This post is by Ben, who is not a student in our class, but he was very keen to tell our readers about blue tongue lizards.
Skinks have overlapping scales that are usually smooth and contain small plates of bone. There are more than 300 species of skink in Australia. Most skinks have 4 legs and 3-5 toes but the legless lizard have no legs which means that they have no toes.
Blue tongues are the largest member of the skink family. Blue tongue lizards can live for 20 years in captivity and 5 years longer, that is if they are looked after properly.
DIET: Blue tongue lizards eat carrion, fruit, dog food, egg yolk, baby food, insects, some types of flowers and their favorite are snails.
There are 6 species of blue tongues and here are the 3 most common ones.
- Blotched blue-Tongue
- Eastern blue-tongue
- Shingleback
The Shingleback and blue tongue have a triangular head, but the male’s head are more triangular than the females, that is one of the ways that you can tell if a blue tongue is a male or female. Another way to tell with the Blotched blue-tongue is that the females have more of a blotchy pattern on the back as for the males, their back is more stripy. Blue tongues don’t have as hard scales as Shinglebacks but they are still hard.
If you have a Shingleback or blue tongue in your garden and you have dogs or cats, feed them inside and if you see anything that the dogs or cats will eat near where the lizard lives, get it so the lizard and pets won’t be attracted to it and the pets won’t eat the lizard. Try to keep the pets away from the lizard as much as possible. If you are doing something to your garden, try not to do as much around the where the lizard lives. Before going anywhere, check the driveway to see if there is a lizard and If there is, move it and then go so you don’t run it over.
SHINGLEBACK:
The Shingleback is also called Boggi, Sleepy lizard and Stumpy-tailed lizard. The Shingleback has 1-4 babies after a few months of mating (I’m not quite sure when). Shinglebacks mainly give birth every 2nd year. Shinglebacks and blue tongues mate for life. Once the male finds the female, he will eat by her, sleep under the same bush and walk behind her. If another male comes around the female, the male (female’s mate) will fight with the rival male and might leave scars to the body. Shinglebacks have hard scales so it will be harder for predators do bite or grasp them.
The female Eastern blue-tongue gives birth to round about 10-19 babies 3-5 months after mating. The Blotched Blue Tongue has can have 5-20 babies. The babies like it a bit warmer than the adults for about 6 months. The babies love eating mealworms but they can’t have too many otherwise they will get stomach pains and they can die. If you keep blue tongues, don’t keep the babies in with adults otherwise the adults will trample them or eat them if they get too hungry. If the female lizard are carrying too many babies or get too cold, she will release a form of acid in her uterus were her babies are and they dissolve and the female will use the babies as a food source, this is called aborting.
