First Specimens of the Marine Eels <em>Venefica ocella</em> and <em>V. tentaculata</em> (Nettastomatidae) from British Columbia
Bibliographic record
Abstract
Until recently, only the following seven species of marine eels were known to exist in waters off British Columbia (based on literature sources and museum records): Nemichthys scolopaceus, and Avocettina infans (Nemichthyidae, snipe eels), Xenomystax atrarius (Congridae, conger eels), Serrivomer jesperseni (Serrivomeridae, sawtooth eels), Cyema atrum (Cyematidae, bobtail eels), Synaphobranchus affinis (Synaphobranchidae, cutthroat eels), and Thalassenchelys coheni (Colocongridae, worm eels). Histiobranchus bathybius (also in the Synaphobranchidae) is expected to occur in British Columbia, since its range extends from Mexico to Alaska. Recent surveys to determine the viability of crab fisheries facilitated the collection of non-game fishes from by-catch in bottom-trawl samples. Several eels were collected between 2004 and 2006, and they were originally identified as Serrivomer jesperseni (Serrivomeridae). Re-examination of these specimens indicates that they all are duckbill eels (Nettastomatidae), the first records of this family north of 45°39'N along the North American Pacific coast. Both Venefica ocella and V. tentaculata are represented, with V. ocella found farther north than V. tentaculata. All British Columbia specimens are housed at the Royal British Columbia Museum. The collection of new deep-water species in British Columbia reinforces the value of survey sampling to improve our knowledge of biodiversity.

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.
