Galeichthys Feliceps
''Galeichthys feliceps'', the white barbel, sea barbel, white baggar or white sea catfish, is a species of sea catfish found in coastal waters and estuaries over muddy bottoms at depths of from 1 – 120 metres where they gather in large shoals. They occur from Namibia to South Africa with questionable records of sightings from Madagascar and Mozambique in Africa and the United States of America and Mexico in North America. It is coloured brown, grey or greenish-brown on the upperparts and is paler below. While most grow to a length of 35 cm, some individuals attain a length of 55 cm with a record of a fish from South Africa weighing 3.8 kg. The white barbel is a mouthbrooder as are the other members of this family. The female lays approximately 50 relatively large (15–16 mm diameter) eggs which the male carries in his mouth for about three to four months. During this time the male does not feed and can lose nearly one quarter of his body weight. The adul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sea Catfish
The Ariidae or ariid catfish are a family of catfish that mainly live in marine waters with many freshwater and brackish water species. They are found worldwide in tropical to warm temperate zones. The family includes about 143 species. Taxonomy The relationships of this family are not yet clear. Two of the genera, '' Gogo'' and '' Ancharius'', have been moved to a separate family called Anchariidae. The Ariidae are divided into three subfamilies: ''Galeichthys'' is the only genus classified in the subfamily Galeichthyinae and similarly '' Bagre'' is the only genus in the subfamily Bagreinae, while the rest of the genera are classified in the subfamily Ariinae. Previously, the family Ariidae has been grouped in the superfamily Doradoidea, but then it was moved into Bagroidea (along with Austroglanididae, Claroteidae, Schilbeidae, Pangasiidae, Bagridae, Malapteruridae, and Pimelodidae. It has also been classified in a superfamily Arioidea containing Ariidae and Anchariidae. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "'' Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of Ecuador
Ecuador ( ; ; Quechua: ''Ikwayur''; Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechua: ''Ikwadur Ripuwlika''; Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as its own sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its millio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of South Africa
The fauna of South Africa is diverse and largely typical of the ecosystems in Africa. South Africa is ranked sixth out of the world's 17 megadiverse countries. Many endemic species are unique to South Africa. The country is among the world leaders in conservation, but at the time wildlife is threatened by poaching and canned hunting. Habitats The topography and geology of South Africa is extremely varied, resulting in a wide variety of habitats. Due to this, South Africa enjoys high biodiversity, and is ranked sixth out of the world's seventeen megadiverse countries. In the extreme northwest of the country is true desert, which is the southernmost end of the Namib desert, a desert that is at least 55 million years old, making it the oldest desert in the world. This arid corner intergrades into the extensive semi-arid Karoo found across much of South Africa, covering the Northern Cape and into parts of the Western Cape, Eastern Cape and the Free State. This biome used to be extens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of Peru
Peru has some of the greatest biodiversity in the world. It belongs to the select group of mega diverse countries because of the presence of the Andes, Amazon rainforest, and the Pacific Ocean. It has the fourth-most tropical forests of any country and the ninth-most forest area. Natural protected areas The Constitution of Peru of 1993 recognized the natural resources and ecosystem variety of its country as a heritage. In 1900, the National System of Natural Areas that are protected by the Peruvian Government (SINANPE) was created. This entity depends on the National Institute of Natural Resources (INRENA). They also created a map of protection and preservation of historical - cultural heritage and nature. This map has 49 Natural Areas (10% of the country surface) that are preserved by the Government: 8 National Parks, 8 National Reservations, 6 National Sanctuaries, 3 Historical Sanctuaries, 4 National Forests, 6 Protection Forests, 1 Communal Reservation, 2 Hunting enclosed l ...

Adipose Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to ...
