zenodo.communities

Search Zenodo Communities

Search Zenodo communities — curated subject-specific collections maintained by researchers and institutions. Communities group related records by discipline, project, or institution (e.g. "astronomy", "bioinformatics", "EU Horizon projects", "CERN data"). Returns community ID, title, description, and URL. Each community has a dedicated landing page on Zenodo with all its member records. Use the community ID with the Zenodo website to browse records within a specific collection. Zenodo currently hosts 5,000+ communities covering all scientific disciplines.

worms.species.details

WoRMS Species Details

Retrieve the full WoRMS Aphia record for a taxon by its AphiaID. Returns complete taxonomy (kingdom to genus), accepted name and authority, valid AphiaID for synonyms, citation string, LSID (life science identifier), habitat flags, and last-modified date. Use this to resolve synonym chains — if status is "unaccepted", valid_AphiaID points to the accepted taxon. Source: World Register of Marine Species, CC BY 4.0.

WoRMS Species Search

Search 240K+ accepted marine species by scientific or partial name in the World Register of Marine Species (WoRMS). Returns AphiaID, accepted scientific name, authority, taxonomic status, kingdom/phylum/class/order/family/genus, LSID, and habitat flags (marine/brackish/freshwater/terrestrial/extinct). Supports fuzzy matching and optional restriction to marine-only taxa. Use the AphiaID from results with worms.species.details, worms.species.classification, or worms.species.vernaculars.

worms.species.classification

WoRMS Taxonomic Classification

Get the full taxonomic classification tree for a marine taxon by AphiaID. Returns the complete nested hierarchy from Superdomain/Biota down to the queried taxon — each node has AphiaID, rank, and scientific name. Ideal for building taxonomic trees, verifying rank placement, or navigating the WoRMS backbone. Source: World Register of Marine Species, CC BY 4.0.
