Osaka is a designated city in the Kansai region of Japan. It is the capital city of Osaka Prefecture and the largest component of the Keihanshin Metropolitan Area, the second largest metropolitan area in Japan and among the largest in the world with over 19 million inhabitants. Osaka will host Expo 2025; the current mayor of Osaka is Ichiro Matsui. Some of the earliest signs of human habitation in the Osaka area at the Morinomiya ruins comprise shell mounds, sea oysters and buried human skeletons from the 6th–5th centuries BC, it is believed that what is today the Uehonmachi area consisted of a peninsular land with an inland sea in the east. During the Yayoi period, permanent habitation on the plains grew. By the Kofun period, Osaka developed into a hub port connecting the region to the western part of Japan; the large numbers of larger tomb mounds found in the plains of Osaka are seen as evidence of political-power concentration, leading to the formation of a state. The Kojiki records that during 390–430 AD there was an imperial palace located at Osumi, in what is present day Higashiyodogawa ward, but it may have been a secondary imperial residence rather than a capital.
In 645, Emperor Kōtoku built his Naniwa Nagara-Toyosaki Palace in what is now Osaka, making it the capital of Japan. The city now known as Osaka was at this time referred to as Naniwa, this name and derivations of it are still in use for districts in central Osaka such as Naniwa and Namba. Although the capital was moved to Asuka in 655, Naniwa remained a vital connection, by land and sea, between Yamato and China. Naniwa was declared the capital again in 744 by order of Emperor Shōmu, remained so until 745, when the Imperial Court moved back to Heijō-kyō. By the end of the Nara period, Naniwa's seaport roles had been taken over by neighboring areas, but it remained a lively center of river and land transportation between Heian-kyō and other destinations. In 1496, Jōdo Shinshū Buddhists established their headquarters in the fortified Ishiyama Hongan-ji, located directly on the site of the old Naniwa Imperial Palace. Oda Nobunaga began a decade-long siege campaign on the temple in 1570 which resulted in the surrender of the monks and subsequent razing of the temple.
Toyotomi Hideyoshi constructed Osaka Castle in its place in 1583. Osaka was long considered Japan's primary economic center, with a large percentage of the population belonging to the merchant class. Over the course of the Edo period, Osaka grew into one of Japan's major cities and returned to its ancient role as a lively and important port, its popular culture was related to ukiyo-e depictions of life in Edo. By 1780, Osaka had cultivated a vibrant arts culture, as typified by its famous Kabuki and Bunraku theaters. In 1837, Ōshio Heihachirō, a low-ranking samurai, led a peasant insurrection in response to the city's unwillingness to support the many poor and suffering families in the area. One-quarter of the city was razed before shogunal officials put down the rebellion, after which Ōshio killed himself. Osaka was opened to foreign trade by the government of the Bakufu at the same time as Hyōgo on 1 January 1868, just before the advent of the Boshin War and the Meiji Restoration. Osaka residents were stereotyped in Edo literature from at least the 18th century.
Jippensha Ikku in 1802 depicted Osakans as stingy beyond belief. In 1809, the derogatory term "Kamigata zeeroku" was used by Edo residents to characterize inhabitants of the Osaka region in terms of calculation, lack of civic spirit, the vulgarity of Osaka dialect. Edo writers aspired to samurai culture, saw themselves as poor but generous and public spirited. Edo writers by contrast saw "zeeroku" as obsequious apprentices, greedy and lewd. To some degree, Osaka residents are still stigmatized by Tokyo observers in the same way today in terms of gluttony, evidenced in the phrase, "Residents of Osaka devour their food until they collapse"; the modern municipality was established in 1889 by government ordinance, with an initial area of 15 square kilometres, overlapping today's Chūō and Nishi wards. The city went through three major expansions to reach its current size of 223 square kilometres. Osaka was the industrial center most defined in the development of capitalism in Japan, it became known as the "Manchester of the Orient."The rapid industrialization attracted many Korean immigrants, who set up a life apart for themselves.
