  1. Specimen collection depth, species minimum depth, and species maximum depth (in meters) were tested independently. Dentary linear measurements are shown for dorsal fork length (dfl) and ventral fork length (vfl). Total degrees of freedom (df) for each test are shown. Significant p-values below an alpha threshold of 0.05 are marked with two asterisks and bold type, those below the 0.1 alpha threshold are marked with a single asterisk and bold type. Estimated regression coefficient and Akaike information criteria (AIC) are reported for each model. The depth metric with the lowest AIC value for each bone appears in bold type
