The endemic Iranian Cave-fish,<i>Iranocypris typhlops</i>: two taxa or two forms based on the mental disc?
Bibliographic record
Abstract
The objective of this study was to investigate morphometric and meristic characteristics of Iranocypris typhlops, comparing new material having a mental disc with those lacking a disc. 24 morphometric and 9 meristic variables were measured. Statistical analyses used cluster and discriminant methods, which showed significant morphometric differences between the two groups (Wilk’s Lambda, p<0.05). Additionally, fish with a disc had less pectoral and pelvic rays compared to fishes without a disc. Fishes without a disc generally had a bipartite swimbladder; in contrast, fishes with a disc had unipartite and bipartite swimbladders in an equal ratio. There may also be some differences in feeding habits between these two groups. Fish with a disc can attach to and graze on the substrate. A significantly longer intestinal length in fishes with a disc may also be indicative of a detrital feeding habit.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
