Crustacean superorders

Eucarida is a superorder of the Malacostraca, a class of the crustacean subphylum, comprising the decapods, krill, and Angustidontida. They are characterised by having the carapace fused to all thoracic segments, and by the possession of stalked eyes.

The superorder Peracarida is a large group of malacostracan crustaceans, having members in marine, freshwater, and terrestrial habitats. They are chiefly defined by the presence of a marsupium (the "brood pouch"), formed from thin flattened plates (oostegites) borne on the basalmost segments of the legs.

Syncarida is a superorder of crustaceans, comprising the two extant orders Anaspidacea and Bathynellacea, and the extinct order Palaeocaridacea.

Podoplea is a superorder of copepods in the infraclass Neocopepoda that was named by Wilhelm Giesbrecht in 1882. It has a worldwide distribution, with documented appearances in the Arctic, Atlantic, Indian, Pacific, and Southern oceans.
