dc:description "Fetched the FishBase species summary, followed the FishReproSummary link, and searched only the slice from the Mode field through the life-cycle paragraph. Separate-sex wording and egg, spawning, fecundity, or larva wording were matched with the pre-registered expressions. OBIS was queried with facets=lifeStage and size implied by the facet endpoint; buckets whose labels match egg, larva, or leptocephalus were summed. The HTML navigation label 'Eggs' is outside that slice.";
<http://www.w3.org/2000/01/rdf-schema#comment> "Measured: 1 1 if the reproduction mode matches separate sexes, else 0 (n = 1). Interpretation: Aristotle's eel is the European eel, Anguilla anguilla. 'Neither male nor female' is separate sexes in the reproduction record. 'Engenders nothing' and 'no eel has ever been seen with an egg' are eggs, spawning, fecundity, or a leptocephalus larva. Other Anguilla species are out of scope for the verdict.";

It is refuted if the reproduction mode matches dioecism, dioecious, gonochorism, gonochoristic, or separate sexes, or if the reproduction text matches egg, eggs, spawning, fecundity, leptocephalus, larva, or larvae, or if an OBIS life-stage bucket labelled egg, larva, or leptocephalus has a count of at least 1. If the summary page cannot be retrieved and OBIS returns no life-stage facet, the verdict is inconclusive with reason data-unavailable.
