- This statistical procedure was carried out for data analyzed at each level in the lateral line system (canal, canal portion, canal segment; see text for additional information) in the supraorbital (SO) and mandibular (MD) canals for which ANCOVAs demonstrated significantly different slopes between species. Numerical values represent the fish size (mm SL) above which Aulonocara has wider canal diameters, longer neuromast lengths, and/or wider neuromast widths, except as noted. *fish size (mm SL) below which the variable has a higher value in Aulonocara than in Tramitichromis. **fish size (mm SL) above which the variable has a higher value in Tramitichromis than in Aulonocara. N/A indicates that the slopes comparing trends for Aulonocara and Tramitichromis were not statistically different, so the Johnson-Neyman procedure was not used.
