Abstract
Abstract The Common Wolf snake, Lycodon aulicus capucinus, is a species known to feed on durophagous prey such as skinks. Here we examine in detail the dentitional morphology of L. aulicus capucinus to see whether it possesses morphological specialisations for durophagy comparable to those found in other squamates. We find that L. aulicus capucinus has greatly enlarged anterior maxillary teeth, followed by a large diastema. At the diastema, the maxilla is significantly arched. The diastema is followed by a row of small, closely-packed teeth. Finally, after a short second diastema are enlarged, but ungrooved posterior maxillary fangs, with the posterior surfaces modified into blades. We propose that this dentition helps L. aulicus capucinus to ingest hard-bodied skinks in several ways: The enlarged anterior teeth and arched maxilla encircle the prey during biting, preventing it from being squeezed out of the mouth anteriorly, the short, spatulate teeth may catch under the scales of the prey, preventing escape during swallowing, and the bladelike posterior fang may slice through the hard, cycloid scales of the prey.

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 it
