Freshwater Gammarus spp. are not just herbivores but also predators, feeding on a wide range of food sources. They can even prey on other macroinvertebrates and injured fish. This behavior helps them thrive in changing environments. The traditional view of Gammarus spp. as only herbivores needs to be reevaluated to understand their role as both predators and prey in aquatic ecosystems.
