Barred Fingerfin
The barred fingerfin (''Cheilodactylus pixi'') is a species of marine ray-finned fish, belonging to the family Cheilodactylidae, commonly referred to as morwongs. It is found only in the southeastern Atlantic and southwestern Indian Oceans off the coasts of South Africa. Taxonomy The barred fingerfin was first formally described in 1980 by the South African ichthyologist Margaret Mary Smith with the type locality given as off the mouth of the Kowie River in the Eastern Cape in South Africa. Phylogenetic analyses and genetic studies of the morwongs have not supported the traditional arrangement of the families Cheilodactylidae and Latridae. This has led to some authorities suggesting that the majority of species in Cheilodactylidae should be placed in Latridae. A result of this rearrangement is that the only species which would remain in Cheilodactylidae are this species and '' C. fasciatus'', both from southern Africa. This is because these analyses resolved the genus ''Cheiloda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Margaret Mary Smith
Margaret Mary Smith (née MacDonald) was born on 26 September 1916 in Indwe, Eastern Cape, a small village on the border of the Transkei. She was an ichthyologist, accomplished fish illustrator, and an academic. Early life Margaret Mary Smith was the daughter of Chisholm MacDonald and Helen Evelyn Zondagh. Her father was a medical doctor and her mother a descendant of the Voortrekker leader Jacobus Johannes Uys. She was the youngest of three children. Margaret attended Indwe High School. She was head girl and head scholar as well as chairperson of the debating society, captain of the netball and tennis teams. From 1934 to 1936 she attended Rhodes University, where she achieved a Bachelor of Science degree majoring in physics and chemistry. She also attended the Grahamstown Training College School of Music and obtained her University Teachers' Licentiate in Music for singing in 1936. Career In 1937, after she obtained her degree, she was hired as a senior demonstrator in chemi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goniistius
''Goniistius'' is a subgenus of marine ray-finned fishes, traditionally classified as being within the genus ''Cheilodactylus'' and belonging to the family Cheilodactylidae, known as morwongs, although this name is not unique to this family and the true taxonomic placement of this taxon requires clarification. They are found in the Pacific Ocean and southeastern Indian Ocean. Taxonomy ''Goniistius'' was created as a subgenus of ''Cheilodactylus'' in 1862 by the American ichthyologist Theodore Nicholas Gill with ''Cheilodactylus zonatus'' designated as its type species. The name of the subgenus is a compound of ''gonio'' meaning “angle” and ''istios'' which means “sail”, Gill did not explain what his name alluded to but he may have been referring to the deep incision between spiny and soft-rayed parts of the dorsal fin of the type species. Genetic and morphological analyses of the family Cheolodactylidae have found that the family as traditionally arranged is polyphylet ...

Copper Shark
The copper shark (''Carcharhinus brachyurus''), bronze whaler, or narrowtooth shark, is a species of requiem shark, family Carcharhinidae, and the only member of its genus found mostly at temperate latitudes. It is distributed in a number of separate populations in the northeastern and southwestern Atlantic, off southern Africa, in the northwestern and eastern Pacific, and around Australia and New Zealand, with scattered reports from equatorial regions. This species can be found from brackish rivers and estuaries, to shallow bays and harbors, to offshore waters deep or more. Females are found apart from males for most of the year, and conduct seasonal migrations. A large species reaching long, the copper shark is difficult to distinguish from other large requiem sharks. It is characterized by its narrow, hook-shaped upper teeth, lack of a prominent ridge between the dorsal fins, and plain bronze coloration. Feeding mainly on cephalopods, bony fishes, and other cartilaginous fis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KwaZulu Natal
KwaZulu-Natal (, also referred to as KZN and known as "the garden province") is a province of South Africa that was created in 1994 when the Zulu bantustan of KwaZulu ("Place of the Zulu" in Zulu) and Natal Province were merged. It is located in the southeast of the country, with a long shoreline on the Indian Ocean and sharing borders with three other provinces and the countries of Mozambique, Eswatini and Lesotho. Its capital is Pietermaritzburg, and its largest city is Durban. It is the second-most populous province in South Africa, with slightly fewer residents than Gauteng. Two areas in KwaZulu-Natal have been declared UNESCO World Heritage Sites: the iSimangaliso Wetland Park and the uKhahlamba Drakensberg Park. These areas are extremely scenic as well as important to the surrounding ecosystems. During the 1830s and early 1840s, the northern part of what is now KwaZulu-Natal was established as the Zulu Kingdom while the southern part was, briefly, the Boer Natalia ...

