It grows up to wide, with an H-shaped groove on its back. It is an omnivore and is eaten by crayfish and fish. It was first discovered in Lake Pupuke, near Auckland, and is the only freshwater crab in New Zealand. Distribution ''A. lacustris'' is widespread in south-eastern Australia, from Tasmania to the Murray-Darling basin in South Australia and Victoria. It reaches as far inland as Lake Colac, Victoria. In New Zealand, ''A. lacustris'' is the only freshwater crab, and is found in a variety of habitats, including lakes, slow-flowing streams and larger rivers. It is found from the lower reaches of the Waikato River to Northland, with a notable population in the Oratia Stream near Auckland.

Crayfish
Crayfish are freshwater crustaceans belonging to the clade Astacidea, which also contains lobsters. In some locations, they are also known as crawfish, craydids, crawdaddies, crawdads, freshwater lobsters, mountain lobsters, rock lobsters, mudbugs, baybugs or yabbies. 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 fresh water is running, 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 term "crayfish" is applied to saltwater species in some countries. Terminology The name "crayfish" comes from the Old French word ' ( Modern French '). The word has been modified to "crayfish" by association with "fish" (folk etymology). The largely Amer ...

Northland Region
The Northland Region ( mi, Te Tai Tokerau) is the northernmost of New Zealand's 16 local government regions. New Zealanders sometimes refer to it as the Winterless North because of its mild climate all throughout the year. The main population centre is the city of Whangārei, and the largest town is Kerikeri. At the 2018 New Zealand census, Northland recorded a population growth spurt of 18.1% since the previous 2013 census, placing it as the fastest growing region in New Zealand, ahead of other strong growth regions such as the Bay of Plenty (2nd with 15%) and Waikato (3rd with 13.5%). Geography The Northland Region occupies the northern 80% (265 km) of the 330 km Northland Peninsula, the southernmost part of which is in the Auckland Region. Stretching from a line at which the peninsula narrows to a width of just 15 km a little north of the town of Wellsford, Northland Region extends north to the tip of the Northland Peninsula, covering an area of 13,940&nb ...

Waikato River
The Waikato River is the longest river in New Zealand, running for through the North Island. It rises on the eastern slopes of Mount Ruapehu, joining the Tongariro River system and flowing through Lake Taupō, New Zealand's largest lake. It then drains Taupō at the lake's northeastern edge, creates the Huka Falls, and flows northwest through the Waikato Plains. It empties into the Tasman Sea south of Auckland, at Port Waikato. It gives its name to the Waikato region that surrounds the Waikato Plains. The present course of the river was largely formed about 17,000 years ago. Contributing factors were climate warming, forest being reestablished in the river headwaters and the deepening, rather than widening, of the existing river channel. The channel was gradually eroded as far up river as Piarere, leaving the old Hinuera channel through the Hinuera Gap high and dry. The remains of the old course are seen clearly at Hinuera, where the cliffs mark the ancient river edges. The W ...
