Anamixidae
Leucothoidae is a family (biology), family of Amphipoda, amphipods. It contains 138 species in 5 genera: *''Anamixis'' Stebbing, 1897 – 21 species *''Leucothoe (crustacean), Leucothoe'' Leach, 1814 – 98 species *''Nepanamixis'' Thomas, 1997 – 4 species *''Paranamixis'' Schellenberg, 1938 – 13 species *''Paraleucothoe'' Stebbing, 1899 – 2 species Males undergo a profound transformation when they reach sexual maturity, turning from the "leucomorph" state to the "anamorph" state. Before this transformation was recognised in 1983, females and immature males were described in the genus ''Leucothoides'' (Leucothoidae), and mature males were described in the genera ''Anamixis'', ''Paranamixis'' and ''Nepanamixis'' (Anamixidae). The genus ''Leucothoides'' may still be used for leucomorphs of species whose anamorph has not yet been identified. References Gammaridea Amphipod families {{Amphipod-stub ...

Gammaridea
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 genus, genera, divided among around 125 family (biology), families. That concept of Gammaridea included almost all fresh water, freshwater amphipods, while most of the members still were marine. The group is however considered paraphyly, paraphyletic, and is under deconstruction by the amphipod taxonomists Jim Lowry, J. Lowry and A. Myers. In 2003 they moved several families from Gammaridea to join members of the former Caprellidea in a new suborder Corophiidea.A. A. Myers & J. K. Lowry (2003).
