A gill (/ɡɪl/ (listen)) is a respiratory organ found in many aquatic organisms that extracts dissolved oxygen from water and excretes carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (pl. branchiae) is the zoologists' name for gills (from Ancient Greek).
With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill chambers in which they store water, enabling them to use the dissolved oxygen when they are on land.
Galen observed that fish had multitudes of openings (foramina), big enough to admit gases, but too fine to give passage to water. Pliny the Elder held that fish respired by their gills, but observed that Aristotle was of another opinion. The word branchia comes from the Greek βράγχια, "gills", plural of βράγχιον (in singular, meaning a fin).
Many microscopic aquatic animals, and some larger but inactive ones, can absorb sufficient oxygen through the entire surface of their bodies, and so can respire adequately without gills. However, more complex or more active aquatic organisms usually require a gill or gills. Many invertebrates, and even amphibians, use both the body surface and gills for gaseous exchange.
Gills usually consist of thin filaments of tissue, lamellaee (plates), branches, or slender, tufted processes that have a highly folded surface to increase surface area. The delicate nature of the gills is possible because the surrounding water provides support. The blood or other body fluid must be in intimate contact with the respiratory surface for ease of diffusion.
A high surface area is crucial to the gas exchange of aquatic organisms, as water contains only a small fraction of the dissolved oxygen that air does. A cubic meter of air contains about 250 grams of oxygen at STP. The concentration of oxygen in water is lower than in air and it diffuses more slowly. In fresh water, the dissolved oxygen content is approximately 8 cm3/L compared to that of air which is 210 cm3/L. Water is 777 times more dense than air and is 100 times more viscous. Oxygen has a diffusion rate in air 10,000 times greater than in water. The use of sac-like lungs to remove oxygen from water would not be efficient enough to sustain life. Rather than using lungs, "[g]aseous exchange takes place across the surface of highly vascularised gills over which a one-way current of water is kept flowing by a specialised pumping mechanism. The density of the water prevents the gills from collapsing and lying on top of each other, which is what happens when a fish is taken out of water."
Usually water is moved across the gills in one direction by the current, by the motion of the animal through the water, by the beating of cilia or other appendages, or by means of a pumping mechanism. In fish and some molluscs, the efficiency of the gills is greatly enhanced by a countercurrent exchange mechanism in which the water passes over the gills in the opposite direction to the flow of blood through them. This mechanism is very efficient and as much as 90% of the dissolved oxygen in the water may be recovered.
The gills of vertebrates typically develop in the walls of the pharynx, along a series of gill slits opening to the exterior. Most species employ a countercurrent exchange system to enhance the diffusion of substances in and out of the gill, with blood and water flowing in opposite directions to each other. The gills are composed of comb-like filaments, the gill lamellae, which help increase their surface area for oxygen exchange.
When a fish breathes, it draws in a mouthful of water at regular intervals. Then it draws the sides of its throat together, forcing the water through the gill openings, so it passes over the gills to the outside. Fish gill slits may be the evolutionary ancestors of the tonsils, thymus glands, and Eustachian tubes, as well as many other structures derived from the embryonic branchial pouches.
The gills of fish form a number of slits connecting the pharynx to the outside of the animal on either side of the fish behind the head. Originally there were many slits, but during evolution, the number reduced, and modern fish mostly have five pairs, and never more than eight.
Sharks and rays typically have five pairs of gill slits that open directly to the outside of the body, though some more primitive sharks have six pairs and the Broadnose sevengill shark being the only cartilaginous fish exceeding this number. Adjacent slits are separated by a cartilaginous gill arch from which projects a cartilaginous gill ray. This gill ray is the support for the sheet-like interbranchial septum, which the individual lamellae of the gills lie on either side of. The base of the arch may also support gill rakers, projections into the pharyngeal cavity that help to prevent large pieces of debris from damaging the delicate gills.
A smaller opening, the spiracle, lies in the back of the first gill slit. This bears a small pseudobranch that resembles a gill in structure, but only receives blood already oxygenated by the true gills. The spiracle is thought to be homologous to the ear opening in higher vertebrates.
