  1. Analysis was carried out for supraorbital (SO) and mandibular (MD) canals together (combined) or individually in Tramitichromis and Aulonocara. SL = standard length (fish size) in mm. Significance level = P <0.05. All data were normally distributed. See Figures 10 and 12 and Tables 1 and 5 for results of ANCOVAs. CD, canal diameter; NML, neuromast length; NMW, neuromast width.
