Amphipods are malacostracan crustaceans (Phylum Arthropoda) with three major (Caprellidea, Hyperiidea and Gammaridea) and one minor (Ingolfiellidea) suborder. They are a diverse group and are common in aquatic ecosystems throughout the world being found in marine, brackish, and freshwater environments. Their body is divided into 13 segments, consisting of a head, a thorax and an abdomen. There are two characteristic body forms, those of the Gammaridea and those of the Caprellidea. The gammarids are compact and flattened from side to side, whereas the caprellids have slender and elongated bodies with long limbs. Many of the amphipods in NEMESIS have been introduced as part of the fouling community on recreational boats, commercial ships and aquaculture imports. The impacts of exotic amphipods are varied, with many having no reported impact, but some species can reach extraordinary densities which may negatively affect aquaculture operations, displace native amphipod species, or alter the feeding habits of fish.
