Gammaridae is a family of amphipods. In North America they are included among the folk taxonomic category of "scuds", and otherwise gammarids is usually used as a common name.
They have a wide distribution, centered on Eurasia, and are euryhaline as a lineage, inhabiting fresh to marine waters.
Systematics The Gammaridae were for a long time used as a "wastebin taxon", which included numerous genera of gammaridean amphipods that since then have been removed to their own families, such as the Anisogammaridae, Melitidae and Niphargidae.
