Evynnis
''Evynnis'' is a genus of marine ray-finned fishes belonging to the Family (biology), family Sparidae, which includes the seabreams and porgies. The genus comprises 4 species, 3 in the Western Pacific Ocean and 1 in the Eastern Atlantic Ocean. Taxonomy ''Evynnis'' was first proposed as a monospecific genus, genus in 1912 by the American ichthyologists David Starr Jordan and William Francis Thompson (biologist), William Francis Thompson with ''Sparus cardinalis'', its only species, designated as its type species. ''Sparus cardinalis'' was first formally described in 1802 by Bernard Germain de Lacépède from China and Japan. This genus is placed in the family Sparidae within the Order (biology), 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. Taxonomy ''Evynnis'' combines ''eu'', meaning “well”, and ''hy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evynnis Tumifrons
''Evynnis tumifrons'', the yellowback seabream, crimson seabream, goldentail or red seabream, is a species of marine ray-finned fish belonging to the family Sparidae, which includes the seabreams and porgies. This fish is found in the Western Pacific Ocean off the coasts of East Asia. This species is an important food fish in the East China Sea and Japan. Taxonomy ''Evynnis tumifrons'' was first formally described as ''Chrysophrys tumifrons'' in 1843 by the Dutch zoologist Coenraad Jacob Temminck and the German zoologist Hermann Schlegel with its type locality given as Japan. In 1931 the Japanese ichthyologist Shigeho Tanaka renamed ''Chrysophrys cardinalis'', also described by Temminck and Schegel, as ''Evyniis japonica'' because '' Sparus cardinalis'' had been named by Bernard Germain de Lacépède in 1802. Temminck and Schlegel had used two types in their description of ''C. tumifrons'' and the larger of the two was shown to be an example of ''E. japonica'' while the smaller i ...

Evynnis Cardinalis
''Evynnis cardinalis'', the threadfin porgy or cardinal seabream, is a species of marine ray-finned fish belonging to the family Sparidae, which includes the seabreams and porgies. This fish is found in the Western Pacific Ocean off the coasts of Eastern Asia. It is an important food fish but is classified by the IUCN as Endangered. Taxonomy ''Evynnis cardinalis'' was first formally described as ''Sparus cardinalis'' by the French naturalist Bernard Germain de Lacépède with its type locality given as China and Japan. In 1912 the American ichthyologists David Starr Jordan and William Francis Thompson proposed a new monospecific genus, ''Evynnis'', with ''S. cardinalis'' as its only species and as the designated type species of the genus. This genus 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 Sparidae, but the 5th edition of Fishes of the World does not recognis ...

Evynnis Ehrenbergii
''Evynnis ehrenbergii'' is a species of marine ray-finned fish belonging to the family Sparidae, which includes the seabreams and porgies. This species is found in the Eastern Atlantic Ocean and the Mediterranean Sea. Taxonomy ''Evynnis ehrenbergii'' was first formally described in 1830 as ''Pagrus ehrenbergii'' by the French zoologist Achille Valenciennes with its type locality given as the Mediterranean Sea off Egypt. The genus ''Evynnis'' 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 Sparidae, but the 5th edition of Fishes of the World does not recognise subfamilies within the Sparidae. Etymology ''Evynnis ehrenbergii'' has a specific name which honours Christian Gottfried Ehrenberg, the German biologist who first realised that this taxon was a different species from ''Argyrops spinifer'' from the Red Sea. Description ''Evynnis ehrenbergii'' has 11 or 12 spine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sparidae
Sparidae is a family of ray-finned fishes belonging to the order Spariformes, the seabreams and porgies, although they were traditionally classified in the order Perciformes. The over 150 species are found in shallow and deep marine waters in temperate through tropical regions around the world. Most species are demersal carnivores. Taxonomy Sparidae was first proposed as a family in 1818 by the French polymath and naturalist Constantine Samuel Rafinesque. Traditionally the taxa within the Spariformes were classified within the Perciformes, with some authorities using the term "Sparoid lineage" for the families Centracanthidae, Nemipteridae, Lethrinidae and Sparidae. Since then the use of molecular phylogenetics in more modern classifications has meant that the Spariformes is recognised as a valid order within the Percomorpha containing six families, with Callanthidae, Sillaginidae and Lobotidae included. Other workers have found that the Centracanthidae is synonymous with Spa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Total Length
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery 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. 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 (shark Sharks are a group of elasmobranch cartilaginous fish characterized by a ...

Anal Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish ( Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish ( Chondrichthyes) and jawless fish ( Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsal Fin
A dorsal fin is a fin on the back of most marine and freshwater vertebrates. Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous. They are found in most fish, in mammals such as whales, and in extinct ancient marine reptiles such as ichthyosaurs. Most have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of whales to identify individuals in the field. The bones or cartilages that support the dorsal fin in fish are called pterygiophores. Functions The main purpose of the dorsal fin is usually to stabilize the animal against rolling and to assist in sudden turns. Some species have further adapted their dorsal fins to other uses. The sunfish uses the dorsal fin (and the anal fin Fins are moving appendages protruding from the body of fish that interact with water to ge ...

Molar (tooth)
The molars or molar teeth are large, flat teeth at the back of the mouth. They are more developed in mammals. They are used primarily to grind food during chewing. The name ''molar'' derives from Latin, ''molaris dens'', meaning "millstone tooth", from ''mola'', millstone and ''dens'', tooth. Molars show a great deal of diversity in size and shape across the mammal groups. The third molar of humans is sometimes vestigial. Human anatomy In humans, the molar teeth have either four or five cusps. Adult humans have 12 molars, in four groups of three at the back of the mouth. The third, rearmost molar in each group is called a wisdom tooth. It is the last tooth to appear, breaking through the front of the gum at about the age of 20, although this varies among individuals and populations, and in many cases the tooth is missing. The human mouth contains upper (maxillary) and lower (mandibular) molars. They are: maxillary first molar, maxillary second molar, maxillary third mol ...

Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to Joseph Natterer gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the Rijksmuseum van Natuurlijke Historie, natural history museum of Leiden, who was seeking an ...

Coenraad Jacob Temminck
Coenraad Jacob Temminck (; 31 March 1778 – 30 January 1858) was a Dutch people, Dutch patrician, Zoology, zoologist and museum director. Biography Coenraad Jacob Temminck was born on 31 March 1778 in Amsterdam in the Dutch Republic. From his father, Jacob Temminck, who was treasurer of the Dutch East India Company with links to numerous travellers and collectors, he inherited a large collection of bird specimens. His father was a good friend of Francois Levaillant who also guided Coenraad. Temminck's ''Manuel d'ornithologie, ou Tableau systématique des oiseaux qui se trouvent en Europe'' (1815) was the standard work on European birds for many years. He was also the author of ''Histoire naturelle générale des Pigeons et des Gallinacées'' (1813–1817), illustrated by Pauline Rifer de Courcelles, Pauline Knip. He wrote ''Nouveau Recueil de Planches coloriées d'Oiseaux'' (1820–1839), and contributed to the mammalian sections of Philipp Franz von Siebold's ''Fauna jap ...
