Jaydia Queketti
''Jaydia queketti'', the spotfin cardinal or signal cardinalfish, is a species of ray-finned fish from the Indian Ocean, it is a member of the family Apogonidae. It has colonised the eastern Mediterranean Sea by way of the Suez Canal since 2004. Description ''Jaydia queketti'' has a compressed, oblong body which is covered in large scales. It has two dorsal fins, the first one has 7 spines, with the 3rd and 4th being the largest. The soft rays in the dorsal fin are longer than the spines. The anal fin lines up with the 2nd dorsal fin origin. The caudal fin is round. The pelvic fin lies directly underneath and in line with the pectoral fin. The mouth is slightly oblique and reaches back beyond the large eye, which in turn has a diemeter of nearly four times the length of the head. The preopercular edge is smooth. The body colour is grey to off-white, darkening on the back. Dark grey to brown spots on the body form irregular, longitudinal lines. There is a large dark ocellus on ...

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 ...

Suez Canal
The Suez Canal ( arz, قَنَاةُ ٱلسُّوَيْسِ, ') is an artificial sea-level waterway in Egypt, connecting the Mediterranean Sea to the Red Sea through the Isthmus of Suez and dividing Africa and Asia. The long canal is a popular trade route between Europe and Asia. In 1858, Ferdinand de Lesseps formed the Suez Canal Company for the express purpose of building the canal. Construction of the canal lasted from 1859 to 1869. The canal officially opened on 17 November 1869. It offers vessels a direct route between the North Atlantic and northern Indian oceans via the Mediterranean Sea and the Red Sea, avoiding the South Atlantic and southern Indian oceans and reducing the journey distance from the Arabian Sea to London by approximately , or 10 days at to 8 days at . The canal extends from the northern terminus of Port Said to the southern terminus of Port Tewfik at the city of Suez. In 2021, more than 20,600 vessels traversed the canal (an average of 56 per day). T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Frederick Whitlie Quekett
John Frederick Whitlie Quekett (b. London, 1849, d. Durban 5 July 1913) was a conchologist and museum curator who worked in South Africa, having emigrated there in 1871. He was the curator of the Durban Natural History Museum in June 1895. He retired in 1909 and died in Durban in 1913. Early life Quekket was born in London in 1849, his father was Professor John Thomas Quekett, after whom the Microscopy Club, is named, and his mother was Isabella Mary Anne Scott. He was educated in London. South Africa Quekket emigrated to South Africa in 1871. At some time in the early 1880s he was elected a Fellow of the Zoological Society of London. In 1886 he was tasked by the Natal Society in Pietermaritzburg to organise their collections and in 1888 was recorded as the honorary secretary of the Society’s Museum and Science Department. By 1891 he was the secretary and the first curator of the society’s museum, an institution which eventually became part of the Natal Museum. at this ti ...

Conchology
Conchology () is the study of mollusc shells. Conchology is one aspect of malacology, the study of molluscs; however, malacology is the study of molluscs as whole organisms, whereas conchology is confined to the study of their shells. It includes the study of land and freshwater mollusc shells as well as seashells and extends to the study of a gastropod's operculum. Conchology is now sometimes seen as an archaic study, because relying on only one aspect of an organism's morphology can be misleading. However, a shell often gives at least some insight into molluscan taxonomy, and historically the shell was often the only part of exotic species that was available for study. Even in current museum collections it is common for the dry material (shells) to greatly exceed the amount of material that is preserved whole in alcohol. Conchologists mainly deal with four molluscan orders: the gastropods (snails), bivalves (clams), Polyplacophora (chitons) and Scaphopoda (tusk shells). Ce ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Ichthyology
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish ( Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). According to FishBase, 33,400 species of fish had been described as of October 2016, with approximately 250 new species described each year. Etymology The word is derived from the Greek words ἰχθύς, ''ikhthus'', meaning "fish"; and λογία, ''logia'', meaning "to study". History The study of fish dates from the Upper Paleolithic Revolution (with the advent of "high culture"). The science of ichthyology was developed in several interconnecting epochs, each with various significant advancements. The study of fish receives its origins from humans' desire to feed, clothe, and equip themselves with useful implements. According to Michael Barton, a prominent ichthyologist and professor at Centre College, "the earliest ichthyologists were ''hunters and gatherers'' who had learned how to obtain the most use ...

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...
