Thymichthys Politus
The red handfish (''Thymichthys politus'', formerly ''Brachionichthys politus'') is a species of handfish in the genus ''Thymichthys,'' found in Frederick Henry Bay, Tasmania. Description The red handfish is distinguished by its small, flattened wart-like protuberances that cover its body and red colouration. Two colour morphs exist, a bright red morph with red colour on both body and fins, with a black line separating the white fin edges and a mottled morph with pink body covered in many red patches, with translucent pink fins expressing some bright red patches. They measure an average standard length of 61.4 mm (2.4 in) and an average total length of 80.1 mm (3.2 in). Like other handfishes, they have large developed pectoral fins, which they use to walk along the sea floor. Distribution Historically, the species was found in multiple subpopulations in Tasmania, including Port Arthur, Fortescue Bay, the Actaeon Islands, D'Entrecasteaux Channel, and the Fo ...

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Tasmania
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Threatened Species Protection Act 1995
The ''Threatened Species Protection Act 1995'' (TSP Act), is an act of the Parliament of Tasmania that provides the statute relating to conservation of flora and fauna. Its long title is An Act to provide for the protection and management of threatened native flora and fauna and to enable and promote the conservation of native flora and fauna. It received the royal assent on 14 November 1995. As of 25 November 2020, the TSP Act is administered by the Department of Primary Industries, Parks, Water and Environment (Tasmania) and is the primary legislation for the listing, protection and conservation of threatened native flora and fauna in Tasmania. Threatened species in Tasmania can also be listed on the Environment Protection and Biodiversity Conservation Act 1999, which is the primary national legislation for the protection of threatened species in Australia. The objectives of the TSP Act are to ensure the survival of native flora and fauna as well to encourage, educate and as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environment Protection And Biodiversity Conservation Act 1999
The ''Environment Protection and Biodiversity Conservation Act 1999'' (Cth) is an Act of the Parliament of Australia that provides a framework for protection of the Australian environment, including its biodiversity and its natural and culturally significant places. Enacted on 17 July 2000, it established a range of processes to help protect and promote the recovery of threatened species and ecological communities, and preserve significant places from decline. The Act is administered by the Department of Agriculture, Water and the Environment. Lists of threatened species are drawn up under the Act, and these lists, the primary reference to threatened species in Australia, are available online through the Species Profile and Threats Database (SPRAT). As an Act of the Australian Parliament, it relies for its constitutional validity upon the legislative powers of the Parliament granted by the Australian Constitution, and key provisions of the Act are largely based on a number ...

Fortescue Bay
Fortescue Bay or Baje Dolomien is a bay in southeast Tasmania, Australia. It is located east of Port Arthur, Tasmania, and makes up part of Tasman National Park. Within the bay are two smaller nested bays, Canoe Bay and Bivouac Bay. History Timber mill During the early 1900s, a timber mill was started at Fortescue Bay by G. Albury and Turner Brothers. At the beginning of the 1920s, the Gathercole Brothers company began advertising for men to work at their mill. It is possible that the Gathercole Brothers carried on operation of the mill owned by G. Albury and Turner Brothers, as they owned several mills around Port Arthur.

Port Arthur, Tasmania
Port Arthur is a town and former convict settlement on the Tasman Peninsula, in Tasmania, Australia. It is located approximately southeast of the state capital, Hobart. The site forms part of the Australian Convict Sites, a World Heritage property consisting of 11 remnant penal sites originally built within the British Empire during the 18th and 19th centuries on fertile Australian coastal strips. Collectively, these sites, including Port Arthur, are described by UNESCO as "... the best surviving examples of large-scale convict transportation and the colonial expansion of European powers through the presence and labour of convicts."
