Species Search

Biological taxonomy is the framework scientists use to organize life on Earth. Every species is placed in a nested hierarchy — Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species — originally formalized by Carl Linnaeus in the 18th century and refined continuously as new molecular evidence emerges. Modern phylogenetics, which reconstructs evolutionary relationships from DNA sequence data, has reshaped many historical groupings and continues to move species between branches of the tree of life. The Species Search tool lets you explore this structure across more than 370,000 indexed organisms, combining a fast text search with kingdom and IUCN Red List filters so you can answer questions like which mammals are endangered, what plants belong to a given family, or which fungi have been recorded in a region. Results are drawn from public biodiversity databases including GBIF, IUCN, NCBI, and Wikidata, and every card links to a full species profile with taxonomy, conservation status, population trends, habitat description, and geographic range. Use it as a starting point for field research, conservation planning, academic coursework, citizen-science projects, or simply to discover the extraordinary diversity of life on our planet.
