ITIS
The Integrated Taxonomic Information System (ITIS) provides authoritative taxonomic information on plants, animals, fungi, and microbes of North America and the world. ITIS compiles standardized scientific names, common names, taxonomic serial numbers (TSNs), hierarchical classification, and associated metadata curated through interagency and international collaboration to support biodiversity data integration, ecological research, regulatory processes, and interoperability across biological information systems.
