Context: The Ginglymostomatidae are a cosmopolitan family of carpet sharks , containing two monotypic genera of nurse sharks . Common in shallow , tropical and subtropical waters , these sharks are sluggish and docile bottom - dwellers . Nurse sharks typically attack humans only if directly threatened . The name nurse shark is thought to be a corruption of nusse , a name which once referred to the catsharks of the family Scyliorhinidae . The nurse shark family name , Ginglymostomatidae , derives from the Greek words ginglymos (  ) meaning `` hinge '' and stoma (  ) meaning `` mouth '' ., In cryptography, SHARK is a block cipher identified as one of the predecessors of Rijndael (the Advanced Encryption Standard)., The nurse shark ("Ginglymostoma cirratum") is a shark in the family Ginglymostomatidae. Nurse sharks can reach a length of , and are native to warmer parts of the Atlantic and East Pacific., Carpet sharks are sharks classified in the order Orectolobiformes. Sometimes the common name "carpet shark" (named so because many species resemble ornately patterned carpets) is used interchangeably with "wobbegong", which is the common name of sharks in the family Orectolobidae. Carpet sharks have five gill slits, two spineless dorsal fins, and a small mouth that does not extend past the eyes. Many species have barbels., Subject: ginglymostomatidae, Relation: parent_taxon, Options: (A) ginglymostomatidae (B) orectolobiformes (C) shark

Context: A mediterranean climate or dry summer climate is the climate typical of the lands in the Mediterranean Basin. The lands around the Mediterranean Sea form the largest area where this climate type is found, but it also is found in most of coastal California, in parts of Western and South Australia, in southwestern South Africa, sections of Central Asia, and in central Chile., Salmonidae is a family of ray-finned fish, the only living family currently placed in the order Salmoniformes. It includes salmon, trout, chars, freshwater whitefishes, and graylings, which collectively are known as the salmonids. The Atlantic salmon and trout of the genus "Salmo" give the family and order their names., Croats are a nation and South Slavic ethnic group at the crossroads of Central Europe, Southeast Europe, and the Mediterranean Sea. Croats mainly live in Croatia and Bosnia and Herzegovina, but are an officially recognized minority in Austria, Czech Republic, Hungary, Italy, Montenegro, Romania, Serbia, and Slovakia. Responding to political, social and economic pressure, many Croats have migrated throughout Europe (especially Germany, Austria, Switzerland, France and Italy) and the Americas (particularly the United States, Canada, Argentina, and Chile), establishing a diaspora., The Adige is a river with its source in the Alpine province of South Tyrol near the Italian border with Austria and Switzerland. At in length, it is the second longest river in Italy, after the Po river at ., A boot is a type of footwear and a specific type of shoe. Most boots mainly cover the foot and the ankle, while some also cover some part of the lower calf. Some boots extend up the leg, sometimes as far as the knee or even the hip. Most boots have a heel that is clearly distinguishable from the rest of the sole, even if the two are made of one piece. Traditionally made of leather or rubber, modern boots are made from a variety of materials. Boots are worn both for their functionality  protecting the foot and leg from water, extreme cold, mud or hazards (e.g., work boots may protect wearers from chemicals or use a steel toe) or providing additional ankle support for strenuous activities with added traction requirements (e.g., hiking)  and for reasons of style and fashion., The North Atlantic Treaty Organization (NATO  '), also called the North Atlantic Alliance, is an intergovernmental military alliance based on the North Atlantic Treaty which was signed on 4 April 1949. The organization constitutes a system of collective defence whereby its member states agree to mutual defence in response to an attack by any external party. Three NATO members are permanent members of the United Nations Security Council with the power to veto and are officially nuclear-weapon states: the United States, France and the United Kingdom. NATO's headquarters are located in Haren, Brussels, Belgium, where the Supreme Allied Commander also resides. Belgium is one of the 28 member states across North America and Europe, the newest of which, Albania and Croatia, joined in April 2009. An additional 22 countries participate in NATO's Partnership for Peace program, with 15 other countries involved in institutionalized dialogue programmes. The combined military spending of all NATO members constitutes over 70% of the global total. Members' defence spending is supposed to amount to 2% of GDP., Fresh water is naturally occurring water on Earth's surface in ice sheets, ice caps, glaciers, icebergs, bogs, ponds, lakes, rivers and streams, and underground as groundwater in aquifers and underground streams. Fresh water is generally characterized by having low concentrations of dissolved salts and other total dissolved solids. The term specifically excludes seawater and brackish water although it does include mineral-rich waters such as chalybeate springs. The term "sweet water" (from Spanish "agua dulce") has been used to describe fresh water in contrast to salt water. The term fresh water does not have the same meaning as potable water. Much of the surface fresh water and ground water is unsuitable for drinking without some form of purification because of the presence of chemical or biological contaminants., The freshwater whitefish are fishes of the subfamily Coregoninae, which contains whitefishes (both freshwater and anadromous) and ciscoes, and is one of three subfamilies in the salmon family Salmonidae. Apart from the subfamily Coregoninae, the family Salmonidae includes the salmon, trout, and char species of the subfamily Salmoninae, and grayling species of the subfamily Thymallinae. Freshwater whitefish are distributed mainly in relatively cool waters throughout the northern parts of the Northern Hemisphere., A nation state is a type of state that joins the political entity of a state to the cultural entity of a nation, from which it aims to derive its political legitimacy to rule and potentially its status as a sovereign state.
