Call it a virtual initiative to help a variety of animals, many of whose ancestors shared space with dinosaurs. The decline of amphibians has spurred a group of volunteers who run www.amphibiaweb.org: an online system that enables anyone with a web browser to look up information relating to amphibian biology and conservation. The site was developed in conjunction with the Digital Library Project at the University of California, Berkeley.

It offers taxonomic information for more than 6,000 species that live on land and water. Accounts added to the site by volunteers