Most sharks rely on ram ventilation, forcing water into the mouth and over the gills by rapidly swimming forward. In slow-moving or bottom-dwelling species, especially among skates and rays, the spiracle may be enlarged, and the fish breathes by sucking water through this opening, instead of through the mouth.
Chimaeras differ from other cartilagenous fish, having lost both the spiracle and the fifth gill slit. The remaining slits are covered by an operculum, developed from the septum of the gill arch in front of the first gill.
In bony fish, the gills lie in a branchial chamber covered by a bony operculum. The great majority of bony fish species have five pairs of gills, although a few have lost some over the course of evolution. The operculum can be important in adjusting the pressure of water inside of the pharynx to allow proper ventilation of the gills, so bony fish do not have to rely on ram ventilation (and hence near constant motion) to breathe. Valves inside the mouth keep the water from escaping.
The gill arches of bony fish typically have no septum, so the gills alone project from the arch, supported by individual gill rays. Some species retain gill rakers. Though all but the most primitive bony fish lack spiracles, the pseudobranch associated with them often remains, being located at the base of the operculum. This is, however, often greatly reduced, consisting of a small mass of cells without any remaining gill-like structure.
Marine teleosts also use gills to excrete electrolytes. The gills' large surface area tends to create a problem for fish that seek to regulate the osmolarity of their internal fluids. Salt water is less dilute than these internal fluids, so saltwater fish lose large quantities of water osmotically through their gills. To regain the water, they drink large amounts of sea water and excrete the salt. Fresh water is more dilute than the internal fluids of fish, however, so freshwater fish gain water osmotically through their gills.
Lampreys and hagfish do not have gill slits as such. Instead, the gills are contained in spherical pouches, with a circular opening to the outside. Like the gill slits of higher fish, each pouch contains two gills. In some cases, the openings may be fused together, effectively forming an operculum. Lampreys have seven pairs of pouches, while hagfishes may have six to fourteen, depending on the species. In the hagfish, the pouches connect with the pharynx internally and a separate tube which has no respiratory tissue (the pharyngocutaneous duct) develops beneath the pharynx proper, expelling ingested debris by closing a valve at its anterior end. Lungfish larvae also have external gills, as does the primitive ray-finned fish Polypterus, though the latter has a structure different from amphibians.
Tadpoles of amphibians have from three to five gill slits that do not contain actual gills. Usually no spiracle or true operculum is present, though many species have operculum-like structures. Instead of internal gills, they develop three feathery external gills that grow from the outer surface of the gill arches. Sometimes, adults retain these, but they usually disappear at metamorphosis. Examples of salamanders that retain their external gills upon reaching adulthood are the olm and the mudpuppy.
Crustaceans, molluscs, and some aquatic insects have tufted gills or plate-like structures on the surfaces of their bodies. Gills of various types and designs, simple or more elaborate, have evolved independently in the past, even among the same class of animals. The segments of polychaete worms bear parapodia many of which carry gills. Sponges lack specialised respiratory structures, and the whole of the animal acts as a gill as water is drawn through its spongy structure.
Aquatic arthropods usually have gills which are in most cases modified appendages. In some crustaceans these are exposed directly to the water, while in others, they are protected inside a gill chamber. Horseshoe crabs have book gills which are external flaps, each with many thin leaf-like membranes.
Many marine invertebrates such as bivalve molluscs are filter feeders. A current of water is maintained through the gills for gas exchange, and food particles are filtered out at the same time. These may be trapped in mucus and moved to the mouth by the beating of cilia.
Respiration in the echinoderms (such as starfish and sea urchins) is carried out using a very primitive version of gills called papulae. These thin protuberances on the surface of the body contain diverticula of the water vascular system.
The gills of aquatic insects are tracheal, but the air tubes are sealed, commonly connected to thin external plates or tufted structures that allow diffusion. The oxygen in these tubes is renewed through the gills. In the larval dragon fly, the wall of the caudal end of the alimentary tract (rectum) is richly supplied with tracheae as a rectal gill, and water pumped into and out of the rectum provides oxygen to the closed tracheae.