A state is specifically a political and geopolitical entity, whilst a nation is a cultural and ethnic one. The term "nation state" implies that the two coincide, in that a state has chosen to adopt and endorse a specific cultural group as associated with it., Croatia, officially the Republic of Croatia, is a sovereign state between Central Europe, Southeast Europe, and the Mediterranean. Its capital city is Zagreb, which forms one of the country's primary subdivisions, along with its twenty counties. Croatia covers and has diverse, mostly continental and Mediterranean climates. Croatia's Adriatic Sea coast contains more than a thousand islands. The country's population is 4.28 million, most of whom are Croats, with the most common religious denomination being Roman Catholicism., Bosnia and Herzegovina (or ; B&H; Bosnian, Croatian, Serbian: "Bosna i Hercegovina" / a   ), sometimes called Bosnia-Herzegovina (BiH), and, in short, often known informally as Bosnia, is a country in Southeastern Europe located on the Balkan Peninsula. Sarajevo is the capital and largest city. Bordered by Croatia to the north, west, and south; Serbia to the east; Montenegro to the southeast; and the Adriatic Sea to the south, with a coastline about long surrounding the city of Neum. In the central and eastern interior of the country the geography is mountainous, in the northwest it is moderately hilly, and the northeast is predominantly flatland. The inland is a geographically larger region and has a moderate continental climate, with hot summers and cold and snowy winters. The southern tip of the country has a Mediterranean climate and plain topography., Salmo is a genus of fish in the salmon family Salmonidae that includes the European species of salmon and trout, among them the familiar Atlantic salmon "Salmo salar" and the brown trout "Salmo trutta". The natural distribution of "Salmo" also extends to Northern Africa and to Western Asia around the Black Sea basin. The single "Salmo" species naturally found in the Atlantic North America is the Atlantic salmon, whereas the salmon and trout of the Pacific basin belong to another genus, "Oncorhynchus". The generic name "Salmo" derives from the Latin "salm" (salmon). The number of distinct species and subspecies in "Salmo" is a debated issue. Atlantic salmon and brown trout are widespread species, while most of the other taxa are narrowly distributed forms endemic to single watersheds., The Tagliamento is a braided river in north-east Italy, flowing from the Alps to the Adriatic Sea at a point between Trieste and Venice. The source is in the Mauria Pass, on the border between the regions of Veneto and Friuli-Venezia Giulia. In the upper section, it flows through the historic Carnia region, in the northern part of the province of Udine. In the middle and lower sections, it first sets the boundary between the provinces of Udine and Pordenone and later between the former and the Province of Venice. Finally, it flows into the Gulf of Venice between Lignano Sabbiadoro and Bibione., Slovenia, officially the Republic of Slovenia (Slovene: , abbr.: "RS"), is a nation state in southern Central Europe, located at the crossroads of main European cultural and trade routes. It is bordered by Italy to the west, Austria to the north, Hungary to the northeast, Croatia to the south and southeast, and the Adriatic Sea to the southwest. It covers and has a population of 2.06 million. It is a parliamentary republic and a member of the United Nations, European Union, and NATO. The capital and largest city is Ljubljana., An ocean (the sea of classical antiquity) is a body of saline water that composes much of a planet's hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans. The word "sea" is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land., Salmon is the common name for several species of ray-finned fish in the family Salmonidae. Other fish in the same family include trout, char, grayling and whitefish. Salmon are native to tributaries of the North Atlantic (genus "Salmo") and Pacific Ocean (genus "Oncorhynchus"). Many species of salmon have been introduced into non-native environments such as the Great Lakes of North America and Patagonia in South America. Salmon are intensively farmed in many parts of the world., Freshwater fish are those that spend some or all of their lives in fresh water, such as rivers and lakes, with a salinity of less than 0.05%. These environments differ from marine conditions in many ways, the most obvious being the difference in levels of salinity. To survive fresh water, the fish need a range of physiological adaptations., 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., A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, "the sea" is the interconnected system of Earth's salty, oceanic watersconsidered as one global ocean or as several principal oceanic divisions. The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Although the sea has been traveled and explored since prehistory, the modern scientific study of the seaoceanographydates broadly to the British "Challenger" expedition of the 1870s. The sea is conventionally divided into up to five large oceanic sectionsincluding the International Hydrographic Organization's four named oceans (the Atlantic, Pacific, Indian, and Arctic) and the Southern Ocean; smaller, second-order sections, such as the Mediterranean, are known as "seas"., South Tyrol (German and ), also known by its alternative Italian name Alto Adige, is an autonomous province in northern Italy. It is one of the two autonomous provinces that make up the autonomous region of Trentino-Alto Adige/Südtirol. The province has an area of and a total population of 511,750 inhabitants (31.12.2011). Its capital is the city of Bolzano (German: "Bozen"; Ladin: "Balsan" or "Bulsan").
