Traditional classification divides fish into three extant classes (Agnatha, Chondrichthyes, and Osteichthyes), and with extinct forms sometimes classified within those groups, sometimes as their own classes. Fish account for more than half of vertebrate species. As of 2016, there are over 32,000 described species of bony fish, over 1,100 species of cartilaginous fish, and over 100 hagfish and lampreys. A third of these fall within

The Mughal Empire , in 1526, ushered in two centuries of relative peace, leaving a legacy of luminous architecture . Gradually expanding rule of the British East India Company followed, turning India into a colonial economy but also consolidating its sovereignty . British Crown rule began in 1858. The rights promised to Indians were granted slowly, but technological changes were introduced, and modern ideas of education and public life took root. A pioneering and influential nationalist movement emerged, which

In the 1950s, India strongly supported decolonisation in Africa and Asia and played a leading role in the Non-Aligned Movement . After initially cordial relations with neighbouring China, India went to war with China in 1962 and was widely thought to have been humiliated. This was followed by another military conflict in 1967 in which India successfully repelled Chinese attack. India has had tense relations with neighbouring Pakistan;
1950-441: A sense of touch and of hearing . Blind cave fish navigate almost entirely through the sensations from their lateral line system. Some fish, such as catfish and sharks, have the ampullae of Lorenzini , electroreceptors that detect weak electric currents on the order of millivolt. Vision is an important sensory system in fish. Fish eyes are similar to those of terrestrial vertebrates like birds and mammals, but have

Like other animals, fish suffer from parasitism . Some species use cleaner fish to remove external parasites. The best known of these are the bluestreak cleaner wrasses of coral reefs in the Indian and Pacific oceans. These small fish maintain cleaning stations where other fish congregate and perform specific movements to attract
2550-422: A typical fish is adapted for efficient swimming by alternately contracting paired sets of muscles on either side of the backbone. These contractions form S-shaped curves that move down the body. As each curve reaches the tail fin, force is applied to the water, moving the fish forward. The other fins act as control surfaces like an aircraft's flaps, enabling the fish to steer in any direction. Since body tissue

Males are typically larger and heavier than females, with the nominate race P. c. carbo averaging about 10% larger in linear measurements than the smaller subspecies P. c. sinensis . The lightest average weights cited are in Germany ( P. c. sinensis ), where 36 males averaged 2.28 kg (5 lb 1 ⁄ 2 oz) and 17 females averaged 1.94 kg (4 lb 4 + 1 ⁄ 2 oz). The highest come from Prince Edward Island in Canada ( P. c. carbo ), where 11 males averaged 3.68 kg (8 lb 2 oz) and 11 females averaged 2.94 kg (6 lb 7 + 1 ⁄ 2 oz). Length can vary from 70 to 102 cm ( 27 + 1 ⁄ 2 to 40 in) and wingspan from 121 to 160 cm ( 47 + 1 ⁄ 2 to 63 in). They are tied as

Some fish, including salmon, are capable of magnetoreception ; when the axis of a magnetic field is changed around a circular tank of young fish, they reorient themselves in line with the field. The mechanism of fish magnetoreception remains unknown; experiments in birds imply
3600-427: Is around 28 seconds, with the bird diving to depths of about 5.8 metres (19 ft 0 in). About 60% of dives are to the benthic zone and about 10% are to the pelagic zone , with the rest of the dives being to zones in between the two. Studies suggest that their hearing has evolved for underwater usage, possibly aiding their detection of fish. These adaptations also have a cost on their hearing ability in air which
3750-631: Is caused by albinism . Albinos suffer from poor eyesight and/or hearing, thus it rarely manages to survive in the wild. This is a very common and widespread bird species. It feeds on the sea, in estuaries , and on freshwater lakes and rivers. Northern birds migrate south and winter along any coast that is well-supplied with fish . In Serbia, the cormorant lives in Vojvodina. However, after 1945 many artificial lakes were formed in Serbia; some of them became potential habitats for cormorants. Currently, on

Many bony fish have an internal organ called a swim bladder that allows them to adjust their buoyancy by increasing or decreasing the amount of gas it contains. The scales of fish provide protection from predators at the cost of adding stiffness and weight. Fish scales are often highly reflective; this silvering provides camouflage in

