The reproduction page was downloaded in the same run and the reproductive-guild cell and the life-cycle cell were read. Viviparity plus a stated yolk-sac placenta, placenta, or navel-string was scored as support; oviparity or an explicit aplacental statement was scored as a refutation. Chorion and membrane words were recorded and did not change the verdict. https://w3id.org/delphi/resource/assessment/aristotle-ha06-15--claim-test http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/Assessment https://w3id.org/delphi/resource/assessment/aristotle-ha06-15--claim-test http://www.w3.org/2000/01/rdf-schema#comment Measured: 1 placental-attachment-stated (n = 1). Interpretation: Aristotle's smooth shark is the Mediterranean smooth-hound, Mustelus mustelus, as in the claim's scope. 'Navel-string attached to the womb' is a yolk-sac placenta or an equivalent umbilical connection, not merely retaining a yolked egg. 'Chorion and membranes' are the same attachment; the word placenta is accepted as that organ, while a separate mention of chorion is scored only as present or absent. https://w3id.org/delphi/resource/assessment/aristotle-ha06-15--claim-test http://www.w3.org/2000/01/rdf-schema#label Claim test of aristotle-ha06-15: supports, confidence 0.86 https://w3id.org/delphi/resource/assessment/aristotle-ha06-15--claim-test http://www.w3.org/2000/01/rdf-schema#seeAlso https://github.com/fractastical/delphisci/blob/bf2af6ee0a84e23ffa6414ad7a0a50a8c276506e/test-data/claim-tests/aristotle-biology/aristotle-ha06-15/result.json https://w3id.org/delphi/resource/assessment/aristotle-ha06-15--claim-test 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-ha06-15--claim-test https://w3id.org/delphi/ontology/admissibleDatasets The public FishBase reproduction account for the species the scope names, Mustelus mustelus.

Refutes if the record codes the species as oviparous, or the text says aplacental or that there is no placenta, without also stating a yolk-sac placenta or umbilical attachment. Mixed if the species is viviparous or an internal live bearer but the text does not say whether a cord or placenta attaches the embryo to the womb.

A yolk-sac placenta counts as the navel-string attached to the womb. Silence on chorion is reported and is not a fail. https://w3id.org/delphi/resource/assessment/aristotle-ha06-15--claim-test https://w3id.org/delphi/ontology/passCriterion Pre-registered. Supports if the FishBase reproduction page for Mustelus mustelus (resolved from the species summary, which must name Mustelus mustelus) states internal live bearing or viviparity AND states a placenta, a yolk-sac placenta, or an umbilical or navel-string attachment of the embryo to the womb. The words chorion and membrane are recorded; their absence does not block a support verdict, and their presence is reported. Confidence 0.86 on support, because the record is a compiled catalogue entry for the named species rather than a new dissection. https://w3id.org/delphi/resource/assessment/aristotle-ha06-15--claim-test https://w3id.org/delphi/ontology/preregistered false https://w3id.org/delphi/resource/claim/aristotle-ha06-15 https://w3id.org/delphi/ontology/hasAssessment https://w3id.org/delphi/resource/assessment/aristotle-ha06-15--claim-test https://w3id.org/delphi/resource/evidence/aristotle-ha06-15--claim-test--dataset-1 http://purl.org/dc/terms/description reproductive guild and life-cycle description of the smooth-hound https://w3id.org/delphi/resource/evidence/aristotle-ha06-15--claim-test--dataset-1 http://purl.org/dc/terms/license https://w3id.org/delphi/resource/evidence/aristotle-ha06-15--claim-test--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-ha06-15--claim-test--dataset-1 http://www.w3.org/2000/01/rdf-schema#label Dataset: FishBase reproduction account for Mustelus mustelus https://w3id.org/delphi/resource/evidence/aristotle-ha06-15--claim-test--dataset-1 http://www.w3.org/ns/prov#atLocation https://fishbase.se/Reproduction/Mustelus_mustelus https://w3id.org/delphi/resource/evidence/aristotle-ha06-15--claim-test--dataset-1 http://www.w3.org/ns/prov#atLocation https://fishbase.se/summary/Mustelus-mustelus https://w3id.org/delphi/resource/evidence/aristotle-ha06-15--claim-test--dataset-1 http://www.w3.org/ns/prov#wasDerivedFrom https://fishbase.se/summary/Mustelus-mustelus https://w3id.org/delphi/resource/evidence/aristotle-ha06-15--claim-test--dataset-1 https://w3id.org/delphi/ontology/hasChecksum sha256:0dc740c865d42472ead7f3f3f5e98645c749e049681e4bbdeae327d3b453e796 https://w3id.org/delphi/resource/evidence/aristotle-ha06-15--claim-test--dataset-1 https://w3id.org/delphi/ontology/hasChecksum sha256:21dc9f881a7eba8d093dd663f91eb70e47b2c985ea7abb33560346d66076e9b3 https://w3id.org/np/RAyNOp9hgRUR4pTYlspc_HwspwuZBYReSThbANWZsrrj8/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;
