Catalogue of Life
This growing database will eventually become a comprehensive listing of all known species of organisms on Earth. (A partner with the Integrated Taxonomic Information System (ITIS) – see below) Includes genus, distribution, life zone, and links to online resources. Site visitors may search using common or scientific names or browse data via a taxonomic tree listing eight kingdoms: Animalia, Archaea, Bacteria, Chromista, Fungi, Plantae, Protozoa, and Viruses. Clicking on Taxonomic Classification leads to a search form with fields including Top Level Group (kingdom), Phylum, Class, Order, Superfamily, Family, Genus, Species, and Infraspecific Taxon.
