Question: Context: England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight., Hornby Dock was a dock located on the River Mersey, England, and part of the Port of Liverpool. It was situated in the northern dock system in Bootle. It connected to Gladstone Dock to the north and Alexandra Dock to the south and encompassed a sloping quayside. , The City and South London Railway (C&SLR) was the first deep-level underground "tube" railway in the world, and the first major railway to use electric traction. The railway was originally intended for cable-hauled trains, but owing to the bankruptcy of the cable contractor during construction, a system of electric traction using electric locomotivesan experimental technology at the timewas chosen instead., The Mersey Docks and Harbour Company (MDHC), formerly the Mersey Docks and Harbour Board (MDHB), owns and administers the dock facilities of the Port of Liverpool, on the River Mersey, England. These include the operation of the enclosed northern dock system that runs from Prince's Dock to Seaforth Dock, in the city of Liverpool and the dock facilities built around the Great Float of the Wirral Peninsula, located on the west side of the river., The Liverpool Overhead Railway (known locally as the Dockers' Umbrella) was an overhead railway in Liverpool which operated along the Liverpool Docks and opened in 1893 with lightweight electric multiple units. The railway had a number world firsts; it was the first electric elevated railway, the first to use automatic signalling & electric colour light signals, electric multiple units, and was home to one of the first passenger escalator at a railway station. It was also the second oldest electric metro in the world being preceded by the 1890 City and South London Railway. In the early 1900s electric trains ran on the electrified Lancashire and Yorkshire Railway to Southport and Aintree. Special trains to Aintree for the horse race meetings ran twice a year after regular services were withdrawn. Being a local railway it was not nationalised in 1948., Liverpool, in North West England, is a major city and metropolitan borough with an estimated population of 478,580 in 2015 within the City of Liverpool. Liverpool and its surrounding areas form the fifth largest metropolitan area in the UK, with an estimated population of over 2.24 million in 2011. The local authority is Liverpool City Council, which is the most populous local government district within the metropolitan county of Merseyside and the largest within the Liverpool City Region., The River Mersey is a river in the north west of England. Its name is derived from the Anglo-Saxon language and translates as "boundary river". The river may have been the border between the ancient kingdoms of Mercia and Northumbria and for centuries it formed part of the boundary between the historic counties of Lancashire and Cheshire., Gladstone Dock is a dock on the River Mersey, England, and part of the Port of Liverpool. It is situated in the northern dock system in Bootle. The dock is connected to Seaforth Dock to the north and what remains of Hornby Dock to the south. Part of Liverpool Freeport, Gladstone Dock is operated by the Mersey Docks and Harbour Company., The Lancashire and Yorkshire Railway (L&YR) was a major British railway company before the 1923 Grouping. It was incorporated in 1847 from an amalgamation of several existing railways. It was the third-largest railway system based in Northern England (after the Midland and North Eastern Railways)., The Port of Liverpool is the enclosed dock system that runs from Brunswick Dock in Liverpool to Seaforth Dock, Seaforth, on the east side of the River Mersey and the Birkenhead Docks between Birkenhead and Wallasey on the west side of the river. The port is being extended by the building of an in-river container terminal at Seaforth Dock, name Liverpool2. The terminal will berth two 14,000 container Post-Panamax ships. The terminal was scheduled to be opened in phases during 2016, simultaneously with the widened third locks of the Panama Canal., Seaforth Dock (also known as the Royal Seaforth Dock) is a purpose-built dock and container terminal, on the River Mersey, England, at Seaforth, to the north of Liverpool. As part of the Port of Liverpool and Liverpool Freeport, it is operated by the Mersey Docks and Harbour Company. Situated at the northern end of the dock system, it is connected to Gladstone Dock to the south, which via its lock entrance provides maritime access to Seaforth Dock from the river.
History.
