Quantifying fin shape in <i>Brachioteuthis beanii</i> (Cephalopoda: Brachioteuthidae) collected at The Gully Marine Protected Area, off Nova Scotia, Canada
Bibliographic record
Abstract
Oegopsid squid fin shape changes with ontogeny, and identifying the timing of these changes may distinguish between phases and stages of cephalopod life cycles. Fin shape of Brachioteuthis beanii was analyzed in 67 specimens (41–105 mm ML) divided into five groups based on size and sex. Male and female adult fins are the same shape, but the adult shape is different from juvenile and subadult shape. The Angle of Maximum Height and Width were similar across B. beanii in the size groups treated (AM x H =16° ± 2° and AM x W = 70° ± 3°). In brachioteuthids, the difference between a saggitate fin and a rhomboidal fin may be a function of life cycle phase.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
