The ITIS includes documented taxonomic information of flora and fauna from both aquatic and terrestrial habitats. It contains information on plants, animals, fungi, and microbes of North America and the world. For each scientific name, ITIS includes the authority (author and date), taxonomic rank, associated synonyms and vernacular names where available, a unique taxonomic serial number, data source information (publications, experts, etc.) and data quality indicators.
The ITIS and Species 2000 Catalogue of Life (CoL) partnership is proud to provide the taxonomic backbone to the Encyclopedia of Life (EOL).
