Franz Steindachner
Franz Steindachner (11 November 1834 in Vienna – 10 December 1919 in Vienna) was an Austrian Zoology, zoologist, ichthyologist, and herpetologist. He published over 200 papers on fishes and over 50 papers on reptiles and amphibians. Steindachner described hundreds of new species of fish and dozens of new amphibians and reptiles. At least seven species of reptile have been named after him. Work and career Being interested in natural history, Steindachner took up the study of fossil fishes on the recommendation of his friend Eduard Suess (1831–1914). In 1860 he was appointed to the position of director of the fish collection at the Naturhistorisches Museum, a position which had remained vacant since the death of Johann Jakob Heckel (1790–1857). (in German). Steindachner's reputation as an Ichthyology, ichthyologist grew, and in 1868 he was invited by Louis Agassiz (1807–1873) to accept a position at the Museum of Comparative Zoology at Harvard University.

South Australia
South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories by area, and second smallest state by population. It has a total of 1.8 million people. Its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital Adelaide, or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 33,233. South Australia shares borders with all of the other mainland states, as well as the Northern Territory; it is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria, and to the south by the Great Australian Bight.M ...

Murray Hardyhead
The Murray hardyhead (''Craterocephalus fluviatilis'') is a species of fish in the family Atherinidae endemic to inland parts of southeastern Australia. The fish is an omnivore, feeding on small crustaceans, aquatic insects and algae Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular mic .... Conservation The fish was once widespread and abundant in the Murray and Murrumbidgee River systems in southern NSW and northern Victoria. However, they have suffered a serious population decline and now seem to be limited to a few sites, mainly in northern Victoria. There are very few recent records of Murray hardyheads from NSW. The main threat to remaining populations is increasing salinity and lack of water. Murray hardyheads are now listed as an endangered species in NSW and threatened in V ...

Finke River Hardyhead
The Finke River hardyhead (''Craterocephalus centralis'') is a species of fish in the family Atherinidae. It is endemic to the Finke River system in the Northern Territory, where it is widespread in open water or around aquatic vegetation. They occur in a wide range of salinity and pH and in Summer seek refuge in semi-permanent water holes. They are omnivores and feed on small crustaceans, insects, gastropods, polychaete worms, algae and fish eggs. This species shows a wide tolerance to temperature and salinity and is omnivore, probably spawning during warmer months. It was previously mis-identified as ''Craterocephalus eyresii ''Craterocephalus eyresii'', the Lake Eyre hardyhead, is a species of freshwater silverside from the family Atherinidae which is endemic to the Lake Eyre basin in Australia.

Darling River Hardyhead
The Darling River hardyhead (''Craterocephalus amniculus'') is a species of fish in the family Atherinidae endemic to Australia. The species name ''amniculus'' is from the Latin meaning a small creek or stream, in reference to the habitat where these fish are often found. ''Craterocephalus amniculus'' is recorded to be vulnerable to becoming an endangered species because of its restricted range, but the threats and information regarding this recording have not been verified or documented. Description The Darling River hardyhead is a small, laterally compressed fish that has a slender and elongated body. The large eyes are silvery in colour and it has narrow lips with few teeth in the mouth. The back is a dusky gold colour while it is silvery gold below. There is a dark, silvery stripe that runs the length of the flanks. They attain a maximum length of .

Sensu Lato
''Sensu'' is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law. Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage. Common qualifiers ''Sensu'' is the ablative case of the noun ''sensus'', here meaning "sense". It is often accompanied by an adjective (in the same case).

Lake Torrens
Lake Torrens (Kuyani: ''Ngarndamukia'') is a large ephemeral, normally endorheic salt lake in central South Australia. After sufficiently extreme rainfall events, the lake flows out through the Pirie-Torrens corridor to the Spencer Gulf. Islands on the lake include Andamooka Island and Murdie Island, both near the western shore; Trimmer Inlet runs between Andamooka Island and the shore, and Carrapateena Arm is an arm extending westwards south of Murdie Island. Description Lake Torrens lies between the Arcoona Plateau to the west and the Flinders Ranges to the east, about north of Port Augusta and about north of the Adelaide city centre. The lake is approximately above sea level,Barker, McCaskill & Ward, p.173, 1995 with a maximum depth of 1 m. It is located within the boundaries of Lake Torrens National Park.

Flinders Ranges
The Flinders Ranges are the largest mountain range in South Australia, which starts about north of Adelaide. The ranges stretch for over from Port Pirie to Lake Callabonna. The Adnyamathanha people are the Aboriginal group who have inhabited the range for tens of thousands of years. Its most well-known landmark is Wilpena Pound / Ikara, a formation that creates a natural amphitheatre covering and containing the range's highest peak, St Mary Peak (). The ranges include several national parks, the largest being the Ikara-Flinders Ranges National Park, as well as other protected areas. It is an area of great geological and palaeontological significance, and includes the oldest fossil evidence of animal life was discovered. The Ediacaran Period and Ediacaran biota take their name from the Ediacara Hills within the ranges. In August 2022, a nomination for the Flinders Ranges to be named a World Heritage Site was lodged.

Lake Frome / Munda is a large endorheic lake in the Australian state of South Australia to the east of the Northern Flinders Ranges. It is a large, shallow, unvegetated salt pan, long and wide, lying mostly below sea level and having a total surface area of . It only rarely fills with brackish water flowing down usually dry creeks in the Northern Flinders Ranges from the west, or exceptional flows down the Strzelecki Creek from the north. The Adnyamathanha name for the lake is ''Munda''. Europeans named the lake ''Frome'' after Edward Charles Frome, after he mapped the area in 1843.

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.
