ITIS
The Integrated Taxonomic Information System (ITIS, www.itis.gov) partners with specialists from around the world to assemble scientific names and their taxonomic relationships and distributes that data openly through publicly available software. The ITIS mission is to communicate a comprehensive taxonomy of global species that enables biodiversity information to be discovered, indexed, and connected across all human endeavors. ITIS is made up of 11 active MOU partners committed to improving and continually updating scientific and common names of all seven Kingdoms of Life (Archaea, Bacteria, Protozoa, Chromista, Fungi, Plantae, and Animalia).