The political system was pluralistic, with a strong emphasis on promoting industrialization and modernization. Literacy was high and the educational system expanded producing a middle class with a taste for literature and a willingness to support the arts. In 1927, General Motors operated a factory called Osaka Assembly until 1941, manufacturing Chevrolet, Pontiac and Buick vehicles and staffed by Japanese workers and managers. In the nearby city of Ikeda in Osaka Prefecture is the headquarters office of Daihatsu, one of Japan's oldest automobile manufacturers. Like its European and American counterparts, Osaka displayed slums and poverty. In Japan it was here that municipal government first introduced a comprehensive system of poverty relief, copied in part from British models. Osaka policymakers stressed the importance of family formation and mutual assistance as the best way to combat poverty; this minimized
Okinawa Prefecture is the southernmost prefecture of Japan. It encompasses two thirds of the Ryukyu Islands in a chain over 1,000 kilometres long; the Ryukyu Islands extend southwest from Kagoshima Prefecture in Kyushu to Taiwan. Naha, Okinawa's capital, is located in the southern part of Okinawa Island. Although Okinawa Prefecture comprises just 0.6 percent of Japan's total land mass, about 75 percent of all United States military personnel stationed in Japan are assigned to installations in the prefecture. About 26,000 U. S. troops are based in the prefecture. The oldest evidence of human existence on the Ryukyu islands is from the Stone Age and was discovered in Naha and Yaeyama; some human bone fragments from the Paleolithic era were unearthed from a site in Naha, but the artifact was lost in transportation before it was examined to be Paleolithic or not. Japanese Jōmon influences are dominant on the Okinawa Islands, although clay vessels on the Sakishima Islands have a commonality with those in Taiwan.
The first mention of the word Ryukyu was written in the Book of Sui. Okinawa was the Japanese word identifying the islands, first seen in the biography of Jianzhen, written in 779. Agricultural societies begun in the 8th century developed until the 12th century. Since the islands are located at the eastern perimeter of the East China Sea close to Japan and South-East Asia, the Ryukyu Kingdom became a prosperous trading nation. During this period, many Gusukus, similar to castles, were constructed; the Ryukyu Kingdom entered into the Imperial Chinese tributary system under the Ming dynasty beginning in the 15th century, which established economic relations between the two nations. In 1609, the Shimazu clan, which controlled the region, now Kagoshima Prefecture, invaded the Ryukyu Kingdom; the Ryukyu Kingdom was obliged to agree to form a suzerain-vassal relationship with the Satsuma and the Tokugawa shogunate, while maintaining its previous role within the Chinese tributary system. The Satsuma clan earned considerable profits from trade with China during a period in which foreign trade was restricted by the shogunate.
Although Satsuma maintained strong influence over the islands, the Ryukyu Kingdom maintained a considerable degree of domestic political freedom for over two hundred years. Four years after the 1868 Meiji Restoration, the Japanese government, through military incursions annexed the kingdom and renamed it Ryukyu han. At the time, the Qing Empire asserted a nominal suzerainty over the islands of the Ryukyu Kingdom, since the Ryūkyū Kingdom was a member state of the Chinese tributary system. Ryukyu han became Okinawa Prefecture of Japan in 1879 though all other hans had become prefectures of Japan in 1872. In 1912, Okinawans first obtained the right to vote for representatives to the National Diet, established in 1890. Near the end of World War II, in 1945, the US Army and Marine Corps invaded Okinawa with 185,000 troops. A third of the civilian population died; the dead, of all nationalities, are commemorated at the Cornerstone of Peace. After the end of World War II, the Ryukyu independence movement developed, while Okinawa was under United States Military Government of the Ryukyu Islands administration for 27 years.
During this "trusteeship rule", the United States established numerous military bases on the Ryukyu islands. During the Korean War, B-29 Superfortresses flew bombing missions over Korea from Kadena Air Base on Okinawa; the military buildup on the island during the Cold War increased a division between local inhabitants and the American military. Under the 1952 Treaty of Mutual Cooperation and Security between the United States and Japan, the United States Forces Japan have maintained a large military presence. Since 1960, the U. S. and Japan have maintained an agreement that allows the U. S. to secretly bring nuclear weapons into Japanese ports. The Japanese tended to oppose the introduction of nuclear arms into Japanese territory by the government's assertion of Japan's non-nuclear policy and a statement of the Three Non-Nuclear Principles. Most of the weapons were alleged to be stored in ammunition bunkers at Kadena Air Base. Between 1954 and 1972, 19 different types of nuclear weapons were deployed in Okinawa, but with fewer than around 1,000 warheads at any one time.