Coffee Bay
Coffee Bay ( af, Koffiebaai) is a town on the Wild Coast Region, Eastern Cape, Wild Coast of the Eastern Cape Province of South Africa. It is located about 250 kilometres south of the city of Durban and has a population of 258 people. The town is named after the hundreds of coffee trees which grew from beans either scattered by a shipwreck or by plunderers. A holiday resort in Tembuland is located 80 km south-east of Viedgesville. It can be reached via a turn-off from the N2 highway. The Mthatha River has its mouth near Coffee Bay. History One of the arguments is that the town was named Coffee Bay in 1893 after a shipwreck lost its cargo of coffee beans near the coast of Coffee Bay, although there may no longer be any coffee trees or beans in the Coffee Bay area. The municipality is located in an area that was previously part of the Xhosa people, Xhosa bantustan, Transkei, and the population is still predominantly Xhosa.

False Bay
False Bay (Afrikaans ''Valsbaai'') is a body of water in the Atlantic Ocean between the mountainous Cape Peninsula and the Hottentots Holland Mountains in the extreme south-west of South Africa. The mouth of the bay faces south and is demarcated by Cape Point to the west and Cape Hangklip to the east. The north side of the bay is the low-lying Cape Flats, and the east side is the foot of the Hottentots Holland Mountains to Cape Hangklip which is at nearly the same latitude as Cape Point. In plan the bay is approximately square, being roughly the same extent from north to south as east to west, with the southern side open to the ocean. The seabed slopes gradually down from north to south, and is mostly fairly flat unconsolidated sediments. Much of the bay is off the coast of the City of Cape Town, and it includes part of the Table Mountain National Park Marine Protected Area and the whole of the Helderberg Marine Protected Area. The name "False Bay" was applied at least three hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans (whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against rollin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Specimen
In biology, a type is a particular wiktionary:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the ...

Port Alfred
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zh ...

Aplodactylus
''Aplodactylus'' is a genus of marine ray-finned fishes, commonly known as marblefishes or sea carps. It is the only genus in the monogeneric family, Aplodactylidae. The fishes in this genus are found in the south eastern Indian Ocean and the southern Pacific Ocean. Taxonomy Aplodactylus was described in 1832 by the French zoologist Achille Valenciennes with ''Aplodactylus punctatus'', which Valenciennes described from the type specimen collected from Valparaiso in Chile, as its only species, being the type species by monotypy. The family had previously contained two genera with the monospecific ''Crinodon'' being recognised as a synonym of ''Aplodactylus'' by Barry C. Russell in 2000. The family, Aplodactylidae was created as Haplodactylidae by the German born British ichthyologist Albert Günther in 1859, the Dutch ichthyologist Pieter Bleeker corrected that to its current name later the same year. The family is regarded as part of the superfamily Cirrhitoidea, which is place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chironemus
''Chironemus'' is a genus of marine ray finned fish, commonly known as kelpfishes, belonging to the family Chironemidae. They are found in the temperate waters of the Southern Pacific Ocean. Taxonomy The Kelpfishes were placed in the monogeneric family Chironemidae in 1862 by the American ichthyologist Theodore Nicholas Gill. The genus had been described in 1829 by the French zoologist Georges Cuvier when he had described the type species ''Chironemus georgianus''. The family is regarded as part of the superfamily Cirrhitoidea, which is placed within the order Perciformes in the 5th Edition of ''Fishes of the World'', however other authorities place this clade within a new order within the wider Percomorpha, Centrarchiformes. The name of the genus is from Greek ''cheir'' meaning "hands" and ''nema'' meaning "thread". Species The currently recognized species in this genus are: * ''Chironemus bicornis'' (Steindachner, 1898) * ''Chironemus delfini'' (Porter, 1914) * ''Chironemu ...
