Spinicaudata

Cyzicidae is a family of crustaceans in the order Spinicaudata. They are distinguished from the family Leptestheriidae by the absence of a rostral spine. Some members of Cyzicidae are known to burrow through mud, leading to speculation that they may be filter feeders, but Martin reports that their mouthparts are indistinguishable from Leptestheriidae, which are believed to be grazers.

Limnadiidae is a family of crustaceans in the order Spinicaudata that live in seasonal wetlands, inland saline pools and lakes. They are found on all the world's continents except Antarctica, and are distinguished from other families in the same order by the fact that the cephalic fornicies do not extend forwards. The family contains eight extant genera: Afrolimnadia Rogers et al., 2012 Calalimnadia Rabet & Rogers, 2012 Eulimnadia Packard, 1874 Imnadia Hertzog, 1935 Limnadia Brongniart, 1820 Limnadopsis Spencer & Hall, 1896 Metalimnadia Mattox, 1952 Paralimnadia Sars, 1896
