Researchers from the University of Liege reveal piranhas communicate with sound, including bark-like snaps, croaks, and drumbeat pulses. The findings indicate that these freshwater predators have a social acoustic life that shapes interactions in their riverine homes, not just moments of feeding. The study suggests piranhas contribute to the soundscape of their environments in ways that were previously overlooked, adding depth to our understanding of freshwater behavior.
