The Black Yellow Blauzungenskink ( Tiliqua nigrolutea ) is a kind from the family of skinks (Scincidae). It has been fossilized since the Pleistocene .
description
The black and yellow blue-tongue skink becomes between 35 and 50 centimeters long. Some scientists separate this species into a highland and a flatland form. The highland form is larger and darker in color than the flatland form. It also has more colorful banding. The color of the banding can range from pale pink to salmon-colored to orange. If threatened, it can release a smelly liquid through the anus. He is also able to shed his tail.
distribution and habitat
Its main distribution area includes southeast Australia as well as Tasmania and the islands of the Bass Strait . He inhabits both heathland and forests from the plains to higher altitudes. But it can also be found in settlements.
nutrition
The black and yellow blue tongue skink is omnivorous . It feeds on leaves, fruits, insects and arachnids .
Reproduction
The black and yellow blue-tongue skink awakens from its winter rigor at the end of September to October. He is viviparous . The young are born from March to April. The species can live up to 20 years.