According to a 2011 PricewaterhouseCoopers ( PwC ) report, India's GDP at purchasing power parity could overtake that of the United States by 2045. During the next four decades, Indian GDP is expected to grow at an annualised average of 8%, making it potentially the world's fastest-growing major economy until 2050. The report highlights key growth factors:
4350-624: Is indicated by the large number of megalithic monuments dating from this period, as well as by nearby traces of agriculture , irrigation tanks , and craft traditions. In the late Vedic period, around the 6th century BCE, the small states and chiefdoms of the Ganges Plain and the north-western regions had consolidated into 16 major oligarchies and monarchies that were known as the mahajanapadas . The emerging urbanisation gave rise to non-Vedic religious movements, two of which became independent religions. Jainism came into prominence during

Due to conservation efforts, its numbers increased. At the moment, there are about 1.2 million birds in Europe (based on winter counts; late summer counts would show higher numbers). Increasing populations have once again brought the cormorant into conflict with fisheries. For example, in Britain, where inland breeding

Again in the 2004 Indian general elections , no party won an absolute majority, but the Congress emerged as the largest single party, forming another successful coalition: the United Progressive Alliance (UPA). It had
10650-498: The Buddha is recorded in the Pali canon to have sought enlightenment. Many Indian species have descended from those of Gondwana , the southern supercontinent from which India separated more than 100 million years ago. India's subsequent collision with Eurasia set off a mass exchange of species. However, volcanism and climatic changes later caused the extinction of many endemic Indian forms. Still later, mammals entered India from Asia through two zoogeographic passes flanking
10800-656: The Buddhist dhamma . The Sangam literature of the Tamil language reveals that, between 200 BCE and 200 CE , the southern peninsula was ruled by the Cheras , the Cholas , and the Pandyas , dynasties that traded extensively with the Roman Empire and with West and Southeast Asia . In North India, Hinduism asserted patriarchal control within the family, leading to increased subordination of women. By
10950-685: The Congress saw a change in leadership in 1984, when Indira Gandhi was assassinated ; she was succeeded by her son Rajiv Gandhi , who won an easy victory in the general elections later that year . The Congress was voted out again in 1989 when a National Front coalition, led by the newly formed Janata Dal in alliance with the Left Front , won the elections; that government too proved relatively short-lived, lasting just under two years. There were two prime ministers during this period; V.P. Singh and Chandra Shekhar . Elections were held again in 1991 ; no party won an absolute majority. The Congress, as
11100-476: The East India Company set the stage for changes essential to a modern state. These included the consolidation and demarcation of sovereignty, the surveillance of the population, and the education of citizens. Technological changes—among them, railways, canals, and the telegraph—were introduced not long after their introduction in Europe . However, disaffection with the company also grew during this time and set off
11250-943: The Ganges include the Yamuna and the Kosi ; the latter's extremely low gradient, caused by long-term silt deposition, leads to severe floods and course changes. Major peninsular rivers, whose steeper gradients prevent their waters from flooding, include the Godavari , the Mahanadi , the Kaveri , and the Krishna , which also drain into the Bay of Bengal; and the Narmada and the Tapti , which drain into
11400-555: The Himalayas and the Thar Desert, both of which drive the economically and culturally pivotal summer and winter monsoons . The Himalayas prevent cold Central Asian katabatic winds from blowing in, keeping the bulk of the Indian subcontinent warmer than most locations at similar latitudes. The Thar Desert plays a crucial role in attracting the moisture-laden south-west summer monsoon winds that, between June and October, provide
11550-462: The Himalayas. This had the effect of lowering endemism among India's mammals, which stands at 12.6%, contrasting with 45.8% among reptiles and 55.8% among amphibians. Among endemics are the vulnerable hooded leaf monkey and the threatened Beddome's toad of the Western Ghats. India contains 172 IUCN -designated threatened animal species , or 2.9% of endangered forms. These include
