South America | Red-bellied piranhas communicate with each other through aggressive behaviors (biting, chasing, fighting) and through sounds made by their sonic muscles. While they are hunting prey, these sharp-toothed fish create sounds based on the intensity of the pursuit. The more vigorous, the louder and more threatening they sound. Don’t be fooled by the myths, though, these fish are typically timid scavengers, like vultures. . . . . . . . #animalsofinstagram #animalplanet #animaloftheday #wild #wildlife #outdoors #animals #wildanimals #conservation #nature #animallovers #instanature #wildgeography #wildlifeonearth #southamerica #piranha #fish
