Sea spiders of the Salish Sea : comparative morphology and molecular phylogenetic analysis of seven coastal species (Arthropoda, Pycnogonida)
Bibliographic record
Abstract
The Pycnogonida are a clade of strictly marine arthropods with global distribution and a predominantly benthic lifestyle. In the Salish Sea ecoregion of North America, sea spider species diversity is poorly characterized, and morphological and molecular data for many species are lacking, limiting our understanding of this group. Using scanning electron microscopy and a range of molecular techniques, we present morphological and molecular phylogenetic analyses of seven species of coastal sea spider from the Salish Sea ecoregion. We redescribe Achelia alaskensis (Cole, 1904), Achelia gracilipes (Cole, 1904), Anoplodactylus erectus (Cole, 1904), Anoplodactylus viridintestinalis (Cole, 1904), and Phoxichilidium quadradentatum (Hilton, 1942). Additionally, we describe two new species of sea spider, Tanystylum kiixin sp. nov. and Callipallene pilosuspedes sp. nov. Finally, to help minimize ambiguities regarding the identification of the species herein, we include a dichotomous key for the pycnogonid fauna of the Salish Sea and West Coast of Vancouver Island.

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.
