Gobiidae
Gobiidae or gobies is a family (biology), family of bony fish in the order (biology), order Gobiiformes, one of the largest fish families comprising over 2,000 species in more than 200 genus, 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 fish, 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, barramundi, sea bass and flatfish. Several gobiids are also of interest as aquarium fish, such as the dartfish of the genus ''Ptereleotris''. Phylogenetic rela ...

Racer Goby
The racer goby (''Babka gymnotrachelus'') is a species of goby native to fresh water, fresh, sometimes brackish water, brackish, waters, of the Black Sea basin. It is a Ponto-Caspian Relict (biology), relict species. The species is placed a monotypic genus, ''Babka'', which was once considered a subgenus of genus ''Neogobius'', but was then elevated to genus-status based on the Molecular phylogenetics, molecular analysis. Characteristics It has 7–8 Dorsum (anatomy), dorsal spines, 14–18 dorsal soft Ray (fish fin anatomy), rays, a single Anal fin, anal spine and 12–16 anal soft rays. This species is distinguished from its relatives in ''Neogobius'' based on multiple characteristics. ''B. gymnotrachelus'' has diagonal bars of irregular position and shape. The first branched ray of second dorsal is about as long as its penultimate ray. It lacks scales on the midline of its nape, anterior to its preoperculum. It has a pelvis, pelvic-disc frenulum, fraenum with smal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Characteristics This species has a big flattened head, strongly expended upper lip, prolonged-conical body and thickened anterior. The mandibula is longer than maxilla. It reaches . A triangular dark spot is visible near the caudal fin. The collar of its abdominal sucker has blades. The sucker does not reach the anus. It is red- or grey-brown with 5 transverse lines on the back, one of which is on the basis of the caudal fin. The head has light round spots with a white margin on sides. The basis of the pectoral fin has wave-shaped brown spots, odd fins have lines of black spots. This species is distinguished from related Black Sea basin inhabitants by the following: 75–95% of its length is between its origin and anus; ctenoi ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trimmatom Nanus
''Trimmatom nanus'', the midget dwarfgoby, is a species of marine goby native to the Indian Ocean and the western Pacific Ocean. It can mainly be found on oceanic drop-offs at depths of from though it can occasionally be found in outer reef areas and lagoons at depths of from . This species can reach a length of SL. ''T. nanus'' was until 2004 the smallest known fish and vertebrate. The recent discovery of ''Schindleria brevipinguis'' (called the stout infantfish) relegated it to second place. Later, the discovery of ''Paedocypris progenetica'' dropped ''T. nanus'' to third place. The record for the smallest known vertebrate being held by the frog ''Paedophryne amauensis ''Paedophryne amauensis'', also known as the New Guinea Amau frog, is a species of microhylid frog endemic to eastern Papua New Guinea.
