King Mackerel
The king mackerel (''Scomberomorus cavalla'') surmayi or kingfish, is a migratory species of mackerel of the western Atlantic Ocean and Gulf of Mexico. It is an important species to both the commercial and recreational fishing industries. Description The king mackerel is a medium-sized fish, typically encountered from to , but is known to exceed . The entire body is covered with very small, hardly visible, loosely attached scales. The first (spiny) dorsal fin is entirely colorless and is normally folded back into a body groove, as are the pelvic fins. The lateral line starts high on the shoulder, dips abruptly at mid-body and then continues as a wavy horizontal line to the tail. Coloration is olive on the back, fading to silver with a rosy iridescence on the sides, fading to white on the belly. Fish under show yellowish-brown spots on the flanks, somewhat smaller than the spots of the Atlantic Spanish mackerel, ''Scomberomorus maculatus''. Its cutting-edged teeth are large, u ...

Georges Cuvier
Jean Léopold Nicolas Frédéric, baron Cuvier (23 August 1769 – 13 May 1832), known as Georges Cuvier (; ), was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastr ...

Gulf Stream
The Gulf Stream is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and flows through the Straits of Florida and up the eastern coastline of the United States, then veers east near 36°N latitude (North Carolina) and moves toward Northwest Europe as the North Atlantic Current. The process of western intensification causes the Gulf Stream to be a northward-accelerating current off the east coast of North America. Around , it splits in two, with the northern stream, the North Atlantic Drift, crossing to Northern Europe and the southern stream, the Canary Current, recirculating off West Africa. The Gulf Stream influences the climate of the coastal areas of the East Coast of the United States from Florida to southeast Virginia (near 36°N latitude), and to a greater degree, the climate of Northwest Europe. A consensus exists that the climate of Northwest Europe is warmer than other areas of similar latitude at least partially because of the stron ...

Blue Runners
The blue runner (''Caranx crysos''), also known as the bluestripe jack, Egyptian scad, hardtail jack or hardnose, is a common species of moderately large marine (ocean), marine fish classified in the jack Family (biology), family, Carangidae. The blue runner is distributed across the Atlantic Ocean, ranging from Brazil to Canada in the western Atlantic and from Angola to Great Britain including the Mediterranean in the east Atlantic. The blue runner is distinguished from similar species by several morphological features, including the extent of the upper jaw, gill raker count and lateral line scale counts. The blue runner is known to reach a maximum length of 70 cm and 5.05 kg in weight, but is much more common below 35 cm. The species inhabits both inshore and offshore environments, predominantly over reefs, however it is known to congregate around large, man-made, offshore structures such as oil platforms. Juveniles tend to inhabit shallower reef and lagoon waters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 16 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. Taxonomy Anchovies are classified into two subfamilies and 16 genera: * Superfamily Engrauloidea ** Genus †'' Clupeopsis'' Casier, 1946 ** Genus †''Monosmilus'' Capobianco et al, 2020 ** Family Engraulidae Gill, 1861 *** Subfamily Engraulinae Gill, 1861 **** Genus ''Amazonsprattus'' Roberts, 1984 **** Genus ''Anchoa'' D. S. Jordan & Evermann, 1927 **** Genus ''Anchovia'' D. S. Jordan & Evermann, 1895 **** Genus ''Anchoviella'' Fowler, 1911 **** Genus ''Cetengraulis'' Günther, 1868 **** Genus ''Encrasicholina'' Fowler, 1938 **** Genus †'' Eoengraulis'' Marrama & Ca ...

Haemulidae
Haemulidae is a family (biology), family of fishes in the order (biology), order Perciformes known commonly as grunts. It is made up of the two subfamily, subfamilies Haemulinae (grunts) and Plectorhynchinae (sweetlips), which contain about 133 species in 19 genera around the world. These fishes are commonly found in tropical, subtropical, and warm temperate regions, inhabiting marine, brackish, and sometimes fresh waters. The family shows many feeding adaptations from bottom-feeding predation to water-column planktivory and is named for the ability of Haemulinae to produce sounds by grinding their pharyngeal teeth. Some species engage in mutualistic relationships with cleaner gobies of the genus ''Elacatinus'', allowing them to feed on ectoparasites on their bodies. Subfamilies and genera The family Haemulidae is divided into the following subfamilies and genera: * Haemulinae ** ''Anisotremus'' Gill 1861 ** ''Boridia'' Georges Cuvier, Cuvier, 1830 ** ''Brachydeuterus'' Gill, ...