Despite planning permission having been obtained almost sixty years previously, work commenced during the 1960s on Liverpool's largest dock facility. The dock was the largest built in the United Kingdom for some time, with of quay and a depth of and world's largest lock gates., Bootle (pronounced ) is a town within the Metropolitan Borough of Sefton in Merseyside. The town was formerly known as Bootle-cum-Linacre and has a total resident population of 77,640., Gladstone Dock was a station on the Liverpool Overhead Railway , between Alexandra Dock and Seaforth Sands . It was opened on 16 June 1930 , the final station to open on the network . It was named after the adjacent Gladstone Dock , and was the only station on the network to be accessible directly from the dockside , with two steel bridges connecting the platforms , as it primarily served the passenger liners which frequently docked nearby . Only the northbound platform was directly accessible from the street . The station was opened at 6am on the first day of operation without a formal ceremony . It was originally only open on week days , but service was intended to be extended to be extended to weekends . The station was damaged during the Liverpool Blitz , requiring it to be rebuilt . The station closed , along with the rest of the line on 30 December 1956 .

Question: Context: The Mediterranean Sea (pronounced ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The sea is sometimes considered a part of the Atlantic Ocean, although it is usually identified as a separate body of water., Gargano is a historical and geographical sub-region in the province of Foggia, Apulia, southeast Italy, consisting of a wide isolated mountain massif made of highland and several peaks and forming the backbone of the Gargano Promontory projecting into the Adriatic Sea, the "spur" on the Italian "boot". The high point is Monte Calvo at . Most of the upland area, about , is part of the Gargano National Park, founded in 1991. It is within the Italian Province of Foggia., The Calabrian dialect of Greek, or Greek-Bovesian, is the variety of Italiot Greek used by the ethnic Griko people in Calabria, as opposed to the Italiot Greek dialect spoken in the Grecìa Salentina. Both are remnants of the Ancient and Byzantine Greek colonization of the region. They are frequently lumped together as "Italiot Greek" (Katoitaliótika), Grecanic or Griko, but they have different histories., Gaeta (Ancient Greek: ) is a city and "comune" in the province of Latina, in Lazio, central Italy. Set on a promontory stretching towards the Gulf of Gaeta, it is from Rome and from Naples., Southern Italy or Mezzogiorno (literally "midday") is the traditional term for the southern regions of Italy, encompassing the southern section of the continental Italian Peninsula, the island of Sicily, and usually the island of Sardinia. It generally coincides with the administrative regions of Abruzzo, Apulia, Basilicata, Campania, Calabria, Molise, Sicily, and Sardinia. Some also include the most southern and eastern parts of Lazio (Sora, Cassino, Gaeta, Cittaducale and Amatrice districts) within the "Mezzogiorno", because these territories were also part of the Kingdom of the Two Sicilies. The island of Sardinia, although for cultural and historical reasons having less in common with the aforementioned regions, is frequently included as Southern Italy or "Mezzogiorno", often for statistical and economical purposes., Salento (Salentu in the Salentino dialect) is a geographic region at the southern end of the administrative region of Apulia in Southern Italy. It is a sub-peninsula of the Italian Peninsula, sometimes described as the "heel" of the Italian "boot"., The Kingdom of the Two Sicilies was the largest of the states of Italy before the Italian unification. It was formed as a union of the Kingdom of Sicily and the Kingdom of Naples, which collectively had long been called the "Two Sicilies" ("Utraque Sicilia", literally "both Sicilies")., Abruzzo is a region of Italy in Southern Italy, with an area of 10,763 square km (4,156 sq mi) and a population of 1.3 million. Its western border lies east of Rome. The region is divided into the four provinces of L'Aquila, Teramo, Pescara, and Chieti. Abruzzo borders the region of Marche to the north, Lazio to the west and south-west, Molise to the south-east, and the Adriatic Sea to the east. Geographically, Abruzzo is divided into a mountainous area to the west, which includes the Gran Sasso D'italia, and a coastal area to the east with beaches on the Adriatic sea. Abruzzo is considered culturally, linguistically, and historically a region of Southern Italy, although geographically it may also be considered central. The Italian Statistical Authority (ISTAT) deems it to be part of Southern Italy, partially