Context: George Dilboy ( Americanized transliteration of Greek name :   ) , ( February 5 , 1896 -- July 18 , 1918 ) , Private First Class , U.S. Army , Company H , 103d Infantry , 26th Division is thought to be the first Greek - American to receive the Medal of Honor during World War I. He led an attack on a machine gun position and continued to fire at the enemy despite being seriously wounded , killing two of the enemy and dispersing the remainder of the gun crew . General John Pershing listed George Dilboy as `` one of the ten great heroes '' who `` died in the battlefield of France with super-human heroism and valor . '' Dilboy is buried in Section 18 of Arlington National Cemetery ., Arlington National Cemetery is a United States military cemetery in Arlington County, Virginia, across the Potomac River from Washington, D.C., in whose the dead of the nation's conflicts have been buried, beginning with the American Civil War, as well as reinterred dead from earlier wars. The United States Department of the Army, a component of the United States Department of Defense, controls the cemetery., A battle rifle is a military service rifle that fires a full-power rifle cartridge, such as 7.62×51mm NATO, 7.62×54mmR, 7.92x57mm Mauser, .303 British, or .30-06 Springfield. Compared to assault rifles and their intermediate cartridges, the higher-caliber rounds provide greater power and range, though they have greater weight and produce stronger recoil, making them less than ideal for fully automatic fire., Military personnel are members of the armed forces. Usually, personnel are divided into military branches roughly defined by certain circumstances of their deployment. Those who serve in a typical large land force are soldiers, making up an army. Those who serve in seagoing forces are seamen or sailors, and their branch is a navy or coast guard . Marines serve in a marine corps. In the 20th century, the development of powered flight aircraft prompted the development of air forces, serviced by airmen. Designated leaders of military personnel are officers. These include commissioned officers, warrant officers and non-commissioned officers (NCOs). For naval forces, non-commissioned officers are referred to as petty officers (POs).
military personnel are instructed to wear dog tags, Genocide is intentional action to destroy a people (usually defined as an ethnic, national, racial, or religious group) in whole or in part. The hybrid word "genocide" is a combination of the Greek word "génos" ("race, people") and the Latin suffix "-cide" ("act of killing"). The United Nations Genocide Convention defines genocide as "acts committed with intent to destroy, in whole or in part, a national, ethnic, racial or religious group"., The Department of the Army (DA) is one of the three military departments within the Department of Defense of the United States of America. The Department of the Army is the Federal Government agency within which the United States Army is organized, and it is led by the Secretary of the Army who has statutory authority to conduct its affairs and to prescribe regulations for its government, subject to the limits of the law, and the directions of the Secretary of Defense and the President., A machine gun is a fully automatic mounted or portable firearm, designed to fire bullets in quick succession from an ammunition belt or magazine, typically at a rate of 300 to 1800 rounds per minute. Fully automatic firearms are generally categorized as submachine guns, assault rifles, battle rifles, automatic shotguns, machine guns, or autocannons. Machine guns with multiple rotating barrels are referred to as "rotary machine guns"., The term cult usually refers to a social group defined by their religious, spiritual, or philosophical beliefs, or common interest in a particular personality, object or goal. The term itself is controversial and has divergent definitions in popular culture and in academia and has been an ongoing source of contention among scholars across several fields of study. In the sociological classifications of religious movements, a cult is a social group with socially deviant or novel beliefs and practices, although this is often unclear. Other researchers present a less-organized picture of cults on the basis that cults arise spontaneously around novel beliefs and practices. The word "cult" has always been controversial because it is (in a pejorative sense) considered a subjective term, used as an "ad hominem" attack against groups with differing doctrines or practices. Cults range in size from local groups with a few members to international organizations with millions., In general, a civilian is "a person who is not a member of the military or of a police or firefighting force", as defined by Merriam Webster's Dictionary. From the perspective of the U.S. Department of Defense, Chapter 18 of Title 10 United States Code refers to non-military law enforcement officers as civilians since they are employees rather than enlisted personnel, and also in order to distinguish itself from military police. In military and law enforcement slang, the term "Civies" or "Civvies" are often used to refer civilian population or civilian clothing., An autocannon or automatic cannon is a large, fully automatic, rapid-fire projectile weapon that fires armour-piercing or explosive shells, as opposed to the bullet fired by a machine gun. Autocannons often have a larger calibre than a machine gun (e.g., 20 mm or greater), but are usually smaller than a field gun or other artillery. When used on its own, the word "autocannon" indicates a single-barrel weapon. When multiple rotating barrels are