This lovely gecko photo was taken by Dan Tombs. Geckos are small to average size lizards that are found in warm climates all over the world. There are 1,196 different species of geckos! They make chirping sounds to communicate. Some people keep geckos as pets. Many geckos have toe pads that allow them to climb smooth surfaces such as walls and even allow them to cross a ceiling. House geckos are valued as they eat insects.
