Peracarida

The peracarids are a large group of malacostracan crustaceans recognisable by the possession of the lacinia mobilis (a blade like process on the mandible), and direct development of young, which are brooded in a pouch formed by lamellar outgrowths of the bases of the thoracic limbs (with the exception of the thermosbaenaceans, which brood their eggs under the carapace). In most cases, peracarids are minute, not exceeding 10 mm in length (many individual exceptions exist of course, such as the giant deep-sea isopod, Bathynomus). Despite their small size, however, peracarids are highly speciose and abundant in most habitats. Of the nine generally recognised per-acarid orders, the most important on the GBR are the Mysidacea, Cumacea, Tanaidacea, Isopoda, and Amphipoda.
