taxa
Identifier
Section titled “Identifier”Description
Section titled “Description”Canonical identity for live NCBI taxonomy nodes.
One row per current NCBI taxon ID, including taxa at every rank and unranked taxa; species and organism labels are classifications of a taxon, not separate entity types.
taxon_id is stored as a string because it is an opaque external identifier.
Resolve a superseded ID by testing taxon_id and then merged_taxon_ids.
IDs in ncbi_taxonomy.deleted_nodes have no live replacement and are not represented here.
Read names, rank, ancestry, and other taxonomy attributes from ncbi_taxonomy.

Section titled “Partitions”Not partitioned.
