Animal Diversity Web (ADW)
An online database of animal natural history, distribution, classification, and conservation biology. (University of Michigan)
ADW has thousands of species accounts including text, pictures of living animals, photographs and movies of specimens, and/or recordings of sounds. Since students write the text of these accounts, we cannot guarantee their accuracy.
ADW also contains descriptions of levels of organization above the species level, e.g., phyla, classes, and in some cases, orders and families. Hundreds of hyperlinked pages and images illustrate the traits and general biology of these groups. Professional biologists prepare this part.
