Where it has been recorded

20 places from 41 openly licensed, georeferenced records out of 121 in GBIF. Records are as identified by their publishers; tardigrade identifications from older surveys are often uncertain. Datasets: Terrestrial and limnic invertebrates systematic collection, NTNU University Museum (23), Invertebrates Collection of the Swedish Museum of Natural History (7), Norwegian Species Observation Service (4), Records from iRecord not covered by a national recording scheme (3), Bioblitz 2013 Copenhagen Denmark (2).

Papers

7 works in our corpus of 5,137 tardigrade papers name it in the title or abstract (0 in the title), from 1994. This is by exact name match, so it misses papers that use an older name or only the genus.

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.
