. . . . "analysis.py matched AnAge and PanTHERIA column names to mating posture, tentacle interlacing, mouth-to-mouth and copulatory position, and searched the FishBase SPECIES, reproduction and morphology manuals plus the REPRODUCTION table manual. No posture column and no pre-registered posture token was found. The WoRMS record for Octopus vulgaris returns taxonomic fields only. No species was assigned a posture, so no modal class was computed." . . "Measured: 0 columns matching the pre-registered variable (n = 86). Interpretation: The same paragraph distinguishes the shared posture (mouth to mouth, tentacles interlaced, suckers in contact) from a report Aristotle attributes to others, that the male has a penis in one tentacle which enters the funnel. Only the shared posture is the claim. A modern hectocotylus description counts as that claim only when the record also states the mouth-to-mouth or tentacle-interlacing posture. WoRMS names are admissible for placing a species in a group, not as evidence of how it mates." . "Claim test of aristotle-ha05-08: inconclusive, confidence 0.86" . . . "A public species-level table from FishBase or another listed source (AnAge, PanTHERIA, AVONET, GBIF, NCBI, WoRMS, PBDB) or a checksummed paper supplement, with a mating-posture or copulatory-position field and a taxon assignable to the three groups. Licence stated. A narrative encyclopedia page is not a table." . "claim-test/0.1.0" . "none" . "The modal postures of at least two groups differ, or a group with at least two scored species has no mouth-interlace record. No posture column does not disconfirm the claim." . "FishBase describes reproduction with mode, fertilization and spawning fields. Those fields are not the mouth-to-mouth posture tokens fixed before download." . "The WoRMS taxon page states that the webpage text is licensed under a Creative Commons Attribution 4.0 License. The page is not a posture table." . "Zero of the three groups has a posture record. The pre-registration calls that data-unavailable, and it says a taxonomic list is not a mating posture." . "In each of Octopoda, Sepiida and the squid orders, the modal recorded mating posture is mouth-to-mouth tentacle interlacing, and that class covers at least half of the species with a posture record in the group." . "Pre-registered. The claim is refuted if at least two groups have posture records and their modal classes differ, or if any group with at least two scored species has zero mouth-interlace records. Mixed if every group has at least one matching species but one group's modal class is not mouth-interlace. If no posture field exists, or fewer than two of the three groups have any posture record, inconclusive with reason data-unavailable. A taxonomic list of the three groups, a spermatophore-length column, or a 'reproduces sexually' flag is not a mating posture." . "0.86"^^ . . . . . "inconclusive" . "If the octopus, the cuttlefish and the squid mate in the same way, uniting at the mouth by interlacing tentacles, then a species-level mating-posture table will show that posture as the modal recorded posture in each of the three groups." . "Species are classed by the pre-registered tokens into mouth-interlace versus other. The denominator in each group is the number of species with a non-missing posture. The modal class and its share are compared across the three groups. Support requires the same modal class, mouth-interlace, at a share of at least one half, in all three. Differing modes refute. A missing field is data-unavailable." . "Pre-registered. Quote: 'Molluscs, such as the octopus, the sepia, and the calamary, have sexual intercourse all in the same way; that is to say, they unite at the mouth, by an interlacing of their tentacles.' Groups: octopus = order Octopoda; cuttlefish = order Sepiida (sepia); squid = Teuthida, Oegopsida, Myopsida or family Loliginidae (calamary). A species matches the claimed posture if its posture field contains one of these tokens: 'mouth to mouth', 'mouth-to-mouth', 'head to head', 'tentacles interlac', 'arms interlac', 'beak to beak'. A hectocotylus or mantle-cavity insertion, with none of those tokens, is a different posture and does not match. The claim passes only if each of the three groups has at least one species with a posture record, the modal posture class in each group is the mouth-interlace class, and that class is at least half of the species with a posture record in that group." .
