This site provides as much information as any good Internet encyclopedia, yet it doesn’t contain a single Web page. Instead of housing static pages about different species, it compiles a profile of your selected organism by linking to molecular, taxonomic, and other sites. Enter “aardvark,” for example, and the engine tracks down images of the mammal, protein and DNA sequences, a list of abstracts from recent papers, and a classification synopsis from the Integrated Taxonomic Information System.