A plastron is a type of structural adaptation occurring among some aquatic arthropods (primarily insects), a form of inorganic gill which holds a thin film of atmospheric oxygen in an area with small openings called spiracles that connect to the tracheal system. The plastron typically consists of dense patches of hydrophobic setae on the body, which prevent water entry into the spiracles, but may also involve scales or microscopic ridges projecting from the cuticle. The physical properties of the interface between the trapped air film and surrounding water allow gas exchange through the spiracles, almost as if the insect were in atmospheric air. Carbon dioxide diffuses into the surrounding water due to its high solubility, while oxygen diffuses into the film as the concentration within the film has been reduced by respiration, and nitrogen also diffuses out as its tension has been increased. Oxygen diffuses into the air film at a higher rate than nitrogen diffuses out. However, water surrounding the insect can become oxygen-depleted if there is no water movement, so many such insects in still water actively direct a flow of water over their bodies.
The inorganic gill mechanism allows aquatic insects with plastrons to remain constantly submerged. Examples include many beetles in the family Elmidae, aquatic weevils, and true bugs in the family Aphelocheiridae, as well as at least one species of ricinuleid arachnid. A somewhat similar mechanism is used by the diving bell spider, which maintains an underwater bubble that exchanges gas like a plastron. Other diving insects (such as backswimmers, and hydrophilid beetles) may carry trapped air bubbles, but deplete the oxygen more quickly, and thus need constant replenishment.
An agaric () is a type of mushroom fungus fruiting body characterized by the presence of a pileus (cap) that is clearly differentiated from the stipe (stalk), with lamellae (gills) on the underside of the pileus. "Agaric" can also refer to a basidiomycete species characterized by an agaric-type fruiting body. Archaically agaric meant 'tree-fungus' (after Latin agaricum); however, that changed with the Linnaean interpretation in 1753 when Linnaeus used the generic name Agaricus for gilled mushrooms.
Most species of agarics are within orders of and describe the members of the order Agaricales in the subphylum Agaricomycotina. The exceptions, where agarics have evolved independently, feature largely in the orders Russulales, Boletales, Hymenochaetales and several other groups of the overarching phylum Basidiomycetes. Old systems of classification place all agarics in the Agaricales and some (mostly older) sources use "agarics" as the colloquial collective noun for the Agaricales. Contemporary sources now tend to use the term euagarics to refer to all agaric members of the Agaricales. "Agaric" is also sometimes used as a common name for members of the genus Agaricus, as well as for members of other genera; for example, Amanita muscaria is sometimes called "fly agaric".Blizzard (comics)
Blizzard is the name of different fictional characters appearing in American comic books published by Marvel Comics. The character is usually depicted as a member of Iron Man's rogues gallery.Creature from the Black Lagoon
Creature from the Black Lagoon is a 1954 American black-and-white 3D monster horror film from Universal-International, produced by William Alland, directed by Jack Arnold, that stars Richard Carlson, Julia Adams, Richard Denning, Antonio Moreno and Whit Bissell. The Creature was played by Ben Chapman on land and by Ricou Browning underwater. The film premiered in Detroit on February 12 and was released on a regional basis, opening on various dates.
Creature from the Black Lagoon was filmed in 3D and originally projected by the polarized light method. The audience wore viewers with gray polarizing filters, similar to the viewers most commonly used today. Because the brief 1950s 3D film fad had peaked in mid-1953 and was fading fast in early 1954, many audiences actually saw the film "flat", in 2D. Typically, the film was shown in 3D in large downtown theaters and flat in smaller neighborhood theaters. In 1975 Creature from the Black Lagoon was re-released to theaters in the inferior red-and-blue-glasses anaglyph 3D format, which was also used for a 1980 home video release on Beta and VHS videocassettes.For marketing reasons, a comedic appearance with Abbott and Costello on an episode of The Colgate Comedy Hour aired prior to the film's release. The appearance is commonly known as Abbott and Costello Meet the Creature from the Black Lagoon. Ben Chapman reprised his role as the Gill-Man for the program.Creature from the Black Lagoon generated two sequels: Revenge of the Creature (1955), which was also filmed and released in 3D in hopes of reviving the format, and The Creature Walks Among Us (1956), filmed in 2D. The creature, also known as the Gill-man, is usually counted among the classic Universal Monsters.Eric Gill
Arthur Eric Rowton Gill (; 22 February 1882 – 17 November 1940) was an English sculptor, typeface designer, and printmaker, who was associated with the Arts and Crafts movement. He is a controversial figure, with his well-known religious views and subject matter generally viewed as being at odds with his sexual behaviour, including his erotic art and sexual abuse of his daughters and his sisters.