11700-401: The Indian elites, the sultanate largely left its vast non-Muslim subject population to its own laws and customs. By repeatedly repulsing Mongol raiders in the 13th century, the sultanate saved India from the devastation visited on West and Central Asia, setting the scene for centuries of migration of fleeing soldiers, learned men, mystics, traders, artists, and artisans from that region into
11850-577: The Lake Ćelije , formed in 1980, there is a resident colony of cormorants, who nest there and are present throughout the year, except January–February 1985 and February 2012 when the lake surface was completely frozen. The type subspecies, P. c. carbo , is found mainly in Atlantic waters and nearby inland areas: on western European coasts and east across the Palearctic to Siberia and to North Africa,
12000-624: The Late Paleozoic , evolved from lobe-finned fish during the Carboniferous , developing air-breathing lungs homologous to swim bladders. Despite the cladistic lineage, tetrapods are usually not considered to be fish, making "fish" a paraphyletic group. Fish have been an important natural resource for humans since prehistoric times, especially as food . Commercial and subsistence fishers harvest fish in wild fisheries or farm them in ponds or in breeding cages in
12150-463: The Mughals united their far-flung realms through loyalty, expressed through a Persianised culture, to an emperor who had near-divine status. The Mughal state's economic policies, deriving most revenues from agriculture and mandating that taxes be paid in the well-regulated silver currency, caused peasants and artisans to enter larger markets. The relative peace maintained by the empire during much of
12300-601: The Southern Ocean, including under the Filchner–Ronne Ice Shelf at a latitude of 79°S, while desert pupfish live in desert springs, streams, and marshes, sometimes highly saline, with water temperatures as high as 36 C. A few fish live mostly on land or lay their eggs on land near water. Mudskippers feed and interact with one another on mudflats and go underwater to hide in their burrows. A single undescribed species of Phreatobius has been called
12450-557: The advent of independence in 1947, but tempered by the partition of India into two states: India and Pakistan. Vital to India's self-image as an independent nation was its constitution, completed in 1950, which put in place a secular and democratic republic. Per the London Declaration , India retained its membership of the Commonwealth , becoming the first republic within it. Economic liberalisation, which began in
12600-512: The agricultural sector 18.1%. India's foreign exchange remittances of US$ 100 billion in 2022, highest in the world, were contributed to its economy by 32 million Indians working in foreign countries. Major agricultural products include rice, wheat, oilseed, cotton, jute, tea, sugarcane, and potatoes. Major industries include textiles, telecommunications, chemicals, pharmaceuticals, biotechnology, food processing, steel, transport equipment, cement, mining, petroleum, machinery, and software. In 2006,
12750-556: The attention of the cleaners. Cleaning behaviors have been observed in a number of fish groups, including an interesting case between two cichlids of the same genus, Etroplus maculatus , the cleaner, and the much larger E. suratensis . Fish occupy many trophic levels in freshwater and marine food webs . Fish at the higher levels are predatory , and a substantial part of their prey consists of other fish. In addition, mammals such as dolphins and seals feed on fish, alongside birds such as gannets and cormorants . The body of
12900-498: The banking sector, 44th in business sophistication, and 39th in innovation, ahead of several advanced economies. With seven of the world's top 15 information technology outsourcing companies based in India, as of 2009 , the country is viewed as the second-most favourable outsourcing destination after the United States. India is ranked 39th in the Global Innovation Index in 2024. As of 2023 , India's consumer market
13050-608: The beginnings of a nonviolent movement of non-co-operation, of which Mahatma Gandhi would become the leader and enduring symbol. During the 1930s, slow legislative reform was enacted by the British; the Indian National Congress won victories in the resulting elections. The next decade was beset with crises: Indian participation in World War ;II , the Congress's final push for non-co-operation, and an upsurge of Muslim nationalism . All were capped by
13200-550: The body, and produce a concentrated urine. The reverse happens in freshwater fish : they tend to gain water osmotically, and produce a dilute urine. Some fish have kidneys able to operate in both freshwater and saltwater. Fish have small brains relative to body size compared with other vertebrates, typically one-fifteenth the brain mass of a similarly sized bird or mammal. However, some fish have relatively large brains, notably mormyrids and sharks , which have brains about as large for their body weight as birds and marsupials . At
