Chrysoblephus Gibbiceps
''Chrysoblephus gibbiceps'', the red stumpnose, red stumpnose seabream or Miss Lucy, is a species of marine ray-finned fish belonging to the family Sparidae, the seabreams and porgies. This fish is endemic to the southwestern Indian Ocean off the coast of South Africa. The International Union for Conservation of Nature classifies this species as Endangered. Taxonomy ''Chrysoblephus gibbiceps'' was first formally described in 1830 as ''Chrysophrys gibbiceps'' by the French zoologist Achille Valenciennes with its type localitygiven as the Cape of Good Hope in South Africa. In 1839 William John Swainson classified Valenciennes' ''C. gibbericeps'' in a new subgenus of ''Chrysophrys'' he called '' Chrysoblephus'' and named it as its only species, making this species the type species of ''Chrysoblephus'' by monotypy. The genus ''Chrysoblephus'' is placed in the family Sparidae within the order Spariformes by the 5th edition of ''Fishes of the World''. Some authorities classify this g ...

Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "'' Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gonochoristic
In biology, gonochorism is a sexual system where there are only two sexes and each individual organism is either male or female. The term gonochorism is usually applied in animal species, the vast majority of which are gonochoric. Gonochorism contrasts with simultaneous hermaphroditism but it may be hard to tell if a species is gonochoric or sequentially hermaphroditic. (e.g. Parrotfish, ''Patella ferruginea''). However, in gonochoric species individuals remain either male or female throughout their lives. Species that reproduce by thelytokous parthenogenesis and do not have males can still be classified as gonochoric. Terminology The term is derived from Greek (''gone'', generation) + (''chorizein,'' to separate). The term gonochorism originally came from German gonochorismus. Gonochorism is also referred to as unisexualism or gonochory. Evolution Gonochorism has evolved independently multiple times and is very evolutionary stable in animals. Its stability and advanta ...

Congener (biology)
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysoblephus Anglicus
''Chrysoblephus anglicus'', the Englishman seabream, is a species of marine ray-finned fish belonging to the family Sparidae, the seabreams and porgies. This fish is endemic to Southern Africa. Taxonomy ''Chrysoblephus anglicus'' was first formally described as ''Chrysophrys anglicus'' in 1908 by the ichthyologists John Dow Fisher Gilchrist, a Scot, and William Wardlaw Thompson, a South African, with its type locality given as Durban in KwaZulu-Natal, South Africa. The genus '' Chrysoblephus'' is placed in the family Sparidae within the order Spariformes by the 5th edition of ''Fishes of the World''. Some authorities classify this genus in the subfamily Sparinae, but the 5th edition of Fishes of the World does not recognise subfamilies within the Sparidae. Etymology ''Chrysoblephus anglicus'' has the specific name ''anglicus'', which means "English". This presumably follows its common name in South Africa, Englishman seabream. Description ''Chrysoblephus anglicus'' has a dorsa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Margate, South Africa
Margate is a coastal resort town in the Kwa-Zulu Natal province, about 20 kilometres southwest of Port Shepstone. The river which flows into the sea at Margate is called "Nkhongweni" ''(place of entreaty)'' as the original inhabitants of the area were reputed to be so mean resulting in travellers begging for hospitality. It is one of the major hubs for tourists who are looking to visit the eastern coastline of South Africa. History In 1908, Henry Richardson, an English surveyor laid out the town and named it Margate after another seaside resort on the northern coast of the county of Kent, in the United Kingdom. Margate hit the world headlines in 1922 (although this date is often disputed and stated as 1924) when an enormous, white, furry creature (dubbed "Trunko" due to it having an elephantine trunk) was washed up on the beach. The "Margate monster" was too decomposed to be identified. Geography Margate is located on a series of hills overlooking the Indian Ocean with the alti ...

East London, South Africa
East London ( xh, eMonti; af, Oos-Londen) is a city on the southeast coast of South Africa in the Buffalo City Metropolitan Municipality of the Eastern Cape province. The city lies on the Indian Ocean coast, largely between the Buffalo River and the Nahoon River, and hosts the country's only river port. , East London had a population of over 267,000 with over 755,000 in the metropolitan area. History Early history John Bailie, one of the 1820 Settlers, surveyed the Buffalo River mouth and founded the town in 1836. There is a memorial on Signal Hill commemorating the event. The city formed around the only river port in South Africa and was originally known as Port Rex. Later it was renamed London in honour of the capital city of the United Kingdom, hence the name East London. This settlement on the West Bank was the nucleus of the town of East London, which was elevated to city status in 1914. During the early to mid-19th century frontier wars between the British settler ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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.

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 ...