Gill was named Royal Designer for Industry, the highest British award for designers, by the Royal Society of Arts. He also became a founder-member of the newly established Faculty of Royal Designers for Industry.Frank Gill (ornithologist)
Frank Bennington Gill (October 2, 1941 in New York City) is an American ornithologist with worldwide research interests and birding experience. He is perhaps best known as the author of the textbook Ornithology (3rd edition, 2006), the leading textbook in the field.
Gill was raised in Teaneck, New Jersey. He reported that he became interested in birds at the age of seven, when his grandfather, Frank Rockingham Downing, showed him a song sparrow at a birdbath. This was the first time he had seen a bird through binoculars, "and I was hooked."After Gill received his PhD in zoology from the University of Michigan in 1969 (where he had also completed his undergraduate degree), he joined the ornithology department at the Academy of Natural Sciences in Philadelphia. From 1969-1995, Gill was a full-time staff member of the academy, where he held various positions throughout his tenure, including that of chairman for the Department of Ornithology and vice president for systematics and evolutionary biology. During his time at the academy, Gill was instrumental in reestablishing the academy's position as one of the leading centers of American ornithological research. This was manifested through Gill's work as the founding director of the VIREO program (Visual Resources for Ornithology) and his work as the editor of the encyclopedic series Birds of North America, Life Histories for the 21st Century. In 1988 he was awarded the Linnaean Society of New York's Eisenmann Medal. Since 1996, Gill has been affiliated with the academy as a research fellow.
More recently, Gill was the president of the American Ornithologists' Union from 1998-2000. Besides his acclaimed textbook, Gill’s published works include over 150 scientific and popular articles. His worldwide research programs included field studies of island birds, hybridization by blue-winged and golden-winged warblers, flower-feeding strategies of sunbirds of Africa and of hermit hummingbirds of Middle America, and phylogeny through DNA of the chickadees of the world. For his contributions to ornithology, Gill was recognized with the William Brewster Award, the highest honor bestowed by the AOU. Additionally, Gill is an elected member of the International Ornithological Congress, as well as the co-author, with Minturn Wright, of Birds of the World: Recommended English Names (2006). Since 1994 he has led the international effort to use a consistent set of unique English names and authoritative species taxonomy of the birds of the world.Gill’s contributions include innovative program leadership combined with a personal commitment to engaging the public in ornithology through citizen science. He pioneered “cyberbirding”—the use of the internet for nationwide citizen science initiatives—including the conversion of classic Christmas Bird Count to modern technology. Frank and his colleagues at the Cornell Lab of Ornithology also were awarded US Patent No. 6,772,142 for their internet software application to translate online georeference data to an interactive database. With such tools, he and his colleagues created the Great Backyard Bird Count and then the eBird initiative of Audubon and the Cornell Lab of Ornithology.
In 1996, Gill became senior vice president and director of science for the National Audubon Society, a position from which he retired in 2004. At Audubon, he championed the nationwide Important Bird Areas initiative in partnership with BirdLife International. In 2007, he was elected to the Board of Directors of the National Audubon Society and served as interim president and CEO (2010). He has been quoted in a number of news reports concerning birds.Gill (Martian crater)
Gill Crater is an impact crater in the Arabia quadrangle of Mars, located at 15.9°N latitude and 354.6°W longitude. It is 83.0 km in diameter and was named after David Gill (astronomer), and the name was approved in 1973 by the International Astronomical Union (IAU) Working Group for Planetary System Nomenclature (WGPSN).Gill Hill
Gill Hill is a mountain in the Central New York region of New York. It is located southeast of Ketchum Corners, New York.Gill raker
Gill rakers in fish are bony or cartilaginous processes that project from the branchial arch (gill arch) and are involved with suspension feeding tiny prey. They are not to be confused with the gill filaments that compose the fleshy part of the gill used for gas exchange. Rakers are usually present in two rows, projecting from both the anterior and posterior side of each gill arch. Rakers are widely varied in number, spacing, and form. By preventing food particles from exiting the spaces between the gill arches, they enable the retention of food particles in filter feeders.The structure and spacing of gill rakers in fish determines the size of food particles trapped, and correlates with feeding behavior. Fish with densely spaced, elongated, comb-like gill rakers are efficient at filtering tiny prey, whereas carnivores and omnivores often have more widely spaced gill rakers with secondary projections. Because gill raker characters often vary between closely related taxa, they are commonly used in the classification and identification of fish species. Much of the variation in gill raker morphology is thought to be due to adaptation to optimize the consumption of different diets.
