Squatina californica Ayres 1859
Bibliographic record
Abstract
Squatina californica Ayres, 1859. Pacific Angel Shark. To 175 cm (68.9 in) TL (Ebert et al. 2013). Clover Point, Vancouver Island (48°24’N, 123°21’W) (King and Surry 2016) to Gulf of California (Bizzarro et al. 2007). Reports from Chile are erroneous (Cailliet et al. 2020), and those from Peru are unlikely (Cornejo et al. 2015). One old, unverifiable record from south-eastern Alaska (Evermann and Goldsborough 1907; Mecklenburg et al. 2002); southern Chile record (Eschmeyer and Herald 1983) not verifiable. Co-occurs with Squatina armata (Philippi, 1887) off Peru. Depth: intertidal to 205 m (672 ft) (min.: Carlisle et al. 1960; max.: Robertson and Allen 2008). Previously Torpedo californica Ayres, 1855.
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.
