Diagnosis. Exoskeleton rather thin. Rostrum shorter than eyestalk, slightly ascending, apex acute. Carapace with middorsal carina not quite extending to posterior margin, with Y-shaped carina running along branchial region, carina running postero-ventrally from orbital region. Stylocerite acute, longer than eye. Base of thickened flagellum of antennule particularly broad. Scaphocerite with lateral tooth exceeding blade. Third maxilliped setose. Pereopods 1, 2 chelate, pereopod 1 setose, pereopod 2 with strong spines on carpus, merus and ischium; fingers of chelae shorter than palm, crossing at apices. Pereopod 3 thread-like, pereopods 4, 5 short, with blade-shaped dactyls. Only abdominal somite 4 with dorsal carina, extending into posterior tooth. Telson with dorsal groove, rounded apex armed with 6–9 spines, shorter than uropods. Male total length 70 mm, female to 93 mm. Color in life. Scarlet, eye amber to bronze (Butler 1980). Habitat and depth. Pelagic, 500–1300 m. Range. Indo-West Pacific, Canada to Baja California, Chile, Atlantic Ocean. Type locality "east coast of United States.”
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
