Cetaceans are aquatic mammals constituting the infraorder Cetacea. There are around 89 living species; the first is the Odontoceti, the toothed whales, which consist of around 70 species, including the dolphin, beluga whale, sperm whale, beaked whale. The second is the Mysticeti, the baleen whales, which have a filter-feeder system, consist of 15 species divided into 3 families, include the right whale, bowhead whale, pygmy right whale, gray whale; the ancient and extinct ancestors of modern whales lived 53 to 45 million years ago. They diverged from even-toed ungulates, they were amphibious, evolved in the shallow waters that separated India from Asia. Around 30 species adapted to a oceanic life. Baleen whales split from toothed whales around 34 million years ago; the smallest cetacean is Maui's dolphin, at 50 kg. Baleen whales have a tactile system in the short hairs around their mouth. Cetaceans have well-developed senses—their eyesight and hearing are adapted for both air and water, they have a layer of blubber, under the skin to maintain body heat in cold water.
Several species exhibit sexual dimorphism. Two external forelimbs are modified into flippers. Cetaceans have streamlined bodies: they can swim quickly, with the killer whale able to travel at 56 kilometres per hour in short bursts, the fin whale able to cruise at 48 kilometres per hour, dolphins able to make tight turns at high speeds, some species diving to great depths. Although cetaceans are widespread, most species prefer the colder waters of the Northern and Southern Hemispheres, they spend their lives in the water of rivers. This has drastically affected their anatomy to be able to do so, they feed on fish and marine invertebrates. Some baleen whales are specialised for feeding on benthic creatures. Male cetaceans mate with more than one female, although the degree of polygyny varies with the species. Cetaceans are not known to have pair bonds. Male cetacean strategies for reproductive success vary between herding females, defending potential mates from other males, or whale song which attracts mates.
Calves are born in the fall and winter months, females bear all the responsibility for raising them. Mothers of some species fast and nurse their young for a short period of time, more typical of baleen whales as their main food source aren't found in their breeding and calving grounds. Cetaceans produce a number of vocalizations, notably the clicks and whistles of dolphins and the moaning songs of the humpback whale; the meat and oil of cetaceans have traditionally been used by indigenous peoples of the Arctic. Cetaceans have been depicted in various cultures worldwide. Dolphins are kept in captivity and are sometimes trained to perform tricks and tasks, other cetaceans aren't as kept in captivity. Cetaceans have been relentlessly hunted by commercial industries for their products, although this is now forbidden by international law; the baiji has become "Possibly Extinct" in the past century, while the vaquita and Yangtze finless porpoise are ranked Critically Endangered by the International Union for Conservation of Nature.
Besides hunting, cetaceans face threats from accidental trapping, marine pollution, ongoing climate change. The two parvorders, baleen whales and toothed whales, are thought to have diverged around thirty-four million years ago. Baleen whales have bristles made of keratin instead of teeth; the bristles filter other small invertebrates from seawater. Grey whales feed on bottom-dwelling mollusks. Rorqual family use throat pleats to expand their mouths to sieve out the water. Balaenids have massive heads. Most mysticetes prefer the food-rich colder waters of the Northern and Southern Hemispheres, migrating to the Equator to give birth. During this process, they are capable of relying on their fat reserves; the parvorder of Odontocetes – the toothed whales – include sperm whales, beaked whales, killer whales and porpoises. The teeth are designed for catching fish, squid or other marine invertebrates, not for chewing them, so prey is swallowed whole. Teeth are shaped like cones, pegs, tusks or variable.
Female beaked whales' teeth are hidden in the gums and are not visible, most male beaked whales have only two short tusks. Narwhals have vestigial teeth other than their tusk, present on males and 15% of females and has millions of nerves to sense water temperature and salinity. A few toothed whales, such as some killer whales, feed on mammals, such as pinnipeds and other whales. Toothed whales have well-developed senses – their eyesight and hearing are adapted for both air and water, they have advan
Gothenburg is the second-largest city in Sweden, fifth-largest in the Nordic countries, capital of the Västra Götaland County. It is situated by Kattegat, on the west coast of Sweden, has a population of 570,000 in the city center and about 1 million inhabitants in the metropolitan area. Gothenburg was founded as a fortified Dutch, trading colony, by royal charter in 1621 by King Gustavus Adolphus. In addition to the generous privileges given to his Dutch allies from the then-ongoing Thirty Years' War, the king attracted significant numbers of his German and Scottish allies to populate his only town on the western coast. At a key strategic location at the mouth of the Göta älv, where Scandinavia's largest drainage basin enters the sea, the Port of Gothenburg is now the largest port in the Nordic countries. Gothenburg is home to many students, as the city includes the University of Gothenburg and Chalmers University of Technology. Volvo was founded in Gothenburg in 1927; the original parent Volvo Group and the now separate Volvo Car Corporation are still headquartered on the island of Hisingen in the city.