involved, the word "rotary" is added, and such a weapon is referred to as a "rotary autocannon." Modern autocannons are typically not single soldier-portable or stand-alone units, rather they are usually vehicle-mounted, aircraft-mounted, or boat-mounted, or even remote-operated as in some naval applications. As such, ammunition is typically fed from a belt to reduce reloading or for a faster rate of fire, but a magazine remains an option. They can use a variety of ammunition: common shells include high-explosive dual-purpose types (HEDP), any variety of armour-piercing (AP) types, such as composite rigid (APCR) or discarding sabot types (APDS)., France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux., A submachine gun (SMG) is an air-cooled, magazine-fed, automatic carbine designed to fire pistol cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun., World War I (WWI or WW1), also known as the First World War, or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare. It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved., The euro (sign: €; code: EUR) is the official currency of the eurozone, which consists of 19 of the member states of the European Union: Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain. The currency is also officially used by the institutions of the European Union and four other European countries, as well as unilaterally by two others, and is consequently used daily by some 337 million Europeans . Outside of Europe, a number of overseas territories of EU members also use the euro as their currency., The word bullet is a firearm term. A bullet is a projectile expelled from the barrel of a firearm. The term is from Middle French and originated as the diminutive of the word boulle (boullet) which means "small ball." Bullets are made of a variety of materials. They are available singly as they would be used in muzzle loading and cap and ball firearms, as part of a paper cartridge, and much more commonly as a component of metallic cartridges. Bullets are made in a large numbers of styles and constructions depending on how they will be used. Many bullets have specialized functions, such as hunting, target shooting, training, defense, and warfare. , A republic (from ) is a sovereign state, country, or government which is organized with a form of government in which power resides in elected individuals representing the citizen body and government leaders exercise power according to the rule of law. In modern times, the definition of a republic commonly refers to a government which excludes a monarch. Currently, 147 of the world's 206 sovereign states use the word "republic" as part of their official names; not all of these are republics in the sense of having elected governments, nor do all nations with elected governments use the word "republic" in their names., Subject: george dilboy, Relation: occupation, Options: (A) army (B) coast guard (C) commercial (D) general (E) hunting (F) inventor (G) law enforcement (H) major (I) member (J) military (K) military personnel (L) monarch (M) official (N) police (O) religious (P) soldier (Q) sovereign (R) united states of america

Context: The British Railways Board (BRB) was a nationalised industry in the United Kingdom that operated from 1963 to 2001. Until 1997 it was responsible for most railway services in Great Britain, trading under the brand name British Railways and, from 1965, British Rail. It did not operate railways in Northern Ireland, where railways were the responsibility of the Government of Northern Ireland., The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., Automatic train operation (ATO) is an operational safety enhancement device used to help automate operations of trains. Mainly, it is used on automated guideway transits and rapid transit systems which are easier to ensure safety of humans. Most systems elect to maintain a driver (train operator) to mitigate risks associated with failures or emergencies., Tottenham was a local government district in north east Middlesex from 1850 to 1965. It was part of the London postal district and Metropolitan Police District., The Northern line is a London Underground line, coloured black on the Tube map. The section between Stockwell and Borough opened in 1890, and is the oldest section of deep-level tube line on the network., Surrey is a county in the south east of England and also one of the home counties bordering Greater London. Surrey shares borders with Kent to the east, East Sussex to the south-east, West Sussex to the south, Hampshire to the west and south-west and Berkshire to the north-west. The county town is Guildford. Surrey County Council sits extraterritorially at Kingston upon Thames, administered as part of Greater London since 1965. With a resident population of 1.1 million, Surrey is the most densely populated and third most populated county in the South East region, after Kent and Hampshire., Middlesex (abbreviation: Middx) was a county in southeast England that is now mostly part of Greater London, with small sections in neighbouring counties. It was established in the Anglo-Saxon system from the territory of the Middle Saxons, and existed as an official unit until 1965. The historic county included land stretching north of the River Thames from east to west of the City of London with the rivers Colne and Lea and a ridge of hills as the other boundaries. The largely low-lying county, dominated by clay in its north and alluvium on gravel in its south, was the second smallest by area in 1831., Tottenham Hale is a National Rail and London Underground Victoria line station in Tottenham , north London . It is on Ferry Lane , with access from Watermead Way . The station is in Travelcard Zone 3 . The national rail gateline now has automatic barriers installed : rail users must use the Underground doors to the station . A new station building is awaiting planning approval , and a third railway platform is being worked on . This is all part of the 2013/14 Tottenham Hale regeneration scheme ., Rapid transit, also known as heavy rail, metro, subway, tube, or underground, is a type of high-capacity public transport generally found in urban areas. Unlike buses or trams, rapid transit systems are electric railways that operate on an exclusive right-of-way, which cannot be accessed by pedestrians or other vehicles of any sort, and which is often grade separated in tunnels or on elevated railways., The London Borough of Haringey 
