Context: Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus., A genus ( genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus., Labroides is a genus of wrasses native to the Indian and Pacific Oceans . This genus is collectively known as cleaner wrasses and its species are cleaner fish ., Skin is the soft outer covering of vertebrates. Other animal coverings, such as the arthropod exoskeleton have different developmental origin, structure and chemical composition. The adjective cutaneous means "of the skin" (from Latin "cutis", skin). In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue, and guards the underlying muscles, bones, ligaments and internal organs. Skin of a different nature exists in amphibians, reptiles, and birds. All mammals have some hair on their skin, even marine mammals like whales, dolphins, and porpoises which appear to be hairless.
The skin interfaces with the environment and is the first line of defense from external factors. For example, the skin plays a key role in protecting the body against pathogens and excessive water loss. Its other functions are insulation, temperature regulation, sensation, and the production of vitamin D folates. Severely damaged skin may heal by forming scar tissue. This is sometimes discoloured and depigmented. The thickness of skin also varies from location to location on an organism. In humans for example, the skin located under the eyes and around the eyelids is the thinnest skin in the body at 0.5 mm thick, and is one of the first areas to show signs of aging such as "crows feet" and wrinkles. The skin on the palms and the soles of the feet is 4 mm thick and the back is 14 mm thick and is the thickest skin in the body. The speed and quality of wound healing in skin is promoted by the reception of estrogen., In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs., Cleaner shrimp is a common name for a number of swimming decapod crustaceans that clean other organisms of parasites. They belong to any of three families, Hippolytidae (including the Pacific cleaner shrimp, "Lysmata amboinensis"), Palaemonidae (including the spotted "Periclimenes magnificus") and Stenopodidae (including the banded coral shrimp, "Stenopus hispidus") . The last of these families is more closely related to lobsters and crabs than it is to the remaining families. The term "cleaner shrimp" is sometimes used more specifically for the family Hippolytidae and the genus "Lysmata"., Cichlids are fish from the family Cichlidae in the order Perciformes. Cichlids are members of a suborder known as Labroidei, along with the wrasses (Labridae), damselfishes (Pomacentridae), and surfperches (Embiotocidae). This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Cichlids are popular freshwater fish kept in the home aquarium., Cleaner fish are fish that provide a service to other fish species by removing dead skin and ectoparasites. This cleaning symbiosis is an example of mutualism, an ecological interaction that benefits both parties involved. However, the cleaner fish may sometimes cheat and consume mucus or tissue, thus creating a form of parasitism. A wide variety of fish including wrasse, cichlids, catfish, pipefish, and gobies display cleaning behaviors. Similar behavior is found in other groups of animals, such as cleaner shrimps., Pipefishes or pipe-fishes (Syngnathinae) are a subfamily of small fishes, which, together with the seahorses and seadragons, form the family Syngnathidae., The wrasses are a family, Labridae, of marine fish, many of which are brightly colored. The family is large and diverse, with over 600 species in 82 genera, which are divided into 9 subgroups or tribes.
They are typically small fish, most of them less than long, although the largest, the humphead wrasse, can measure up to . They are efficient carnivores, feeding on a wide range of small invertebrates. Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing. Juveniles of some representatives of the genera "Bodianus", "Epibulus","Cirrhilabrus", "Oxycheilinus", and "Paracheilinus" hide among the tentacles of the free-living mushroom coral "Heliofungia actiniformis"., In biology/ecology, parasitism is a non-mutual relationship between species, where one species, the parasite, benefits at the expense of the other, the host. Traditionally "parasite" (in biological usage) referred primarily to organisms visible to the naked eye, or macroparasites (such as helminths). Parasites can be microparasites, which are typically smaller, such as protozoa, viruses, and bacteria. Examples of parasites include the plants mistletoe and cuscuta, and animals such as hookworms., A fish is any member of a group of organisms that consist of all gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered obsolete or paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry). Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology. The traditional term pisces (also ichthyes) is considered a typological, but not a phylogenetic classification., Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia and the Piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, "Vandellia cirrhosa". There are armour-plated types and there are also naked types, neither having scales. Despite their name, not all catfish have prominent barbel. Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus "Corydoras", are important in the aquarium hobby. Many catfish are nocturnal, but others (many "Auchenipteridae") are "crepuscular" or "diurnal" (most "Loricariidae or" "Callichthyidae" for example)., Subject: labroides, Relation: parent_taxon, Options: (A) animal (B) areas (C) cichlidae (D) corydoras (E) cuscuta (F) embiotocidae (G) hagfish (H) hippolytidae (I) homo (J) labridae (K) labroidei (L) lysmata (M) olfactores (N) palaemonidae (O) perciformes (P) pipefish (Q) plant (R) pomacentridae (S) protozoa (T) siluriformes (U) stenopodidae (V) stenopus (W) syngnathidae (X) vandellia

Context: A string band is an old-time music or jazz ensemble made up mainly or solely of string instruments. String bands were popular in the 1920s and 1930s, and are among the forerunners of modern country music and bluegrass., The Red Fox Chasers were a string band that formed in North Carolina in 1927, and were active until around 1931. Members included vocalist and guitar player A. P. Thompson, vocalist and harmonica player Bob Cranford, vocalist and banjo player Paul Miles, and fiddler Guy Brooks., Guy Brooks was a fiddle player for the late 1920s early 1930s string band The Red Fox Chasers . He played classic old time music ., A.P. Thompson was the lead vocalist and guitar player for the late 1920s early 1930s string band The Red Fox Chasers., Fiddle is another name for the bowed string musical instrument more often called a violin. It is also a colloquial term for the instrument used by players in all genres, including classical music. Fiddle playing, or fiddling, refers to various styles of music. Fiddle is also a common term among musicians who play folk music on the violin. The fiddle is part of many traditional (folk) styles of music which are aural traditions, taught 'by ear' rather than via written music. Fiddle is normally the term used for Irish Traditional Music., The violin is a wooden string instrument in the violin family. It is the smallest and highest-pitched instrument in the family in regular use. Smaller violin-type instruments are known, including the violino piccolo and the kit violin, but these are virtually unused in the 2010s. The violin typically has four strings tuned in perfect fifths, and is most commonly played by drawing a bow across its strings, though it can also be played by plucking the strings with the fingers (pizzicato). Violins are important instruments in a wide variety of musical genres. They are most prominent in the Western classical tradition and in many varieties of folk music. They are also frequently used in genres of folk including country music and bluegrass music and in jazz. Electric violins are used in some forms of rock music; further, the violin has come to be played in many non-Western music cultures, including Indian music and Iranian music. The violin is sometimes informally called a fiddle, particularly in Irish traditional music and bluegrass, but this nickname is also used regardless of the type of music played on it., Folk music includes both traditional music and the genre that evolved from it during the 20th century folk revival. The term originated in the 19th century but is often applied to music that is older than that. Some types of folk music are also called world music. "Traditional folk music" has been defined in several ways: as music transmitted orally, music with unknown composers, or music performed by custom over a long period of time. It has been contrasted with commercial and classical styles., Bob Cranford was a vocalist and harmonica player for the late 1920s and early 1930s string band The Red Fox Chasers., Subject: guy brooks, Relation: occupation, Options: (A) band (B) commercial (C) drawing (D) fiddler (E) vocalist
