The widespread occurrence of frogs and other amphibians is a sign of a healthy ecosystem. Perhaps the widespread availability on the Internet of information about frogs is a sign of a healthy "infosystem." Anyway, here are some sites to explore if you are looking for information to use in biology classes. Unless otherwise noted, you will need a World Wide Web browser like Mosaic to access the information.

The Imaging and Distributed Computing Group of Lawrence Berkeley Laboratory has an interactive frog dissection kit on the Internet. Images of the frog from various views, and in various stages of dissection, are generated on-the-fly based on parameters set by the user. The URL is:

The University of Virginia/The Curry School of Education's Instructional Technology Program has developed another interactive frog dissection tutorial. The tutorial combines text with 60 in-line color images and 17 QuickTime movies illustrating dissection procedures and internal organs. Numerous clickable image maps provide interactive practice. The URL for this site is:

Sandra Loosemore at Yale University maintains The Froggy Page, a site containing links to frog pictures, frog sounds, stories about frogs ("The Frogs" by Aristophanes, Grimm Brothers' "The Frog Prince"), words to songs about frogs, and information about the most famous frog, Kermit. The URL for this site is:

The Australian National Botanic Biodiversity Server includes a section on the frogs in the Australian National Botanic Gardens. The URL is:

Finally, there is Frog-Net, an electronic forum for researchers engaged in the study of the behavior and the underlying neural mechanisms in amphibians. The list is moderated by Jim-Shih Liaw, Department of Computer Science and Program in Neuroscience, University of Southern California.
