Have you ever seen a gecko? They are harmless lizards that live all over the world. They grow to be about ten inches long with half the length in the tail. Geckos eat insects, fruit, and flower nectar. And that long tail, it has several purposes, one of which is to store food. It also helps with balancing when the gecko climbs trees. Like other lizards a gecko can lose its tail to escape danger. When threatened geckos will make chirping noises. Most geckos are nocturnal which means they are active at night. Finally, a gecko has eyelids that they can wash with their tongue!