Between 1965 and 1972, Okinawa was a key staging point for the United States in its military operations directed towards North Vietnam. Along with Guam, it presented a geographically strategic launch pad for covert bombing missions over Cambodia and Laos. Anti-Vietnam War sentiment became linked politically to the movement for reversion of Okinawa to Japan. In 1965, the US military bases, earlier viewed as paternal post war protection, were seen as aggressive; the Vietnam War highlighted the differences between the United States and Okinawa, but showed a commonality between the islands and mainland Japan. As controversy grew regarding the alleged placement of nuclear weapons on Okinawa, fears intensified over the escalation of the Vietnam War. Okinawa was perceived, by some inside Japan, as a potential target for China, should the communist government feel threatened by the United States. American military secrecy blocked any local reporting on what was occurring at bases such as Kadena Air Base.
As information leaked out, images of air strikes were published, the local population began to fear the potential for retaliation. Political leaders such as Oda Makoto
The Pacific Ocean is the largest and deepest of Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by Asia and Australia in the west and the Americas in the east. At 165,250,000 square kilometers in area, this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about one-third of its total surface area, making it larger than all of Earth's land area combined; the centers of both the Water Hemisphere and the Western Hemisphere are in the Pacific Ocean. The equator subdivides it into the North Pacific Ocean and South Pacific Ocean, with two exceptions: the Galápagos and Gilbert Islands, while straddling the equator, are deemed wholly within the South Pacific, its mean depth is 4,000 meters. The Mariana Trench in the western North Pacific is the deepest point in the world, reaching a depth of 10,911 meters; the western Pacific has many peripheral seas. Though the peoples of Asia and Oceania have traveled the Pacific Ocean since prehistoric times, the eastern Pacific was first sighted by Europeans in the early 16th century when Spanish explorer Vasco Núñez de Balboa crossed the Isthmus of Panama in 1513 and discovered the great "southern sea" which he named Mar del Sur.
The ocean's current name was coined by Portuguese explorer Ferdinand Magellan during the Spanish circumnavigation of the world in 1521, as he encountered favorable winds on reaching the ocean. He called it Mar Pacífico, which in both Portuguese and Spanish means "peaceful sea". Important human migrations occurred in the Pacific in prehistoric times. About 3000 BC, the Austronesian peoples on the island of Taiwan mastered the art of long-distance canoe travel and spread themselves and their languages south to the Philippines and maritime Southeast Asia. Long-distance trade developed all along the coast from Mozambique to Japan. Trade, therefore knowledge, extended to the Indonesian islands but not Australia. By at least 878 when there was a significant Islamic settlement in Canton much of this trade was controlled by Arabs or Muslims. In 219 BC Xu Fu sailed out into the Pacific searching for the elixir of immortality. From 1404 to 1433 Zheng He led expeditions into the Indian Ocean; the first contact of European navigators with the western edge of the Pacific Ocean was made by the Portuguese expeditions of António de Abreu and Francisco Serrão, via the Lesser Sunda Islands, to the Maluku Islands, in 1512, with Jorge Álvares's expedition to southern China in 1513, both ordered by Afonso de Albuquerque from Malacca.
The east side of the ocean was discovered by Spanish explorer Vasco Núñez de Balboa in 1513 after his expedition crossed the Isthmus of Panama and reached a new ocean. He named it Mar del Sur because the ocean was to the south of the coast of the isthmus where he first observed the Pacific. In 1519, Portuguese explorer Ferdinand Magellan sailed the Pacific East to West on a Spanish expedition to the Spice Islands that would result in the first world circumnavigation. Magellan called the ocean Pacífico because, after sailing through the stormy seas off Cape Horn, the expedition found calm waters; the ocean was called the Sea of Magellan in his honor until the eighteenth century. Although Magellan himself died in the Philippines in 1521, Spanish Basque navigator Juan Sebastián Elcano led the remains of the expedition back to Spain across the Indian Ocean and round the Cape of Good Hope, completing the first world circumnavigation in a single expedition in 1522. Sailing around and east of the Moluccas, between 1525 and 1527, Portuguese expeditions discovered the Caroline Islands, the Aru Islands, Papua New Guinea.
