. . . . "The FishBase species summary was downloaded to confirm the page is Mustelus mustelus, the smooth-hound. 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." . . "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." .

"FishBase is a compiled catalogue. The life-cycle sentence cites other references; this test did not re-dissect a shark." . "No licence statement was present in the two retrieved HTML pages." . "The test is for Mustelus mustelus only, the species named in the claim's scope." . "The words chorion and membrane are not in the life-cycle sentence, so that clause of the claim is untested." . "The smooth-hound record says the species is viviparous and that embryos are attached to the womb by a yolk-sac placenta or an equivalent navel-string." . "Pre-registered. 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. Inconclusive, reason data-unavailable, if the page is missing, is not Mustelus mustelus, or has no life-cycle description. Confidence 0.80 on a refute." . "0.86"^^ . . "supports" . "If the claim holds, FishBase's reproduction record for the smooth-hound Mustelus mustelus describes live young that remain attached to the mother by a placental or navel-string connection after the yolk is used, rather than eggs laid outside the body or aplacental yolk-sac viviparity." . "Read the reproductive guild and the life-cycle description. A yolk-sac placenta counts as the navel-string attached to the womb. Silence on chorion is reported and is not a fail." . "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." . "false"^^ . .
