From: Hearing capacities and morphology of the auditory system in Serrasalmidae (Teleostei: Otophysi)
Hearing curves of minimum and maximum sensitivity for herbivorous (Piaractus brachypomus, Metynnis lippincottianus, Myloplus rubripinnis and Myleus schomburgkii) and carnivorous species (Serrasalmus elongatus, Serrasalmus spilopleura, Pygocentrus nattereri and Pygocentrus piraya). The area between the grey lines contains hearing thresholds of herbivorous species. The area between the black lines contains hearing thresholds of carnivorous species. The shaded area corresponds to the range of hearing thresholds overlapping between the two groups. Hearing curves of minimum sensitivity for herbivorous species (dashed grey line), maximum sensitivity for herbivorous species (solid grey line), minimum sensitivity for carnivorous species (dashed black line), maximum sensitivity for carnivorous species (solid black line).
