BIORESUSPENSION BEHAVIORS OF THE GOBIID, <i>VALENCIENNEA PUELLARIS,</i> AND THE BIOGENIC SEDIMENTARY STRUCTURES IT PRODUCES
Bibliographic record
Abstract
ABSTRACT Biologically mediated fabrics are disturbed sediment by organisms that resemble primary physical structures. In this aquaria-based study, the sand-sifting goby, Valenciennea puellaris, produced biogenic sedimentary structures resembling planar lamina and ripple cross lamina with grain sizes ranging from fine sand to gravel. Valenciennea puellaris moved and re-deposited fine- and coarse sand and gravel used in this study, but dug only in fine- to coarse sand. Gravel-sized particles were too large to pass through its gills and therefore the goby moved them individually. Through the bioresuspension behaviors of feeding, digging, and resting, the V. puellaris produces Piscichnus-like craters and moves about nine mouthfuls of sediment a minute, i.e., 0.18 cm3. The biogenic fabrics produced by V. puellaris in this study are similar to primary sedimentary fabrics produced by hydrologic flow. Similar behaviors and feeding styles are widespread and found in larger fish and marine mammals. While V. puellaris has only been around since the Eocene, burrowing Actinopterygians date back to 400 Ma, suggesting that similar biogenic sedimentary structures may have a long history in the geological record.

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.
