Senticaudata


Senticaudata is one of the four suborders of the crustacean order Amphipoda. It includes some 5000 species, which is more than 50% or the currently recognized amphipod diversity.
Senticaudata was split off from the traditional suborder Gammaridea by Lowry & 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. The suborder is defined by a presence of strong apical setae on the 1st and 2nd uropods.
Senticaudata contains much of the world freshwater amphipod diversity, whereas the majority of its species are still marine. Among the major superfamilies included are the Gammaroidea, Crangonyctoidea, Talitroidea and Corophioidea.
