Anuran taxonomy is rather chaotic at times. There are often disagreements as to the legitimacy of certain taxon, from subspecies level all the way up to the family level. In addition, new species are discovered quite frequently in the wild, at least compared to many other animal orders. Our abilities to analyze species at the molecular level are becoming sharper as time goes on, which often results in the re-classification of existing species. 

For more information about each caudate family and the taxonomic model, see the Caudate Families, and the Taxonomic Model. For information about Taxonomy, the Linnaean System of Classification, and Cladistics, see article 0012 - Introduction to Systematics & Taxonomy.