Other key companies are Astra Zeneca. Gothenburg is served by Göteborg Landvetter Airport 30 km southeast of the city center; the smaller Göteborg City Airport, 15 km from the city center, was closed to regular airline traffic in 2015. The city hosts the Gothia Cup, the world's largest youth football tournament, alongside some of the largest annual events in Scandinavia; the Gothenburg Film Festival, held in January since 1979, is the leading Scandinavian film festival with over 155,000 visitors each year. In summer, a wide variety of music festivals are held in the city, including the popular Way Out West Festival; the city was named Göteborg in the city's charter in 1621 and given the German and English name Gothenburg. The Swedish name was given after the Göta älv, called Göta River in English, other cities ending in -borg. Both the Swedish and German/English names were in use before 1621 and had been used for the previous city founded in 1604 and burned down in 1611. Gothenburg is one of few Swedish cities to still have an official and used exonym.
Another example is the province of Scania in southern Sweden. The city council of 1641 consisted of four Swedish, three Dutch, three German, two Scottish members. In Dutch, Scots and German, all languages with a long history in this trade and maritime-oriented city, the name Gothenburg is or was used for the city. Variations of the official German/English name Gothenburg in the city's 1621 charter existed or exist in many languages; the French form of the city name is Gothembourg, but in French texts, the Swedish name Göteborg is more frequent. "Gothenburg" can be seen in some older English texts. In Spanish and Portuguese the city is called Gotemburgo; these traditional forms are sometimes replaced with the use of the Swedish Göteborg, for example by The Göteborg Opera and the Göteborg Ballet. However, Göteborgs universitet designated as the Göteborg University in English, changed its name to the University of Gothenburg in 2008; the Gothenburg municipality has reverted to the use of the English name in international contexts.
In 2009, the city council launched a new logotype for Gothenburg. Since the name "Göteborg" contains the Swedish letter "ö" the idea was to make the name more international and up to date by "turning" the "ö" sideways; as of 2015, the name is spelled "Go:teborg" on a large number of signs in the city. In the early modern period, the configuration of Sweden's borders made Gothenburg strategically critical as the only Swedish gateway to the North Sea and Atlantic, situated on the west coast in a narrow strip of Swedish territory between Danish Halland in the south and Norwegian Bohuslän in the north. After several failed attempts, Gothenburg was founded in 1621 by King Gustavus Adolphus; the site of the first church built in Gothenburg, subsequently destroyed by Danish invaders, is marked by a stone near the north end of the Älvsborg Bridge in the Färjenäs Park. The church was built in 1603 and destroyed in 1611; the city was influenced by the Dutch and Scots, Dutch planners and engineers were contracted to construct the city as they had the skills needed to drain and build in the marshy areas chosen for the city.
The town was designed like Dutch cities such as Amsterdam and New Amsterdam. The planning of the streets and canals of Gothenburg resembled that of Jakarta, built by the Dutch around the same time; the Dutchmen won political power, it was not until 1652, when the last Dutch politician in the city's council died, that Swedes acquired political power over Gothenburg. During the Dutch period, the town followed Dutch town laws and Dutch was proposed as the official language in the town. Robust city walls were built during the 17th century. In 1807, a decision was made to tear down most of the city's wall; the work started in 1810, was carried out by 150 soldiers from the Bohus regiment. Along with the Dutch, the town was influenced by Scots who settled down in Gothenburg. Many became people of high-profile. William Chalmers, the son of a Scottish immigrant, donated his fortunes to set up what became the Chalmers University of Technology. In 1841, the Scotsman Alexander Keiller founded the Götaverken shipbuilding company, in business until 1989.
