Blue-tongue lizards love to bake in the sun during the summer months and it’s likely you’ll bump into one on your wanderings. We studied the lizard in Week 2 of the Australian Nature Study Guide and one thing I found interesting, was that they give birth to their young, unlike most lizards which lay eggs.
Another interesting fact, was the third eye which sits on top of the lizards head. This eye is able to detect night from day and it helps to regulate their body temperature. The most fascinating thing about these lizards is, of course, their blue tongue which they stick out while flattening their bodies when they feel threatened.
They are great backyard buddies as they keep insects, snails and slugs in check by the veggie patch.

Look out for a Blue-Tongue Lizard or any skink on your nature ramble. Should you find one, observe it carefully. Can you spot the third eye? Do you notice how the scales lay neatly one on top of the other? This is to keep the dirt out. Take note of it’s habitat and time of day. What was it doing? Can you estimate it’s length?
Sketch your sighting in a nature journal. It can be a simple drawing of the lizard within it’s habitat or you can make a scientific sketch and label it’s anatomy. Older students can draw the internal anatomy of the lizard if they’d like to be challenged. You can add facts you’ve leaned about the lizard or journal your own observations.
