Blue Tongue Skink
Northern Blue Tongued Skink
Blue-tongued skinks are spread across the mainland Australia. Few subspecies are also found in parts of Tasmania, New Guinea, and some Indonesian islands.
Habitat: Where do Blue-tongued Skinks live
They are spread mainly across the humid areas since these reptiles need moisture. They are found in open woodlands, grasslands, rainforests, at the margins of forest and field, and semi-deserts. Some are, however, found in the desert regions and are adapted to a harsh lifestyle.

Behavior and Lifestyle
This Australian lizard is a gentle-natured, solitary, shy reptile that would spend its day basking and eating. They are mostly diurnal (active during day time). At night, they rest taking shelter in the wild. They spend most of the time during winter months inside holes and burrows and would only come out for basking in the sun.
However, if they feel threatened, they would turn back at the threat and try to scare it off opening their big mouth and sticking out the tongue. It would also puff up its body and hiss.
If mishandled or even attacked by the tail, some species of the blue-tongued skinks have the ability to break or pull off their tails on their own as a defense mechanism (though not as quickly as the geckos or the other skink species). A new tail emerges out from its place, but will not look like the original. However, some species of blue-tongued skinks (like the Tiliqua rugosa) do not have the ability to drop their tails at all.

Diet: What Do Blue-tongued Skinks Eat
The blue-tongues are omnivores, i.e. they eat both plants and other animals. They would mostly prefer to eat snails, worms, slugs, caterpillars, crickets, small insects, rotting meat, flowers, fruits and berries.
Mating and Reproduction
These lizards would normally spend a solitary life. However, the males would move out for its mate anytime between the months of September and November. The mating is not a complex process though but often ends roughly with the female getting bruises from the male’s teeth. The female gives birth after about 14 weeks.

Life Cycle of the Baby Blue-tongued Skink
At a time, the female gives birth to 10-25 live youngs. The eggs do not have any hard shell. The young ones hatch from soft-shelled eggs inside the female. The females carry their eggs internally which it hatches just prior to the young ones leave the female’s body. The babies, when born, are about 4 inches by size and grow very quickly if they get enough food.
- Blue-tongued skinks have strong jaws that they can use to crush snail shells and beetles.
- Skinks have heavy tails and very short or missing limbs. This is an adaptation to enhance their ground-dwelling and burrowing lifestyle.
- These reptiles, like geckos, can drop their tail, to escape from enemies.
- The bizarre color contrast of the bright blue tongue with the large pink mouth cavity is enough to scare off many of its enemies.
The potential predators of these reptiles are mostly dogs and cats that would eat them. Also, predatory birds like the Brown Falcons and Laughing Kookaburras, large snakes like the Red-bellied Black Snake, Eastern Brown Snake, and Mulga Snake are their main enemies.
