River otters generally select for benthic, slow-moving aquatic prey available in high abundance, suggesting that they rely on a "risk averse" foraging strategy that focuses on consistently catchable prey rather than targeting species that might provide a greater energetic reward per capture.
“River otters generally select for benthic, slow‐moving aquatic prey available in high abundance (Ryder 1955; Cote et al. 2008; Day et al. 2015), suggesting that they rely on a “risk averse” foraging strategy that focuses on consistently catchable prey rather than targeting species that might provide a greater energetic reward per capture (Pyke 1984).”

In primary freshwater habitats, the primary determinant of prey selection is almost always movement speed, with river otters selecting for slower species that are easier to capture and restrain.
“In these habitats, however, the primary determinant of prey selection is almost always movement speed, with river otters selecting for slower species that are easier to capture and restrain (Ryder 1955; Day et al. 2015).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
