Rhepoxynius is a genus of amphipod. [1] [2] It is found along the east and west coasts of North America. [3]
The genus Rhepoxynius contains the following species:
The name Rhepoxynius comes from rhepo, meaning "slope", and oxyno, meaning "sharpen". [2]
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 and Arcitalitrus sylvaticus.
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.
Bateidae is a family of amphipod crustaceans, comprising the single genus Batea, which in turn contains thirteen species:
Pardaliscidae is a family of amphipods, whose members typically inhabit the deepest parts of ocean basins. It contains the following genera:
Allorchestes is a genus of amphipods with relatively small gnathopods, in the family Dogielinotidae; it contains the following species:
Orchestia is a genus of amphipods in the family Talitridae. Species in Orchestia are parasitized by the Filozoan species Txikispora philomaios.
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.
Carl Peter Holbøll (1795–1856) was an officer in the Danish Royal Navy, Greenland colonial officer and explorer of the Greenlandic fauna.
Cyproideidae is a family of amphipod crustaceans. Eighteen genera and 43 species have been described as of 2009. They mostly occur mostly in the Southern Hemisphere, where they form associations with corals, sponges, crinoids and hydroids.
Photis is a genus of amphipod crustaceans, containing the following species:
Iphimedia is a genus of amphipods which belongs to the family Iphimediidae in the arthropod group Amphipoda. It is the only genus of the family to have species which live in tropical waters. All other genera of the family are only found in cold or deep oceans.
Urothoe is a genus of very small marine amphipod crustaceans in the family Urothoidae. Members of the genus are found worldwide.
Pontogeneia is a genus of amphipods in the family Pontogeneiidae. It contains the following species:
Nototropis is a genus of amphipod crustaceans, in the family, Atylidae, and was first described by Achille Costa in 1853.
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:
Martensia martensi is a species of amphipod crustacean, and the only species in the genus Martensia. It occurs in waters around Svalbard at depths of 37–95 metres (121–312 ft).
Pseudamphithoides incurvaria is a species of amphipod crustacean in the family Ampithoidae. It is native to shallow water in the tropical western Atlantic Ocean where it creates a home for itself from fragments of the algae on which it feeds. This seaweed contains certain chemicals that are distasteful and protect it from predatory fish.
Austropheonoides is a genus of amphipods in the Cyproideidae family, and was first described in 1972 by Jerry Laurens Barnard
Apohyale is a genus of amphipod in the family Hyalidae, first described by E.L. Bousfield and E.A. Hendrycks in 2002, The type species by original designation is Allorchestes pugettensis Dana, 1853, currently (2023) accepted as Apohyale pugettensis.
