Alepisauridae
Lancetfishes are large oceanic predatory fishes in the genus ''Alepisaurus'' ("scaleless lizard") in the monotypic taxon, monogeneric family Alepisauridae. Lancetfishes grow up to in length. Very little is known about their biology, though they are widely distributed in all oceans, except the polar region, polar seas. Specimens have been recorded as far north as Greenland. They are often caught as bycatch by vessels long-lining for tuna. The genus, generic name is from Greek language, Greek ''a-'' meaning "without", ' meaning "scale", and ''sauros'' meaning "lizard". Species The two currently recognized extant species in this genus are: * ''Alepisaurus brevirostris'' Robert Henry Gibbs, Gibbs, 1960 (short-snouted lancetfish) * ''Alepisaurus ferox'' Richard Thomas Lowe, R. T. Lowe, 1833 (long-snouted lancetfish) The anatomic difference between the two species is the shape of the snout, which is long and pointed in ''A. ferox'', and slightly shorter in ''A. brevirostris''.

Aulopiformes
Aulopiformes is a diverse order of marine ray-finned fish consisting of some 15 extant and several prehistoric families with about 45 genera and over 230 species. The common names grinners, lizardfishes and allies, or aulopiforms are sometimes used for this group. The scientific name means "''Aulopus''-shaped", from ''Aulopus'' (the type genus) + the standard fish order suffix "-formes". It ultimately derives from Ancient Greek ''aulós'' (αὐλός, "flute" or "pipe") + Latin ''forma'' ("external form"), the former in reference to the elongated shape of many aulopiforms.FishBase (2000) They are grouped together because of common features in the structure of their gill arches. Indeed, many authors have considered them so distinct as to warrant separation in a monotypic superorder of the Teleostei, under the name Cyclosquamata. However, monotypic taxa are generally avoided by modern taxonomists if not necessary, and in this case a distinct superorder seems indeed unwarra ...

Alepisaurus Ferox
''Alepisaurus ferox'', the long snouted lancetfish, longnose lancetfish, or cannibal fish, is a species of lancetfish found in the ocean depths down to 1,830 m (6,000 ft). This species grows to in total length and a weight of . It is often called the cannibal fish because numerous individuals have been caught after having devoured other lancetfish. Habitat and ecosystem Habitat ''A. ferox'' lives in deep-water oceans in the Western and Eastern Pacific from the Aleutian Islands to Chile and the Western Atlantic from the Gulf of Maine to the Gulf of Mexico, including the Caribbean Sea, and the Eastern Atlantic, Indian Ocean, Northwest Atlantic, and the China Sea. The ''A. ferox'' can also be found as far north as Russia. Due to the range of habitat the ''A. ferox'' can be found in, it can be caught with fisheries that are catching tuna. The daily vertical migrations from the epipelagic all the way down to the mesopelagic or bathypelagic zones are taken by the ''A. f ...

Alepisaurus Paronai
''Alepisaurus paronai'' is an extinct species of lancetfish known from a fossil skull found in Middle Miocene-aged strata in Piedmont, Italy. The skull is very similar in anatomy and dimensions to that of the extant long-snouted lancetfish. The specific name honors one Professor Carlo Fabrizio Parona, a friend and personal mentor of its describer, Geremia d'Erasmo. See also Other notable extinct Cenozoic aulopiforms include: *''Argillichthys'', a synodontid lizardfish from the Ypresian London Clay *''Polymerichthys'', a closely related alepisauroid from Middle Miocene Japan Japan ( ja, 日本, or , and formally , ''Nihonkoku'') is an island country in East Asia.

William John Swainson
William John Swainson FLS, FRS (8 October 1789 – 6 December 1855), was an English ornithologist, malacologist, conchologist, entomologist and artist. Life Swainson was born in Dover Place, St Mary Newington, London, the eldest son of John Timothy Swainson the Second (1756–1824), an original fellow of the Linnean Society. He was cousin of the amateur botanist Isaac Swainson.Etymologisches Worterbuch der botanischen Pflanzennamen by H. Genaust. Review by Paul A. Fryxell ''Taxon'', Vol. 38(2), 245–246 (1989). His father's family originated in Lancashire, and both grandfather and father held high posts in Her Majesty's Customs, the father becoming Collector at Liverpool. William, whose formal education was curtailed because of an impediment in his speech, joined the Liverpool Customs as a junior clerk at the age of 14."William Swainson F.R.S, F.L.S., Naturalist and Artist: Diaries 1808–1838: Sicily, Malta, Greece, Italy and Brazil."

Caudal 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 lu ...

Teeth
A tooth ( : teeth) is a hard, calcified structure found in the jaws (or mouths) of many vertebrates and used to break down food. Some animals, particularly carnivores and omnivores, also use teeth to help with capturing or wounding prey, tearing food, for defensive purposes, to intimidate other animals often including their own, or to carry prey or their young. The roots of teeth are covered by gums. Teeth are not made of bone, but rather of multiple tissues of varying density and hardness that originate from the embryonic germ layer, the ectoderm. The general structure of teeth is similar across the vertebrates, although there is considerable variation in their form and position. The teeth of mammals have deep roots, and this pattern is also found in some fish, and in crocodilians. In most teleost fish, however, the teeth are attached to the outer surface of the bone, while in lizards they are attached to the inner surface of the jaw by one side. In cartilaginous fish, s ...

Lobe (anatomy)
In anatomy, a lobe is a clear anatomical division or extension of an organ (as seen for example in the brain, lung, liver, or kidney) that can be determined without the use of a microscope at the gross anatomy level. This is in contrast to the much smaller lobule, which is a clear division only visible under the microscope. Interlobar ducts connect lobes and interlobular ducts connect lobules. Examples of lobes *The four main lobes of the brain **the frontal lobe **the parietal lobe **the occipital lobe **the temporal lobe *The three lobes of the human cerebellum **the flocculonodular lobe **the anterior lobe **the posterior lobe *The two lobes of the thymus *The two and three lobes of the lungs **Left lung: superior and inferior **Right lung: superior, middle, and inferior *The four lobes of the liver **Left lobe of liver **Right lobe of liver **Quadrate lobe of liver **Caudate lobe of liver *The renal lobes of the kidney *Earlobes Examples of lobules *the cortical lobules o ...

Fork
In cutlery or kitchenware, a fork (from la, furca 'pitchfork') is a utensil, now usually made of metal, whose long handle terminates in a head that branches into several narrow and often slightly curved tines with which one can spear foods either to hold them to cut with a knife or to lift them to the mouth. History Bone forks have been found in archaeological sites of the Bronze Age Qijia culture (2400–1900 BC), the Shang dynasty (c. 1600–c. 1050 BC), as well as later Chinese dynasties.Needham (2000). ''Science and Civilisation in China. Volume 6: Biology and biological technology. Part V: Fermentations and food science.'' Cambridge University Press. Pages 105–110. A stone carving from an Eastern Han tomb (in Ta-kua-liang, Suide County, Shaanxi) depicts three hanging two-pronged forks in a dining scene. Similar forks have also been depicted on top of a stove in a scene at another Eastern Han tomb (in Suide County, Shaanxi). In Ancient Egypt, large forks were used as ...

Fish Anatomy
Fish anatomy is the study of the form or morphology of fish. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish. In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in living fish. The anatomy of fish is often shaped by the physical characteristics of water, the medium in which fish live. Water is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs more light than air does. The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish, is either made of cartilage ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
