Gobies
Gobiidae or gobies is a family of bony fish in the order Gobiiformes, one of the largest fish families comprising over 2,000 species in more than 200 genera. Most of gobiid fish are relatively small, typically less than in length, and the family includes some of the smallest vertebrates in the world, such as '' Trimmatom nanus'' and '' Pandaka pygmaea''. ''Trimmatom nanus'' are under long when fully grown, while the ''Pandaka pygmaea'' standard length is , with a maximum known standard length of . Some large gobies can reach over in length, but that is exceptional. Generally, they are benthic or bottom-dwellers. Although few are important as food fish for humans, they are of great significance as prey species for other commercially important fish such as cod, haddock, sea bass and flatfish. Several gobiids are also of interest as aquarium fish, such as the dartfish of the genus '' Ptereleotris''. Phylogenetic relationships of gobiids have been studied using molecular ...

Gobiiformes
Gobiiformes (meaning "goby-like") is an order of percomorph fish containing three suborders: Apogonoidei, Trichonotoidei, and Gobioidei. The order was formerly defined as containing only the gobies (now placed within the Gobioidei). However, more recent taxonomic treatments also place their close relatives (the cardinalfishes, nurseryfishes, and sand-divers) with them, based on phylogenetic studies that unexpectedly found a close relationship between these groups. The Gobioidei are the most speciose clade of the family. Despite the differing appearances of members of this group, all share the trait of adhesive eggs with elaborate structures. Many species within this group also display elaborate forms of parental care by the male. Gobiiforms are a relatively basal clade of the percomorphs, with only the ophidiiforms and batrachoidiforms being more basal. They are estimated to have diverged from the rest of the group during the early-to-mid Cretaceous (about 120 million ...

Neogobius Fluviatilis
The monkey goby (''Neogobius fluviatilis'') is a species of goby native to the basins of the Black Sea and the Sea of Azov. Characteristics The monkey goby is covered with cycloid scales on the head, nape, back, one third of the gill covers, bases of the pectoral fins, and the posterior half of the throat and belly. Its second dorsal fin is small in size compared to the posterior end of the body. The width of its head is equal to or a bit greater than the height of the head, and terminates in an acuminated, or leaf-shaped, snout. The jaws of ''Neogobius fluviatilis'' contain small, conical teeth and the mandibles are set forward in the skull. The abdomen of the monkey goby is lined with suckers that stretch from the collar to the anus. Its coloration is a brownish gray or a yellowish gray, usually with a very pale brown pattern of dark merged spots. Rows of dark spots are also found on the dorsal and caudal fins. The average adult monkey goby measures 7–10 centimeters, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Benthic 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 per cent), whereas pelagic fish can contain up to 30 pe ...

Common Goby
The common goby (''Pomatoschistus microps'') is a species of ray-finned fish native to fresh and brackish waters along the Atlantic and Baltic Sea coasts of Europe and northern Africa, with a range stretching from Norway to Morocco and Mauritania. It is also found in the Canary Islands. This species reaches a maximum length of TL.

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] [Amazon] |
Flatfish
A flatfish is a member of the Ray-finned fish, ray-finned demersal fish Order (biology), 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 Threadfin, threadfins, do not resemble the flatfish but are their closest relatives. 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 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 inc ...
