Feeling sharp today. World Lizard Day

From mythology to modern media, lizards have often been portrayed as scary reptiles. As it turns out, they're not as dangerous as stories might lead you to believe. Today, World Lizard Day, is the perfect time to learn about these cold-blooded creatures. With more than 7,000 species, these animals have adapted to a wide range of environments—from deserts to rainforests. Take the gecko, for example. These little climbers have specialised toe pads that let them scale walls and even walk on ceilings. Then there's the chameleon, known for its colour-changing skin. While many think it's all about blending in, chameleons also change colour to communicate and regulate their temperature.

Now let's focus on the peculiar creature in today's image that's trekking across the arid landscape in Australia's Watarrka National Park. Its pace is deliberate, its skin a maze of spiky armour. Meet the thorny devil, also known as the thorny dragon or Moloch. With clever hydrophilic skin that channels moisture to its mouth, this reptile can hydrate just from the dew on its body. It can thrive in extreme desert conditions that would be inhospitable to many. So, the next time you spot a lizard, take a moment to appreciate these cool, scaly wonders of the animal kingdom.
