Citharichthys Amblybregmatus
''Citharichthys amblybregmatus'' is a species of flatfish in the large-tooth flounder family Paralichthyidae. It is native to the western north Atlantic Ocean. It has been collected at a depth of . It is a demersal fish. Like the rest of the large-tooth flounders, it has both eyes on the left side of its head. The species was described at the same time as the anglefin whiff. Both species display sexual dimorphism, with the males displaying several secondary sex characteristics, making both species similar to the previously described horned whiff (''Citharichthys cornutus'').

Elmer Julius Gutherz
Elmer is a name of Germanic British origin. The given name originated as a surname, a medieval variant of the given name Aylmer, derived from Old English ''æþel'' (noble) and ''mær'' (famous). It was adopted as a given name in the United States, "in honor of the popularity of the brothers Ebenezer and Jonathan Elmer, leading supporters of the American Revolution." The name has declined in popularity since the first decades of the 20th century and fell out of the top 1,000 names used for American boys in 2009. However, it continues in use for newborn boys in the United States, where 154 boys born there in 2021 received the name. The name is common in the United States and Canada. Notable people with the name include: Mononym * Eilmer of Malmesbury (or Elmer), 11th-century English Benedictine monk * In the amateur radio subculture, an ''Elmer'' is a mentor to a newcoming amateur radio operatorThe term first appeared in the March, 1971 issue of ''QST'' magazine's "How's DX" ...

Flatfish
A flatfish is a member of the Ray-finned fish, ray-finned demersal fish order (biology), order Pleuronectiformes, also called the Heterosomata, sometimes classified as a suborder of Perciformes. In many species, both eyes lie on one side of the head, one or the other migrating through or around the head during development. Some species face their left sides upward, some face their right sides upward, and others face either side upward. Many important food fish are in this order, including the flounders, sole (fish), soles, turbot, plaice, and halibut. Some flatfish can camouflage themselves on the ocean floor. Taxonomy Over 800 described species are placed into 16 families. Broadly, the flatfishes are divided into two suborders, Psettodoidei and Pleuronectoidei, with > 99% of the species diversity found within the Pleuronectoidei. The largest families are Soleidae, Bothidae and Tonguefish, Cynoglossidae with more than 150 species each. There also exist two monotypic families (P ...

Paralichthyidae
Large-tooth flounders or sand flounders are a family, Paralichthyidae, of flounders. The family contains 14 genera with a total of about 110 species. They lie on the sea bed on their right side; both eyes are always on the left side of the head, while the Pleuronectidae usually (but not always) have their eyes on the right side of the head. They are found in temperate and tropical waters of the Atlantic, Indian and Pacific Oceans. Several species are important commercial and game fishes, notably the California halibut, ''Paralichthys californicus'' and the Pacific sanddab The Pacific sanddab (''Citharichthys sordidus'') is a species of flatfish. It is by far the most common sanddab, and it shares its habitat with the longfin sanddab (''C. xanthostigma'') and the speckled sanddab (''C. stigmaeus''). It is a mediu ..., ''Citharichthys sordidus''. Phylogenetic analyses have long indicated the non-monophyly of this family e.g., and two lineages have been consistently apparen ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Demersal Fish
Demersal fish, also known as groundfish, live and feed on or near the bottom of seas or lakes (the demersal zone).Walrond Carl . "Coastal fish - Fish of the open sea floor"Te Ara - the Encyclopedia of New Zealand. Updated 2 March 2009 They occupy the sea floors and lake beds, which usually consist of mud, sand, gravel or rocks. In coastal waters they are found on or near the continental shelf, and in deep waters they are found on or near the continental slope or along the continental rise. They are not generally found in the deepest waters, such as abyssal depths or on the abyssal plain, but they can be found around seamounts and islands. The word ''demersal'' comes from the Latin ''demergere'', which means ''to sink''. Demersal fish are bottom feeders. They can be contrasted with pelagic fish which live and feed away from the bottom in the open water column. Demersal fish fillets contain little fish oil (one to four percent), whereas pelagic fish can contain up to 30 percent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anglefin Whiff
''Citharichthys gymnorhinus'', the anglefin whiff, is a species of flatfish in the large-tooth flounder family Paralichthyidae. It is a demersal marine fish that inhabits the mid to outer continental shelf of the western Atlantic Ocean, in both tropical and subtropical waters. It ranges from the Bahamas and Florida in the north to Guyana and Nicaragua in the south, though larvae samples have also been collected off the coast of Canada. It occurs at depths between , but is most commonly found in shallower waters. Like the rest of the large-tooth flounders, it has both eyes on the left side of its head. It is one of the smallest members of its genus and one of the smallest flatfishes, growing to a maximum length of . As a result, it is of no commercial importance. It is similar in size and appearance to ''Citharichthys cornutus ''Citharichthys cornutus'', the horned whiff, is a species of flatfish in the large-tooth flounder family Paralichthyidae.

