long-lived (reliably reported up to 30 years in captivity) compared to many of the smaller skink species. They have adapted well to some rural and urban areas, where they can be found living on farms and in gardens where they are an asset, as they eat pests such as snails, slugs, and occasionally rodents.
The blotched blue-tongued lizard is among the animals identified from the Pleistocene fossil sites of the Naracoorte Caves National Park.

Tiliqua nigrolutea est une espèce de sauriens de la famille des Scincidae[1].
Cette espèce est endémique d'Australie. Elle se rencontre en Australie-Méridionale, en Nouvelle-Galles du Sud, au Victoria et en Tasmanie[1].
Ce Tiliqua mesurant de 45 à 50 cm ressemble beaucoup à Tiliqua scincoides. Néanmoins, on remarque que les écailles du crâne sont plus marquées, la queue plus courte. La forme dite alpine, est celle qui a donné son nom scientifique à l'espèce. En effet, cette dernière est noire marbré de orange pâle à rouge sur le dos, formant des tâches lui valant le nom de "blotched" en anglais. Son ventre et tout la partie inférieure de la machoire est jaune. Nigrolutea signifiant, noir et jaune.
La forme de plaines, dite "lowlands", est plus claire, jaune pâle a grise, avec un dos brun à gris foncé, les tâches du dos sont de même couleur que le ventre.
Cependant il existe d'autres variations de couleur, certains étant même bleutés dans les petites Îles du nord de la Tasmanie.
Ce Tiliqua habite aussi bien les plaines que les zones montagneuses. La forme alpine reste active même quand les températures chutent à 4 °C. Par températures fraiches, l'espèce cherche des coins pour s'exposer au soleil quelques heures, là ou ses cousins hivernent pour endurer le froid. Durant les saisons les plus froides, l'espèce hiverne elle aussi. Tout comme l'espèce cousine Tiliqua scincoides, l'espèce est omnivore et opportuniste, mangeant aussi bien des gastérodopodes, que des mammifères et oiseaux, tout en passant par de la végétation et divers cadavres. L'espèce est si opportuniste qu'on la trouve dans les jardins à se nourrir dans les gamelles des animaux.
Selon les températures et distribution, l'espèce passe 3 à 4 mois à hiverner. Selon la répartition, les individus vont commencer à chercher un partenaire à la sortie de l'hiver, ou une fois l'hiver passé. Après 3 à 4 mois de gestation en moyenne, la femelle donne naissance à une portée formée, qui dès la naissance s'alimentera comme les adultes.
La lucertola chiazzata dalla lingua blu (Tiliqua nigrolutea Quoy & Gaimard, 1824) è un rettile della famiglia degli scinchi.
Lunga circa 35 cm, ha gli occhi con palpebre pesanti, ben protetti. Può secernere un muschio dall'odore pessimo. È vivipara e assai longeva (sino a 20 anni di vita)
Vive nelle foreste ed è onnivora, infatti la sua dieta consiste di foglie, fiori, invertebrati striscianti e piccoli vertebrati. Cade in letargo e ne esce in settembre avanzato (almeno in Tasmania), si accoppia a fine ottobre e i piccoli nascono in autunno (marzo-aprile).
Si possono trovare in Tasmania e nella parte sud orientale dell'Australia. È una specie molto antica: è stata identificata tra i fossili del Pleistocene di Naracoorte.