His son James Keiller donated Keiller Park to the city in 1906. The Gothenburg coat of arms was based on the lion of the coat of arms of Sweden, symbolically holding a shield w

Zoology is the branch of biology that studies the animal kingdom, including the structure, evolution, classification and distribution of all animals, both living and extinct, how they interact with their ecosystems. The term is derived from Ancient Greek ζῷον, zōion, i.e. "animal" and λόγος, logos, i.e. "knowledge, study". The history of zoology traces the study of the animal kingdom from ancient to modern times. Although the concept of zoology as a single coherent field arose much the zoological sciences emerged from natural history reaching back to the biological works of Aristotle and Galen in the ancient Greco-Roman world; this ancient work was further developed in the Middle Ages by Muslim physicians and scholars such as Albertus Magnus. During the Renaissance and early modern period, zoological thought was revolutionized in Europe by a renewed interest in empiricism and the discovery of many novel organisms. Prominent in this movement were Vesalius and William Harvey, who used experimentation and careful observation in physiology, naturalists such as Carl Linnaeus, Jean-Baptiste Lamarck, Buffon who began to classify the diversity of life and the fossil record, as well as the development and behavior of organisms.
Microscopy revealed the unknown world of microorganisms, laying the groundwork for cell theory. The growing importance of natural theology a response to the rise of mechanical philosophy, encouraged the growth of natural history. Over the 18th, 19th, 20th centuries, zoology became an professional scientific discipline. Explorer-naturalists such as Alexander von Humboldt investigated the interaction between organisms and their environment, the ways this relationship depends on geography, laying the foundations for biogeography and ethology. Naturalists began to reject essentialism and consider the importance of extinction and the mutability of species. Cell theory provided a new perspective on the fundamental basis of life; these developments, as well as the results from embryology and paleontology, were synthesized in Charles Darwin's theory of evolution by natural selection. In 1859, Darwin placed the theory of organic evolution on a new footing, by his discovery of a process by which organic evolution can occur, provided observational evidence that it had done so.
Darwin gave a new direction to morphology and physiology, by uniting them in a common biological theory: the theory of organic evolution. The result was a reconstruction of the classification of animals upon a genealogical basis, fresh investigation of the development of animals, early attempts to determine their genetic relationships; the end of the 19th century saw the fall of spontaneous generation and the rise of the germ theory of disease, though the mechanism of inheritance remained a mystery. In the early 20th century, the rediscovery of Mendel's work led to the rapid development of genetics, by the 1930s the combination of population genetics and natural selection in the modern synthesis created evolutionary biology. Cell biology studies the structural and physiological properties of cells, including their behavior and environment; this is done on both the microscopic and molecular levels, for single-celled organisms such as bacteria as well as the specialized cells in multicellular organisms such as humans.
Understanding the structure and function of cells is fundamental to all of the biological sciences. The similarities and differences between cell types are relevant to molecular biology. Anatomy considers the forms of macroscopic structures such as organs and organ systems, it focuses on how organs and organ systems work together in the bodies of humans and animals, in addition to how they work independently. Anatomy and cell biology are two studies that are related, can be categorized under "structural" studies. Physiology studies the mechanical and biochemical processes of living organisms by attempting to understand how all of the structures function as a whole; the theme of "structure to function" is central to biology. Physiological studies have traditionally been divided into plant physiology and animal physiology, but some principles of physiology are universal, no matter what particular organism is being studied. For example, what is learned about the physiology of yeast cells can apply to human cells.
The field of animal physiology extends the tools and methods of human physiology to non-human species. Physiology studies how for example nervous, endocrine and circulatory systems and interact. Evolutionary research is concerned with the origin and descent of species, as well as their change over time, includes scientists from many taxonomically oriented disciplines. For example, it involves scientists who have special training in particular organisms such as mammalogy, herpetology, or entomology, but use those organisms as systems to answer general questions about evolution. Evolutionary biology is based on paleontology, which uses the fossil record to answer questions about the mode and tempo of evolution, on the developments in areas such as population genetics and evolutionary theory. Following the development of DNA fingerprinting techniques in the late 20th century, the application of these techniques in zoology has increased the understanding of animal populations. In the 1980s, developmental biology re-entered evolutionary biology from its initial exclusion from the modern synthesis through the study of evolutionary developmental biology.