In 1542–43 the Portuguese reached Japan. In 1564, five Spanish ships carrying 379 explorers crossed the ocean from Mexico led by Miguel López de Legazpi, sailed to the Philippines and Mariana Islands. For the remainder of the 16th century, Spanish influence was paramount, with ships sailing from Mexico and Peru across the Pacific Ocean to the Philippines via Guam, establishing the Spanish East Indies; the Manila galleons operated for two and a half centuries, linking Manila and Acapulco, in one of the longest trade routes in history. Spanish expeditions discovered Tuvalu, the Marquesas, the Cook Islands, the Solomon Islands, the Admiralty Islands in the South Pacific. In the quest for Terra Australis, Spanish explorations in the 17th century, such as the expedition led by the Portuguese navigator Pedro Fernandes de Queirós, discovered the Pitcairn and Vanuatu archipelagos, sailed the Torres Strait between Australia and New Guinea, named after navigator Luís Vaz de Torres. Dutch explorers, sailing around southern Africa engaged in discovery and trade.
In the 16th and 17th centuries Spain considered the Pacific Ocean a mare clausum—a sea closed to other naval powers. As the only known entrance from the Atlantic, the Strait of Magellan was at times patrolled by fleets sent to prevent entrance of non-Spanish ships. On the western side of the Pacific Ocean the Dutch threatened the Spanish Philippines; the 18th cen
Shanghai is one of the four municipalities under the direct administration of the central government of the People's Republic of China, the largest city in China by population, the second most populous city proper in the world, with a population of 24.18 million as of 2017. It is a transport hub, with the world's busiest container port. Located in the Yangtze River Delta, it sits on the south edge of the estuary of the Yangtze in the middle portion of the East China coast; the municipality borders the provinces of Jiangsu and Zhejiang to the north and west, is bounded to the east by the East China Sea. As a major administrative and trading city, Shanghai grew in importance in the 19th century due to trade and recognition of its favourable port location and economic potential; the city was one of five treaty ports forced open to foreign trade following the British victory over China in the First Opium War. The subsequent 1842 Treaty of Nanking and 1844 Treaty of Whampoa allowed the establishment of the Shanghai International Settlement and the French Concession.
The city flourished as a centre of commerce between China and other parts of the world, became the primary financial hub of the Asia-Pacific region in the 1930s. During the World War II, the city was the site of the major Battle of Shanghai. After the war, with the Communist Party takeover of the mainland in 1949, trade was limited to other socialist countries, the city's global influence declined. In the 1990s, the economic reforms introduced by Deng Xiaoping resulted in an intense re-development of the city, aiding the return of finance and foreign investment to the city, it has since re-emerged as a hub for international finance. Shanghai has been described as the "showpiece" of the booming economy of mainland China; the two Chinese characters in the city's name are 上 and 海, together meaning "Upon-the-Sea". The earliest occurrence of this name dates from the 11th-century Song dynasty, at which time there was a river confluence and a town with this name in the area. There are disputes as to how the name should be understood, but Chinese historians have concluded that during the Tang dynasty Shanghai was on the sea.
Shanghai is abbreviated 沪 in Chinese, a contraction of 沪渎, a 4th- or 5th-century Jin name for the mouth of Suzhou Creek when it was the main conduit into the ocean. This character appears on all motor vehicle license plates issued in the municipality today. Another alternative name for Shanghai is Shēn or Shēnchéng, from Lord Chunshen, a 3rd-century BC nobleman and prime minister of the state of Chu, whose fief included modern Shanghai. Sports teams and newspapers in Shanghai use Shen in their names, such as Shanghai Shenhua F. C. and Shen Bao. Huating was another early name for Shanghai. In AD 751, during the mid-Tang dynasty, Huating County was established by the Governor of Wu Commandery Zhao Juzhen at modern-day Songjiang, the first county-level administration within modern-day Shanghai. Today, Huating appears as the name of a four-star hotel in the city; the city has various nicknames in English, including "Pearl of the Orient" and "Paris of the East". During the Spring and Autumn period, the Shanghai area belonged to the Kingdom of Wu, conquered by the Kingdom of Yue, which in turn was conquered by the Kingdom of Chu.
