John Dow Fisher Gilchrist
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 Nap ...

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 ...

Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from '' Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Act ...

Engraulidae
An anchovy is a small, common forage fish of the family Engraulidae. Most species are found in marine waters, but several will enter brackish water, and some in South America are restricted to fresh water. More than 140 species are placed in 17 genera; they are found in the Atlantic, Indian and Pacific Oceans, and in the Black Sea and the Mediterranean Sea. Anchovies are usually classified as oily fish. Genera Characteristics Anchovies are small, green fish with blue reflections due to a silver-colored longitudinal stripe that runs from the base of the caudal (tail) fin. They range from in adult length, and their body shapes are variable with more slender fish in northern populations. The snout is blunt with tiny, sharp teeth in both jaws. The snout contains a unique rostral organ, believed to be electro-sensory in nature, although its exact function is unknown. The mouth is larger than that of herrings and silversides, two fish which anchovies closely resemble in ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' ( Atlantic) before the Pacific was surmised. Conversely, Chinese explorers in the Indian Ocean during the 15th century called it the Western Oceans. In Anci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxa Named By John Dow Fisher Gilchrist
In biology, a taxon (back-formation from ''taxonomy''; plural 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. 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 set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
