Calliopius is a genus of amphipods in the family Calliopiidae. There are about nine described species in Calliopius. [1] [2] [3]
These nine species belong to the genus Calliopius:
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 terrestrial animals and sandhoppers such as Talitrus saltator.
Monoporeia affinis, formerly referred to as Pontoporeia affinis, is a small, yellowish benthic amphipod living in the Baltic Sea, the Arctic Sea and the lakes of the Nordic Countries.
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.
Corophiidae is a family of amphipods, containing the following genera:
Hyalidae is a family of amphipods, containing 12 genera in two unequal subfamilies:
Pardaliscidae is a family of amphipods, whose members typically inhabit the deepest parts of ocean basins. It contains the following genera:
Anisogammaridae is a family of small benthic amphipods, endemic to the northern part of the Pacific rim. The family contains the following genera:
Talitridae is a family of amphipods. Terrestrial species are often referred to as landhoppers and beach dwellers are called sandhoppers or sand fleas. The name sand flea is misleading, though, because these talitrid amphipods do not bite people.
Allorchestes is a genus of amphipods with relatively small gnathopods, in the family Dogielinotidae; it contains the following species:
Corophium is a genus of the amphipod family Corophiidae. Formerly a much larger genus, many species have been transferred to segregate genera such as Monocorophium and Crassicorophium.
Crangonyctidae is a family of cave-dwelling freshwater amphipod crustaceans. It contains the following genera:
Crassicorophium is a genus of amphipod crustaceans, comprising three species:
Apocorophium is a genus of amphipod crustaceans, comprising the following species:
Amphiporeia is a genus of amphipods in the family Bathyporeiidae. There are at least three described species in Amphiporeia.
Stygobromus russelli, known generally as the russell stygobromid or Russell's cave amphipod, is a species of amphipod in the family Crangonyctidae. It is found in North America.
Arcitalitrus is a genus of beach hoppers in the family Talitridae. There are about nine described species in Arcitalitrus.
Americorchestia is a genus of beach hoppers in the family Talitridae. There are about five described species in Americorchestia.
Uhlorchestia is a genus of beach hoppers in the family Talitridae. There are at least two described species in Uhlorchestia.
Haustorius is a genus of amphipods in the family Haustoriidae. There are about six described species in Haustorius.
Traskorchestia is a genus of beach hoppers in the family Talitridae. There are at least three described species in Traskorchestia.
