Bergall
The cunner (''Tautogolabrus adspersus''), also known as the blue perch, bergall, chogset, choggie, conner or sea perch, is a species of wrasse native to the northwestern Atlantic, where it is found from the Gulf of St. Lawrence and Newfoundland Newfoundland and Labrador (; french: Terre-Neuve-et-Labrador; frequently abbreviated as NL) is the easternmost province of Canada, in the country's Atlantic region. The province comprises the island of Newfoundland and the continental region ... to the Chesapeake Bay. They inhabit inshore waters living near the sea floor at depths from , preferring areas with beds of seaweed, shipwrecks, or wharf pilings. They spend the winter months in a state of torpor underneath rocks. They can also be found in the aquarium trade. Often, cunner is found mixed in with tautogs, living on or near the same structures. Much of the food eaten by those bergall living among blackfish are the leftovers from the blackfishes prey. They can be distin ...

Albert Günther
Albert Karl Ludwig Gotthilf Günther FRS, also Albert Charles Lewis Gotthilf Günther (3 October 1830 – 1 February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described. Early life and career Günther was born in Esslingen in Swabia (Württemberg). His father was a ''Stiftungs-Commissar'' in Esslingen and his mother was Eleonora Nagel. He initially schooled at the Stuttgart Gymnasium. His family wished him to train for the ministry of the Lutheran Church for which he moved to the University of Tübingen. A brother shifted from theology to medicine, and he, too, turned to science and medicine at Tübingen in 1852. His first work was "''Ueber den Puppenzustand eines Distoma''". He graduated in medicine with an M.D. from Tübingen in 1858, the same year in which he published a handbook of zoology for students of ...

Aquarium
An aquarium (plural: ''aquariums'' or ''aquaria'') is a vivarium of any size having at least one transparent side in which aquatic plants or animals are kept and displayed. Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles, such as turtles, and aquatic plants. The term ''aquarium'', coined by English naturalist Philip Henry Gosse, combines the Latin root , meaning 'water', with the suffix , meaning 'a place for relating to'. The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large. The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, ''The Aquarium: An Unveiling of the Wonders of the Deep Sea'' in 1854.Katherine C. Grier (2008) "Pet ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Hypoxia (environmental)
Hypoxia refers to low oxygen conditions. Normally, 20.9% of the gas in the atmosphere is oxygen. The partial pressure of oxygen in the atmosphere is 20.9% of the total barometric pressure. In water, oxygen levels are much lower, approximately 7 ppm or 0.0007% in good quality water, and fluctuate locally depending on the presence of photosynthetic organisms and relative distance to the surface (if there is more oxygen in the air, it will diffuse across the partial pressure gradient). Atmospheric hypoxia Atmospheric hypoxia occurs naturally at high altitudes. Total atmospheric pressure decreases as altitude increases, causing a lower partial pressure of oxygen, which is defined as hypobaric hypoxia. Oxygen remains at 20.9% of the total gas mixture, differing from hypoxic hypoxia, where the percentage of oxygen in the air (or blood) is decreased. This is common in the sealed burrows of some subterranean animals, such as blesmols. Atmospheric hypoxia is also the basis of altitude tra ...

Grouper
Groupers are fish of any of a number of genera in the subfamily Epinephelinae of the family Serranidae, in the order Perciformes. Not all serranids are called "groupers"; the family also includes the sea basses. The common name "grouper" is usually given to fish in one of two large genera: ''Epinephelus'' and ''Mycteroperca''. In addition, the species classified in the small genera ''Anyperidon'', ''Cromileptes'', ''Dermatolepis'', ''Graciela'', ''Saloptia'', and ''Triso'' are also called "groupers." Fish in the genus ''Plectropomus'' are referred to as "coral groupers." These genera are all classified in the subfamily Epiphelinae. However, some of the hamlets (genus ''Alphestes''), the hinds (genus ''Cephalopholis''), the lyretails (genus ''Variola''), and some other small genera (''Gonioplectrus'', ''Niphon'', ''Paranthias'') are also in this subfamily, and occasional species in other serranid genera have common names involving the word "grouper." Nonetheless, the word "grou ...

