Zanclorhynchus
''Zanclorhynchus'' is a genus of marine ray-finned fishes belonging to the family Congiopodidae, the pigfishes or horsefishes. These fishes are found in the Southern Ocean. Taxonomy ''Zanclorhynchus'' was first described as a genus in 1880 by the German-born British ichthyologist Albert Günther as a monotypic genus, its only member being the new species Günther described in the same paper, ''Zanclorhynchus spinifer'', with its type locality given as Kerguelen Island. The 5th edition of ''Fishes of the World'' classifies this genus in the family Congiopodidae but other authorities classify it within the family Zanclorhynchidae, alongside the genus '' Alertichthys''. The genus name is a compound of ''zanklon'', which means "sickle", and ''rhynchus'', meaning "snout", assumed to be an allusion to the pointed snout of adult ''Z. spinifer''. Species ''Zanclorhynchus'' contains 2 recognised species: * '' Zanclorhynchus chereshnevi'' Balushkin & Zhukov, 2016 (Chereshnev's horsefis ...

Zanclorhynchus Spinifer
''Zanclorhynchus spinifer'', also known as the Antarctic horsefish or spiny horsefish, is a species of marine ray-finned fish belonging to the family Congiopodidae, the horsefishes or pigfishes. This fish is found in the Southern Ocean where it occurs at depths of from . This species grows to a length of TL and is of minor importance to the commercial fishery industry. Taxonomy ''Zanclorhynchus spinifer'' was first formally described in 1880 by the German-born British ichthyologist Albert Günther With the type locality given as Kerguelen Island. Günther classified the newly described species in a new monotypic genus, ''Zanclorhynchus'', which remained monotypic until Chereshnev's horsefish (''Z. chereshnevi'') was described in 2016. Subspecies ''Zanclorhynchus spinifer'' has a number of subspecies proposed, these are: * ''Zanclorhynchus spinifer armatus'' Zhukov, 2019 Prince Edward Islands, Crozet Islands * ''Zanclorhynchus spinifer heracleus'' Zhukov & Balushkin, 2018 ...

Congiopodidae
Congiopodidae, commonly known as pigfishes, horsefishes and racehorses, is a family of ray-finned fish classified with in the order Scorpaeniformes. These fishes are native to the Southern Hemisphere. Taxonomy Congiopodidae was first formally recognised as a family by the American biologist Theodore Gill in 1889. The 5th edition of ''Fishes of the World'' classifies the family within the suborder Scorpaenoidei which in turn is classified within the order Scorpaeniformes. Other authorities place the Scorpaenoidei within the Perciformes. The monophyly of the Congiopodidae as set out in ''Fishes of the World'' is not universally agreed upon. Some authorities classify the genus ''Perryena'' in its own subfamily, Perryeninae, in the stonefish family Synanceiidae. The genera ''Alertichthys'' and ''Zanclorhynchus'' are classified within the family Zanclorhynchidae leaving ''Congiopodus'' as the only genus in the monotypic Congiopodidae.

Macquarie Island
Macquarie Island is an island in the southwestern Pacific Ocean, about halfway between New Zealand and Antarctica. Regionally part of Oceania and politically a part of Tasmania, Australia, since 1900, it became a Tasmanian State Reserve in 1978 and was inscribed as a UNESCO World Heritage Site in 1997. It was a part of Esperance Municipality until 1993, when the municipality was merged with other municipalities to form Huon Valley Council. The island is home to the entire royal penguin population during their annual nesting season. Ecologically, the island is part of the Antipodes Subantarctic Islands tundra ecoregion. Since 1948, the Australian Antarctic Division (AAD) has maintained a permanent base, the Macquarie Island Station, on the isthmus at the northern end of the island at the foot of Wireless Hill. The population of the base, constituting the island's only human inhabitants, usually varies from 20 to 40 people over the year. A heliport is located nearby. In Septemb ...

Heard Island And McDonald Islands
The Territory of Heard Island and McDonald Islands (HIMI) is an Australian external territory comprising a volcanic group of mostly barren Antarctic islands, about two-thirds of the way from Madagascar to Antarctica. The group's overall size is in area and it has of coastline. Discovered in the mid-19th century, the islands lie on the Kerguelen Plateau in the Indian Ocean and have been an Australian territory since 1947. They contain Australia's only two active volcanoes. The summit of one, Mawson Peak, is higher than any mountain in all other Australian states or territories, except Dome Argus, Mount McClintock and Mount Menzies in the Australian Antarctic Territory. The islands are among the most remote places on Earth: They are located about southwest of Perth, southwest of Cape Leeuwin, Australia, southeast of South Africa, southeast of Madagascar, north of Antarctica, and southeast of the Kerguelen Islands (part of French Southern and Antarctic Lands).

Crozet Islands
The Crozet Islands (french: Îles Crozet; or, officially, ''Archipel Crozet'') are a sub-Antarctic archipelago of small islands in the southern Indian Ocean. They form one of the five administrative districts of the French Southern and Antarctic Lands. History Discovery and early history The Crozet Islands were discovered on 24 January 1772, by the expedition of French explorer Marc-Joseph Marion du Fresne, aboard ''Le Mascarin''. His second-in-command Jules (Julien-Marie) Crozet landed on Île de la Possession, claiming the archipelago for France. The expedition continued east and landed in New Zealand, where Captain Marion and much of his crew were killed and cannibalized by Maori. Crozet survived the disaster, and successfully led the survivors back to their base in Mauritius. In 1776, Crozet met James Cook at Cape Town, at the start of Cook's third voyage. Crozet shared the charts of his ill-fated expedition, and as Cook sailed eastward, he stopped at the islands, naming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prince Edward Islands
The Prince Edward Islands are two small uninhabited islands in the sub-Antarctic Indian Ocean that are part of South Africa. The islands are named Marion Island (named after Marc-Joseph Marion du Fresne, 1724–1772) and Prince Edward Island (named after Prince Edward, Duke of Kent and Strathearn, 1767–1820). The islands in the group have been declared Special Nature Reserves under the South African Environmental Management: Protected Areas Act, No. 57 of 2003, and activities on the islands are therefore restricted to research and conservation management. Further protection was granted when the area was declared a marine protected area in 2013. The only human inhabitants of the islands are the staff of a meteorological and biological research station run by the South African National Antarctic Programme on Marion Island. History The islands were discovered on 4 March 1663 by Barent Barentszoon Lam of the Dutch East India Company ship ''Maerseveen'' and were named ''Dina' ...

Total Length
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.

Anus
The anus (Latin, 'ring' or 'circle') is an opening at the opposite end of an animal's digestive tract from the mouth. Its function is to control the expulsion of feces, the residual semi-solid waste that remains after food digestion, which, depending on the type of animal, includes: matter which the animal cannot digest, such as bones; Summary at food material after the nutrients have been extracted, for example cellulose or lignin; ingested matter which would be toxic if it remained in the digestive tract; and dead or excess gut bacteria and other endosymbionts. Amphibians, reptiles, and birds use the same orifice (known as the cloaca) for excreting liquid and solid wastes, for copulation and egg-laying. Monotreme mammals also have a cloaca, which is thought to be a feature inherited from the earliest amniotes via the therapsids. Marsupials have a single orifice for excreting both solids and liquids and, in females, a separate vagina for reproduction. Female placental mamm ...