During the Warring States period, Shanghai was part of the fief of Lord Chunshen of Chu, one of the Four Lords of the Warring States. He ordered the excavation of the Huangpu River, its former or poetic name, the Chunshen River, gave Shanghai its nickname of "Shēn". Fishermen living in the Shanghai area created a fish tool called the hù, which lent its name to the outlet of Suzhou Creek north of the Old City and became a common nickname and abbreviation for the city. During the Tang and Song dynasties, Qinglong Town in modern Qingpu District was a major trading port. Established in 746, it developed into what contemporary sources called a "giant town of the Southeast", with thirteen temples and seven pagodas; the famous Song scholar and artist Mi Fu served as its mayor. The port had a thriving trade with provinces along the Yangtze River and the Chinese coast, as well as foreign countries such as Japan and Silla. By the end of the Song dynasty, the center of trading had moved downstream of the Wusong River to Shanghai, upgraded in status from a village to a market town in 1074, in 1172 a second sea wall was built to stabilize the ocean coastline, supplementing an earlier dike.
From the Yuan dynasty in 1292 until Shanghai became a municipality in 1927, central Shanghai was administered as a county under Songjiang Prefecture, whose seat was at the present-day Songjiang District. Two important events helped promote Shanghai's development in the Ming dynasty. A city wall was built for the first time in 1554 to protect the town from raids by Japanese pirates, it measured 10 metres high and 5 kilometres in circumference. During the Wanli reign, Shanghai received an important psychological boost from the erection of a City God Temple in 1602; this honour was reserved for prefectural capitals and not given to a mere county seat such as Shang
Japan is an island country in East Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asian continent and stretches from the Sea of Okhotsk in the north to the East China Sea and the Philippine Sea in the south; the kanji that make up Japan's name mean "sun origin", it is called the "Land of the Rising Sun". Japan is a stratovolcanic archipelago consisting of about 6,852 islands; the four largest are Honshu, Hokkaido and Shikoku, which make up about ninety-seven percent of Japan's land area and are referred to as home islands. The country is divided into 47 prefectures in eight regions, with Hokkaido being the northernmost prefecture and Okinawa being the southernmost one; the population of 127 million is the world's tenth largest. 90.7 % of people live in cities. About 13.8 million people live in the capital of Japan. The Greater Tokyo Area is the most populous metropolitan area in the world with over 38 million people. Archaeological research indicates; the first written mention of Japan is in Chinese history texts from the 1st century AD.
Influence from other regions China, followed by periods of isolation from Western Europe, has characterized Japan's history. From the 12th century until 1868, Japan was ruled by successive feudal military shōguns who ruled in the name of the Emperor. Japan entered into a long period of isolation in the early 17th century, ended in 1853 when a United States fleet pressured Japan to open to the West. After nearly two decades of internal conflict and insurrection, the Imperial Court regained its political power in 1868 through the help of several clans from Chōshū and Satsuma – and the Empire of Japan was established. In the late 19th and early 20th centuries, victories in the First Sino-Japanese War, the Russo-Japanese War and World War I allowed Japan to expand its empire during a period of increasing militarism; the Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the Japanese surrender. Since adopting its revised constitution on May 3, 1947, during the occupation led by SCAP, the sovereign state of Japan has maintained a unitary parliamentary constitutional monarchy with an Emperor and an elected legislature called the National Diet.
