Cross-database view
GTDB
id: s__Pyrococcus furiosus · GTDB R232
Database's species id. At its weakest, linked by GTDB's own NCBI species id rather than the genome's raw one.
d__Archaea;p__Methanobacteriota_B;c__Thermococci;o__Thermococcales;f__Thermococcaceae;g__Pyrococcus;s__Pyrococcus furiosus
Only 3 genomes — below the threshold for detecting a split, so “current” here means unverified, not confirmed.
SILVA
Pyrococcus furiosus
id: AB603518 · SILVA 138.2
Walked up to species. At its weakest, linked by walking up 1 level from a strain or subspecies record to the species.

Greengenes2
Pyrococcus furiosus
id: Pyrococcus furiosus · Greengenes2 2024.09
Genome accession. Linked via GTDB R220 genome accessions — the same physical genomes, not a name match.
d__Archaea; p__Methanobacteriota_B; c__Thermococci; o__Thermococcales; f__Thermococcaceae; g__Pyrococcus; s__Pyrococcus furiosus
Only 1 genome — below the threshold for detecting a split, so “current” here means unverified, not confirmed.
Renamed: Greengenes2 gives this taxon a different name in 2022.10, 2024.09.
eHOMD
Release 4.2No record in eHOMD 4.2.
Each panel shows one release. Switch a release to see how that database's answer changes — the taxon is held fixed by NCBI taxid, so every panel describes the same organism. Each panel also says how it was linked; how the databases are joined explains the routes.

Each column is the release its box shows. marks the first rank at which a database's name differs from NCBI's, by exact text; a suffix such as _A counts. SILVA's path and eHOMD's columns end at genus, so their species row is blank; the box above names the species. Levels a source labels outside these seven ranks are in the API's ranks and not drawn here.
