Gammarinae

Gammarinae is a subfamily of amphipods within the family Gammaridae. These small crustaceans are typically found in freshwater environments, though some species can inhabit brackish or marine waters. Members of Gammarinae are characterized by their laterally compressed bodies and a series of pairs of walking legs. They are detritivores and scavengers, playing an important role in the decomposition of organic matter in aquatic ecosystems. Many species are benthic, living on the bottom of lakes, rivers, and streams. Gammarinae are often preyed upon by larger aquatic animals, serving as a crucial link in the food web. The subfamily encompasses a diverse range of species, with many yet to be fully described or studied. Their distribution is widespread across various continents. Research into Gammarinae contributes to our understanding of freshwater invertebrate ecology and biodiversity.