Related fields considered part of evolutionary biology are phylogenetics and taxonomy. Scientific classification in zoology, is a method by which
Entomology is the scientific study of insects, a branch of zoology. In the past the term "insect" was more vague, the definition of entomology included the study of terrestrial animals in other arthropod groups or other phyla, such as arachnids, earthworms, land snails, slugs; this wider meaning may still be encountered in informal use. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, biomechanics, systematics, developmental biology, ecology and paleontology. At some 1.3 million described species, insects account for more than two-thirds of all known organisms, date back some 400 million years, have many kinds of interactions with humans and other forms of life on earth. Entomology is rooted in nearly all human cultures from prehistoric times in the context of agriculture, but scientific study began only as as the 16th century. William Kirby is considered as the father of Entomology.
In collaboration with William Spence, he published a definitive entomological encyclopedia, Introduction to Entomology, regarded as the subject's foundational text. He helped to found the Royal Entomological Society in London in 1833, one of the earliest such societies in the world. Entomology developed in the 19th and 20th centuries, was studied by large numbers of people, including such notable figures as Charles Darwin, Jean-Henri Fabre, Vladimir Nabokov, Karl von Frisch, two-time Pulitzer Prize winner E. O. Wilson. There has been a history of people becoming entomologists through museum curation and research assistance, such as Sophie Lutterlough at the Smithsonian National Museum of Natural History. Insect identification is an common hobby, with butterflies and dragonflies being the most popular. Most insects can be recognized to order such as Hymenoptera or Coleoptera. However, insects other than Lepidoptera are identifiable to genus or species only through the use of Identification keys and Monographs.
Because the class Insecta contains a large number of species and the characteristics separating them are unfamiliar, subtle, this is very difficult for a specialist. This has led to the development of automated species identification systems targeted on insects, for example, Daisy, ABIS, SPIDA and Draw-wing. In 1994, the Entomological Society of America launched a new professional certification program for the pest control industry called the Associate Certified Entomologist. To qualify as a "true entomologist" an individual would require an advanced degree, with most entomologists pursuing a PhD. While not true entomologists in the traditional sense, individuals who attain the ACE certification may be referred to as ACEs or Associate Certified Entomologists. Many entomologists specialize in a single order or a family of insects, a number of these subspecialties are given their own informal names derived from the scientific name of the group: Coleopterology – beetles Dipterology – flies Odonatology – dragonflies and damselflies Hemipterology – true bugs Isopterology – termites Lepidopterology – moths and butterflies Melittology – bees Myrmecology – ants Orthopterology – grasshoppers, etc.
Trichopterology – caddis flies Vespology – Social wasps Like other scientific specialties, entomologists have a number of local and international organizations. There are many organizations specializing in specific subareas.

Virtual International Authority File
The Virtual International Authority File is an international authority file. It is a joint project of several national libraries and operated by the Online Computer Library Center. Discussion about having a common international authority started in the late 1990s. After a series of failed attempts to come up with a unique common authority file, the new idea was to link existing national authorities; this would present all the benefits of a common file without requiring a large investment of time and expense in the process. The project was initiated by the US Library of Congress, the German National Library and the OCLC on August 6, 2003; the Bibliothèque nationale de France joined the project on October 5, 2007. The project transitioned to being a service of the OCLC on April 4, 2012; the aim is to link the national authority files to a single virtual authority file. In this file, identical records from the different data sets are linked together. A VIAF record receives a standard data number, contains the primary "see" and "see also" records from the original records, refers to the original authority records.
The data are available for research and data exchange and sharing. Reciprocal updating uses the Open Archives Initiative Protocol for Metadata Harvesting protocol; the file numbers are being added to Wikipedia biographical articles and are incorporated into Wikidata. VIAF's clustering algorithm is run every month; as more data are added from participating libraries, clusters of authority records may coalesce or split, leading to some fluctuation in the VIAF identifier of certain authority records.

