Taxonomy of Euretidae (Porifera, Hexactinellida, Hexactinosida) of Campos Basin, southwestern Atlantic, with a description of a new species
Bibliographic record
Abstract
Abstract Fourteen species of hexactinellid sponges have been known from the southwestern Atlantic, 11 of which belong to the subclass Hexasterophora. Among these, only two belong to Hexactinosida Schrammen, 1903, namely Aphrocallistes beatrix Gray, 1858, Dactylocalyx pumiceus Stutchbury, 1841. The present study increases the number of southwestern Atlantic Hexasterophora to 13 species, adding two additional Hexactinosida, namely Chonelasma choanoides Schulze & Kirkpatrick, 1910 and Eurete atlantica sp. nov. The latter species is the first record of Eurete for the Atlantic Ocean, differing from the remaining 11 known species most conspicuously by the heavy spination of its pentactines.
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.