13350-552: The breeding season. In European waters it can be distinguished from the common shag by its larger size, heavier build, thicker bill, lack of a crest and plumage without any green tinge. In eastern North America, it is similarly larger and bulkier than the double-crested cormorant ; the latter species also has more yellow on the throat and bill and lacks the white thigh patches frequently seen on great cormorants. Great cormorants are mostly silent, but they make various guttural noises at their breeding colonies. The white filoplumes on
13500-495: The coasts of southern and eastern India. As the empire disintegrated, many among these elites were able to seek and control their own affairs. By the early 18th century, with the lines between commercial and political dominance being increasingly blurred, a number of European trading companies, including the English East India Company , had established coastal outposts. The East India Company's control of
13650-452: The commercialisation of agriculture in the second half of the 19th century was marked by economic setbacks, and many small farmers became dependent on the whims of far-away markets. There was an increase in the number of large-scale famines , and, despite the risks of infrastructure development borne by Indian taxpayers, little industrial employment was generated for Indians. There were also salutary effects: commercial cropping, especially in
13800-625: The contribution of petrochemical and engineering goods to total exports grew from 14% to 42%. India was the world's second-largest textile exporter after China in the 2013 calendar year. Averaging an economic growth rate of 7.5% for several years prior to 2007, India has more than doubled its hourly wage rates during the first decade of the 21st century. Some 431 million Indians have left poverty since 1985; India's middle classes are projected to number around 580 million by 2030. Though ranking 68th in global competitiveness , as of 2010 , India ranks 17th in financial market sophistication, 24th in
13950-493: The cormorant is a traditional game bird. Each year approximately 10,000 cormorants are shot to be eaten. In North Norway, cormorants are traditionally seen as semi-sacred. It is regarded as good luck to have cormorants gather near your village or settlement. An old legend states that people who die far out at sea, whose bodies are never recovered, spend eternity on the island Utrøst – which can only occasionally be found by mortals. The inhabitants of Utrøst can only visit their homes in
14100-579: The cost of increasing economic inequality. India is a nuclear-weapon state , which ranks high in military expenditure . It has disputes over Kashmir with its neighbours, Pakistan and China, unresolved since the mid-20th century. Among the socio-economic challenges India faces are gender inequality , child malnutrition , and rising levels of air pollution . India's land is megadiverse , with four biodiversity hotspots . Its forest cover comprises 21.7% of its area. India's wildlife , which has traditionally been viewed with tolerance in India's culture ,
14250-581: The design and implementation of Vikrant -class aircraft carriers and Arihant -class nuclear submarines . Since the end of the Cold War , India has increased its economic, strategic, and military co-operation with the United States and the European Union . In 2008, a civilian nuclear agreement was signed between India and the United States. Although India possessed nuclear weapons at
14400-507: The early 16th century, northern India, then under mainly Muslim rulers, fell again to the superior mobility and firepower of a new generation of Central Asian warriors. The resulting Mughal Empire did not stamp out the local societies it came to rule. Instead, it balanced and pacified them through new administrative practices and diverse and inclusive ruling elites, leading to more systematic, centralised, and uniform rule. Eschewing tribal bonds and Islamic identity, especially under Akbar ,
14550-536: The early mediaeval era, Christianity , Islam , Judaism , and Zoroastrianism became established on India's southern and western coasts. Muslim armies from Central Asia intermittently overran India's northern plains, eventually founding the Delhi Sultanate and drawing northern India into the cosmopolitan networks of mediaeval Islam . In the 15th century, the Vijayanagara Empire created