Japan is a member of the ASEAN Plus mechanism, UN, the OECD, the G7, the G8, the G20, is considered a great power. Its economy is the world's third-largest by nominal GDP and the fourth-largest by purchasing power parity, it is the world's fourth-largest exporter and fourth-largest importer. Japan benefits from a skilled and educated workforce. Although it has renounced its right to declare war, Japan maintains a modern military with the world's eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a developed country with a high standard of living and Human Development Index, its population enjoys the highest life expectancy and third lowest infant mortality rate in the world, but is experiencing issues due to an aging population and low birthrate. Japan is renowned for its historical and extensive cinema, influential music industry, video gaming, rich cuisine and its major contributions to science and modern technology; the Japanese word for Japan is 日本, pronounced Nihon or Nippon and means "the origin of the sun".
The character nichi means "sun" or "day". The compound therefore means "origin of the sun" and is the source of the popular Western epithet "Land of the Rising Sun"; the earliest record of the name Nihon appears in the Chinese historical records of the Tang dynasty, the Old Book of Tang. At the end of the seventh century, a delegation from Japan requested that Nihon be used as the name of their country; this name may have its origin in a letter sent in 607 and recorded in the official history of the Sui dynasty. Prince Shōtoku, the Regent of Japan, sent a mission to China with a letter in which he called himself "the Emperor of the Land where the Sun rises"; the message said: "Here, I, the emperor of the country where the sun rises, send a letter to the emperor of the country where the sun sets. How are you". Prior to the adoption of Nihon, other terms such as Yamato and Wakoku were used; the term Wa is a homophone of Wo 倭, used by the Chinese as a designation for the Japanese as early as the third century Three Kingdoms period.
Another form of Wa, Wei in Chinese) was used for an early state in Japan called Nakoku during the Han dynasty. However, the Japanese disliked some connotation of Wa 倭, it was therefore replaced with the substitute character Wa, meaning "togetherness, harmony"; the English word Japan derives from the historical Chinese pronunciation of 日本. The Old Mandarin or early Wu Chinese pronunciation of Japan was recorded by Marco Polo as Cipangu. In modern Shanghainese, a Wu dialect, the pronunciation of characters 日本; the old Malay word for Japan, Japun or Japang, was borrowed from a southern coastal Chinese dialect Fukienese or Ningpo – and this Malay word was encountered by Portuguese traders in Southeast Asia in the 16th century. These Early Portuguese traders brought the word
Dolphin is a common name of aquatic mammals within the order Cetacea, arbitrarily excluding whales and porpoises. The term dolphin refers to the extant families Delphinidae, Platanistidae and Pontoporiidae, the extinct Lipotidae. There are 40 extant species named as dolphins. Dolphins range in size from the 1.7 m long and 50 kg Maui's dolphin to the 9.5 m and 10 t killer whale. Several species exhibit sexual dimorphism, they have two limbs that are modified into flippers. Though not quite as flexible as seals, some dolphins can travel at 55.5 km/h. Dolphins use their conical shaped teeth to capture fast moving prey, they have well-developed hearing, adapted for both air and water and is so well developed that some can survive if they are blind. Some species are well adapted for diving to great depths, they have a layer of blubber, under the skin to keep warm in the cold water. Although dolphins are widespread, most species prefer the warmer waters of the tropic zones, but some, like the right whale dolphin, prefer colder climates.
Dolphins feed on fish and squid, but a few, like the killer whale, feed on large mammals, like seals. Male dolphins mate with multiple females every year, but females only mate every two to three years. Calves are born in the spring and summer months and females bear all the responsibility for raising them. Mothers of some species fast and nurse their young for a long period of time. Dolphins produce a variety of vocalizations in the form of clicks and whistles. Dolphins are sometimes hunted in places such as Japan, in an activity known as dolphin drive hunting. Besides drive hunting, they face threats from bycatch, habitat loss, marine pollution. Dolphins have been depicted in various cultures worldwide. Dolphins feature in literature and film, as in the film series Free Willy. Dolphins are sometimes trained to perform tricks; the most common dolphin species in captivity is the bottlenose dolphin, while there are around 60 captive killer whales. The name is from Greek δελφίς, "dolphin", related to the Greek δελφύς, "womb".
