In Australia what name is given to a crayfish?
Crayfish Range in Australia. Crayfish Crayfish, also known as crawfish, crawdads, crawlfish, crawldads, freshwater lobsters, mountain lobsters, mudbugs or yabbies, are freshwater crustaceans resembling small lobsters (to which they are related). Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills. Some species are found in brooks and streams where there is running fresh water, while others thrive in swamps, ditches, and paddy fields. Most crayfish cannot tolerate polluted water, although some species such as "Procambarus clarkii" are hardier. Crayfish feed on animals and plants, either living or decomposing, and detritus. The name "crayfish" comes from
Crayfish the southern Murray-Darling basin. In New Zealand, two species of "Paranephrops" are endemic, and are known by the Māori name "". Fossil records of crayfish older than 30 million years are rare, but fossilised burrows have been found from strata as old as the late Palaeozoic or early Mesozoic. The oldest records of the Parastacidae are in Australia, and are 115 million years old. Some crayfish suffer from a disease called crayfish plague, caused by the North American water mould "Aphanomyces astaci" which was transmitted to Europe when North American species of crayfish were introduced there.
