Neochanna is a genus of six mudfish species, five restricted to New Zealand, and one to Tasmania with a small enclave on Wilson's Promontory, Victoria, Australia. New Zealand is an Island country in the south-western Pacific Ocean comprising two main landmasses (the North Island and the South Island Tasmania is an Australian island and state of the same name It is located south of the eastern side of the Continent, being separated from it by Bass Wilsons Promontory is a Peninsula that forms the southernmost part of the Australian mainland and is located at. For a topic outline on this subject see List of basic Australia topics. They are small (up to about 15 cm) freshwater fish that have become specialised for life in a distinctive type of habitat – swamps, drains, and forest pools that tend to dry up in summer. A centimetre ( American spelling: centimeter, symbol cm) is a unit of Length in the Metric system, equal to one hundredth They can exist in these habitats because they have the ability to aestivate during dry summers. Estivation or aestivation (from Latin aestas, summer also known as "summer sleep" is a state of Dormancy somewhat similar
Mudfish are an elongate, slender-bodied group of fish with blunt heads and small eyes. Many species lack pelvic fins, and this is one way to distinguish them from other members of the Galaxiidae family. The Anatomy of Fish is primarily governed by the physical characteristics of Water, which is much denser than air holds a relatively small amount of dissolved The Galaxiids are a family of mostly small freshwater Fish. Representatives occur throughout the southern hemisphere including South Africa, South America They also do not have barbels or scales. A barbel on a Fish is a slender whiskerlike tactile organ near the Mouth. In most biological nomenclature a scale ( Greek lepid, Latin squama) is a small rigid plate that grows out of an Animal
Spawning takes place at the beginning of the wet season and probably continues through to early spring. They are non-diadromous so do not have a saltwater phase as many other members of the Galaxiidae family do. Many types of fish undertake migrations on a regular basis on time scales ranging from daily to annual and with distances ranging from a few meters to thousands of kilometers
Mudfish, also called kowaro, are regarded as a taonga (treasured) species to Māori iwi in New Zealand, and all six species are threatened. A taonga in Māori culture is a treasured thing whether tangible or intangible This article discusses the Māori people of New Zealand For their language see Māori language, and for other meanings see Māori (disambiguation. In New Zealand society iwi (iwi form the largest everyday Social units in Māori populations. Once widespread in swamps and wetlands, mudfish are now found in only a few sites – mostly on private land. In New Zealand the Department of Conservation is working with landowners to protect these key remaining habitats. The Department of Conservation (In Māori, Te Papa Atawhai) commonly known by its acronym " DOC " is the state sector organisation
