Anaspidaceans belong to an ancient group of basal eumalacostracans known as the Syncarida. Syncaridan fossils are known from freshwater Carboniferous and Permian deposits. The approximately 70 extant anaspidacean species occur in southern South America, New Zealand and southern Australia, but the majority occur in Tasmania and a few sites in southern Australia.

Anaspidaceans are considered to be omnivores. They live in freshwater mountain streams, small ponds, crayfish burrows or among sphagnum mosses. One group, the stygocarids, are blind.

Anaspidaceans differ from other malacostracans in having a distinct peduncle and flagellum on antenna 1, no carapace and the females shed their eggs externally.
