Ophichthidae
Ophichthidae is a family of fish in the order Anguilliformes, commonly known as the snake eels. The term "Ophichthidae" comes from Greek ''ophis'' ("serpent") and ''ichthys'' ("fish"). Snake eels are also burrowing eels. They are named for their physical appearance, as they have long, cylindrical, snake-like bodies. This family is found worldwide in tropical to warm temperate waters. They inhabit a wide range of habitats, from coastal shallows and even rivers, to depths below . Most species are bottom dwellers, hiding in mud or sand to capture their prey of crustaceans and small fish, but some are pelagic. These species range in total length from to or more. Many species lack fins altogether, improving their ability to burrow into the substrate like worms. They are often spotted or striped in colour, mimicking the appearance of venomous sea snakes to deter predators. Often, they are washed ashore by large storms. Genera Currently, 62 recognized genera are placed in this fami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Cadenat
Jean Cadenat (born Marmande, Lot-et-Garonne 16 April 1908, died Marmande 28 June 1992) was a French ichthyologist. In 1930, he joined the Agricultural Zoology station at La Grand Ferrade as an assistant preparator and the following year he completed his BSc (''license'') at the University of Bordeaux. From January 1932 to December 1941 he was at La Rochelle as an assistant in the Laboratory of G. Belloc at the Scientific and Technical Office of Fisheries then headed by Edouard Le Danois. During this period, he participated in many research expeditions, firstly aboard trawlers to the coasts of Ireland, France, Spain, Morocco and Mauritania, as well as participating in the fifth scientific cruise of the ''President Theodore Tissier'' in 1936 which travelled from the Canary Islands to the coast of Sierra Leone. In 1934, he began his military service in the French Navy, serving aboard Fisheries Patrols. In 1939, he was mobilised back to active service in La Rochelle. When he was demobil ...

Tropical
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the Season, solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions of Earth, polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Biology
Marine biology is the scientific study of the biology of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy. A large proportion of all life on Earth lives in the ocean. The exact size of this ''large proportion'' is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world covering approximately 71% of the Earth's surface. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10,000 meters or more beneath the surface of the ocean. Specific habitats include estuaries, coral reefs, kelp forests, seagrass meadows, the surrounds of seamounts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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#Surface, 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 Earth, the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North America, 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 8th paralle ...

Total Length
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries 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. Simply put, 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 (sharks and rays), as well as some other fishes.

African Wedgefish
The African wedgefish, guitarra, Lubbert's guitarfish, or spikenose wedgefish (''Rhynchobatus luebberti'') is a species of fish in the Rhinidae family. It is the only species in its genus to occur in the East Atlantic. Etymology The fish is named in honor of Hans Julius L眉bbert (1870-1951), a German fisheries inspector. Taxonomy Description African wedgefish have a pale olive-brown or olive-grey color with white spots spread across their back. The edges of their fins are sometimes paler in color. They have a cluster of three black marks on each side of a ridge that runs along their back. Another dark mark can be found each one of these marks. The area around each fish's eye is lighter, reminiscent of a mask. The fish have ridges near their front that possess a row of thorns. The African wedgefish has a maximum total length of about 3 m (9.8 ft), but are usually 1.5 m (4.9 ft) long. They have 172-176 free vertebral centra. Distribution and habitat T ...

Fish Of The Atlantic Ocean
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fi ...
