. . . . "Downloaded the FishBase v26.06 reproduc table, selected the column whose values match the manual's reproductive-mode vocabulary, and counted distinct SpecCode values. Dioecism, protandry, protogyny and true hermaphroditism were coded as testicular, following the manual's definition that dioecism is males developing testes. Parthenogenesis was not. Snakes are not in this table. A testicular count of at least 100 refutes the joint claim." . . "Measured: 14297 FishBase species with a reproductive mode the manual ties to testicular tissue (n = 14299, compiled modes, not a new dissection; one row-group per stock collapsed to SpecCode). Interpretation: Aristotle treated the elongate male organs of fishes as spermatic ducts rather than testes. This test asks whether the public fish-reproduction compilation records modes that its own manual defines as involving testes. It does not re-section the gonad. A refutation from fishes refutes the joint statement. Snakes are not in FishBase and are not measured here." . "Claim test of aristotle-ga01-05: refutes, confidence 0.8" . . .

Refutes the joint claim if the number of testicular fish species is at least 100, because the claim says fishes have no testes at all and fishes are inside its scope. Mixed if the testicular count is between 1 and 99 inclusive. Inconclusive with reason underpowered if fewer than 100 species have a recognized mode. Inconclusive with reason data-unavailable if the parquet cannot be fetched or no column matches the vocabulary. Inconclusive with reason other if there is no SpecCode column. A fish pass with serpents unmeasured is inconclusive with reason underpowered for the joint claim, and the fish count is still reported." . "0.8"^^ . . "refutes" . "If fishes have no testes, the FishBase reproduction table will not record a reproductive mode that the FishBase manual defines as males developing testes, or as hermaphroditism that includes testicular tissue." . "Count distinct SpecCode values by mode class. The manual's definition of dioecism (males develop testes, females develop ovaries) is the mapping from mode to 'testes present'. Thresholds are 0 versus at least 100 testicular species, as stated in the pass and fail criteria. Rows are not double-counted within a SpecCode." . "Pre-registered. Using FishBase snapshot fb/v26.06 table reproduc.parquet, identify the mode column as the column whose non-null values intersect the manual's vocabulary (dioecism, protandry, protogyny, true hermaphroditism, parthenogenesis), allowing case and spacing differences. The unit is a distinct SpecCode. A species is recognized if any row has a vocabulary mode. A species is testicular if any row has dioecism, protandry, protogyny, or true hermaphroditism. Parthenogenesis does not count as testicular. The fish component supports 'no testes' only if the number of recognized species is at least 100 and the number of testicular species is 0. The joint claim (fishes and serpents) is supported only if the fish component supports it and a serpent dataset with the same rule also supports it. No serpent dataset is planned in this registration, so a fish pass does not by itself support the joint claim." . "false"^^ . .
