TraitBank® is a searchable, comprehensive, open digital repository for organism traits, measurements, interactions and other facts for all taxa across the tree of life. TraitBank currently features over 11 million records related to more than 330 attributes for 1.7 million taxa obtained from over 50 data sources. TraitBank is integrated into the fabric of EOL, and leverages its existing infrastructure for names, content organization, curation roles and search. Data records are aggregated from databases, literature tables, and other sources. All data are subject to curation by EOL curators. For each data record, TraitBank displays all of the related information we receive from the data provider, including its provenance, attribute definitions, measurement methods, and related data elements from the same set. Using the data search tool you can find and download all data TraitBank holds for each attribute of interest. You can search and filter by specific values and by taxon, and can sort the results.
