    Paramesodopsis rufa - Mysid 
    (Edgar, 1997)
    These are moderately sized crustaceans (length to 14 mm) which are an important source of food for seahorses and other Sygnathids. They are generally found in swarms just above the seabed and are often mistaken for juvenile fish. Many species feed on fine particles produced by decomposing kelp and seagrass. This makes them an important link between the sea floor and the open water food webs. The most common species of mysid found around Tasmania is Paramesodopsis rufa, which grows to 14 mm and is found on moderately exposed reef, in Victoria and around Tasmania. This species eats small crustaceans in addition to plant material.

    ISOPODS

    Zuzara venosa - Isopod
    (Edgar, 1997)
    These crustaceans are similar to amphipods however they are flattened from top to bottom. They can grow up to 20 mm in length and can adapt to many habitats. Many species live in freshwater, among leaf litter on land, as parasites on fish, as borers of wood and on the sea floor. They also include 'sea lice' which congregate on dead animal material. Several species (Zuzara venosa and Ligia australiensis) are found in the intertidal zone and shallow water, under rocks and in crevices.
