In the world's hottest deserts, amazing creatures called desert dragons make their home. These small lizards live in places where temperatures can reach 45 degrees Celsius during the day. Despite the harsh conditions, they have found clever ways to survive. Desert dragons spend most of their time looking for food and hiding from the strong sun. They live in many desert areas across Africa and Australia, moving carefully between rocks. Desert dragons have special features that help them live in the desert. Their thick scales protect their skin from the burning sand and hot sun. They have special eyelids that keep sand out of their eyes. Their wide feet help them walk on hot sand without getting hurt. Most importantly, their nostrils can close to stop sand from getting in when they breathe. The scales on their body are very hard and reflect sunlight well. These remarkable animals are most active during the early morning and late evening when it's cooler. During the hottest part of the day, they dig holes in the sand to stay cool. They eat small insects and plants that they find in the desert. When danger comes, they can run very fast across the sand to escape from birds and other predators. They use their excellent eyesight to spot tiny insects moving in the sand. Desert dragons show us how animals can adapt to live in difficult places. They sleep during the day and wake up when it's cool. Their bodies are perfect for desert life, and they know exactly when to be active or rest. These amazing lizards prove that life can survive even in Earth's harshest places. Scientists study these special creatures to learn about surviving in extreme temperatures.
