Eurythenes is a genus of marine amphipods in the family Eurytheneidae.
Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods range in size from 1 to 340 millimetres and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as Talitrus saltator.
Gammaridea is one of the suborders of the order Amphipoda, comprising small, shrimp-like crustaceans. Until recently, in a traditional classification, it encompassed about 7,275 (92%) of the 7,900 species of amphipods described by then, in approximately 1,000 genera, divided among around 125 families. That concept of Gammaridea included almost all freshwater amphipods, while most of the members still were marine.
Epimeriidae is a family of relatively large amphipods found in cold oceans around the world.
Anisogammaridae is a family of small benthic amphipods, endemic to the northern part of the Pacific rim. The family contains the following genera:
Lysianassidae is a family of marine amphipods, containing the following genera:
Bathyporeia is a genus of amphipods in the family Pontoporeiidae, containing the following species:
Amaryllididae is a family of marine benthic amphipods found throughout the southern hemisphere. These smooth, laterally compressed amphipods can be distinguished by the accessory setal row of the mandible having a distal tuft. It contains the following genera:
Pontogeneiidae is a family of amphipod crustaceans, containing the following genera:
Alicellidae is a family of amphipod crustaceans, which live as scavengers in the deep sea, often in association with hydrothermal vents. The family includes the following genera:
Themisto is a genus of marine amphipods in the family Hyperiidae. Their distribution is cosmopolitan.
Bathyporeiidae is a family of amphipods in the order Amphipoda. There are two genera in Bathyporeiidae:
Gammaroidea is a superfamily of amphipods in the order Amphipoda.
Epimeria is a genus of amphipods in the family Epimeriidae. There are more than 80 described species in Epimeria.
Eurythenes gryllus is a relatively large species of amphipod found worldwide in cold, deep oceans. This widespread and often common species is benthic and lives at depths of 550–7,800 m (1,800–25,600 ft).
Eurythenes plasticus is a species of amphipod of the genus Eurythenes, first described in 2020. It was named in reference to the PET plastic found in its stomach, after researchers wanted to highlight the impact of plastic pollution.
Eurythenes thurstoni is a species of amphipod of the genus Eurythenes. It was first described in 2004 and named after Mike Thurston, a marine biologist specialising in deep-sea amphipods.
Eurythenes obesus is a species of amphipod of the genus Eurythenes. It was first described in 1905 by Édouard Chevreux.
Eusirus is a genus of amphipods belonging to the family Eusiridae.
Eurythenes atacamensis is a species of amphipod restricted to the Peru-Chile ocean trench.