Sweden the Kingdom of Sweden, is a Scandinavian Nordic country in Northern Europe. It borders Norway to the west and north and Finland to the east, is connected to Denmark in the southwest by a bridge-tunnel across the Öresund, a strait at the Swedish-Danish border. At 450,295 square kilometres, Sweden is the largest country in Northern Europe, the third-largest country in the European Union and the fifth largest country in Europe by area. Sweden has a total population of 10.2 million. It has a low population density of 22 inhabitants per square kilometre; the highest concentration is in the southern half of the country. Germanic peoples have inhabited Sweden since prehistoric times, emerging into history as the Geats and Swedes and constituting the sea peoples known as the Norsemen. Southern Sweden is predominantly agricultural, while the north is forested. Sweden is part of the geographical area of Fennoscandia; the climate is in general mild for its northerly latitude due to significant maritime influence, that in spite of this still retains warm continental summers.
Today, the sovereign state of Sweden is a constitutional monarchy and parliamentary democracy, with a monarch as head of state, like its neighbour Norway. The capital city is Stockholm, the most populous city in the country. Legislative power is vested in the 349-member unicameral Riksdag. Executive power is exercised by the government chaired by the prime minister. Sweden is a unitary state divided into 21 counties and 290 municipalities. An independent Swedish state emerged during the early 12th century. After the Black Death in the middle of the 14th century killed about a third of the Scandinavian population, the Hanseatic League threatened Scandinavia's culture and languages; this led to the forming of the Scandinavian Kalmar Union in 1397, which Sweden left in 1523. When Sweden became involved in the Thirty Years War on the Reformist side, an expansion of its territories began and the Swedish Empire was formed; this became one of the great powers of Europe until the early 18th century. Swedish territories outside the Scandinavian Peninsula were lost during the 18th and 19th centuries, ending with the annexation of present-day Finland by Russia in 1809.
The last war in which Sweden was directly involved was in 1814, when Norway was militarily forced into personal union. Since Sweden has been at peace, maintaining an official policy of neutrality in foreign affairs; the union with Norway was peacefully dissolved in 1905. Sweden was formally neutral through both world wars and the Cold War, albeit Sweden has since 2009 moved towards cooperation with NATO. After the end of the Cold War, Sweden joined the European Union on 1 January 1995, but declined NATO membership, as well as Eurozone membership following a referendum, it is a member of the United Nations, the Nordic Council, the Council of Europe, the World Trade Organization and the Organisation for Economic Co-operation and Development. Sweden maintains a Nordic social welfare system that provides universal health care and tertiary education for its citizens, it has the world's eleventh-highest per capita income and ranks in numerous metrics of national performance, including quality of life, education, protection of civil liberties, economic competitiveness, equality and human development.
The name Sweden was loaned from Dutch in the 17th century to refer to Sweden as an emerging great power. Before Sweden's imperial expansion, Early Modern English used Swedeland. Sweden is derived through back-formation from Old English Swēoþēod, which meant "people of the Swedes"; this word is derived from Sweon/Sweonas. The Swedish name Sverige means "realm of the Swedes", excluding the Geats in Götaland. Variations of the name Sweden are used in most languages, with the exception of Danish and Norwegian using Sverige, Faroese Svøríki, Icelandic Svíþjóð, the more notable exception of some Finnic languages where Ruotsi and Rootsi are used, names considered as referring to the people from the coastal areas of Roslagen, who were known as the Rus', through them etymologically related to the English name for Russia; the etymology of Swedes, thus Sweden, is not agreed upon but may derive from Proto-Germanic Swihoniz meaning "one's own", referring to one's own Germanic tribe. Sweden's prehistory begins in the Allerød oscillation, a warm period around 12,000 BC, with Late Palaeolithic reindeer-hunting camps of the Bromme culture at the edge of the ice in what is now the country's southernmost province, Scania.
This period was characterised by small bands of hunter-gatherer-fishers using flint technology. Sweden is first described in a written source in Germania by Tacitus in 98 AD. In Germania 44 and 45 he mentions the Swedes as a powerful tribe with ships that had a prow at each end. Which kings ruled these Suiones is unknown, but Norse mythology presents a long line of legendary and semi-legendary kings going back to the last centuries BC; as for literacy in Sweden itself, the runic script was in use among the south Scandinavian elite by at least the 2nd century AD, but all that has come down to the present from the Roman Period is curt inscriptions on artefacts of male names, demonstrating th