because of Abruzzo's historic association with the Kingdom of the Two Sicilies., Southern Europe is the southern region of the European continent. Most definitions of Southern Europe, also known as Mediterranean Europe, include the countries of the Iberian peninsula (Spain and Portugal), the Italian peninsula, Southern France, Greece and Malta. Other definitions sometimes include the Balkan countries of Southeast Europe, which are geographically technically in the southern part of Europe, but which have different historical, political, economic, and cultural backgrounds that commonly places them in the category of Eastern Europe., Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino and Vatican City. Italy covers an area of and has a largely temperate seasonal climate and Mediterranean climate; due to its shape, it is often referred to in Italy as "lo Stivale" (the Boot). With 61 million inhabitants, it is the fourth most populous EU member state., Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries., Campania is a region in Southern Italy. The region at the end of 2014 had a population of around 5,869,000 people, making it the third-most-populous region of Italy; its total area of makes it the most densely populated region in the country. Located on the Italian Peninsula, with the Mediterranean Sea to the west, it includes the small Phlegraean Islands and Capri for administration as part of the region., Amatrice is a town and "comune" in the province of Rieti, in northern Lazio (central Italy), and the center of the food-agricultural area of Gran Sasso e Monti della Laga National Park. The town was devastated by a powerful earthquake on 24 August 2016., The Italian Peninsula or Apennine Peninsula ("Penisola appenninica") is the central and the smallest of the three large peninsulas of Southern Europe (between the Iberian Peninsula and the Balkan Peninsula). It extends from the Po Valley in the north to the central Mediterranean Sea in the south. The peninsula's shape gives it the nickname "lo Stivale" (the Boot). Three smaller peninsulas contribute to this characteristic shape, namely Calabria (the "toe"), Salento (the "heel") and Gargano (the "spur")., Lazio (; ) is one of the 20 administrative regions of Italy, situated in the central peninsular section of the country. With almost 5.9 million residents and a GDP of more than 170 billion euros, Lazio is the second most populated region of Italy (having approximately the same in population as Campania), and has the second largest economy of the nation. Its capital is Rome, capital and largest city of Italy., Apulia ( Apoulia) is a region of Italy in Southern Italy bordering the Adriatic Sea in the east, the Ionian Sea to the southeast, and the Strait of Òtranto and Gulf of Taranto in the south. Its southernmost portion, known as the Salento peninsula, forms a "stiletto" on the "boot" of Italy. The region comprises , and its population is about 4 million., Basilicata (or ), also known as Lucania, is a region in the south of Italy, bordering on Campania to the west, Apulia ("Puglia") to the north and east, and Calabria to the south. It also has two coastlines, one on the Tyrrhenian Sea between Campania and Calabria, and a longer coastline along the Gulf of Taranto between Calabria and Apulia. The region can be thought of as the "instep" of Italy, with Calabria functioning as the "toe" and Apulia the "heel". The region covers about and in 2010 had a population slightly under 600,000. The regional capital is Potenza. The region is divided into two provinces: Potenza and Matera. The president of Basilicata is Marcello Pittella., Cittaducale is a "comune" (municipality) in the Province of Rieti in the Italian region Lazio, located about northeast of Rome and about southeast of Rieti. As of 31 December 2004, it had a population of 6,799 and an area of . It was once part of the Abruzzi Region., Calabria ( Italian pronunciation : ( kalabrja ) ; Calàbbria in Calabrian , Calavría in Calabrian Greek ,  in Greek , Kalavrì in Arbëresh ) , known in antiquity as Bruttium or formerly as Italia , is a region in Southern Italy , forming the `` toe '' of the Italian Peninsula . The capital city of Calabria is Catanzaro , while its most populated city and the seat of the Calabrian Regional Council is Reggio . It is bordered to the north by the region of Basilicata , to the west by the Tyrrhenian Sea , and to the east by the Ionian Sea . The region covers 15,080 km2 ( 5,822 sq mi ) and has a population of just under 2 million . The demonym of Calabria in English is Calabrian . In ancient times Calabria was referred to as `` Italy '' . The Romans later extended the name to cover Southern Italy and then the entire peninsula . Whereas the name Calabria was used to refer to the peninsula of Salento ( also known