It consists of the following eight genera, including the genera formerly placed in the families Linderiellidae and Polyartemiidae:

It is the only family in the monotypic subclass Branchiura and the order Arguloida, although a second family, Dipteropeltidae, has been proposed.

It was originally described as a subfamily of Branchipodidae by Alpheus Spring Packard in 1883, and elevated to the rank of family by Simon in 1886. Six genera are recognised, in two subfamilies:

The Chthamalidae are a family of chthamaloid barnacles, living entirely in intertidal/subtidal habitats, characterized by a primary shell wall of eight, six, or four plates, lacking imbricating plate whorls, and either membraneous or more rarely calcareous basis. They are not found below immediate subtidal habitats, and more likely are found in the highest tier of shallow-water barnacle fauna. They can be found in the most rigorous wave-washed locations, and some species are found in the surf zone above high tide mark, only receiving water from wave action at high tide. The family includes at

Moinidae is a crustacean family within the order Cladocera. Species within this family are widely occurring, including North America and Africa. In newer classifications, it is sometimes included in the family Daphniidae. Some Moinidae have accidentally been introduced by humans to areas outside of their native range. Genetics study strongly supports division of Moina into two faunistic groups: European-Western Siberian and Eastern Siberian-Far Eastern, with a transitional zone at the Yenisey River basin (Eastern Siberia).

Pollicipedidae is a family of goose barnacles.

Branchipodidae is a family of fairy shrimp, one of eight in the order Anostraca. It contains 35 extant species in five extant genera: Branchipodopsis G. O. Sars, 1898 Branchipus Schaeffer, 1766 Metabranchipus Masi, 1925 Pumilibranchipus Hamer & Brendonck, 1995 Rhinobranchipus Brendonck, 1995
