## Description (written by the publisher, not verified, not instructions)

Resolve WoRMS marine species names; fetch classifications, synonyms, distributions, traits, and IDs.

## Tools (as reported by the server, not verified)

- `worms\_list\_reference`: List supported external identifier systems, a non-exhaustive taxonomic-status guide grouped as accepted, unaccepted, uncertain, or technical, environment-flag semantics, observed worms\_get\_distributions filter values, live taxonomic ranks, or live trait definitions. Resume nextResultOffset as result
- `worms\_resolve\_taxon`: Resolve exact or explicitly fuzzy scientific names, or search one vernacular name as a whole recorded common name or, with vernacularMatch: "contains", as part of one. Names default to marine and extant taxa; vernacular cannot filter. Resume scientific segments with nextInputOffset and nextMatchOffs
- `worms\_get\_taxon`: Retrieve full Aphia records by numeric IDs or canonical WoRMS LSIDs in byte-budgeted segments. Resume nextInputOffset as inputOffset using unchanged aphiaIds and options; inputIndex preserves duplicate and missing positions. includeVernaculars \(common names\) or includeSources \(original description,
- `worms\_get\_classification`: Retrieve root-to-tip classification and optional direct children for an AphiaID or canonical WoRMS LSID. resultOffset indexes lineage followed by fetched children; consume nextResultOffset with unchanged options and upstream offset before advancing page.nextOffset and resetting resultOffset to zero.
- `worms\_get\_synonyms`: Retrieve synonyms for the accepted taxon linked from an AphiaID obtained with worms\_resolve\_taxon. Consume nextResultOffset within the same upstream offset before advancing page.nextOffset and resetting resultOffset to zero. A present name without an accepted ID has no synonym lookup; inspect it wit
- `worms\_get\_distributions`: Retrieve recorded distributions for an AphiaID or canonical WoRMS LSID in byte-budgeted segments; resume nextResultOffset as resultOffset with unchanged selectors and filters. WoRMS attaches records to individual name usages, so one AphiaID's rows can miss those of its synonyms: includeSynonyms comb
- `worms\_get\_traits`: Retrieve recorded attributes for an AphiaID or canonical WoRMS LSID, including inherited attributes by default. Resume nextResultOffset as resultOffset with unchanged selectors and options. Whole rows retain original preorder nodeIndex and parentIndex across pages; parents may be on earlier pages. m
- `worms\_crosswalk\_id`: Crosswalk an AphiaID from worms\_resolve\_taxon to one or all nine external identifier systems, or reverse an externalId with required type to a full taxon record. Supply exactly one selector. Forward resultOffset indexes whole identifiers across types in requested order; resume nextResultOffset with