is a London borough in North London, classified by some definitions as part of Inner London, and by others as part of Outer London. It was created in 1965 by the amalgamation of three former boroughs. It shares borders with six other London boroughs. Clockwise from the north, they are: Enfield, Waltham Forest, Hackney, Islington, Camden, and Barnet., The Rail Delivery Group (RDG), formerly Association of Train Operating Companies (ATOC), is a body that represents the 23 train operating companies that provide passenger services on the privatised British railway system. It owns the National Rail brand. RDG is an unincorporated association owned by its members. It was set up by the train operators formed during privatisation of the railways under the Railways Act 1993. Its office is in London., North London is the northern part of London, England. It is an imprecise description and the area it covers is defined differently for a range of purposes. Common to these definitions is that it includes districts north of the River Thames and is used in comparison with south London. However, it is also often used in comparisons with central London, east London and west London., The Tube map is a schematic transport map of the lines, stations and services of London's public transport systems, the primary system being London Underground, known colloquially as "the Tube", hence the map's name. The first schematic Tube map was designed by Harry Beck in 1931, and it has since been expanded to also include today the Docklands Light Railway, London Overground, TfL Rail, Tramlink and the Emirates Air Line cable car., The River Thames is a river that flows through southern England. At , it is the longest river entirely in England and the second longest in the United Kingdom, after the River Severn. It also flows through Oxford (where it is called Isis), Reading, Henley-on-Thames and Windsor. The lower reaches of the river are called the Tideway, derived from its long tidal reach up to Teddington Lock. It rises at Thames Head in Gloucestershire, and flows into the North Sea via the Thames Estuary. The Thames drains the whole of Greater London. , Buckinghamshire (or ), abbreviated Bucks, is a county in South East England which borders Greater London to the south east, Berkshire to the south, Oxfordshire to the west, Northamptonshire to the north, Bedfordshire to the north east and Hertfordshire to the east., Brixton is a district of London, located in the borough of Lambeth in south London. The area is identified in the London Plan as one of 35 major centres in Greater London., The City of London is a city and county within London. It constituted most of London from its settlement by the Romans in the 1st century AD to the Middle Ages, but the agglomeration has since grown far beyond the City's borders. The City is now only a tiny part of the metropolis of London, though it remains a notable part of central London. Administratively, it forms one of the 33 local authority districts of Greater London; however, the City of London is not a London borough, a status reserved for the other 32 districts (including London's only other city, the City of Westminster). , Charing Cross denotes the junction of Strand, Whitehall and Cockspur Street, just south of Trafalgar Square in central London. It gives its name to several landmarks, including Charing Cross railway station, one of the main London rail terminals., Kent is a county in South East England and one of the home counties. It borders Greater London to the north west, Surrey to the west, East Sussex to the south west, and Essex across the Thames Estuary to the north. The county town is Maidstone. , Tottenham is an area in the London Borough of Haringey, in north London, England. It is situated north-north-east of Charing Cross., Walthamstow (or ) is the principal town of the London Borough of Waltham Forest in East London, England. It is located northeast from Charing Cross., Her Majesty's Principal Secretary of State for Transport is the member of the cabinet responsible for the British Department for Transport. The office used to be called the Minister of Transport and has been merged with the Department for the Environment at various times., The Piccadilly line is a line of the London Underground, coloured dark blue on the Tube map. It is the fourth busiest line on the Underground network on the basis of the number of passengers transported per year with 210,000,000. It is mainly a deep-level line, running from the north to the west of London via Zone 1, with a number of surface sections, mostly in its westernmost parts. It is named after the road above it between Hyde Park Corner and Piccadilly Circus. Some of its stations are shared with the District line and some are shared with the Metropolitan line. It is the second longest line on the system, after the Central