Description. Body shape eel-like, moderately compressed, elongated and attenuated to the caudal peduncle; top of snout and head scaleless, opercle scaled; head depressed anteriorly, the interorbital length is contained 4.8– 6.2 times in the head length; dorsal origin slightly posterior to pelvic origin; first dorsal ray segmented and as long as 2nd dorsal ray; pectoral fin long and narrow, almost reaching to the base of the dorsal fin and contained 1.2–1.3 times in the head length; a deeply pigmented sheath of the lateral line composed by enlarged scales; pyloric caeca long, creamy white in colour, arranged in a single row at the base. The main morphometric and meristic characteristics are presented in Table 3. FIGURE. 2 Halosauropsis macrochir from the northeastern Atlantic Ocean, MHNUSC 25009- 5, 566 mm total length. Habitat and distribution. Benthopelagic on the lower slope, rise and seamounts, between 1,100 and 3,300 m depth. Cosmopolitan: eastern Atlantic from Ireland to Mauritania and South Africa; central Atlantic, along the Mid-Atlantic Ridge; western Atlantic, including Canada to 25°N, and off southern Brazil; western Pacific, including Australia, New Zealand and Japan; and western Indian Ocean (Sulak 1986a; Bergstad et al. 2012).

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.