14700-727: The east. To the south, the remaining peninsular landmass, the Deccan Plateau , is flanked on the west and east by coastal ranges known as the Western and Eastern Ghats ; the plateau contains the country's oldest rock formations, some over one billion years old. Constituted in such fashion, India lies to the north of the equator between 6° 44′ and 35° 30′ north latitude and 68° 7′ and 97° 25′ east longitude. India's coastline measures 7,517 kilometres (4,700 mi) in length; of this distance, 5,423 kilometres (3,400 mi) belong to peninsular India and 2,094 kilometres (1,300 mi) to
14850-513: The endangered Bengal tiger and the Ganges river dolphin . Critically endangered species include the gharial , a crocodilian ; the great Indian bustard ; and the Indian white-rumped vulture , which has become nearly extinct by having ingested the carrion of diclofenac -treated cattle. Before they were extensively used for agriculture and cleared for human settlement, the thorn forests of Punjab were mingled at intervals with open grasslands that were grazed by large herds of blackbuck preyed on by
15000-570: The exact root is unknown; some authorities reconstruct a Proto-Indo-European root * peysk- , attested only in Italic , Celtic , and Germanic . About 530 million years ago during the Cambrian explosion , fishlike animals with a notochord and eyes at the front of the body, such as Haikouichthys , appear in the fossil record . During the late Cambrian , other jawless forms such as conodonts appear. Jawed vertebrates appear in
15150-405: The front of the brain are the olfactory lobes , a pair of structures that receive and process signals from the nostrils via the two olfactory nerves . Fish that hunt primarily by smell, such as hagfish and sharks, have very large olfactory lobes. Behind these is the telencephalon , which in fish deals mostly with olfaction. Together these structures form the forebrain. Connecting the forebrain to
15300-412: The gills flows in the opposite direction to the water, resulting in efficient countercurrent exchange . The gills push the oxygen-poor water out through openings in the sides of the pharynx. Cartilaginous fish have multiple gill openings: sharks usually have five, sometimes six or seven pairs; they often have to swim to oxygenate their gills. Bony fish have a single gill opening on each side, hidden beneath
15450-532: The gills. Oxygen-rich blood then flows without further pumping, unlike in mammals, to the body tissues. Finally, oxygen-depleted blood returns to the heart. Fish exchange gases using gills on either side of the pharynx . Gills consist of comblike structures called filaments. Each filament contains a capillary network that provides a large surface area for exchanging oxygen and carbon dioxide . Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. Capillary blood in
15600-402: The globe. In this practice, fishermen tie a line around the throats of cormorants, tight enough to prevent swallowing the larger fish they catch, and deploy them from small boats. The cormorants catch fish without being able to fully swallow them, and the fishermen are able to retrieve the fish simply by forcing open the cormorants' mouths, apparently engaging the regurgitation reflex. In Norway,
15750-796: The ground on rocky islands that are free of predators. This cormorant lays a clutch of three to five eggs that measure 63 by 41 millimetres ( 2 + 1 ⁄ 2 by 1 + 5 ⁄ 8 in) on average. The eggs are a pale blue or green, and sometimes have a white chalky layer covering them. These eggs are incubated for a period of about 28 to 31 days. The great cormorant feeds on fish caught through diving. This bird feeds primarily on wrasses , but it also takes sand smelt , flathead and common soles . The average weight of fish taken by great cormorants increases with decreasing air and water temperature. Cormorants consume all fish of appropriate size that they are able to catch in summer and noticeably select for larger, mostly torpedo-shaped fish in winter. Thus,
15900-447: The gut, leading from the mouth to the anus. The mouth of most fishes contains teeth to grip prey, bite off or scrape plant material, or crush the food. An esophagus carries food to the stomach where it may be stored and partially digested. A sphincter, the pylorus, releases food to the intestine at intervals. Many fish have finger-shaped pouches, pyloric caeca , around the pylorus, of doubtful function. The pancreas secretes enzymes into
16050-407: The head in the breeding season vary with both the age of the bird, and the subspecies; older birds have more white filoplumes than younger birds, while nominate P. c. carbo tends to have fewer than P. c. sinensis , but there is much overlap. The extent of variation between individuals means it is not a very useful character for subspecies identification. A very rare variation of the great cormorant
