Cetopsis Coecutiens
''Cetopsis coecutiens'', the ''candiru-açú'', ''piracatinga'', ''bagre ciego'' (Literal translation, lit. blind catfish), or the blue whale catfish, is a species of catfish found throughout the Amazon basin in Bolivia, Brazil, Colombia, Peru and Venezuela. The fish was first described by Hinrich Lichtenstein in 1819, who named it for its resemblance to certain cetaceans. ''C. coecutiens'' is one of the largest species of "candiru" catfish. While these catfish are reported to grow to a size of , some specimens greater than have been caught in the wild. ''Cetopsis coecutiens'', like its Sister group, sister species ''Cetopsis candiru, C. candiru'', is a carnivorous fish and commonly described as a voracious feeder, making use of powerful jaw musculature and a nearly continuous cutting surface of the incisiform dentition. The distributions of both species overlap and both ''Cetopisis'' species are known to simultaneously feed on the same Carrion, bodies. They do however differ in ...

Literal Translation
Literal translation, direct translation, or word-for-word translation is the translation of a text done by translating each word separately without analysing how the words are used together in a phrase or sentence. In translation theory, another term for literal translation is ''metaphrase'' (as opposed to ''paraphrase'' for an analogous translation). It is to be distinguished from an Language interpretation, interpretation (done, for example, by an interpreter). Literal translation leads to mistranslation of idioms, which can be a serious problem for machine translation. Translation studies Usage The term "literal translation" often appeared in the titles of 19th-century English translations of the classical Bible and other texts. Cribs Word-for-word translations ("cribs", "ponies", or "trots") are sometimes prepared for writers who are translating a work written in a language they do not know. For example, Robert Pinsky is reported to have used a literal translation in prep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carrion
Carrion (), also known as a carcass, is the decaying flesh of dead animals. Overview Carrion is an important food source for large carnivores and omnivores in most ecosystems. Examples of carrion-eaters (or scavengers) include crows, vultures, humans, hawks, eagles, hyenas, Virginia opossum, Tasmanian devils, coyotes and Komodo dragons. Many invertebrates, such as the Silphidae, carrion and burying beetles, as well as maggots of Calliphoridae, calliphorid flies (such as one of the most important species in ''Calliphora vomitoria'') and Flesh-fly, flesh-flies, also eat carrion, playing an important role in recycling nitrogen and carbon in animal remains. Carrion begins to decay at the moment of the animal's death, and it will increasingly attract insects and breed bacteria. Not long after the animal has died, its body will begin to exude a foul odor caused by the presence of bacteria and the emission of cadaverine and putrescine. Carrion can harbor many infectious and diseas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gillnets
Gillnetting is a fishing method that uses gillnets: vertical panels of netting that hang from a line with regularly spaced floaters that hold the line on the surface of the water. The floats are sometimes called "corks" and the line with corks is generally referred to as a "cork line." The line along the bottom of the panels is generally weighted. Traditionally this line has been weighted with lead and may be referred to as "lead line." A gillnet is normally set in a straight line. Gillnets can be characterized by mesh size, as well as colour and type of filament from which they are made. Fish may be caught by gillnets in three ways: # Wedged – held by the mesh around the body. # Gilled – held by mesh slipping behind the opercula. # Tangled – held by teeth, spines, maxillaries, or other protrusions without the body penetrating the mesh. Most fish have gills. A fish swims into a net and passes only part way through the mesh. When it struggles to free itself ...

Cadaver
A cadaver, often known as a corpse, is a Death, dead human body. Cadavers are used by medical students, physicians and other scientists to study anatomy, identify disease sites, determine causes of death, and provide tissue (biology), tissue to repair a defect in a living human being. Students in medical school study and dissect cadavers as a part of their education. Others who study cadavers include archaeologists and arts students. In addition, a cadaver may be used in the development and evaluation of surgical instruments. The term ''cadaver'' is used in courts of law (and, to a lesser extent, also by media outlets such as newspapers) to refer to a dead body, as well as by recovery teams searching for bodies in natural disasters. The word comes from the Latin word ''cadere'' ("to fall"). Related terms include ''cadaverous'' (resembling a cadaver) and ''cadaveric spasm'' (a muscle spasm causing a dead body to twitch or jerk). A cadaver graft (also called “postmortem graft”) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forensics
Forensic science combines principles of law and science to investigate criminal activity. Through crime scene investigations and laboratory analysis, forensic scientists are able to link suspects to evidence. An example is determining the time and cause of death through autopsies. This evidence can then be used for proof towards a crime. Forensic science, often confused with criminalistics, is the application of science principles and methods to support legal decision-making in matters of criminal and civil law. During criminal investigation in particular, it is governed by the legal standards of admissible evidence and criminal procedure. It is a broad field utilizing numerous practices such as the analysis of DNA, fingerprints, bloodstain patterns, firearms, ballistics, toxicology, microscopy, and fire debris analysis. Forensic scientists collect, preserve, and analyze evidence during the course of an investigation. While some forensic scientists travel to the scene of t ...

