Type locality. Anvers Island (Antarctic Peninsula). Bathymetric distribution. 5–113 m. Substrate. Soft bottom. Geographical distribution. ANTARCTICA:Antarctic Peninsula, Bellingshausen Sea. SUBANTARCTICA: Kerguelen Islands, Macquarie Islands. SCOTIA ARC: South Georgia, South Orkney Islands, South Shetland Islands. SOUTH AMERICA: -. Remarks. In contrast to the following species, A. charcoti was never found in the intertidal, but occupied depths between 15 and 100 m. This common species was regularly colonised by polyps of the hydrozoan Monobrachium Mereschkowsky, 1877. Altenaeum charcoti is easily confused with A. narchii, with which it often occurs sympatrically. The somewhat more bulbous shape, the shorter main teeth of the left valve, and the absence of the ligament plate clearly distinguish this species from the following species. The species is already known from the Maxwell and Admiralty Bays. The species is a free-living, shallow-burrower, with a predominantly deposit-feeding habit (Passos et al. 2005). References.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
