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
Stripe-throated hermit been considered a subspecies of the little hermit ("P. longuemareus"), but morphological data suggest it may be closer to the grey-chinned hermit ("P. griseolaris"). At present most, if not all, major authorities accept the split (SACC, the Clements check list, the Howard & Moore check list, etc.). It has been suggested that the mainly Central American taxon "saturatus", which typically is considered a subspecies of "P. striigularis", may deserve species status, in which case it would become the dusky hermit or Boucard's hermit ("P. saturatus"). The taxon "adolphi" is considered a junior synonym of "saturatus" by most authorities. It occurs