Scavenger
Scavengers are animals that consume Corpse decomposition, dead organisms that have died from causes other than predation or have been killed by other predators. While scavenging generally refers to carnivores feeding on carrion, it is also a herbivorous feeding behavior. Scavengers play an important role in the ecosystem by consuming dead animal and plant material. Decomposer, ''Decomposers'' and detritivores complete this process, by consuming the remains left by scavengers. Scavengers aid in overcoming fluctuations of food resources in the environment. The process and rate of scavenging is affected by both Biotic component, biotic and Abiotic component, abiotic factors, such as carcass size, habitat, temperature, and seasons. Etymology Scavenger is an alteration of ''scavager,'' from Middle English ''skawager'' meaning "customs collector", from ''skawage'' meaning "customs", from Old North French ''escauwage'' meaning "inspection", from ''schauwer'' meaning "to inspect", of ...

Eyeball
An eye is a sensory organ that allows an organism to perceive visual information. It detects light and converts it into electro-chemical impulses in neurons (neurones). It is part of an organism's visual system. In higher organisms, the eye is a complex optical Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultravio ... system that collects light from the surrounding environment, regulates its intensity through a Iris (anatomy), diaphragm, Focus (optics), focuses it through an adjustable assembly of Lens (anatomy), lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain.

Cartilage
Cartilage is a resilient and smooth type of connective tissue. Semi-transparent and non-porous, it is usually covered by a tough and fibrous membrane called perichondrium. In tetrapods, it covers and protects the ends of long bones at the joints as articular cartilage, and is a structural component of many body parts including the rib cage, the neck and the bronchial tubes, and the intervertebral discs. In other taxa, such as chondrichthyans and cyclostomes, it constitutes a much greater proportion of the skeleton. It is not as hard and rigid as bone, but it is much stiffer and much less flexible than muscle. The matrix of cartilage is made up of glycosaminoglycans, proteoglycans, collagen fibers and, sometimes, elastin. It usually grows quicker than bone. Because of its rigidity, cartilage often serves the purpose of holding tubes open in the body. Examples include the rings of the trachea, such as the cricoid cartilage and carina. Cartilage is composed of specialized c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cetopsis Candiru
''Cetopsis candiru'', also known as candiru, candiru açú, candiru cobra or canero, is a carnivorous species of whale catfish found in the Amazon basin of Peru, Brazil and Bolivia. Similar to ''Cetopsis coecutiens'', ''Cetopsis candiru'' is a large species of the genus ''Cetopsis'' and a widespread scavenger, known for its voracious feeding and the habit of burrowing into the carcasses of dead animals and humans. Despite its name, it is not closely related to the bloodsucking Candiru (''Vandellia cirrhosa''). Names They are known by multiple names across their range. In Bolivia they are called "Canero" or just "Candiru". The term "Canero" is also used in Peru. Candiru açú is also used on occasion, however according to some researchers this name is primarily used for other species of the genus ''Cetopsis'' including ''C. coecutiens'' and ''C. gobioides''. Alternatively the name "candiru cobra" is also used. The name Candiru is shared by ''Vandellia cirrhosa'', a parasitic ca ...

Amazon Basin
The Amazon basin is the part of South America drained by the Amazon River and its tributary, tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela, as well as the territory of French Guiana. Most of the basin is covered by the Amazon rainforest, also known as Amazon rainforest, Amazonia. With a area of dense tropical forest, it is the largest rainforest in the world. Geography The Amazon River begins in the Andes, Andes Mountains at the west of the basin with its main tributary the Marañón River and Apurímac River, Apurimac River in Peru. The highest point in the Drainage divide, watershed of the Amazon is the second biggest peak of Yerupajá at .

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxono ...

Hinrich Lichtenstein
Martin H[e]inrich Carl Lichtenstein (10 January 1780 – 2 September 1857) was a German physician, List of explorers, explorer, botanist and zoologist. He explored parts of southern Africa and collected natural history specimens extensively and many new species were described from his collections by European scientists. Biography Born in Hamburg, Lichtenstein was the son of Anton August Heinrich Lichtenstein, head of the Gelehrtenschule des Johanneums, Johanneum. His father had an interest in eastern languages and built up an extensive library. He took an interest in natural history and geography from an early age, and came into contact with Count Johann Centurius Hoffmannsegg, Johann Centurius von Hoffmannsegg in 1797 and began to help examine the Count's extensive collections of insects and birds. He then went to study medicine at University of Jena, Jena and University of Helmstedt, Helmstedt and qualified as a doctor on 26 April 1802. He then chose to travel and found work ...
