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. https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/Assessment https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 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. https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 http://www.w3.org/2000/01/rdf-schema#label Claim test of aristotle-ha04-28 (pr-101): refutes, confidence 0.84 https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 http://www.w3.org/2000/01/rdf-schema#seeAlso https://github.com/fractastical/delphisci/blob/bf2af6ee0a84e23ffa6414ad7a0a50a8c276506e/test-data/claim-tests/aristotle-biology/aristotle-ha04-28/pr-101/result.json https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 http://www.w3.org/ns/prov#wasAttributedTo https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 https://w3id.org/delphi/ontology/admissibleDatasets A public species account of Anguilla anguilla, the European eel of the Mediterranean and eastern Atlantic, plus a public occurrence store that separates life stages.

The reproduction table itself was not downloaded, and the expressions above were fixed from the claim rather than from that snippet. The verdict is the scripted match on the retrieved page. https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 https://w3id.org/delphi/ontology/evidenceAgainst Silver eels mature at sea.

The claim is a universal negative, so one recorded counterexample refutes it. 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. If the page is retrieved but contains no reproduction mode and OBIS has no life-stage facet, the verdict is inconclusive with reason other. https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 https://w3id.org/delphi/ontology/hasConfidence 0.84 https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 https://w3id.org/delphi/ontology/hasEvidence https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-1 https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 https://w3id.org/delphi/ontology/hasEvidence https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-2 https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 https://w3id.org/delphi/ontology/hasVerdict refutes https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 https://w3id.org/delphi/ontology/hypothesis If the eel is neither male nor female and produces no offspring, the FishBase reproduction record for the European eel Anguilla anguilla does not describe separate sexes, and neither that record nor OBIS life-stage counts record eggs or larvae. https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 https://w3id.org/delphi/ontology/inferenceMethod The reproduction block linked from the FishBase species summary is matched with the pre-registered expressions.

The FishBase reproduction record for Anguilla anguilla was retrieved and its mode states that the sexes are not separate (wording such as no distinguishable sex, no gonads, or sexless), the reproduction text does not match egg, eggs, spawning, fecundity, leptocephalus, or larva/larvae, and the OBIS life-stage facet for Anguilla anguilla, if retrieved, has a zero count for every bucket whose label matches egg, larva, or leptocephalus. https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 https://w3id.org/delphi/ontology/preregistered false https://w3id.org/delphi/resource/claim/aristotle-ha04-28 https://w3id.org/delphi/ontology/hasAssessment https://w3id.org/delphi/resource/assessment/aristotle-ha04-28--claim-test--pr-101 https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-1 http://purl.org/dc/terms/description reproduction mode and life-cycle text of the European eel https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-1 http://purl.org/dc/terms/license https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-1 http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/EvidenceItem https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-1 http://www.w3.org/2000/01/rdf-schema#label Dataset: FishBase species summary for Anguilla anguilla https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-1 http://www.w3.org/ns/prov#atLocation https://www.fishbase.se/Reproduction/FishReproSummary.php?ID=35&GenusName=Anguilla&SpeciesName=anguilla&fc=49&StockCode=45 https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-1 http://www.w3.org/ns/prov#atLocation https://www.fishbase.se/summary/Anguilla-anguilla.html https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-1 http://www.w3.org/ns/prov#wasDerivedFrom https://www.fishbase.se/summary/Anguilla-anguilla.html https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-1 https://w3id.org/delphi/ontology/hasChecksum sha256:7d738a828759cdcd9dddf537f60e39dd91c4c19d0f5601f63eb1611edb10f379 https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-1 https://w3id.org/delphi/ontology/hasChecksum sha256:a21e700301cab21b84f134aa4cd767c504c21fb3dbc230266595597f463526fb https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-2 http://purl.org/dc/terms/description counts of egg and larval occurrence records, without downloading occurrences https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-2 http://purl.org/dc/terms/license https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-2 http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/EvidenceItem https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-2 http://www.w3.org/2000/01/rdf-schema#label Dataset: OBIS occurrence life-stage facet for Anguilla anguilla https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-2 http://www.w3.org/ns/prov#atLocation https://api.obis.org/v3/facet?scientificname=Anguilla%20anguilla&facets=lifeStage https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-2 http://www.w3.org/ns/prov#wasDerivedFrom https://obis.org/ https://w3id.org/delphi/resource/evidence/aristotle-ha04-28--claim-test--pr-101--dataset-2 https://w3id.org/delphi/ontology/hasChecksum sha256:ee7e3177676f8804a8d394cdf67fbf03ae75c46184499a40e303877973c9b07a https://w3id.org/np/RAdNc5_IFrG72tB7PHNz0paMmdO5LHn78xZda7JqUPF6k/provenance https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://www.w3.org/ns/prov#SoftwareAgent https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 http://www.w3.org/2000/01/rdf-schema#label delphisci claim tester (grok-4.7;