Sciaenidae
Sciaenidae is a family (biology), family of ray-finned fishes belonging to the Order (biology), order Acanthuriformes. They are commonly called drums or croakers in reference to the repetitive throbbing or drumming sounds they make. The family consists of about 293 to 298 species in about 66 or 67 genera. Taxonomy Sciaenidae was first proposed as a family in 1829 by the French zoologist Georges Cuvier. The 5th edition of ''Fishes of the World'' classifies the family in the suborder Sciaenoidei, alongside the rover family Emmelichthyidae, in the order Acanthuriformes. Other authorities classify the Sciaenidae and the Emmelichthyidae as ''incertae sedis'' within the series Eupercaria. The ''Catalog of Fishes'' retains this family within the Acanthuriformes but does not recognise the suborder Sciaenoidei. The 5th edition of ''Fishes of the World'', ''FishBase, Fishbase'' and ''Catalog of Fishes'' do not recognise Subfamily, subfamilies within the Sciaenidae but many workers on these ...

Weakfish
''Cynoscion'' is a genus of marine ray-finned fishes belonging to the family, Sciaenidae, the drums and croakers. These fishes are found off the coasts of North and South America in the western Atlantic and eastern Pacific Oceans. Many fishes in this genus have been given the common name weakfish. Taxonomy ''Cynoscion'' was first proposed as a monospecific genus in 1861 by the American biologist Theodore Gill with ''Johnnius regalis'', a species originally described in 1801 from New York by Marcis Elieser Bloch and Johann G. T. Schneider, designated as its type species. This genus has been placed in the subfamily Cynoscioninae by some workers, but the 5th edition of '' Fishes of the World'' does not recognise subfamilies within the Sciaenidae which it places in the order Acanthuriformes. Etymology ''Cynoscion'' is a combination of ''cyno'', meaning "dog", a reference to the pair of canine-like teeth in the upper jaw, with ''scion'', the modern Greek name of '' Umbrina cirr ...

Cutlassfish
The cutlassfishes are about 45 species of predatory ray-finned fish in the family Trichiuridae of the order Scombriformes found in seas throughout the world. Fish of this family are long, slender, and generally steely blue or silver in colour, giving rise to their name. They have reduced or absent pelvic fin, pelvic and caudal fins, giving them an eel-like appearance, and large fang-like teeth. Some of the species are known as scabbardfishes or hairtails; others are called frostfishes because they appear in late autumn and early winter, around the time of the first frosts. The earliest known remains of cutlassfish are isolated teeth assigned to ''Eutrichiurides'' from the Danian, Early Paleocene of Morocco, the United States, and Angola, although their affinities are subject to question. The earliest known body fossil of a cutlassfish is a specimen tentatively assigned to ''Anenchelum'' from the Ypresian, Early Eocene of Italy. Classification This list of species follows FishB ...

Carangidae
The Carangidae are a family of ray-finned fish that includes the jacks, pompanos, jack mackerels, runners, trevallies, and scads. It is the largest of the six families included within the order Carangiformes. Some authorities classify it as the only family within that order but molecular and anatomical studies indicate that there is a close relationship between this family and the five former Perciform families which make up the Carangiformes. They are marine fishes found in the Atlantic, Indian and Pacific Oceans. Most species are fast-swimming predatory fishes that hunt in the waters above reefs and in the open sea; some dig in the sea floor for invertebrates. The largest fish in the family, the greater amberjack, ''Seriola dumerili'', grows up to 2 m in length; most fish in the family reach a maximum length of 25–100 cm. The family contains many important commercial and game fish, notably the Pacific jack mackerel, ''Trachurus symmetricus'', and the other jack ...

Clupeidae
Clupeidae is a family of clupeiform ray-finned fishes, comprising, for instance, the herrings and sprats. Many members of the family have a body protected with shiny cycloid (very smooth and uniform) scales, a single dorsal fin, and a fusiform body for quick, evasive swimming and pursuit of prey composed of small planktonic animals. Due to their small size and position in the lower trophic level of many marine food webs, the levels of methylmercury they bioaccumulate are very low, reducing the risk of mercury poisoning when consumed. The earliest known fossil members of this group are the stem-clupeids '' Italoclupea'' and '' Lecceclupea'' from the late Campanian/early Maastrichtian of Italy.'''' Description and biology Clupeids are mostly marine forage fish, although a few species are found in fresh water. No species has scales on the head, and some are entirely scaleless. The lateral line is short or absent, and the teeth are unusually small where they are present at all. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
