As pf Jan 17, 2009,, there are 6449 species of amphibians according to AmphibiaWeb (http://amphibiaweb.org/aw/about/index.html). Amphibian Species of the World (http://research.amnh.org/herpetology/amphibia/index.php) gives 6347 as of 15 July 2008. The difference reflects the rate of discovery, which is currently very rapid, although species are going extinct right now faster than they are being discovered.

Why are worldwide amphibian populations decreasing what can be done to prevent the population from decreasing?
Amphibians, a unique group of vertebrates containing over 6,300 known species, are threatened worldwide. A recent assessment of the entire group (iucnredlist.org/amphibians) found that nearly one-third (32%) of the world's amphibian species are threatened, representing 1,856 species. Amphibians have existed on earth for over 300 million years, yet in just the last two decades there have been an alarming number of extinctions, nearly 168 species are believed to have gone extinct and at least 2,469 (43%) more have populations that are declining. This indicates that the number of extinct and threatened species will probably continue to rise (Stuart et al. 2004). Amphibian diversity is highest in the tropics and Brazil has the most described species at 811 species. By contrast, the United States is nearly the same size as Brazil but has 292 species (as of January 22, 2009).