The animal's name can therefore be interpreted as meaning "a'fish' with a womb". The name was transmitted via the Latin delphinus, which in Medieval Latin became dolfinus and in Old French daulphin, which reintroduced the ph into the word; the term mereswine has historically been used. The term'dolphin' can be used to refer to, under the parvorder Odontoceti, all the species in the family Delphinidae and the river dolphin families Iniidae, Pontoporiidae and Platanistidae; this term has been misused in the US in the fishing industry, where all small cetaceans are considered porpoises, while the fish dorado is called dolphin fish. In common usage the term'whale' is used only for the larger cetacean species, while the smaller ones with a beaked or longer nose are considered'dolphins'; the name'dolphin' is used casually as a synonym for bottlenose dolphin, the most common and familiar species of dolphin. There are six species of dolphins thought of as whales, collectively known as blackfish: the killer whale, the melon-headed whale, the pygmy killer whale, the false killer whale, the two species of pilot whales, all of which are classified under the family Delphinidae and qualify as dolphins.
Though the terms'dolphin' and'porpoise' are sometimes used interchangeably, porpoises are not considered dolphins and have different physical features such as a shorter beak and spade-shaped teeth. Porpoises share a common ancestry with the Delphinidae. A group of dolphins is called a "school" or a "pod". Male dolphins are called "bulls", females "cows" and young dolphins are called "calves".

Canada is a country in the northern part of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres, making it the world's second-largest country by total area. Canada's southern border with the United States is the world's longest bi-national land border, its capital is Ottawa, its three largest metropolitan areas are Toronto and Vancouver. As a whole, Canada is sparsely populated, the majority of its land area being dominated by forest and tundra, its population is urbanized, with over 80 percent of its inhabitants concentrated in large and medium-sized cities, many near the southern border. Canada's climate varies across its vast area, ranging from arctic weather in the north, to hot summers in the southern regions, with four distinct seasons. Various indigenous peoples have inhabited what is now Canada for thousands of years prior to European colonization. Beginning in the 16th century and French expeditions explored, settled, along the Atlantic coast.
As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces; this began an accretion of provinces and territories and a process of increasing autonomy from the United Kingdom. This widening autonomy was highlighted by the Statute of Westminster of 1931 and culminated in the Canada Act of 1982, which severed the vestiges of legal dependence on the British parliament. Canada is a parliamentary democracy and a constitutional monarchy in the Westminster tradition, with Elizabeth II as its queen and a prime minister who serves as the chair of the federal cabinet and head of government; the country is a realm within the Commonwealth of Nations, a member of the Francophonie and bilingual at the federal level. It ranks among the highest in international measurements of government transparency, civil liberties, quality of life, economic freedom, education.
It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many other countries. Canada's long and complex relationship with the United States has had a significant impact on its economy and culture. A developed country, Canada has the sixteenth-highest nominal per capita income globally as well as the twelfth-highest ranking in the Human Development Index, its advanced economy is the tenth-largest in the world, relying chiefly upon its abundant natural resources and well-developed international trade networks. Canada is part of several major international and intergovernmental institutions or groupings including the United Nations, the North Atlantic Treaty Organization, the G7, the Group of Ten, the G20, the North American Free Trade Agreement and the Asia-Pacific Economic Cooperation forum. While a variety of theories have been postulated for the etymological origins of Canada, the name is now accepted as coming from the St. Lawrence Iroquoian word kanata, meaning "village" or "settlement".
In 1535, indigenous inhabitants of the present-day Quebec City region used the word to direct French explorer Jacques Cartier to the village of Stadacona. Cartier used the word Canada to refer not only to that particular village but to the entire area subject to Donnacona. From the 16th to the early 18th century "Canada" referred to the part of New France that lay along the Saint Lawrence River. In 1791, the area became two British colonies called Upper Canada and Lower Canada collectively named the Canadas. Upon Confederation in 1867, Canada was adopted as the legal name for the new country at the London Conference, the word Dominion was conferred as the country's title. By the 1950s, the term Dominion of Canada was no longer used by the United Kingdom, which considered Canada a "Realm of the Commonwealth"; the government of Louis St. Laurent ended the practice of using'Dominion' in the Statutes of Canada in 1951. In 1982, the passage of the Canada Act, bringing the Constitution of Canada under Canadian control, referred only to Canada, that year the name of the national holiday was changed from Dominion Day to Canada Day.
