Input: Consider Input: Context: Randall William "Randy" Rhoads (December 6, 1956  March 19, 1982) was an American heavy metal guitarist who played with Ozzy Osbourne and Quiet Riot. A devoted student of classical guitar, Rhoads combined his classical music influences with his own heavy metal style. He died in a plane accident while on tour with Osbourne in Florida in 1982. Despite his short career, Rhoads, who was a major influence on neoclassical metal, is cited as an influence by many guitarists and is included in several "Greatest Guitarist" lists., Uli Jon Roth (born Ulrich Roth, 18 December 1954) is a German
guitarist, who became famous as the Scorpions lead guitarist, and is one of the earliest contributors to the neoclassical metal genre.

He is the older brother of fellow guitarist and artist Zeno Roth., Neoclassical metal is a subgenre of heavy metal that is heavily influenced by classical music and usually features very technical playing, consisting of elements borrowed from both classical and speed metal music. Deep Purple's Ritchie Blackmore pioneered the subgenre by merging classical melodies and blues rock. Later, Yngwie Malmsteen became one of the most notable musicians in the subgenre, and contributed greatly to the development of the style in the 1980s. Other notable players in the genre are Randy Rhoads, Jason Becker, Tony MacAlpine, Vinnie Moore, Uli Jon Roth, Stéphan Forté and Timo Tolkki., Paavo Lötjönen (born 29 July 1968) is a cello player for Finnish band Apocalyptica.

Sweden consequently has a low population density of , with the highest concentration in the southern half of the country. Approximately 85% of the population lives in urban areas., Classical music is art music produced or rooted in the traditions of Western music, including both liturgical (religious) and secular music. While a more accurate term is also used to refer to the period from 1750 to 1820 (the Classical period), this article is about the broad span of time from roughly the 11th century to the present day, which includes the Classical period and various other periods. The central norms of this tradition became codified between 1550 and 1900, which is known as the common-practice period. The major time divisions of Western art music are as follows: 
European art music is largely distinguished from many other non-European and some popular musical forms by its system of staff notation, in use since about the 16th century. Western staff notation is used by composers to indicate to the performer the pitches (e.g., melodies, basslines, chords), tempo, meter and rhythms for a piece of music. This can leave less room for practices such as improvisation and "ad libitum" ornamentation, which are frequently heard in non-European art music and in popular-music styles such as jazz and blues. Another difference is that whereas most popular styles adopt the song (strophic) form, classical music has been noted for its development of highly sophisticated forms of instrumental music such as the concerto, symphony, sonata, and mixed vocal and instrumental styles such as opera which, since they are written down, can sustain larger forms and attain a high level of complexity., Ronald "Ron" McGovney (born November 2, 1962) is a semi-retired American musician, best known as the original bass guitarist in the heavy metal band Metallica from October 1981 to December 1982., Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia.

Input: Consider Input: 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
