How this is built
Data
Classification, authority and notes from Degma & Guidetti's 2026 world checklist. Records from GBIF, genomes and sequencing runs from NCBI, papers from our OpenAlex corpus of tardigrade literature, photos from Wikimedia Commons and iNaturalist (CC0 or CC BY), and facts from our knowledge graph, each with its source and page. A page shows only the parts we hold for that species.
Built with
build_species.py writes every species page from the checklist, joining each name by exact match to the other collections. Facts are ranked by confidence and evidence, and taken from each source in turn so no single paper fills the list. The records map is drawn as SVG from thinned GBIF coordinates.
Checked
Only exact matches to accepted names bring in GBIF records, and fossil entries were read against their papers. The pages themselves are not tested against data.
Limits
Exact name matching misses papers and sequences filed under older names or only the genus. GBIF identifications are as their publishers made them. A short page means we hold little yet, not that little is known.