16200-457: The heart from the rest of the body. Lungfish, bichirs, ropefish, bowfins, snakefish, and the African knifefish have evolved to reduce such mixing, and to reduce oxygen loss from the gills to oxygen-poor water. Bichirs and lungfish have tetrapod-like paired lungs, requiring them to surface to gulp air, and making them obligate air breathers. Many other fish, including inhabitants of rock pools and
16350-455: The intestine to digest the food; other enzymes are secreted directly by the intestine itself. The liver produces bile which helps to break up fat into an emulsion which can be absorbed in the intestine. Most fish release their nitrogenous wastes as ammonia . This may be excreted through the gills or filtered by the kidneys . Salt is excreted by the rectal gland. Saltwater fish tend to lose water by osmosis ; their kidneys return water to
16500-494: The largest single party, was able to form a minority government led by P. V. Narasimha Rao . A two-year period of political turmoil followed the general election of 1996 . Several short-lived alliances shared power at the centre. The BJP formed a government briefly in 1996; it was followed by two comparatively long-lasting United Front coalitions, which depended on external support. There were two prime ministers during this period; H.D. Deve Gowda and I.K. Gujral . In 1998 ,
16650-478: The life of its exemplar, Mahavira . Buddhism , based on the teachings of Gautama Buddha , attracted followers from all social classes excepting the middle class; chronicling the life of the Buddha was central to the beginnings of recorded history in India. In an age of increasing urban wealth, both religions held up renunciation as an ideal, and both established long-lasting monastic traditions. Politically, by
16800-526: The loose-knit Maurya and Gupta Empires based in the Ganges Basin . Their collective era was suffused with wide-ranging creativity, but also marked by the declining status of women, and the incorporation of untouchability into an organised system of belief. In South India , the Middle kingdoms exported Dravidian-languages scripts and religious cultures to the kingdoms of Southeast Asia . In
16950-471: The majority of India's rainfall. Four major climatic groupings predominate in India: tropical wet , tropical dry , subtropical humid , and montane . Temperatures in India have risen by 0.7 °C (1.3 °F) between 1901 and 2018. Climate change in India is often thought to be the cause. The retreat of Himalayan glaciers has adversely affected the flow rate of the major Himalayan rivers, including
17100-419: The midbrain is the diencephalon ; it works with hormones and homeostasis . The pineal body is just above the diencephalon; it detects light, maintains circadian rhythms, and controls color changes. The midbrain contains the two optic lobes . These are very large in species that hunt by sight, such as rainbow trout and cichlids . The hindbrain controls swimming and balance.The single-lobed cerebellum
17250-420: The nation to liberalise its economy ; since then, it has moved increasingly towards a free-market system by emphasising both foreign trade and direct investment inflows. India has been a member of World Trade Organization since 1 January 1995. The 522-million-worker Indian labour force is the world's second largest , as of 2017 . The service sector makes up 55.6% of GDP, the industrial sector 26.3% and
17400-445: The newly canalled Punjab, led to increased food production for internal consumption. The railway network provided critical famine relief, notably reduced the cost of moving goods, and helped nascent Indian-owned industry. After World War I , in which approximately one million Indians served , a new period began. It was marked by British reforms but also repressive legislation , by more strident Indian calls for self-rule, and by
17550-443: The nine largest families; from largest to smallest, these are Cyprinidae , Gobiidae , Cichlidae , Characidae , Loricariidae , Balitoridae , Serranidae , Labridae , and Scorpaenidae . About 64 families are monotypic , containing only one species. Fish range in size from the huge 16-metre (52 ft) whale shark to some tiny teleosts only 8-millimetre (0.3 in) long, such as the cyprinid Paedocypris progenetica and
17700-547: The north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives ; its Andaman and Nicobar Islands share a maritime border with Thailand , Myanmar, and Indonesia . Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago. Their long occupation, initially in varying forms of isolation as hunter-gatherers, has made