To prevent the potentially damaging passage of solid material through the gill slits and over the gill filaments, early gill rakers strained large particles from the water and diverted them to the esophagus. Since an appreciable fraction of this material was nutritious, rakers subsequently evolved as food-trapping mechanisms in filter feeders. Gill rakers, when long and closely set, play the same role in suspension-feeding fish such as mullet, herring, megamouth, basking and whale sharks, as baleen in the filter-feeding whales.Gill slit
Gill slits are individual openings to gills, i.e., multiple gill arches, which lack a single outer cover. Such gills are characteristic of cartilaginous fish such as sharks, and rays, as well as primitive fish such as lampreys. In contrast, bony fishes have a single outer bony gill covering called an operculum.
Most sharks and rays have five pairs of gill slits, but a few species have 6 or 7 pairs. Shark gill slits lie in a row behind the head. The anterior edge of a gill slit is motile, moving outward to allow water to exit, but closing to prevent reverse flow. A modified slit, called a spiracle, lies just behind the eye, which assists the shark with taking in water during respiration and plays a major role in bottom–dwelling sharks. Spiracles are reduced or missing in active pelagic sharks. While the shark is moving, water passes through the mouth and over the gills in a process known as "ram ventilation". While at rest, most sharks pump water over their gills to ensure a constant supply of oxygenated water. A small number of species have lost the ability to pump water through their gills and must swim without rest. These species are obligate ram ventilators and would presumably asphyxiate if unable to move. Obligate ram ventilation is also true of some pelagic bony fish species.The true gill slits in embryonic fish develop into fish gills. However, the slits in tetrapods do not, so a more general name for the vertebral structures is pharyngeal slits. Gill slits likely originated from pharyngeal slits in tunicates that were used for filter-feeding. The term "gill slits" has also been used to refer to the folds of skin in the pharyngeal region in embryos. It is now accepted that it is the vertebrate pharyngeal pouches and not the neck slits that are homologous to the pharyngeal slits of invertebrate chordates.Gillnetting
Gillnetting is a common fishing method used by commercial and artisanal fishers of all the oceans and in some freshwater and estuary areas. Gill nets are composed of vertical panels of netting that hang from a line with regularly spaced floaters that hold the line on the surface of the water. The floats are sometimes called "corks" and the line with corks is generally referred to as a "cork line." The line along the bottom of the panels is generally weighted. Traditionally this line has been weighted with lead and may be referred to as "lead line." A gill net is normally set in a straight line. Gill nets can be characterized by mesh size, as well as colour and type of filament from which they are made. Fish may be caught by gill nets in three ways:
Wedged – held by the mesh around the body.
Gilled – held by mesh slipping behind the opercula.
Tangled – held by teeth, spines, maxillaries, or other protrusions without the body penetrating the mesh.Most often fish are gilled. A fish swims into a net and passes only part way through the mesh. When it struggles to free itself, the twine slips behind the gill cover and prevents escape.Gillnets are so effective that their use is closely monitored and regulated by fisheries management and enforcement agencies. Mesh size, twine strength, as well as net length and depth are all closely regulated to reduce bycatch of non-target species. Gillnets have a high degree of size selectivity. Most salmon fisheries in particular have an extremely low incidence of catching non-target species.