According to 2014 data based on the 2011 census, 62.3 percent of the population speaks German (Standard German in the written norm and an Austro-Bavarian dialect in the spoken form); 23.4 percent of the population speaks Italian, mainly in and around the two largest cities (Bolzano and Merano); 4.1 percent speaks Ladin, a Rhaeto-Romance language; 10.2% of the population (mainly recent immigrants) speaks another language as first language., 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., A parliamentary republic is a republic that operates under a parliamentary system of government where the executive branch (the government) derives its legitimacy from and is accountable to the legislature (the parliament). There are a number of variations of parliamentary republics. Most have a clear differentiation between the head of government and the head of state, with the head of government holding real power, much like constitutional monarchies. Some have combined the roles of head of state and head of government, much like presidential systems, but with a dependency upon parliamentary power., Venice (; ) is a city in northeastern Italy and the capital of the Veneto region. It is situated across a group of 117 small islands that are separated by canals and linked by bridges. These are located in the shallow Venetian Lagoon, an enclosed bay that lies between the mouths of the Po and the Piave Rivers. Parts of Venice are renowned for the beauty of their settings, their architecture, and artwork. The lagoon and a part of the city are listed as a World Heritage Site., A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague., 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., A stream is a body of water with a current, confined within a bed and banks. Depending on its location or certain characteristics, a stream may be referred to as a "bayou", "beck", "branch", "brook", "burn", "creek", "crick", "ghyll", "gill", "kill", "lick", "mill race", "race", "rill", "river", "rivulet", "run", "runnel", "streamage", "syke", or "wash"., The United Nations (UN) is an intergovernmental organization to promote international co-operation. A replacement for the ineffective League of Nations, the organization was established on 24 October 1945 after World War II in order to prevent another such conflict. At its founding, the UN had 51 member states; there are now 193. The headquarters of the United Nations is in Manhattan, New York City, and experiences extraterritoriality. Further main offices are situated in Geneva, Nairobi, and Vienna. The organization is financed by assessed and voluntary contributions from its member states. Its objectives include maintaining international peace and security, promoting human rights, fostering social and economic development, protecting the environment, and providing humanitarian aid in cases of famine, natural disaster, and armed conflict., Marble trout ( Salmo marmoratus ) is a species freshwater fish in the Salmonidae family . It is characterized by distinctive marbled color pattern and high growth capacity . The marble trout is found in only three basins and two rivers of the Adriatic basin , namely the Po with only northern / left tributaries and the Adige , Brenta , Piave , Tagliamento and Livenza basins in Italy , the Soa basin in Slovenia , the Neretva river in Bosnia and Herzegovina and Croatia , and the Moraa river in Montenegro . While once present in the Drin river basin in Albania fish is almost certainly extirpated there ., Trout is the common name for a number of species of freshwater fish belonging to the genera "Oncorhynchus", "Salmo" and "Salvelinus", all of the subfamily Salmoninae of the family Salmonidae. The word "trout" is also used as part of the name of some non-salmonid fish such as "Cynoscion nebulosus", the spotted seatrout or speckled trout., Subject: salmo marmoratus, Relation: taxon_rank, Options: (A) branch (B) division (C) family (D) form (E) genus (F) group (G) kingdom (H) order (I) section (J) species (K) subfamily (L) subspecies (M) variety
