The three species of kākāriki, or New Zealand parakeets, are the most common species of parakeets in the genus Cyanoramphus, family Psittacidae. The birds' Māori name, which is the most commonly used, means "small parrot". The etymology is: from kākā, parrot + riki, small. The word is also used to refer to the colour green because of the birds' predominantly green plumage. The patches of red on the birds' rumps are, according to legend, the blood of the demigod Tāwhaki. The three species on mainland New Zealand are the yellow-crowned parakeet, the red-crowned parakeet, or red-fronted parakeet, and the critically endangered Malherbe's parakeet or orange-fronted parakeet.
The New Zealand pea crab, Nepinnotheres novaezelandiae, is a small, parasitic crab that lives most commonly inside New Zealand green-lipped mussels. Adult females are about the size and shape of a pea, while adult males are smaller and flatter. Adult New Zealand pea crabs are completely reliant on their host mussel for shelter and food, which it steals from the mussel's gills. The New Zealand pea crab is found throughout New Zealand and can infect up to 70% of natural populations. These crabs are of concern to green-lipped mussel aquaculture because they reduce the size and growth of mussels, although infected mussels can be harvested and consumed.
Pinnotheres is a genus of crabs, including the pea crab. Many species formerly in Pinnotheres have been placed in new genera, such as Zaops ostreus, the oyster crab and Nepinnotheres novaezelandiae, the New Zealand pea crab. The species currently recognised in the genus Pinnotheres are:
The black stilt or kakī (Māori) is a wading bird found in New Zealand. It is one of the world's rarest birds, with 169 adults surviving in the wild as of May 2020. Adult kakī have distinctive black plumage, long pink legs, and a long thin black bill. Black stilts largely breed in the Mackenzie Basin in the South Island, and are threatened by introduced feral cats, ferrets, and hedgehogs as well as habitat degradation from hydroelectric dams, agriculture, and invasive weeds.
The pink cusk-eel, Genypterus blacodes, is a demersal species of cusk-eel found in the oceans around southern Australia, Chile, Brazil, and around New Zealand except the east coast of Northland, in depths of 22 to 1,000 metres. Their length is up to 200 centimetres, and they live for up to 30 years. Their maximum weight is 25 kilograms.
The blue grenadier is a merluccid hake of the family Merlucciidae found around southern Australia and New Zealand, as well as off both the Atlantic and Pacific coasts of South America from Peru to Brazil at depths of between 10 and 1,000 m. It feeds in midwater on small squids, crustaceans, and fish. Its length is between 60 and 120 cm. It is a slender, silvery fish similar in appearance to the gemfish. The meat of the fish is white and almost always sold in fillets; culinarily it is considered a whitefish.
The red-crowned parakeet, also known as red-fronted parakeet and by its Māori name of kākāriki, is a small parrot from New Zealand. It is characterised by its bright green plumage and the red pattern on its head. This versatile bird can feed on a variety food items and can be found in many habitat types. It used to be classified as near threatened as invasive predators had pushed it out of its historical range but it is now at least concern. This species used to occupy the entire island, but is now confined to only a few areas on the mainland and some offshore islands.
Crapatalus novaezelandiae, is a species of southern sandfish endemic to the Pacific waters around New Zealand. It occurs in shallow sandy areas, particularly harbours and estuaries. Its length is up to 45 cm.
The pea crab, Pinnotheres pisum, is a small crab in the family Pinnotheridae that lives as a parasite in oysters, clams, mussels, and other species of bivalves.
The pie crust crab, is a species of crab found around New Zealand and south-eastern Australia.
The New Zealand quail, or koreke in Māori, is an extinct quail species endemic to New Zealand. The male and female were similar, except the female was lighter. The first scientist to describe it was Sir Joseph Banks when he visited New Zealand on James Cook's first voyage. Terrestrial and temperate, this species inhabited lowland tussock grassland and open fernlands. The first specimen to be obtained by a European was collected in 1827 by Jean René Constant Quoy and Joseph Paul Gaimard on Dumont D'Urville's voyage.
The New Zealand bittern is an extinct and enigmatic species of heron in the family Ardeidae. It was endemic to New Zealand and was last recorded alive in the 1890s.
Pecten novaezelandiae, common name the New Zealand scallop, is a bivalve mollusc of the family Pectinidae, the scallops. Its name is sometimes found misspelt as Pecten novaezealandiae.
Celmisia spectabilis is one of the more widespread species in the mountainous areas of New Zealand, where it is commonly known as the cotton daisy. Belonging to the family Asteraceae, this species has leathery leaves that are ovate to lanceolate or narrowly oblong, and can reach 30 cm long. They have a shiny, green upper surface, with prominent parallel grooves, but their undersides are densely covered in soft, whitish or buff-coloured hairs. The leaf bases overlap and compact to form a stout pseudostem. Plants can form mats up to 2 m across.
Triplosarus novaezelandiae is a species of beetles in the family Carabidae, the only species in the genus Triplosarus. It is endemic to New Zealand.
Melangyna novaezelandiae is a hoverfly endemic to New Zealand. It is a generalized pollinator of a large range of plants that are both native and exotic to the New Zealand flora. M. novaezelandiae is widespread throughout New Zealand, including in agricultural environments. The larvae of this species feeds on other arthropods and may have uses as a biocontrol agent.
Anguillicoloides novaezelandiae is a parasitic nematode worm that lives in the swimbladders of eels, particularly Anguilla australiensis, Anguilla anguilla and Anguilla dieffenbachii. Specimens have been located in Italy and New Zealand. The species is most similar to A. Australiensis. However, it differs from the latter species in the shape of the head end which is bulbously inflated, almost spherical, and followed by a marked neck constriction in A. Australiensis, whereas it is only slightly expanded in A. novaezelandiae. Also, the anterior ovary in A. australiensis females extends anteriorly to about the mid-length of the oesophagus, while it does not reach the end of the oesophagus in A. novaezelandiae. Both species differ in size and form. While the body of A. australiensis is long and relatively slender, that of A. novaezelandiae is much shorter and wider. The shape of the posterior end of the female body is different in these two species.