A fishing vessel rigged to fish by gillnetting is a gillnetter. A gillnetter which deploys its gillnet from the bow is a bowpicker, while one which deploys its gillnet from the stern is a sternpicker.JLS
JLS (an initialism of Jack the Lad Swing) were an English pop/R&B group, which consisted of members Aston Merrygold, Oritsé Williams, Marvin Humes, and JB Gill, originally formed by Williams. They initially signed to Tracklacers production company New Track City and then went on to become runners-up of the fifth series of the ITV reality talent show The X Factor in 2008, coming second to Alexandra Burke.
Following their appearance on The X Factor, JLS signed to Epic Records. Their first two singles "Beat Again" and "Everybody in Love" both went to number one on the UK Singles Chart.The band's self-titled debut album was released on 9 November 2009, and has since sold over 1 million copies in the UK. JLS won the awards for British Breakthrough and British Single ("Beat Again") at the 2010 BRIT Awards. They also won several awards at the MOBO Awards for Best song for "Beat Again" in 2009 and also Best Newcomer in the same year. In 2010 they won the MOBO Awards for Best UK act and Best Album. They also went on to win their fifth MOBO in 2012 by winning Best Video for "Do You Feel What I Feel?". They won the title of the UK's hardest-working band for two consecutive years, in 2011 and 2012.In 2010, JLS signed a record deal with the US record label Jive Records, and released "Everybody in Love" as their debut US single, but it failed to chart. "The Club Is Alive", the lead single from their second studio album, was released in the UK in July 2010, and earned the band their third number-one on the UK Singles Chart. Their single "Love You More", was the official single for Children in Need in 2010, and gave the group their fourth number-one single in the UK. Their single "She Makes Me Wanna" featuring Dev was their fifth UK number one. As of 2012, their debut album and single has been named one of The X Factor's top ten biggest-selling debut singles and albums. As of 2013, they are the 16th-richest reality TV stars in the UK, with an estimated fortune of £6 million per member, thus giving the band a financial worth of approximately £24 million.JLS have sold over 6 million records in the UK alone and more than 10 million records worldwide. The group later split up in 2013.Jamie Vardy
Jamie Richard Vardy (né Gill; born 11 January 1987) is an English professional footballer who plays as a striker for Premier League club Leicester City and the England national team.
After being released by Sheffield Wednesday at the age of sixteen, Vardy began his senior career with Stocksbridge Park Steels, breaking into the first team in 2007 and spending three seasons before joining Northern Premier League club F.C. Halifax Town in 2010. Scoring 25 goals in his debut season, he won the club's "Player's Player of the Year" award, then moved to Conference Premier club Fleetwood Town in August 2011 for an undisclosed fee. He scored 31 league goals in his first season at his new team, winning the team's "Player of the Year" award as they won the division.
In May 2012, Vardy signed for Leicester City in the Championship for a non-League record transfer fee of £1 million, and helped the team win the Championship in 2014. In the 2015–16 Premier League season, he scored in eleven consecutive Premier League matches, breaking Ruud van Nistelrooy's record, and was voted the Premier League Player of the Season and FWA Footballer of the Year as outsiders Leicester won the title. Vardy made his international debut in June 2015 and was selected for UEFA Euro 2016 and the 2018 FIFA World Cup.Johnny Gill
Johnny Gill Jr. (born May 22, 1966), also known as J.G., J. Skillz and Johnny G, is an American singer-songwriter and actor. Gill is the sixth and final member of the R&B/pop group New Edition, and was also a member of the supergroup called LSG, with Gerald Levert and Keith Sweat. He is currently in the new group Heads of State with New Edition members Bobby Brown and Ralph Tresvant.Lamella (mycology)
A lamella, or gill, is a papery hymenophore rib under the cap of some mushroom species, most often but not always agarics. The gills are used by the mushrooms as a means of spore dispersal, and are important for species identification. The attachment of the gills to the stem is classified based on the shape of the gills when viewed from the side, while color, crowding and the shape of individual gills can also be important features. Additionally, gills can have distinctive microscopic or macroscopic features. For instance, Lactarius species typically seep latex from their gills.
It was originally believed that all gilled fungi were Agaricales, but as fungi were studied in more detail, some gilled species were demonstrated not to be. It is now clear that this is a case of convergent evolution (i.e. gill-like structures evolved separately) rather than being an anatomic feature that evolved only once. The apparent reason that various basidiomycetes have evolved gills is that it is the most effective means of increasing the ratio of surface area to mass, which increases the potential for spore production and dispersal.
