Table 2 in A redescription of Astyanax gymnodontus (Eigenmann, 1911), new combination, a polymorphic characid fish from the rio Iguaçu basin, Brazil

Table 2. The ranges of standard length (SL) and ratios suggested by canonical discriminant analysis are shown for the three morphotypes of Astyanax gymnodontus. Abbreviations of truss measurements are shown according to Table 1, and traditional measurements are: BOD, body depth; CPD, caudal-peduncle depth; CPL, caudal-peduncle length; DFL, dorsal-fin length; HL, head length; IOD, interorbital distance; JW, jaw width; OD, orbital diameter; PDL, predorsal length; and SNL, snout length. Bolded ratios correspond to those responsible for a faint separation between morphotypes in axis 2 of the principal components analysis shown in Fig. 2.
