Family (biology)
Family ( la, familia, plural ') 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". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Etmopteridae
The Etmopteridae are a family of sharks in the order Squaliformes, commonly known as lantern sharks. Their name comes from the presence of light-producing photophore A photophore is a glandular organ that appears as luminous spots on various marine animals, including fish and cephalopods. The organ can be simple, or as complex as the human eye; equipped with lenses, shutters, color filters and reflectors, ...s on their bodies. The members of this family are small, under long, and are found in deep waters worldwide. The 45 species are placed in five genera. Three-quarters of the species are in the genus ''Etmopterus''.

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Cape Province
The Province of the Cape of Good Hope ( af, Provinsie Kaap die Goeie Hoop), commonly referred to as the Cape Province ( af, Kaapprovinsie) and colloquially as The Cape ( af, Die Kaap), was a province in the Union of South Africa and subsequently the Republic of South Africa. It encompassed the old Cape Colony, as well as Walvis Bay, and had Cape Town as its capital. In 1994, the Cape Province was divided into the new Eastern Cape, Northern Cape and Western Cape provinces, along with part of the North West. History When the Union of South Africa was formed in 1910, the original Cape Colony was renamed the Cape Province. It was by far the largest of South Africa's four provinces, as it contained regions it had previously annexed, such as British Bechuanaland (not to be confused with the Bechuanaland Protectorate, now Botswana), Griqualand East (the area around Kokstad) and Griqualand West (area around Kimberley). As a result, it encompassed two-thirds of South Africa's terr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natal Province
The Province of Natal (), commonly called Natal, was a province of South Africa from May 1910 until May 1994. Its capital was Pietermaritzburg. During this period rural areas inhabited by the black African population of Natal were organized into the bantustan of KwaZulu, which was progressively separated from the province, becoming partially autonomous in 1981. Of the white population, the majority were English-speaking people of British descent, causing Natal to become the only province to vote "No" to the creation of a republic in the referendum of 1960, due to very strong monarchist, pro-British Commonwealth, and anti-secessionist sentiment. In the latter part of the 1980s, Natal was in a state of violence between the Inkatha Freedom Party and the African National Congress, with violence subsidising soon after the first non-racial election in 1994.Taylor, Rupert.

South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively.

Brown Lanternshark
The brown lanternshark or bristled lanternshark (''Etmopterus unicolor'') is a little-known species of deep-sea dogfish shark in the family Etmopteridae. It is found off Japan and New Zealand, and possibly also South Africa and Australia, typically deeper than . This species can be distinguished from other lanternsharks by its coloration, which is a uniform dark gray or brown without the ventral surface being much darker and clearly delineated from the rest of the body. The brown lanternshark feeds on small bony fishes, cephalopods, and crustaceans. Reproduction is ovoviviparous, with females giving birth to 9–18 young. An unusually high proportion of individuals in Suruga Bay are hermaphrodites, with both male and female characteristics. Taxonomy The brown lanternshark was first described by Robert Engelhardt as ''Spinax unicolor'' in 1912, in the scientific journal ''Zoologischer Anzeiger''. The type specimen was a 55-cm-long female from Sagami Bay, Japan. In 1965, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etmopterus
''Etmopterus'' is a genus of lantern sharks in the squaliform family Etmopteridae. They are found in deep sea ecosystems of the Atlantic, Indian and Pacific Oceans. Ecology A number of species in this genus function as host to the specialized parasitic barnacle '' Anelasma squalicola'', which embeds itself into the skin of the shark and extracts nutrients from its bloodstream. Species There are currently 45 recognized species in this genus: * '' Etmopterus alphus'' Ebert, Straube, Leslie & Weigmann, 2016 (whitecheek lanternshark) * ''Etmopterus baxteri'' Garrick, 1957 (New Zealand lanternshark) * ''Etmopterus benchleyi'' Vásquez, Ebert & D. J. Long, 2015 (ninja lanternshark) * ''Etmopterus bigelowi'' Shirai & Tachikawa, 1993 (blurred lanternshark) * ''Etmopterus brachyurus'' H. M. Smith & Radcliffe, 1912 (short-tail lanternshark) * '' Etmopterus brosei'' Ebert, Leslie & Weigmann, 2021 * '' Etmopterus bullisi'' Bigelow & Schroeder, 1957 * '' Etmopterus burgessi'' ...
