Complete Anuran Species Database


Hyla intermedia - photo courtesy of Paolo Mazzei, http://www.herp.itThere are more than 4,500 recognized anuran species, making the anura the largest of the three amphibian orders. Frogs also have the widest distribution, which includes just about every habitat imaginable, with high concentrations in the tropics. The distribution map at below shows the approximate global range of anurans. The largest of the thirty anuran families is Leptodactylidae, comprised of over 1,100 species, followed by Hylidae at more than 800 species, and Ranidae at more than 700 species. Allophrynidae, Nasikobatrachidae, and Rhinophrynidae are the smallest families, all containing a single species.

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.
