John Gilchrist (zoologist)
John Dow Fisher Gilchrist (1866–1926) was a Scottish ichthyologist, who established ichthyology as a scientific discipline in South Africa. He was instrumental in the development of marine biology in South Africa and of a scientifically based local fishing industry. Education and career Gilchrist was born in Anstruther, Fife, Scotland in 1866. His early education was at Madras College, St Andrews, Scotland. He studied at the University of St Andrews and the University of Edinburgh, graduating with a Bachelor of Science (BSc) and a Master of Arts (MA). He was awarded an 1851 Exhibition scholarship for advanced studies and research, which enabled him to study feeding in marine fishes. After further studies at the University of Munich and the University of Zurich he obtained his PhD in geology at Jena University in 1894. He studied marine biology in Naples, Monaco and the Isle of Man before returning to teach zoology at the University of Edinburgh. During his three months at N ...

William Wardlaw Thompson
William Wardlaw Thompson (date of birth unknown - died 1917) was a South African ichthyologist and zoologist. It is known that he was educated at the South African College in Cape Town between 1858 and 1863 and that he obtained a post on the civil service of the Cape Colony in 1877 in the Railway Department as a temporary clerk. In January 1878 he secured a permanent post as a clerk in the Public Works Department, where he was promoted to First Clerk in 1882. In January 1885 he was transferred to the position of Chief records Clerk at the Crown Lands Office being promoted in July 1889 to first class clerk at the Department of Agriculture attaining the post of acting chief clerk there in November 1897. Prior to this he had taken and passed his Civil Service Law examinations and he also served with the Duke of Edinburgh's Own Volunteer Rifles in the Transkei during the 9th Frontier War in February to May 1879 and in Basutoland in September 1880 to March 1881 during the Basuto Gu ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Lethrinidae
Lethrinidae are a family of ray-finned fishes belonging to the order Spariformes commonly known as emperors, emperor breams, and pigface breams. These fish are found in tropical waters of the Pacific and Indian Oceans, and ''Lethrinus atlanticus'' is also found in the eastern Atlantic Ocean. They are benthic feeders, consuming invertebrates and small fishes. Some species have molariform teeth which they use to eat shelled invertebrates, such as molluscs and crabs. Taxonomy Lethrinidae was first proposed as a family name by the French zoologist Charles Lucien Bonaparte in 1831. Traditionally this family has been classified within the Perciformes, as part of the group of families some authorities called the "Sparoid lineage", this included the families Centrarchidae, Nemipteridae, Lethrinidae and Sparidae. Molecular phylogenetics as used in more modern classifications has meant that the Spariformes is recognised as a valid order within the Percomorpha containing six families, wi ...

Lethrinus Nebulosus
''Lethrinus nebulosus'', the spangled emperor, green snapper, morwong, north-west snapper, sand bream, sand snapper, sixteen-pounder, sharie, sheri and yellow sweetlip, is a species of marine ray-finned fish belonging to the family Lethrinidae, the emperors and emperor breams. This species is found the Indo-West Pacific region. Taxonomy ''Lethrinus nebulosus'' was first formally described as ''Sciaena nebulosa'' by the Swedish-speaking Finnish explorer, orientalist, naturalist Peter Forsskål and published in 1775 in ''Descriptiones animalium'' edited by Carsten Niebuhr with no Type locality being given but it is assumed to be the Red Sea. In 2022 the population of this species found off the coast of Southern Africa south of northern KwaZulu-Natal was recognised as a valid separate species from ''L. nebulosus'', ''Lethrinus scoparius''. Some authors place the genus ''Lethrinus'' in the monotypic subfamily Lethrininae, with all the other genera of Lethrinidae placed in the Mono ...

Lethrinus
''Lethrinus'' is a genus of marine ray-finned fishes belonging to the family Lethrinidae, the emperors and emperor breams. These fishes are mostly found in the Indian and western Pacific Oceans, with a single species in the eastern Atlantic Ocean. Taxonomy ''Lethrinus'' was first proposed as a genus in 1829 by the French zoologist Georges Cuvier. In 1912 David Starr Jordan and William Francis Thompson designated ''Sparus choerorynchus'' as the type species of the genus. ''Sparus choerorynchus'' had been described in 1801 by Marcus Elieser Bloch and Johann Gottlob Theaenus Schneider with its type locality given as Japan. ''Sparus choerorynchus'' is now considered to be a synonym of ''Lethrinus nebulosus'' (Forsskål 1775). Some authors place this genus in the monotypic subfamily Lethrininae, with all the other genera of Lethrinidae placed in the Monotaxinae, however, the 5th edition of ''Fishes of the World'' does not recognise the subfamilies traditionally accepted within the f ...

Fish Described In 1908
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...

Taxa Named By John Dow Fisher Gilchrist
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
