common intertidal amphipod

<em>Gammarus locusta</em>, commonly known as the common intertidal amphipod, is a crustacean in the family Gammaridae. Its conservation status has not been formally evaluated by the IUCN. The species is recorded from Denmark, Norway, Portugal, and Sweden, indicating a distribution along the northeastern Atlantic coast of Europe. It typically inhabits intertidal and shallow subtidal marine and estuarine environments, where it is found among algae, under rocks, and in sediments. Gammarus amphipods are ecologically important as detritivores and as prey for shorebirds, fish, and other invertebrates in coastal food webs. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.