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Sex Characteristic
Secondary sex characteristics are features that appear during puberty in humans, and at sexual maturity in other animals. These characteristics are particularly evident in the sexually dimorphic phenotypic traits that distinguish the sexes of a species, but unlike the sex organs (primary sex characteristics), are not directly part of the reproductive system. Secondary sex characteristics are believed to be the product of sexual selection for traits which display fitness, giving an organism an advantage over its rivals in courtship and in aggressive interactions. Secondary sex characteristics include, for example, the manes of male lions, the bright facial and rump coloration of male mandrills, and horns in many goats and antelopes. These characteristics are believed to be produced by a positive feedback loop known as the Fisherian runaway produced by the secondary characteristic in one sex and the desire for that characteristic in the other sex.

Horned Whiff
''Citharichthys cornutus'', the horned whiff, is a species of flatfish in the large-tooth flounder family Paralichthyidae. This bathydemersal marine fish inhabits the continental shelves of the western Atlantic Ocean, in both tropical and subtropical waters. It ranges from New Jersey in the north to Uruguay in the south, though larvae samples have also been collected off the coast of Canada. It occurs at depths between , though it is usually found in deeper waters. Like the rest of the large-tooth flounders, it has both eyes on the left side of its head. It grows to a maximum length of . It is similar in appearance to '' C. gymnorhinus'' and '' C. amblybregmatus'', both of which are sympatric species. All three species display sexual dimorphism, with the males displaying several secondary sex characteristics. Due to its diminutive size and the abundance of larger flatfishes, it is of no commercial importance, and is rarely collected. As a result, the fishes' morphology and ecolog ...

Copeia
''Ichthyology & Herpetology'' (formerly ''Copeia'') is a quarterly peer-reviewed scientific journal covering research in ichthyology and herpetology that was originally named after Edward Drinker Cope, a prominent American researcher in these fields. It is the official journal of the American Society of Ichthyologists and Herpetologists. According to the ''Journal Citation Reports'', ''Copeia'' has a 2021 impact factor of 1.857, ranking it 65th out of 176 journals in the category "Zoology". History On December 27, 1913, John Treadwell Nichols published the first issue of ''Copeia''. This issue consisted of a single piece of paper folded to form four pages of information with five articles. The cover of the pamphlet bore the inscription: "Published by the contributors to advance the science of coldblooded vertebrates." In 2020, the American Society of Ichthyologists and Herpetologists voted to rename the journal, Ichthyology & Herpetology. Name change The journal was na ...

Citharichthys
''Citharichthys'' is a genus of flatfish in the large-tooth flounder family, Paralichthyidae. They have both eyes on the left sides of their heads. They are native to the oceans around the Americas, with a single species, ''C. stampflii'' off the West African coast. Most are found in relatively shallow depths, but the genus also includes species found in deep water (down to at least ) and species that enter fresh water. Various species known as sanddab, whiff, and flounder are in this genus, and the most common species is the Pacific sanddab, ''Citharichthys sordidus''. They are a dull light-brown, and are mottled with brown or black, sometimes with yellow or orange. The largest species reaches in length. Species The currently recognized species in this genus are: * ''Citharichthys abbotti'' C. E.