as the `` heel '' of Italy ) ., Sardinia ( / , Sassarese: "Sardhigna", Gallurese: "Saldigna", Catalan: "Sardenya", Tabarchino: "Sardegna") is the second largest island in the Mediterranean Sea (after Sicily and before Cyprus) and an autonomous region of Italy. It is located in the Western Mediterranean, just south of the French island of Corsica., Grecìa Salentina (Italian for "Salentinian Greek-speaking land") is an area in the peninsula of Salento in southern Italy, near the town of Lecce which is inhabited by the Griko people, an ethnic Greek minority in southern Italy who speak Griko, a variant of Greek., The Iberian Peninsula , also known as Iberia , is located in the southwest corner of Europe. The peninsula is principally divided between Portugal and Spain, comprising most of their territory. It also includes Andorra and a small part of France along the peninsula's northeastern edge, as well as Gibraltar on its south coast, a small peninsula which forms an overseas territory of the United Kingdom. With an area of approximately , it is the second largest European peninsula, after the Scandinavian., Sicily is the largest island in the Mediterranean Sea. It constitutes an autonomous Region of Italy, along with surrounding minor islands, officially referred to as "Regione Siciliana" (in Italian, Sicilian Region)., The Po Valley, Po Plain, Plain of the Po, or Padan Plain (, "Val Padana or Padania") is a major geographical feature of Italy. It extends approximately in an east-west direction, with an area of including its Venetic extension not actually related to the Po river basin; it runs from the Western Alps to the Adriatic Sea. The flatlands of Veneto and Friuli are often considered apart since they do not drain into the Po, but they effectively combine into an unbroken plain., Cassino is a "comune" in the province of Frosinone, Italy, at the southern end of the region of Lazio., Molise is a region of Southern Italy. Until 1963, it formed part of the region of "Abruzzi e Molise", alongside the region of Abruzzo. The split, which did not become effective until 1970, makes Molise the youngest region in Italy. The region covers (the Aosta Valley is the only smaller region) and has a population of 313,348 (as of 1 January 2015), Subject: calabria, Relation: instance_of, Options: (A) administration (B) administrative region (C) area (D) association (E) august (F) body of water (G) border (H) city (I) comune (J) concept (K) continent (L) december (M) dialect (N) extension (O) geographic region (P) geographical (Q) highland (R) island (S) italy (T) january (U) massif (V) may (W) mediterranean sea (X) municipality (Y) nation (Z) ocean ([) overseas territory (\) part (]) peninsula (^) people (_) point (`) population (a) portugal (b) promontory (c) province (d) region (e) region of italy (f) republic (g) river (h) sea (i) term (j) territory (k) three (l) town (m) two (n) union (o) valley

Answer: region of italy


Question: Context: Amphibians are ectothermic, tetrapod vertebrates of the class Amphibia. Modern amphibians are all Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline in amphibian populations for many species around the globe., Birds (Aves), also known as avian dinosaurs, are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. They rank as the class of tetrapods with the most living species, at approximately ten thousand, with more than half of these being passerines, sometimes known as perching birds or, less accurately, as songbirds., A vivarium (Latin, literally for "place of life"; plural: "vivaria" or "vivariums") is an area, usually enclosed, for keeping and raising animals or plants for observation or research. Often, a portion of the ecosystem for a particular species is simulated on a smaller scale, with controls for environmental conditions., A fin is a thin component or appendage attached to a larger body or structure. Fins typically function as foils that produce lift or thrust, or provide the ability to steer or stabilize motion while traveling in water, air, or other fluid media. Fins are also used to increase surface areas for heat transfer purposes, or simply as ornamentation., Hagfish, the class Myxini (also known as Hyperotreti), are eel-shaped, slime-producing marine fish (occasionally called slime eels). They are the only known living animals that have a skull but no vertebral column. Along with lampreys, hagfish are jawless; they are the sister group to vertebrates, and living hagfish remain similar to hagfish from around 300 million years ago., 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., Invertebrates are animals that neither possess nor develop a vertebral column (commonly known as a "backbone" or "spine"), derived from the notochord. This includes all animals apart from the subphylum Vertebrata. Familiar