Other groups of fungi to bear gills include:
The genera Russula and Lactarius of the Russulales.
Several genera in the Boletales, including Gomphidius and Chroogomphus as well as Tapinella atrotomentosa (which has been traditionally named Paxillus atrotomentosus) and other species in that genus, the False chanterelle (Hygrophoropsis aurantiaca).
Such polypore-like fungi such as Daedalea quercina, Daedaleopsis confragosa, Lenzites betulina and Gloeophyllum sepiarium.Members of the two related genera of chanterelles, Cantharellus and Craterellus, have rudimentary lamellar structures which are sometimes referred to as "false gills". They are distinguished from "true gills" because the structure of the fertile surface ("hymenium") continues uninterrupted over the gill edge, so they are little more than folds, wrinkles or veins. The genus Gomphus also has false gills. These primitive lamellae indicate how the evolution towards true gills probably happened.New Edition
New Edition is an American R&B group from the Roxbury neighborhood of Boston, Massachusetts, formed in 1978. The group reached its height of popularity in the 1980s. During the group's first experience with fame in 1983, its members were Ricky Bell, Michael Bivins, Bobby Brown, Ronnie DeVoe and Ralph Tresvant. Early hits included "Candy Girl," "Cool It Now," and "Mr. Telephone Man". Tresvant was the lead singer on most of the songs. Brown was voted out of the group in 1985 and embarked on a solo career. The group continued for a time with its remaining four members, but eventually recruited singer Johnny Gill, who would be introduced on their 1988 album Heart Break. The group went on hiatus in 1990, while its various members worked on side projects, such as the group Bell Biv DeVoe. Gill and Tresvant also recorded successful solo albums.
All six members of New Edition reunited in 1996 to record the group's sixth studio album Home Again. During the ill-fated Home Again Tour, both Bobby Brown and Michael Bivins quit the group, forcing the remainder of the tour to be canceled. Various reunions have occurred since, usually with the 1987-1990 lineup, though occasionally also including Brown. Their last studio album was 2004's One Love.
On May 3, 2011, New Edition issued a press release on their official website announcing that all six members were reuniting as New Edition to kick off the 30th anniversary celebration of Candy Girl with their fans. They received their star on the Hollywood Walk of Fame on January 23, 2017. On January 24, 2017, a three-part docuseries, The New Edition Story, premiered on BET about the group's career and personal life. It was later announced that all six members will reunite to record another album and go on tour.Slats Gill
Amory Tingle "Slats" Gill (May 1, 1901 – April 5, 1966) was an American college basketball coach, the head coach at Oregon State University in Corvallis for 36 seasons. As a player, Gill was twice named to the All-Pacific Coast Conference basketball team. As head coach, he amassed 599 victories with a winning percentage of .604. Gill was also the head coach of the baseball team for six seasons and later was the OSU athletic director.
Gill is a member of the Naismith Memorial Basketball Hall of Fame, the National Collegiate Basketball Hall of Fame, and the Oregon Sports Hall of Fame. He is also honored as the namesake of Gill Coliseum, opened in 1949, venue for basketball, wrestling, and gymnastics at OSU.Theodore Gill
Theodore Nicholas Gill (March 21, 1837 – September 25, 1914) was an American ichthyologist, mammalogist, malacologist and librarian.Trematoda
Trematoda is a class within the phylum Platyhelminthes. It includes two groups of parasitic flatworms, known as flukes.
They are internal parasites of molluscs and vertebrates. Most trematodes have a complex life cycle with at least two hosts. The primary host, where the flukes sexually reproduce, is a vertebrate. The intermediate host, in which asexual reproduction occurs, is usually a snail.Vince Gill
Vincent Grant Gill (born April 12, 1957) is an American country singer, songwriter and multi-instrumentalist. He has achieved commercial success and fame both as frontman to the country rock band Pure Prairie League in the 1970s and as a solo artist beginning in 1983, where his talents as a vocalist and musician have placed him in high demand as a guest vocalist and a duet partner.
