Specimens of Apteronotus brasiliensis from Paraná and São Francisco River basins (Brazil) present snout always moderately elongated, that can be oblique or directed forward or strongly downward. Detailed examination revealed that these head-morphology differences are related to individual variation, not to sex, ontogeny or geographic distribution.
