Visual morphology and feeding behaviour of the daggertooth
Bibliographic record
Abstract
Dissection of freshly eaten prey suggests that the North Pacific daggertoothAnotopterus nikparinisever the spine of small prey with a single slashing blow. The bite marks indicate that the immobilized prey is manipulated and swallowed head first. Frequent evidence suggests daggertooth wound prey which are too large to consume whole by cutting off strips of flesh. In either case the wounds consist of a single prominent slash mark on one side and a series of inconspicuous marks on the opposite side. Retinal morphology provides supporting evidence that daggertooths are visual ambush predators that attack prey from below, and should be considered as epipelagic rather than mesopelagic fish. Visual acuity appears to be high, suggesting that frequent attacks on prey too large to be killed immediately is not error, but a well‐defined feeding behaviour. The daggertooth may be a significant source of mortality for economically important fish such as all sizes of salmon.

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.
