A new sighting of killer whale, Orcinus orca, in Caribbean inshore waters off Colombia
Bibliographic record
Abstract
Killer whales, Orcinus orca, are known to be one of the most widespread cetaceans, inhabiting all the oceans of the world, but their presence in the Southern Caribbean has been scarcely recorded up to date. An unusual sighting of a killer whale is described for the first time in inshore waters of the Gulf of Morrosquillo. The whale was sighted on 22 March 2015 and it was a solitary individual of unrecognized sex that showed ongoing diving and surfacing behavior at a site 6.3 km from the coast with depths between 20 and 24 m. Its occurrence could be related to favorable environmental and oceanographic conditions and to the potential effect of recent seismic offshore oil and gas operations in the gulf, which may impact a whale’s location and behavior. This report contributes to the scarcity of information about the distribution of O. orca in the Caribbean Sea along the coast of Colombia.

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.
