Abstract
The recent collection (2009) of an American talon crab, Euchirograpsus americanus A. Milne-Edwards, 1880, in the Bay of Fundy, Canada has expanded the known distribution of this enigmatic plagusiid crab species typically found in subtropical and tropical waters of the Gulf of Mexico, Caribbean, and Carolinas. Although historical records are limited, they document a northward range expansion of the species with occurrences off North Carolina in 1962, Delaware in 1979, and further to New Jersey in 1981, which would discount these northerly records as independent, accidental introductions. The present exclusive record of the talon crab in Canadian waters is also from the shallowest (6.3 m) and coldest waters (8.3°C) that the species has thus far been documented in. The literature, until now, indicated an affinity for sandy or rocky bottom between 31 and 510 m depth at temperatures of 11-24°C. While establishment of the species in the region remains uncertain, the present record is perhaps indicative of large-scale processes, such as climate change, that are altering species distributions.

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 it