examples of invertebrates include insects; crabs, lobsters and their kin; snails, clams, octopuses and their kin; starfish, sea-urchins and their kin; and worms., A craniate is a member of Craniata (sometimes Craniota), a proposed clade of chordate animals that contains the Myxini (hagfish), Petromyzontida (including lampreys), and the much more numerous Gnathostomata (jawed vertebrates) as living representatives. As the name suggests, craniates are animals with a (hard bone or cartilage) skull in phylum Chordata., Lampreys (sometimes also called, inaccurately, lamprey eels) are any jawless fish of the order Petromyzontiformes, placed in the superclass Cyclostomata. The adult lamprey may be characterized by a toothed, funnel-like sucking mouth. The common name "lamprey" is probably derived from Latin "lampetra", which may mean "stone licker" ("lambere" "to lick" + "petra" "stone"), though the etymology is uncertain., A public aquarium (plural: "public aquaria" or " public aquariums") is the aquatic counterpart of a zoo, which houses living aquatic animal and plant specimens for public viewing. Most public aquariums feature tanks larger than those kept by home aquarists, as well as smaller tanks. Since the first public aquariums were built in the mid-19th century, they have become popular and their numbers have increased. Most modern accredited aquariums stress conservation issues and educating the public., An aquarium (plural: "aquariums" or "aquaria") is a vivarium of any size having at least one transparent side in which water-dwelling plants or animals are kept and displayed. Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles such as turtles, and aquatic plants. The term, coined by English naturalist Philip Henry Gosse, combines the Latin root "aqua", meaning water, with the suffix "-arium", meaning "a place for relating to". The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as their numbers do not grow too large. The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, "The Aquarium: An Unveiling of the Wonders of the Deep Sea" in 1854., A gill is a respiratory organ found in many aquatic organisms that extracts dissolved oxygen from water and excretes carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment., Nannostomus (from the Greek: "nanno" = small, "stomus" = mouth) is a genus of fish belonging to the Lebiasinidae family of characins. All of the species in this genus are known as pencil fish or pencilfish, a popular name that was first only applied to two species in the 1920s, "Nannostomus unifasciatus" and "Nannostomus eques", but by the late 1950s would come to be applied to all members of the genus. Several of the species have become popular aquarium fish due to their attractive coloration, unique shape, and interesting demeanor., The pencil fishes are a family (Lebiasinidae) of freshwater fishes found in Costa Rica, Panama, and South America. They are usually small and are known as ornamental fishes in aquaria, including popular fishes such as the various pencil fish and the splashing tetra., Sexual reproduction is a form of reproduction where two morphologically distinct types of specialized reproductive cells called gametes fuse together, involving a female's large ovum (or egg) and a male's smaller sperm. Each gamete contains half the number of chromosomes of normal cells. They are created by a specialized type of cell division, which only occurs in eukaryotic cells, known as meiosis. The two gametes fuse during fertilization to produce DNA replication and the creation of a single-celled zygote which includes genetic material from both gametes. In a process called genetic recombination, genetic material (DNA) joins up so that homologous chromosome sequences are aligned with each other, and this is followed by exchange of genetic information. Two rounds of cell division then produce four daughter cells with half the number of chromosomes from each original parent cell, and the same number of chromosomes as both parents, though self-fertilization can occur. For instance, in human reproduction each human cell contains 46 chromosomes, 23 pairs, except gamete cells, which only contain 23 chromosomes, so the child will have 23 chromosomes from each parent genetically recombined into 23 pairs. Cell division initiates the development of a new individual organism in multicellular organisms, including animals and plants, for the vast majority of whom this is the primary method of reproduction., A tunicate is a marine invertebrate animal, a member of the subphylum Tunicata, which is part of the Chordata, a phylum which includes all animals with dorsal nerve cords and notochords. The subphylum was at one time called Urochordata, and the term urochordates is still sometimes used for these animals. Some tunicates live as