17850-682: The northwest. Its evidence today is found in the hymns of the Rigveda . Preserved by an oral tradition that was resolutely vigilant , the Rigveda records the dawning of Hinduism in India. The Dravidian languages of India were supplanted in the northern and western regions. By 400 BCE , stratification and exclusion by caste had emerged within Hinduism, and Buddhism and Jainism had arisen, proclaiming social orders unlinked to heredity. Early political consolidations gave rise to
18000-500: The ocean. Fish are caught for recreation , or raised by fishkeepers as ornaments for private and public exhibition in aquaria and garden ponds . Fish have had a role in human culture through the ages, serving as deities , religious symbols, and as the subjects of art, books and movies. The word fish is inherited from Proto-Germanic , and is related to German Fisch , the Latin piscis and Old Irish īasc , though
18150-402: The open ocean. Because the water all around is the same colour, reflecting an image of the water offers near-invisibility. Fish have a closed-loop circulatory system . The heart pumps the blood in a single loop throughout the body; for comparison, the mammal heart has two loops, one for the lungs to pick up oxygen, one for the body to deliver the oxygen. In fish, the heart pumps blood through
18300-546: The proportion of the area of a forest covered by its tree canopy . Very dense forest , whose canopy density is greater than 70%, occupies 3.02% of India's land area. It predominates in the tropical moist forest of the Andaman Islands , the Western Ghats , and Northeast India . Moderately dense forest , whose canopy density is between 40% and 70%, occupies 9.39% of India's land area. It predominates in
18450-450: The region highly diverse, second only to Africa in human genetic diversity . Settled life emerged on the subcontinent in the western margins of the Indus river basin 9,000 years ago, evolving gradually into the Indus Valley Civilisation of the third millennium BCE. By at least 1200 BCE , an archaic form of Sanskrit , an Indo-European language , had diffused into India from
18600-548: The seas, greater resources, and more advanced military training and technology led it to increasingly assert its military strength and caused it to become attractive to a portion of the Indian elite; these factors were crucial in allowing the company to gain control over the Bengal region by 1765 and sideline the other European companies. Its further access to the riches of Bengal and the subsequent increased strength and size of its army enabled it to annex or subdue most of India by
18750-521: The second largest extant species of cormorant after the flightless cormorant , with the Japanese cormorant averaging at a similar size. In bulk if not in linear dimensions, the blue-eyed shag species complex of the Southern Oceans are scarcely smaller at average. It has a longish tail and yellow throat-patch. Adults have white filoplume patches on the thighs and on the head and upper neck in
18900-640: The shape of cormorants. India India , officially the Republic of India , is a country in South Asia . It is the seventh-largest country in the world by area and the most populous country . Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China , Nepal , and Bhutan to
19050-463: The share of external trade in India's GDP stood at 24%, up from 6% in 1985. In 2008, India's share of world trade was 1.7%; In 2021, India was the world's ninth-largest importer and the sixteenth-largest exporter . Major exports include petroleum products, textile goods, jewellery, software, engineering goods, chemicals, and manufactured leather goods. Major imports include crude oil, machinery, gems, fertiliser, and chemicals. Between 2001 and 2011,
19200-524: The southern supercontinent Gondwana , began a north-eastward drift caused by seafloor spreading to its south-west, and later, south and south-east. Simultaneously, the vast Tethyan oceanic crust , to its northeast, began to subduct under the Eurasian Plate . These dual processes, driven by convection in the Earth's mantle , both created the Indian Ocean and caused the Indian continental crust eventually to under-thrust Eurasia and to uplift
19350-416: The subcontinent from the north-west. The caste system , which created a hierarchy of priests, warriors, and free peasants, but which excluded indigenous peoples by labelling their occupations impure, arose during this period. On the Deccan Plateau , archaeological evidence from this period suggests the existence of a chiefdom stage of political organisation. In South India , a progression to sedentary life
19500-526: The subcontinent transitioned from the Chalcolithic cultures to the Iron Age ones. The Vedas , the oldest scriptures associated with Hinduism , were composed during this period, and historians have analysed these to posit a Vedic culture in the Punjab region and the upper Gangetic Plain . Most historians also consider this period to have encompassed several waves of Indo-Aryan migration into