line, and has the second most stations, after the District line. It serves many of London's top tourist attractions including Harrods (Knightsbridge), Hyde Park, Buckingham Palace (within walking distance from Green Park), Piccadilly Circus, Leicester Square and Covent Garden, as well as London Heathrow Airport, the busiest airport in Europe. The line shares tracks with the Metropolitan line between Uxbridge and Rayners Lane, and with the District line between Hanger Lane Junction and Acton Town, then runs parallel with the District line between Acton Town and Barons Court., London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly., Londinium was a settlement established on the current site of the City of London around  43. Its bridge over the River Thames turned the city into a road nexus and major port, serving as a major commercial centre in Roman Britain until its abandonment during the 5th century., The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency., Tottenham Hale is a district in the London Borough of Haringey in north London. From 18501965, it was part of the Municipal Borough of Tottenham, in Middlesex., The London Underground (also known simply as the Underground, or by its nickname the Tube) is a public rapid transit system serving Greater London and some parts of the adjacent counties of Buckinghamshire, Essex and Hertfordshire in the United Kingdom., Hertfordshire (often abbreviated Herts) is a county in southern England, bordered by Bedfordshire to the north, Cambridgeshire to the north-east, Essex to the east, Buckinghamshire to the west and Greater London to the south. For government statistical purposes, it is placed in the East of England region., The Mayor of London is an elected politician who, along with the London Assembly of 25 members, is accountable for the strategic government of Greater London. The current mayor is Sadiq Khan, who took up office on 9 May 2016. The position had been held by Ken Livingstone from the creation of the role on 4 May 2000 until he was defeated in 2008 by Boris Johnson, who served two terms before being succeeded by Khan., Great Britain, also known as Britain , is a large island in the north Atlantic Ocean off the northwest coast of continental Europe. With an area of , Great Britain is the largest European island and the ninth-largest in the world. In 2011 the island had a population of about 61 million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan. The island of Ireland is situated to the west of it, and together these islands, along with over 1,000 smaller surrounding islands, comprise the British Isles archipelago., 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., The Victoria line is a deep-level London Underground route running from Brixton in the south in Zone 2 to Walthamstow Central in the north-east in Zone 3 of London. It is coloured light blue on the Tube map. It is one of two underground lines to run entirely below ground, the other being the Waterloo & City line. Constructed in the 1960s, it was the first entirely new tube line in London for fifty years, and was designed to relieve congestion on other lines, in particular the Piccadilly line and the Charing Cross branch of the Northern line. The line has always been operated using automatic train operation, but all trains carry drivers., The London Assembly is an elected body, part of the Greater London Authority, that scrutinises the activities of the Mayor of London and has the power, with a two-thirds majority, to amend the Mayor's annual budget and to reject the Mayor's draft statutory strategies. The assembly was established in 2000 and meets at City Hall on the South Bank of the River Thames, close to Tower Bridge. The assembly is also able to investigate other issues of importance to Londoners (transport, environmental matters, etc.), publish its findings and recommendations, and make proposals to the Mayor., In Great Britain, National Rail is the trading name licensed for use by the Rail Delivery Group, an unincorporated association whose membership consists of the passenger train operating companies (TOCs) of Great Britain that run the passenger services previously provided by the British Railways Board, from 1965 using the brand name British Rail. National Rail generally does not include services that do not have a BR history; this distinction is important because National Rail services share a ticketing structure and inter-availability that do not necessarily extend to other services. The name and the accompanying double arrow symbol are the intellectual property of the Secretary of State for Transport., British Railways (BR), which from 1965 traded as British Rail, was the operator of most of the rail transport in Great Britain between 1948 and 1997. It was formed from the nationalisation of the "Big Four" British railway companies and lasted until the gradual privatisation of British Rail, in stages between 1994 and 1997. Originally a trading brand of the Railway Executive of the British Transport Commission, it became an independent statutory corporation in 1962: the British Railways Board. , Subject: tottenham hale station, Relation: located_in_the_administrative_territorial_entity, Options: (A) atlantic ocean (B) berkshire (C) british isles (D) buckinghamshire (E) cable (F) central (G) cross (H) district (I) east london (J) east sussex (K) enfield (L) england (M) europe (N) european union (O) forest (P) greater london (Q) guildford (R) hertfordshire (S) hyde park (T) inner london (U) ireland (V) japan (W) java (X) kent (Y) kingston upon thames (Z) london ([) london borough of haringey (\) london borough of waltham forest (]) mainland (^) middlesex (_) north (`) north east (a) northamptonshire (b) northern (c) northwest (d) of (e) oxfordshire (f) piccadilly (g) river (h) road (i) south (j) south east england (k) split (l) strand (m) street (n) surrey (o) sussex (p) united kingdom (q) victoria (r) wales (s) waltham (t) walthamstow (u) waterloo (v) west (w) westminster (x) whitehall

