Tuatara are reptiles endemic to New Zealand. Despite their close resemblance to lizards, they are part of a distinct lineage, the order Rhynchocephalia. The name tuatara is derived from the Māori language and means "peaks on the back". The single extant species of tuatara is the only surviving member of its order. Rhynchocephalus originated during the Triassic, reached worldwide distribution and peak diversity during the Jurassic and, with the exception of tuatara, were extinct by 60 million years ago. Their closest living relatives are squamates. For this reason, tuatara are of interest in the study of the evolution of lizards and snakes, and for the reconstruction of the appearance and habits of the earliest diapsids, a group of amniote tetrapods that also includes dinosaurs and crocodilians.
Moa were nine species of now-extinct flightless birds endemic to New Zealand. The two largest species, Dinornis robustus and Dinornis novaezelandiae, reached about 3.6 m (12 ft) in height with neck outstretched, and weighed about 230 kg (510 lb) while the smallest, the bush moa, was around the size of a turkey. Estimates of the moa population when Polynesians settled New Zealand circa 1300 vary between 58,000 and approximately 2.5 million.
Hector's beaked whale, is a small mesoplodont living in the Southern Hemisphere. This whale is named after Sir James Hector, a founder of the colonial museum in Wellington, New Zealand. The species has rarely been seen in the wild.
The red-billed gull, also known as tarāpunga and once also known as the mackerel gull, is a native of New Zealand, being found throughout the country and on outlying islands including the Chatham Islands and subantarctic islands. It was formerly considered a separate species but is now usually treated as a subspecies of the silver gull.
The grey teal is a dabbling duck found in open wetlands in Australia and New Zealand.
The kelp gull, also known as the Dominican gull, is a gull that breeds on coasts and islands through much of the Southern Hemisphere. The nominate L. d. dominicanus is the subspecies found around South America, parts of Australia, and New Zealand. L. d. vetula is a subspecies occurring around Southern Africa.
Jasus edwardsii, the southern rock lobster, red rock lobster, or spiny rock lobster, is a species of spiny lobster found throughout coastal waters of southern Australia and New Zealand including the Chatham Islands. It is commonly called crayfish in Australia and New Zealand and kōura in Māori. They resemble lobsters, but lack the large characteristic pincers on the first pair of walking legs.
The New Zealand bellbird, also known by its Māori names korimako, makomako, and kōmako, is a passerine bird endemic to New Zealand. It has greenish colouration and is the only living member of the genus Anthornis. The bellbird forms a significant component of the famed New Zealand dawn chorus of bird song that was much noted by early European settlers. The explorer Captain Cook wrote of its song "it seemed to be like small bells most exquisitely tuned". Its bell-like song is sometimes confused with that of the tūī. The species is common across much of New Zealand and its offshore islands as well as the Auckland Islands.
Scylla serrata is an ecologically important species of crab found in the estuaries and mangroves of Africa, Australasia, and Asia. In their most common forms, their shell colours vary from a deep, mottled green to very dark brown.
The Galaxiidae are a family of mostly small freshwater fish in the Southern Hemisphere. The majority live in Southern Australia or New Zealand, but some are found in South Africa, southern South America, Lord Howe Island, New Caledonia, and the Falkland Islands. One galaxiid species, the common galaxias, is probably the most widely naturally distributed freshwater fish in the Southern Hemisphere. They are coolwater species, found in temperate latitudes, with only one species known from subtropical habitats. Many specialise in living in cold, high-altitude upland rivers, streams, and lakes.
The yellowtail amberjack, yellowtail kingfish, hiramasa or great amberjack is a large fish found in the Southern Ocean. Although previously thought to be found in all oceans and seas, recent genetic analysis restricts S. lalandi proper to the Southern Hemisphere waters. However, they are found in Northern Hemisphere waters during certain times of the year. The fish was given its name by Monsieur de Lalande, a naturalist who first informed zoologist Achille Valenciennes of the existence of this species. His reason for the use of the word Seriola to name the fish is uncertain, but the second word lalandi was derived from his surname.
The New Zealand bigeye is a species of marine ray-finned fish, a sweeper from the family Pempheridae. It is endemic to the waters around New Zealand. It inhabitants rocky shores with plentiful overhangs and crevices at depths of from near the surface to 70 metres (230 ft).
The New Zealand smelt, also known as the New Zealand common smelt or New Zealand cucumber fish, is a smelt of the family Retropinnidae, found only in New Zealand at shallow depths in estuaries and rivers. Their length is between 8 and 13 cm.
The hāpuku, hapuka or whapuku, also known as groper, is a wreckfish of the family Polyprionidae, found around southern Australia, southern South America, South Africa, Tristan da Cunha and New Zealand at depths between 30 and 800 m. Its length is between 60 and 180 cm, and it can weigh up to 100 kg. It is sometimes described locally as cod, although that properly refers to other fish.
Blue moki is a species of marine ray finned fish belonging to the family Latridae, the trumpeters. It is native to the southwestern Pacific Ocean around New Zealand and occasionally off southeastern Australia at depths of 10 metres (33 ft) and greater. Juveniles inhabit inshore waters, preferring rocky reefs while adults mostly occur in offshore waters forming schools over open bottoms. Some solitary adults can be found on reefs. This species can reach a length of 80 centimetres (31 in) FL, though most do not exceed 63 centimetres (25 in) TL. This species is commercially important and is also popular as a game fish.
The New Zealand longfin eel is a species of freshwater eel that is endemic to New Zealand. It is the largest freshwater eel in New Zealand and the only endemic species – the other eels found in New Zealand are the native shortfin eel, also found in Australia, and the naturally introduced Australian longfin eel. Longfin eels are long-lived, migrating to the Pacific Ocean near Tonga to breed at the end of their lives. They are good climbers as juveniles and so are found in streams and lakes a long way inland. An important traditional food source for Māori, longfin eels numbers are declining and they are classified as endangered, but over one hundred tonnes are still commercially fished each year.
The Port Jackson shark is a nocturnal, oviparous type of bullhead shark of the family Heterodontidae, found in the coastal region of southern Australia, including the waters off Port Jackson. It has a large, blunt head with prominent forehead ridges and dark brown harness-like markings on a lighter grey-brown body, and can grow up to 1.65 metres (5.5 ft) long. They are the largest in the genus Heterodontus.
Arripis trutta, known as kahawai in New Zealand and as the Australian salmon in Australia, is a South Pacific marine fish and one of the four extant species within the genus Arripis, native to the cooler waters around the southeastern Australian coasts and the New Zealand coastline. Other common names for this species include Eastern Australian salmon, bay trout, blackback salmon, buck salmon, cocky salmon, colonial salmon, newfish and salmon trout.
The shore plover, also known as the shore dotterel or by its Māori name of tuturuatu, is a small plover endemic to New Zealand. Once found all around the New Zealand coast, it is now restricted to a few offshore islands. It is one of the world's rarest shorebirds: the population is roughly 200.
The pipipi, also known as brown creeper, New Zealand creeper, or New Zealand titmouse, is a small passerine bird endemic to the South Island of New Zealand. They are specialist insectivores, gleaning insects from branches and leaves. They have strong legs and toes for hanging upside down while feeding.
