The University of Michigan Museum of Zoology provides the searchable Animal Diversity Web database, with species accounts (images and text) of some of the world's mammals, birds, amphibians, reptiles, sharks, bony fishes, mollusks, arthropods and echinoderms. The database is searchable by common or scientific name. For each species account, information includes scientific and common name, classification (Phylum through Genus), and color photographs (many beauties). Some accounts supply additional information, such as geographic range, physical characteristics, natural history (food habits, reproduction, behavior, conservation, and habitat), other comments, and references. Although the list of species is by no means complete, these simple but effective accounts are interesting to read and will be helpful as supplemental resources in a biological diversity/ ecology course.
