Postembryonic development of <i>Tanystylum bealensis</i> (Pycnogonida, Ammotheidae) from Barkley Sound, British Columbia, Canada
Bibliographic record
Abstract
All developmental stages of Tanystylum bealensis are described. This is the first complete developmental series of a pycnogonid species collected from a natural, rather than a laboratory-reared population. Development proceeds through a series of nine instars from egg to adult, with major defining characteristics of the instars being the addition of walking legs, loss of chelifores, and modification of larval appendages into adult palps and ovigers. All stages are free-living on the hydroid Plumularia setacea, except for the first instar (protonymphon), which remains on the ovigers of the adult male for a short time after hatching. Development in T. bealensis is compared to development in both the closely related species T. orbiculare and to the more distantly related Achelia alaskensis.
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.
How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
