Pleuronectiformes
A flatfish is a member of the ray-finned demersal fish suborder Pleuronectoidei, also called the Heterosomata. 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. The most primitive members of the group, the threadfins, do not resemble the flatfish but are their closest relatives. Many important food fish are in this order, including the flounders, soles, turbot, plaice, and halibut. Some flatfish can camouflage themselves on the ocean floor. Taxonomy Due to their highly distinctive morphology, flatfishes were previously treated as belonging to their own order, Pleuronectiformes. However, more recent taxonomic studies have found them to group within a diverse group of nektonic marine fishes known as the Carangiformes, which also includes jacks and billfish. Specifically, flatfish are m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scophthalmidae
The Scophthalmidae are a family (biology), family of flatfish found in the North Atlantic Ocean, Baltic Sea, Mediterranean Sea, and Black Sea. Fish of this family are known commonly as turbots, though this name can refer specifically to ''Scophthalmus maximus'', as well. Some common names found in species of this family are turbots, windowpanes, and brills. cladistics, Cladistic analysis reveals that this family is a monophyly, monophyletic group. Of all the scophthalmids, the largest species (''Turbot, Scophthalmus maximus'') reaches approximately one meter in length. Some species in the family have been historically Commercial fishing, fished commercially (predominantly the brill flatfish and the turbot flatfish, Brill (fish), ''S.rhombus'' and Turbot, ''S. maximus'' respectively). Taxonomy The ''Scophthalmidae'' family is composed of two main clades, four genera, and eight species. The four genera are ''Zeugopterus'', ''Lepidorhombus'', ''Phrynorhombus'', and ''Scophthalmus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samaridae
Samaridae (''crested flounders'') is a family of crested flounders, small flatfishes native to the Indo-Pacific. The family contains four genera with a total of 29 species. Taxonomy Samaridae is one of eight families a part of the SuperFamily Soleioidea. This SuperFamily is of the suborder Pleuronectoidei within the order Pleuronectiformes. Samaridae were formerly classified as a subfamily of Pleuronectidae. Anatomy and morphology Young flat fish are bilaterally symmetrical until they reach between 5 and 120mm in length when one eye shifts from the lower side to the upper side until it is adjacent to the other eye. Adult flat fish swim and lie on the side without eyes. Adult Samaridae are not bilaterally symmetrical but do have symmetrical pelvic fins. They have a highly compressed body with eyes that bulge above the body surface which allows them to see out while buried beneath a surface. Samaridae have countershaded coloring with a darker pigment on the top of the fish a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poecilopsettidae
The Poecilopsettidae are a family of flatfish, comprising three genera and 21 species. Species are typically demersal, living on marine bottoms at depths between in the Indo-Pacific and northwestern Atlantic; the deepest recorded occurrence is in the deepwater dab, ''Poecilopsetta beanii''. Sizes range from in length, though most species are usually under long. Diets consist of zoobenthos. In some traditional classifications, the group was recognisied as subfamily Poecilopsettinae in the family Pleuronectidae Pleuronectidae, also known as righteye flounders, are a family of flounders. They are called "righteye flounders" because most species lie on the sea bottom on their left sides, with both eyes on their right sides. The Paralichthyidae are the o ....

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 Ocean, Indian and Pacific Oceans. Several species are important commercial and game fishes, notably the California halibut, ''Paralichthys californicus'' and the Pacific sanddab, ''Citharichthys sordidus''. Phylogenetic analyses have long indicated the non-monophyly of this family e.g., and two lineages have been consistently apparent. Termed groups, the two groups were named after genera: a ''Cyclopsetta'' group and a ''Pseudorhombus'' group (see summary in ). A formal description of Cyclopsettidae in 2019 created this family consisting of four genera: ''Cyclopsetta'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhombosoleidae
Rhombosoleidae is a family of flatfish, comprising nine genera and 19 species; all members of this family are right eye flounders with asymmetrical pelvic fins. Species are typically demersal, living on bottoms in temperate marine waters on the continental shelf, although some species of '' Rhombosolea'' enter fresh water in New Zealand. Most are restricted to waters around Australia and New Zealand, though the Remo flounder, ''Oncopterus darwinii'', occurs in the southwestern Atlantic and the Indonesian ocellated flounder, ''Psammodiscus ocellatus'', occurs in Indonesia. In some traditional classifications, this group was formerly recognised as a subfamily, Rhombosoleinae, of the Pleuronectidae Pleuronectidae, also known as righteye flounders, are a family of flounders.