Rockfish
Rockfish is a common term for several species of fish, referring to their tendency to hide among rocks. The name rockfish is used for many kinds of fish used for food. This common name belongs to several groups that are not closely related, and can be arbitrary. Specific examples of fish termed rockfish include: *The family Sebastidae, marine fishes that inhabit oceans around the world. They may be included in the family Scorpaenidae. ** ''Sebastes'',Rockfish (''Sebastes'' spp.).
Monterey Bay Aquarium. a commercially important genus of fish in the Sebastidae inhabiting mainly the North Pacific, but with a few species in the North Atlantic and southern oceans * '''', a genus of fis ...

Black Sea Bass
The black sea bass (''Centropristis striata'') is a species of marine ray-finned fish, a sea bass from the subfamily Serraninae which is part of the family Serranidae, which also includes the groupers and anthias. It is found in the western Atlantic Ocean, where it is an important species for commercial and recreational fisheries. Description The black sea bass has an oblong, laterally compressed body. It has a large mouth, armed with bands of teeth on the jaw and with a triangular patch of teeth in the front part roof of the mouth and more teeth along the sides of that area, the mouth extending as far as below the middle of the eye. The preopercle has fine serrations on its margin and is evenly rounded, while the gill cover bears three flat spines. The dorsal fin has ten spines, the front spines being longer than the rearmost, and 11 soft rays. The membranes between the spines of the dorsal fin are deeply notched. The anal fin has three spines and seven soft rays. The caudal fi ...

Tautog
The tautog (''Tautoga onitis''), also known as the blackfish, is a species of wrasse native to the western Atlantic Ocean from Nova Scotia to South Carolina. This species inhabits hard substrate habitats in inshore waters at depths from . It is currently the only known member of its genus. Barlett (1848) wrote, " autaugis a Native American word, and may be found in Roger Williams' ''Key to the Indian Language''." The name is from the Narragansett language, originally ''tautauog'' (pl. of ''taut''). It is also called a "black porgy" (''cf.'' Japanese black porgy), "chub" (''cf.'' the freshwater chub), "oyster-fish" (in North Carolina) or "blackfish" (in New York/New Jersey, New England). Description Tautog are brown and dark olive, with white blotches, and have plump, elongated bodies. They have an average weight of and reach a maximum length and weight of and respectively. Tautog have many adaptations to life in and around rocky areas. They have thick, rubbery lips and p ...

Torpor
Torpor is a state of decreased physiological activity in an animal, usually marked by a reduced body temperature and metabolic rate. Torpor enables animals to survive periods of reduced food availability. The term "torpor" can refer to the time a hibernator spends at low body temperature, lasting days to weeks, or it can refer to a period of low body temperature and metabolism lasting less than 24 hours, as in "daily torpor". Animals that undergo daily torpor include birds (even tiny hummingbirds, notably Cypselomorphae) and some mammals, including many marsupial species, rodent species (such as mice), and bats. During the active part of their day, such animals maintain normal body temperature and activity levels, but their metabolic rate and body temperature drop during a portion of the day (usually night) to conserve energy. Some animals seasonally go into long periods of inactivity, with reduced body temperature and metabolism, made up of multiple bouts of torpor. This is kno ...

Johann Julius Walbaum
Johann Julius Walbaum (30 June 1724 – 21 August 1799) was a German physician, naturalist and fauna taxonomist. Works As an ichthyologist, he was the first to describe many previously unknown fish species from remote parts of the globe, such as the Great Barracuda (''Sphyraena barracuda''), the Chum salmon (''Oncorhynchus keta'') from the Kamchatka River in Siberia, and the curimatá-pacú (''Prochilodus marggravii'') from the São Francisco River in Brazil. He was also the first to observe gloves as a preventative against infection in medical surgery. In 1758, the gloves he observed were made from the cecum of the sheep, rather than rubber, which had not yet been discovered. Legacy The Natural History Museum in Lübeck, opened in 1893, was based on Walbaum's extensive scientific collection, which was lost during the Second World War World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945.
