Feeding habits and habitat use of three sympatric piranha species in the Pantanal wetland of Brazil

We investigated the diet and habitat use of sympatric piranha species (Serrasalmus maculatus, S. marginatus, Pygocentrus nattereri) in three rivers and three lagoons of the Miranda River basin in the Southern Pantanal, Brazil. The three species showed differences in size, weight, abundance, and diet...
