This incredibly comprehensive database of amphibians includes mention of over 35,000 species. Not only packed with information, however, the database is also easily navigable by either searching or exploring. "There are two finding aids, SEARCH and the EXPLORE. These allow you to search on any 4-letter string (excluding such generally used terms such as frog, salamander, caecilian, newt, et al.) SEARCH will search either on taxonomic names (active or synonyms) or geographic place names." Each species account includes the class, order, family, and genus, as well as mention of the common name and the species' distribution. A great resource for those researching this fascinating class of animals. This site is also reviewed in the April 30, 2004 _NSDL Life Sciences Report_.