Soleidae
The true soles are a family, Soleidae, of flatfishes. It includes saltwater and brackish water species in the East Atlantic, Indian Ocean, West and Central Pacific Ocean, and the mediterranean sea. Freshwater species are found in Africa, southern Asia, New Guinea, and Australia. In the past, soles of the Americas (both fresh and salt water) were included in this family, but they have been separated to their own family, the American soles (Achiridae). The only true sole remaining in that region is '' Aseraggodes herrei'' of the Galápagos and Cocos Island. The true soles are bottom-dwelling fishes feeding on small crustaceans and other invertebrates. The family contains 30 genera and a total of about 180 species. Soles begin life as bilaterally symmetric larvae, with an eye on each side of the head, but during development, the left eye moves around onto the right side of the head. Adult soles lie on their left (blind) sides on the sea floor, often covered in mud, which in com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psettodidae
The spiny turbots are a family, Psettodidae, of relatively large, primitive flatfish found in the tropical waters of the east Atlantic and Indo-Pacific. The family contains just three species, all in the same genus, ''Psettodes''. The common name comes from the presence of spines in the dorsal and anal fins, which may indicate an evolutionary relationship with the Perciformes. They are less asymmetrical than other flatfish, although the region around the eyes is twisted. They reach lengths of . Species The currently recognized species in this genus are: * '' Psettodes belcheri'' E. T.

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Pleuronectes Platessa
The European plaice (''Pleuronectes platessa''), commonly referred to as simply plaice, is a species of marine flatfish in the genus Pleuronectes of the family Pleuronectidae. Description The European plaice is characterized, on their dorsal side, by their dark green to dark brown skin, blotched with conspicuous, but irregularly distributed, orange spots. The ventral side is pearly white. The skin is smooth with small scales. They are able to adapt their colour somewhat to match that of their surroundings, but the orange spots always remain visible. The skin lacks any prickles. The outline of adults is oval. The head is rather small and is less than 25% of the total length. The pointed mouth is terminal and fairly small with its maxilla reaching just below the right eye. Both eyes are located at the right side of the body. The bony ridge behind the eyes is another characteristic for this species. The lateral line curves slightly above the pectoral fin. The dorsal fin reaches t ...

Alfred Brehm
Alfred Edmund Brehm (; 2 February 1829 – 11 November 1884) was a German zoologist and writer. His multi-volume book '' Brehms Tierleben'', which he co-authored with Eduard Pechuël-Loesche, Wilhelm Haacke, and Richard Schmidtlein, became a household word for popular zoological literature. He was the first director of the Zoological Garden of Hamburg. Early life Brehm grew up in the small Thuringian village of Unter renthendorf as the son of the pastor Christian Ludwig Brehm, and of his second wife Bertha née Reiz. Christian Ludwig Brehm made a name for himself as an ornithologist by publications and through an extensive collection of stuffed birds. The collection, held in the parsonage and consisting of over 9,000 dead birds, offered a glimpse into the world of European birds. As a boy he helped expand his father by collecting specimens and became an excellent marskman. His father's research gave the younger Brehm an interest in zoology, but at first he wanted to be ...

10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' (Latin; the English title is ''A General System of Nature'') is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of ''Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Threadfin
Threadfins are silvery grey fish of the family Polynemidae, taxonomically considered a type of flatfish. Found in tropical to subtropical waters throughout the world, the threadfin family contains eight genera and about 40 species. An unrelated species sometimes known by the name threadfin, ''Alectis indicus'', is properly the Indian threadfish (family Carangidae). Ranging in length from in the dwarf threadfin (''Parapolynemus verekeri'') to in fourfinger threadfin (''Eleutheronema tetradactylum'') and giant African threadfin (''Polydactylus quadrifilis''), threadfins are both important to commercial fisheries as a food fish, and popular among anglers. Their habit of forming large schools makes the threadfins a reliable and economic catch. Description Their bodies are elongated and fusiform, with spinous and soft dorsal fins widely separated. Their tail fins are large and deeply forked, indicating speed and agility. The mouth is large and inferior; a blunt snout project ...
