Gobiid
Gobiidae or gobies is a family of bony fish in the order Gobiiformes, one of the largest fish families comprising more than 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, then ''Pandaka pygmaea'' standard length are , maximum known standard length are . 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 data. Descriptio ...

Gobiiformes
The Gobiiformes are an order of fish that includes the gobies and their relatives. The order, which was previously considered a suborder of Perciformes, is made up of about 2,211 species that are divided between seven families. Phylogenetic relationships of the Gobiiformes have been elucidated using molecular data. Gobiiforms are primarily small species that live in marine water, but roughly 10% of these species inhabit fresh water. This order is composed chiefly of benthic or burrowing species; like many other benthic fishes, most gobiiforms do not have a gas bladder or any other means of controlling their buoyancy in water, so they must spend most of their time on or near the bottom. Gobiiformes means "Goby-like". Families The 5th Edition of the '' Fishes of the World'' reclassified the former superfamily Goboidei as the order Gobiiformes and also rearranged the families within the order compared to the previous edition. The largest change is that the Oxudercidae and the Gobii ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ponticola Kessleri
''Ponticola kessleri'', the bighead goby or Kessler's goby, is a species of goby native to Eurasia. The bighead goby is a Ponto-Caspian relict species. It inhabits the fresh and oligohaline waters, with mineralisation from 0-0.5‰ up to 1.5-3.0‰. 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; ctenoid scales ...

Pelvic Fins
Pelvic fins or ventral fins are paired fins located on the ventral surface of fish. The paired pelvic fins are homologous to the hindlimbs of tetrapods. Structure and function Structure In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays (lepidotrichia) are positioned distally from the radials. There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. Pelvic fin structures can be extremely specialized in actinopterygians. Gobiids and lumpsuckers modify their pelvic fins into a sucker disk that allow them to adhere to the substrate or climb structures, such as waterfalls. In priapiumfish, males have modified their pelvic structures into a spiny copulatory device that grasps the female during mating.

Pandaka Pygmaea
The dwarf pygmy goby or Philippine goby (''Pandaka pygmaea'') is a tropical species of fish in the subfamily Gobionellinae from brackish water and mangrove areas in Southeast Asia. It is one of the smallest fish species in the world. Males reach maturity at a standard length of and can reach up to in standard length, while the females can grow up to in total length. Adults weigh around . It is known as ''bia'' and ''tabios'' in the Philippines., ''Guide to the Philippine Flora and Fauna, Band IX'', (undated). Distribution and habitat ''P. pygmaea'' was initially reported as being endemic to Malabon, Metro Manila in the Philippines, where found at shady river banks. The species has now been extirpated from this area as it was reclaimed, leading to its status as critically endangered by the IUCN. More recently, it has been discovered at a range of other locations in Southeast Asia, including Culion Island, Bali, Sulawesi and Singapore. As part of the aquarium trade, it was im ...

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. Description The common goby has two dorsal fins with a narrow gap between them, the anterior one consisting of six to eight spines and the posterior one eight to eleven soft rays. The pelvic fins are fused. There are 39 to 51 scales along the lateral line and these scales are slightly larger than those of the sand goby (''Pomatoschistus minutus''). The caudal fin is rounded. In males, there is a conspicuous dark spot on the anterior dorsal fin and dark markings at the base of the pectorals and the caudal fin. Otherwise the colour is light grey or sandy brown with indistinct dark markings and dark striations on the pale fins. The colour of the male da ...
