Fauna of Australia predators which include abalone and rock lobster. Introduced invertebrate pests include the Asian mussel, New Zealand green-lipped mussel, black-striped mussel and the Northern Pacific seastar, all of which displace native shellfish. There are many unique marine crustaceans in Australian waters. The best-known class, to which all the edible species of crustacean belong, is Malacostraca. The warm waters of northern Australia are home to many species of decapod crustaceans, including crabs, false crabs, hermit crabs, lobsters, shrimps, and prawns. The peracarids, including the amphipods and isopods, are more diverse in the colder waters of southern Australia. Less-well-known marine groups include the
Great-billed hermit of eastern Brazil is sometimes considered a separate species: Margaretta's Hermit ("P. margarettae").

A satisfactory taxonomic treatment of the entire "P. longirostris/P. superciliosus/P. malaris" group is still lacking
