Schematic representation of anatomical points for the 12 landmarks a defined for morphometric analysis in C. lugubris; (1) tip of the mouth; (2) indentation of the front profile above the snout; (3) insertion of the first dorsal fin; (4) insertion of the second dorsal fin; (5) base of the last dorsal fin ray; (6) end of the anal fin; (7) insertion of the soft anal fin; (8) insertion of the first spine of anal fin; (9) base of the pelvic fin; (10) insertion of the pectoral fin; (11); posterior end of the ocular orbit; (12) anterior end of the ocular orbit. Thin-plate spline representation of significant differences between C. lugubris morphotypes I and II in regard to the combined mean of samples. b Morphotypes I and II of C. lugubris; bar = 5 cm. c Distribution of morphological canonical scores grouped for both morphotypes. d Individuals with negative and positive canonical scores represent morphotypes I and II, respectively. Grouping resulted in 100 % correct classifications
