Senticaudata is one of the six suborders of the crustacean order Amphipoda (the group of scuds or sideswimmers). It includes some 6000 species, which is more than 50% of the currently recognized amphipod diversity.[2]

Senticaudata was split off from the traditional suborder Gammaridea by James K. Lowry and Alan A. Myers in 2013, as a part of a process of reorganising the higher taxonomy of amphipods. It now also encompasses the previously recognized Caprellidea and Corophiidea.[1] The suborder is defined by the presence of strong apical setae on the 1st and 2nd uropods.[1]

Senticaudata contains much of the world's freshwater amphipod diversity, though the majority of its species are marine. It is currently subdivided into the six infraorders Bogidiellida, Carangoliopsida, Corophiida, Gammarida, Hadziida, and Talitrida.[3]

Infraorders

Classification based on WoRMS.[3] Families marked with "M" are monotypic (containing only one genus).

Bogidiellida Hertzog, 1936

Superfamilies:

Carangoliopsida Bousfield, 1977

Superfamilies:

Corophiida Leach, 1814 (sensu Lowry & Myers, 2013)

This infraorder contains the families of skeleton shrimp and whale lice.[4] The whole group was previously treated as its own suborder, Corophiidea, before being subsumed into Senticaudata.[5][6]

Superfamilies:

Gammarida Latreille, 1802

This infraorder contains the family of scuds, along with the families endemic to Lake Baikal.

Superfamilies:

Hadziida S. Karaman, 1943

Superfamilies:

Talitrida Rafinesque, 1815

This infraorder contains the family of terrestrial land- or sandhoppers.