solitary individuals, but others replicate by budding and become colonies, each unit being known as a zooid. They are marine filter feeders with a water-filled, sac-like body structure and two tubular openings, known as siphons, through which they draw in and expel water. During their respiration and feeding, they take in water through the incurrent (or inhalant) siphon and expel the filtered water through the excurrent (or exhalant) siphon. Most adult tunicates are sessile, and are permanently attached to rocks or other hard surfaces on the ocean floor; others, such as salps, doliolids and pyrosomes, swim in the pelagic zone of the sea as adults. Various species are commonly known as sea squirts, sea pork, sea livers, or sea tulips., Deoxyribonucleic acid (DNA) is a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses. DNA and RNA are nucleic acids; alongside proteins, lipids and complex carbohydrates (polysaccharides), they are one of the four major types of macromolecules that are essential for all known forms of life. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix., Panama, officially called the Republic of Panama, is a country usually considered to be entirely in North America or Central America. It is bordered by Costa Rica to the west, Colombia (in South America) to the southeast, the Caribbean Sea to the north and the Pacific Ocean to the south. The capital and largest city is Panama City, whose metropolitan area is home to nearly half of the country's 3.9 million people., Mammals are any vertebrates within the class Mammalia (from Latin "mamma" "breast"), a clade of endothermic amniotes distinguished from reptiles and birds by the possession of a neocortex (a region of the brain), hair, three middle ear bones and mammary glands. The sister group of mammals may be the extinct "Haldanodon." The mammals represent the only living Synapsida, which together with the Sauropsida form the Amniota clade. The mammals consist of the Yinotheria including monotrema and the Theriiformes including the theria., Nannostomus trifasciatus , commonly known as the three - lined or three - stripepencilfish , is a freshwater species of fish belonging to the Lebiasinidae family of characins . They are popular in the aquarium trade due to their small size , beautiful color pattern , and relative hardiness ., 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., In biology, a species (abbreviated sp., with the plural form species abbreviated spp.) is the basic unit of biological classification and a taxonomic rank. A species is often defined as the largest group of organisms in which two individuals can produce fertile offspring, typically by sexual reproduction. While this definition is often adequate, looked at more closely it is often problematic. For example, in a species complex, the boundaries between closely related species become unclear or disappear altogether. Other ways of defining species include similarity of DNA, morphology, or ecological niche. The presence of locally adaptive traits may further subdivide species into infraspecific taxa such as subspecies., The superclass Tetrapoda (Ancient Greek s tetrapods, "four-footed"), or the tetrapods , comprises the first four-limbed vertebrates and their descendants, including the living and extinct amphibians, birds, mammals, reptiles and some ancient, exclusively aquatic creatures such as the Acanthostega. Tetrapods evolved from the lobe-finned fishes around 390 million years ago in the middle Devonian Period, with modern tetrapod groups having appeared by the late Devonian, 367.5 million years ago. The specific aquatic ancestors of the tetrapods, and the process by which land colonization occurred, remain unclear, and are areas of active research and debate among palaeontologists at present., Reptiles are tetrapod (four-limbed vertebrate) animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders, historically combined with that of modern amphibians, is called herpetology., Costa Rica (literally meaning "Rich Coast"), officially the Republic of Costa Rica, is a country in Central America, bordered by Nicaragua to the north, Panama to the southeast, the Pacific Ocean to the west, the Caribbean Sea to the east, and Ecuador to the south of Cocos Island. It has a population of around 4.5 million, of whom nearly a quarter live in the metropolitan area of the capital and largest city, San José., Subject: nannostomus trifasciatus, Relation: parent_taxon, Options: (A) amphibia (B) animal (C) area (D) areas (E) chordata (F) cocos (G) craniata (H) hagfish (I) helix (J) hermit (K) human (L) insects (M) lampetra (N) lebiasinidae (O) lissamphibia (P) olfactores (Q) ostrich (R) pencil fish (S) petromyzontiformes (T) plant (U) reptile (V) sauropsida (W) tetrapoda (X) theria (Y) tunicate (Z) vertebrata
