Ellobiopsids of the Genus <i>Thalassomyces</i> are Alveolates
Bibliographic record
Abstract
Ellobiopsids are multinucleate protist parasites of aquatic crustaceans that possess a nutrient absorbing 'root' inside the host and reproductive structures that protrude through the carapace. Ellobiopsids have variously been affiliated with fungi, 'colorless algae', and dinoflagellates, although no morphological character has been identified that definitively allies them with any particular eukaryotic lineage. The arrangement of the trailing and circumferential flagella of the rarely observed bi-flagellated 'zoospore' is reminiscent of dinoflagellate flagellation, but a well-organized 'dinokaryotic nucleus' has never been observed. Using small subunit ribosomal RNA gene sequences from two species of Thalassomyces, phylogenetic analyses robustly place these ellobiopsid species among the alveolates (ciliates, apicomplexans, dinoflagellates and relatives) though without a clear affiliation to any established alveolate lineage. Our trees demonstrate that Thalassomyces fall within a dinoflagellate + apicomplexa + Perkinsidae + "marine alveolate group 1" clade, clustering most closely with dinoflagellates. However, the poor statistical support for branches within this region indicates that additional data will be needed to resolve relationships among these taxa.

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.
