Sticklebacks
The sticklebacks are a family of ray-finned fishes, the Gasterosteidae which have a Holarctic distribution in fresh, brackish and marine waters. They were thought to be related to the pipefish and seahorses but are now thought to be more closely related to the eelpouts and sculpins. Taxonomy The stickleback family, Gasterosteidae, was first proposed as a family by the French zoologist Charles Lucien Bonaparte in 1831. It was long though that the sticklebacks and their relatives made up a suborder, the Gasterosteoidei, of the order Gasterostiformes with the sea horses and pipefishes making up the suborder Syngnathoidei. More recent phylogenetic work has shown that the Gaterosteoidei is more closely related to the Zoarcoidei and the Cottoidei, which means that this taxon would belong in the order Scorpaeniformes. but in other phylogenetic classifications it is treated as the infraorder Gasterosteales within the suborder Cottoidei or as a sister clade to the Zoarcales in the order ...

Apeltes
''Apeltes'' is a monospecific genus old ray-finned fish belonging to the family Gasterosteidae, the sticklebacks. The only species in the genus is ''Apeltes quadracus'', the fourspine stickleback or bloody stickleback, which lives in freshwater, brackish and benthopelagic environments of the northwestern Atlantic Ocean between Newfoundland and South Carolina. Appearance The fourspine stickleback is the smallest member of the family Gasterosteidae. It generally has either four or five dorsal spines but may have as many as seven. It has an elongated fusiform body that is spotted brown to olive green except for the underside. Its belly is silvery white. Males tend to be dark than females and develop red pelvic spines. The first three dorsal spines are close together and stick out at acute angles, each with their own triangular membrane. The fourth spine is straight and associated with the dorsal fin. Its lateral line ends blow the origin of the second dorsal fin. Its pelvic fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasterosteoidei
Gasterosteoidei is a suborder of ray-finned fishes that includes the sticklebacks and relatives, the 5th edition of ''Fishes of the World'' classifies this suborder within the order Scorpaeniformes. Systematics Gasterosteoidei is treated as a suborder within the order Scorpaeniformes in the 5th edition of ''Fishes of the World'', but in other phylogenetic classifications it is treated as the infraorder Gasterosteales within the suborder Cottoidei or as a sister clade to the Zoarcales in the order Zoarciformes. Indostomidae is included within Gasterosteoidei in ''Fishes of the World but according to Betancur ''et al'' its inclusion in the clade renders it paraphyletic and they classify that family within the monotypic suborder Indostomoidei within the Synbranchiformes. Historically, Gasterosteoidei was treated as a suborder within the order Gasterostiformes and often included the sea horses, pipefishes and their relatives as suborder Syngnathoidei, with the sticklebacks and r ...

Culaea
} The brook stickleback (''Culaea inconstans'') is a small freshwater fish that is distributed across the US and Canada. It grows to a length of about 2 inches. It occupies the northern part of the eastern United States, as well as the southern half of Canada. Small populations are scattered throughout the Mississippi-Great Lakes basin extending to Colorado, New Mexico, Kentucky, Tennessee, etc., though some of these areas are not native to the species. This small fish inhabits clear, cool streams and lakes. They eat small invertebrates, algae, insect larvae, and occasionally their own eggs. They are also preyed upon by smallmouth bass and northern pike. Feeding time is usually dawn and sunset. The brook stickleback does have active competition mostly from minnows, but feeding times are different, along with diet.Stewart, D.B. 2007.''Fish diets and food webs in the Northwest Territories: brook stickleback (''Culaea inconstans'').

Eelpout
The eelpouts are the ray-finned fish family Zoarcidae. As the common name suggests, they are somewhat eel-like in appearance. All of the roughly 300 species are marine and mostly bottom-dwelling, some at great depths. Eelpouts are predominantly found in the Northern Hemisphere. The arctic, north pacific and north Atlantic oceans have the highest concentration of species, however species are found around the globe. They are conventionally placed in the "perciform" assemblage; in fact, the Zoarcoidei seem to be specialized members of the Gasterosteiformes-Scorpaeniformes group of Acanthopterygii. The largest member of the family is '' Zoarces americanus'', which may reach 1.1 m in length. Other notable genera include '' Lycodapus'' and '' Gymnelus''. Taxonomy The eelpout family was first proposed as the family Zoarchidae in 1839 by the English naturalist William John Swainson but the spelling was changed to Zoarcidae after the spelling of the genus Zoarces was corrected by The ...

Spinachia
''Spinachia'' is a monospecific genus of ray-finned fish belonging to the family Gasterosteidae, the sticklebacks. The only species in the genus is ''Spinachia spinachia'', the sea stickleback, fifteen-spined stickleback or fifteenspine stickleback, a species which lives in benthopelagic and in brackish environments of the northeastern Atlantic Ocean. This species, the largest of the sticklebacks, grows to a length of SL. This species is the only known member of its genus ''Spinachia''. It is of no interest as a commercial fish. Description The fifteen-spined stickleback is an elongated fish with a long slender snout, an elongated caudal peduncle about one third of the total length, and a fan-like rounded caudal fin. The anterior dorsal fin consists of a series of fourteen to fifteen small, widely separated spines. The posterior dorsal fin and the anal fin are aligned and are similar in size and shape and located immediately anterior to the caudal peduncle. The pelvic fins c ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea wit ...

Taxon
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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Georges Cuvier
Jean Léopold Nicolas Frédéric, Baron Cuvier (; 23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French naturalist and 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 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 catastrophic flooding events. In this way, ...
