Description. Body elongated and attenuated to the caudal peduncle; head small, 6.7–7.7 times in total length; snout blunt, 3.7–4.4 times into head; interorbital width about equal to horizontal diameter of orbit; long chin barbel present, strongly developed and 1.9–2.4 in head length; dorsal, pectoral and ventral fins with a single elongated ray, elongated second dorsal ray 1.8–2.4, elongated second pectoral ray 2.0–2.3 and elongated first pelvic ray 2.0– 2.2 in the head length. The main morphometric and meristic characteristics are presented in Table 4. Habitat and distribution. Benthopelagic in tropical and subtropical North Atlantic between 520 and 2,165 m depth (Geistdoerfer, 1990). Amphi-Atlantic distribution; in western Atlantic it occurs in West Greenland (a single specimen), off east coast of Florida, Straits of Florida, Gulf of Mexico and Caribbean sea and in eastern Atlantic from the northwest of Spain (Galicia), Portugal, Azores, Canary Islands, Morocco, Mauritania and Gulf of Guinea (Marshall & Iwamoto, 1973; Maul, 1976; Geistdoefer, 1990; Jørgensen, 1996; Bañón et al. 2010; Sobrino et al. 2012). Gadomus arcuatus (Goode & Bean, 1886) Fig. 4. Bathygadus arcuatus Goode & Bean, 1886: 158. Off Martinique Island, West Indies, Blake station 205, 611 m. depth. Holotype: MCZ 28007. Parr, 1946: 8–17 (description, key); Marshall & Iwamoto, 1973: 518–530 (description, key); Howes & Crimmen 1990: 192–201 (description, key). Material examined. MHNUSC 25006- 1, 566 mm TL, 13th May 2011, Avilés Canyon; 43º 57.850’N— 6º 28.050’W; 1,450 m depth. Description. Body elongated and attenuated to the caudal peduncle; upper profile to first dorsal fin strongly inclined, with a pronounced hump-backed appearance; head moderately large, 6.2 times in total length; snout 4.8 times into head; interorbital width about equal to horizontal eye diameter and 5.4 times into head length; chin barbel present and of moderate size, 0.7 in head length; mouth large and terminal jaws beyond the posterior margin of the orbit; only one pelvic ray elongated but broken is patent, all rest of elongated rays are presumably broken, elongated first pelvic rays 1.3 and elongated first pectoral rays 1.3 in the head length. The main morphometric and meristic characteristics are presented in Table 5. Habitat and Distribution. Benthopelagic in tropical and subtropical Atlantic at depths between 610 and 1,631 m (Iwamoto, 1990; Sobrino et al. 2012). Amphi-Atlantic distribution; in western Atlantic from Nova Scotia (Canada), Gulf of Mexico, Caribbean, Surinam, French Guyana, north-eastern coast of South America and Brazil and in eastern Atlantic from Morocco, Azores, Canary Islands, Mauritania, Guinea-Bissau and Gabon (Marshall & Iwamoto, 1973; Iwamoto, 1990; Geistdoerfer, 1990; Howes & Crimmen, 1990; Melo & Menezes, 2002; Melo et al. 2010; Halliday et al. 2012; Sobrino 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.
