The gecko family, whose scientific name is Gekkonidae, belongs to the order Squamata and the superorder Lepidosauria. Geckos are reptiles. The primary home of geckos is in tropical areas, but some species are also found in very dry and rocky areas. Since the gecko family has been around for millions of years - about fifty million years to be exact! - it has spread over a large area of the world and adapted well to the conditions in different areas. The family includes 55 genera and even more than one thousand different gecko species! Many species have probably not even been discovered yet. The species and genera sometimes differ considerably and - depending on the area of distribution - have sometimes evolved quite differently. Not all of the more than a thousand species are kept as pets. In a domestic terrarium, for example, the genus of leopard geckos, the genus of day geckos, the crested gecko species or the tokay species are quite common.