19650-441: The subcontinent, thereby creating a syncretic Indo-Islamic culture in the north. The sultanate's raiding and weakening of the regional kingdoms of South India paved the way for the indigenous Vijayanagara Empire . Embracing a strong Shaivite tradition and building upon the military technology of the sultanate, the empire came to control much of peninsular India, and was to influence South Indian society for long afterwards. In
19800-414: The support of left-leaning parties and MPs who opposed the BJP. The UPA returned to power in the 2009 general election with increased numbers, and it no longer required external support from India's communist parties . That year, Manmohan Singh became the first prime minister since Jawaharlal Nehru in 1957 and 1962 to be re-elected to a consecutive five-year term. In the 2014 general election ,
19950-507: The surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature . Many fish can communicate acoustically with each other, such as during courtship displays . The earliest fish appeared during the Cambrian as small filter feeders ; they continued to evolve through the Paleozoic , diversifying into many forms. The earliest fish with dedicated respiratory gills and paired fins ,
20100-415: The taxon Osteichthyes as a clade, which now includes all tetrapods". The biodiversity of extant fish is unevenly distributed among the various groups; teleosts , bony fishes able to protrude their jaws , make up 96% of fish species. The cladogram shows the evolutionary relationships of all groups of living fishes (with their respective diversity ) and the tetrapods. Extinct groups are marked with
20250-677: The time and was not a party to the Nuclear Non-Proliferation Treaty, it received waivers from the International Atomic Energy Agency and the Nuclear Suppliers Group , ending earlier restrictions on India's nuclear technology and commerce. As a consequence, India became the sixth de facto nuclear weapons state. India subsequently signed co-operation agreements involving civilian nuclear energy with Russia, France,
20400-518: The two nations have gone to war four times: in 1947 , 1965 , 1971 , and 1999 . Three of these wars were fought over the disputed territory of Kashmir , while the third, the 1971 war, followed from India's support for the independence of Bangladesh . In the late 1980s, the Indian military twice intervened abroad at the invitation of the host country: a peace-keeping operation in Sri Lanka between 1987 and 1990; and an armed intervention to prevent
20550-639: The union territories of Jammu and Kashmir , Puducherry and the National Capital Territory of Delhi , have elected legislatures and governments following the Westminster system of governance. The remaining five union territories are directly ruled by the central government through appointed administrators. In 1956, under the States Reorganisation Act , states were reorganised on a linguistic basis. There are over
20700-495: The western part of the Indo-Gangetic plain, now turned into rich agricultural land by irrigation, its features no longer visible. Among the Indian subcontinent's notable indigenous trees are the astringent Azadirachta indica , or neem , which is widely used in rural Indian herbal medicine , and the luxuriant Ficus religiosa , or peepul , which is displayed on the ancient seals of Mohenjo-daro , and under which
20850-433: The winter elevation of foraging efficiency described for cormorants by various researchers is due to capturing larger fish not due to capturing more fish. In some freshwater systems, the losses of fish due to overwintering great cormorants were estimated to be up to 80 kg per ha each year (e.g. Vltava River, Czech Republic ). This cormorant forages by diving and capturing its prey in its beak. The duration of its dives
21000-444: The world in nominal per capita income and 125th in per capita income adjusted for purchasing power parity (PPP)—the vast majority of Indians fall into the low-income group. Until 1991, all Indian governments followed protectionist policies that were influenced by socialist economics. Widespread state intervention and regulation largely walled the economy off from the outside world. An acute balance of payments crisis in 1991 forced
21150-437: The world's most populous democracy since the time of its independence in 1947. It is a pluralistic , multilingual and multi-ethnic society . India's nominal per capita income increased from US$ 64 annually in 1951 to US$ 2,601 in 2022, and its literacy rate from 16.6% to 74%. During the same time, its population grew from 361 million to almost 1.4 billion, and India became the most populous country in 2023. From being
