Amphipoda

Order of malacostracan crustaceans

Amphipoda is an order of malacostracan crustaceans characterized by sessile eyes and the absence of a carapace. Amphipods comprise more than 10,700 species, are found in almost all aquatic environments, from fresh water to the deepest parts of the ocean, as well as in terrestrial environments, and generally have laterally compressed bodies. Most amphipods are marine, although around 20% of species inhabit fresh water and other non-marine environments, while the family Talitridae includes terrestrial landhoppers as well as semi-terrestrial and marine species.
