Abstract

fetched live from OpenAlex

Abstract Frequent tail loss has been reported in a variety of reptiles including sphenodonts, lizards, amphisbaenids, and snakes. We report evidence of non-specialized pseudoautotomy as an antipredator defense in the Eastern Ribbon Snake Thamnophis sauritus. In field studies in Nova Scotia, Canada, T. sauritus were frequently found with partial tails, during three capture attempts T. sauritus tails became completely or partially detached, and one detached tail twitched repeatedly after separation. The breakage was intervertebral, suggesting pseudoautotomy (i.e., that the snake's tail anatomy was not specialized for easy tail loss). Although tail loss patterns in T. sauritus have been well documented, to our knowledge this is the first time pseudoautotomy has been reported in T. sauritus.

Full frame distilled prediction

Teacher imitation

Not 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.
