The class is then broken into several orders and the lizards belong to the order called Squamata . Snakes and amphibians also belong to this order. The majority of lizards then fall into the suborder called Lacertilia . This is where we start with our table below. The suborders are broken into families .
Most families are groups of varied lizards tied together by anatomical similarities.
Each genus contains one or more species , the species being the individual animal. Many, though not all, of the more common species are listed in the right hand column of this table. Geckos are found worldwide in all the warmer regions. What distinguishes them as a family is that they have the ability to produce sounds. Some make high pitched calls, some sound like ducks, and others like barking dogs.