Context: Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) (= short, = tail), usually entirely hidden under the thorax. They live in all the world's oceans, in fresh water, and on land, are generally covered with a thick exoskeleton and have a single pair of claws. Many other animals with similar names  such as hermit crabs, king crabs, porcelain crabs, horseshoe crabs, and crab lice  are not true crabs., King crabs are a superfamily of crab-like decapod crustaceans chiefly found in cold seas. Because of their large size and the taste of their meat, many species are widely caught and sold as food, the most common being the red king crab ("Paralithodes camtschaticus")., Raninoida is a taxonomic section of the crabs, containing a single superfamily, Raninoidea. This group of crabs is unlike most, with the abdomen not being folded under the thorax. It comprises 46 extant species, and nearly 200 species known only from fossils., Hermit crabs are decapod crustaceans of the superfamily Paguroidea., An exoskeleton (from Greek , "éx" "outer" and , "skeletos" "skeleton") is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton (endoskeleton) of, for example, a human. In usage, some of the larger kinds of exoskeletons are known as "shells". Examples of animals with exoskeletons include insects such as grasshoppers and cockroaches, and crustaceans such as crabs and lobsters. The shells of certain sponges and the various groups of shelled molluscs, including those of snails, clams, tusk shells, chitons and nautilus, are also exoskeletons. Some animals, such as the tortoise, have both an endoskeleton and an exoskeleton., The tail is the section at the rear end of an animal's body; in general, the term refers to a distinct, flexible appendage to the torso. It is the part of the body that corresponds roughly to the sacrum and coccyx in mammals, reptiles, and birds. While tails are primarily a feature of vertebrates, some invertebrates including scorpions and springtails, as well as snails and slugs, have tail-like appendages that are sometimes referred to as tails. Tailed objects are sometimes referred to as "caudate" and the part of the body associated with or proximal to the tail are given the adjective "caudal"., In some taxonomic systems, Podotremata is the smaller of the two sections making up the crabs (Brachyura). Morphological and molecular analyses do not reveal a monophyletic Podotremata, and so the most recent classifications divide "Podotremata" into three sections: Dromiacea, Cyclodorippoidea and Raninoida., The abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The region occupied by the abdomen is termed the abdominal cavity. In arthropods it is the posterior tagma of the body; it follows the thorax or cephalothorax. The abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim. The pelvic brim stretches from the lumbosacral joint (the intervertebral disc between L5 and S1) to the pubic symphysis and is the edge of the pelvic inlet. The space above this inlet and under the thoracic diaphragm is termed the abdominal cavity. The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear., Dromiacea is a group of crabs , ranked as a section . It contains 240 extant and nearly 300 extinct species . Where they are considered to form a monophyletic group , Dromiacea and two other groups of crabs , namely the Raninoida and Cyclodorippoidea , may be collected together into the Podotremata , each at the rank of subsection ; morphological and molecular evidence argue against such a grouping . The larvae of Dromiacea resemble those of the Anomura more closely than those of other crabs . This may simply reflect their basal position in the crab phylogeny . The fossil record of Dromiacea reaches back at least as far as the Jurassic , and , if Imocaris is indeed a member , into the Carboniferous . The superfamily Eocarcinoidea , containing Eocarcinus and Platykotta , was previously considered to be a member of the Dromiacea , but has since been transferred to the Anomura ., Horseshoe crabs are marine arthropods of the family Limulidae and order Xiphosura or Xiphosurida, that live primarily in and around shallow ocean waters on soft sandy or muddy bottoms. They occasionally come onto shore to mate. They are commonly used as bait and in fertilizer. In recent years, a decline in the population has occurred as a consequence of coastal habitat destruction in Japan and overharvesting along the east coast of North America. Tetrodotoxin may be present in the roe of species inhabiting the waters of Thailand. Because of their origin 450 million years ago (Mya), horseshoe crabs are considered living fossils., The thorax or chest (from the Greek  "thorax" "breastplate, cuirass, corslet" via ) is a part of the anatomy of humans and various other animals located between the neck and the abdomen. The thorax includes the thoracic cavity and the thoracic wall. It contains organs including the heart, lungs, and thymus gland, as well as muscles and various other internal structures. Many diseases may affect the chest, and one of the most common symptoms is chest pain., Subject: dromiacea, Relation: parent_taxon, Options: (A) animal (B) brachyura (C) hermit (D) human (E) insects (F) king crab (G) mya (H) paralithodes (I) thorax (J) tortoise (K) xiphosura
