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 brood pouch, or marsupium, formed from thin flattened plates (oostegites) borne on the basalmost segments of the legs [2] Other characters which unite the group are the possession of a single pair of maxillipeds (rarely 2–3), of mandibles with an articulated accessory process between the molar and incisor teeth in the adults (called the lacinia mobilis), and of a carapace which is often reduced in size and is not fused with the posterior thoracic somites.[3] The young hatch at a post-larval, prejuvenile stage called a manca which lacks the last pair of legs.[3]
The following orders are included:[4]
- Amphipoda Latreille, 1816
- Cumacea Krøyer, 1846
- Isopoda Latreille, 1817
- Lophogastrida G. O. Sars, 1870
- Mictacea Bowman, Garner, Hessler, Iliffe & Sanders, 1985
- Mysida A. H. Haworth, 1825
- Pygocephalomorpha Beurlen, 1930
- Spelaeogriphacea Gordon, 1957
- Stygiomysida Tchindonova, 1981
- Tanaidacea Dana, 1849
- Thermosbaenacea Monod, 1927
