Pomatoschistus nanus is a species of goby native to the Levantine coast, in the Turkish territory. it is the smallest species of goby ever described in the Mediterranean sea. [1] [2] [3]
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 10 cm (3.9 in) 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 1 cm long when fully grown, then Pandaka pygmaea standard length are 9 mm (0.35 in), maximum known standard length are 11 mm (0.43 in). Some large gobies can reach over 30 cm (0.98 ft) 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.
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 20 to 30 metres though it can occasionally be found in outer reef areas and lagoons at depths of from 5 to 35 metres. This species can reach a length of 1 centimetre (0.39 in) SL.
The sand goby, also known as a polewig or pollybait, is a species of ray-finned fish native to marine and brackish European waters from the Baltic Sea through the Mediterranean Sea and into the Black Sea where it occurs in sandy or muddy areas of inshore waters at depths of from 4 to 200 metres. This species can reach a length of 11 centimetres (4.3 in) TL. This species is sometimes kept in public aquariums. The sand goby is of a sandy colour, with darker markings on the sides and a creamy-white underside. In the breeding season the male fish has blue spot at the rear of the first dorsal fin, ringed with white. The fish has a slender body, and the head is about a quarter of the total length.
Pomatoschistus canestrinii, Canestrini's goby, is a species of goby native to fresh and brackish waters along the Adriatic coasts where it is known to occur from the Po delta, Italy to Neretva, Croatia. It has also been introduced in Lake Trasimeno, Italy. This species prefers areas with sand or mud substrates in lagoons, lakes and medium-sized to large-sized rivers. This species can reach a length of 5.5 centimetres (2.2 in) TL. The specific name honours the Italian biologist Giovanni Canestrini (1835-1900).
Pomatoschistus is a genus of gobies native to fresh, brackish and marine waters of Europe, the eastern Atlantic Ocean and the Mediterranean Sea.
The two-spotted goby is a species of goby native to marine and brackish waters of the eastern Atlantic Ocean where it can be found from the Faeroes and Norway to the northwestern coast of Spain. It has also been recorded from Estonia though records from the Mediterranean Sea are uncertain. They are common on all coasts of the United Kingdom. This species can reach a length of 6 centimetres (2.4 in) TL.
The common goby 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 9 centimetres (3.5 in) TL.
The painted goby is a small goby of Western European waters from Trondheim Fjord to Spain, the Canary Islands and is sometimes reported in the Mediterranean Sea. Also mentioned in the Black Sea. It lives at depths from 1 to 55 metres, preferring a gravelly or sandy environment. Its young may sometimes be found in tide pools. It feeds on amphipods and copepods.
The grass goby is a species of goby native to the Mediterranean Sea, the Sea of Azov and the Black Sea. It is the only known member of its genus.
Pomatoschistus marmoratus, the marbled goby, is a species of goby native to the eastern Atlantic from the Bay of Biscay down around the Iberian Peninsula through the Mediterranean Sea, the Black Sea and the Sea of Azov. It is also found in the Suez Canal in Egypt. It occurs in marine and brackish waters on sandy substrates in shallow waters, typically down to 20 m (66 ft), but occasionally to 70 m (230 ft) in the winter. It can reach a length of 8 cm (3.1
Pomatoschistus norvegicus, the Norway goby, is a species of goby native to the eastern Atlantic from Lofoten to the western English Channel and has also been recorded from the Mediterranean Sea. It occurs in offshore waters at depths of from 18 to 325 metres, being found on substrates of mud or coarse shell fragments. This species can reach a length of 8 centimetres (3.1 in) TL.
True gobies were a subfamily, the Gobiinae, of the goby family Gobiidae, although the 5th edition of the Fishes of the World does not subdivide the Gobiidae into subfamilies. They are found in all oceans and a few rivers and lakes, but most live in warm waters. Altogether, the Gobiinae unite about 1149 described species in 160 genera, and new ones are still being discovered in numbers.
Pomatoschistus bathi is a species of goby native to the eastern Mediterranean and the Sea of Marmara where it occurs at depths of from 7 to 14 metres on substrates with a sand or mud component. This species can reach a length of 3 centimetres (1.2 in) TL. It is found in Mediterranean Sea and Black Sea, with scattered records in southwestern France to Turkish Aegean Sea coast. The Bath's goby feeds on bosmiden, brine shrimps, lobster eggs, oyster eggs, zoobenthos and zooplankton. In 2013, it was listed as data deficient but was changed to Least Concern the following year because the population is thought to stable, it may be under-represented and there are no known threats. The specific name honours the German ichthyologist Hans Walter Bath (1924-2015).
Pomatoschistus quagga, the Quagga goby, is a species of goby native to the western part of the Mediterranean Sea and the Adriatic Sea. It occurs above soft substrates and in beds of eelgrass. This species can reach a length of 6 centimetres (2.4 in) TL.
Pomatoschistus tortonesei, Tortonese's goby, is a species of goby native to the Mediterranean Sea where it is known from Marsala, Sicily and the Farwah Lagoon in western Libya. This species occurs in shallow waters ranging in salinity from brackish to just slightly hypersaline. It prefers habitats with sandy substrates near to beds of seagrass. Its diet consists of small crustaceans and gastropods. It is threatened by the fragmentation and destruction of its preferred habitat by silting. The specific name honours the Italian zoologist Enrico Tortonése (1911-1987) of the Museo Civico di Storia Naturale di Genova.
Pomatoschistus knerii, Kner's goby, is a species of goby native to the western basin of the Mediterranean Sea and the Adriatic Sea. This species occurs in areas with soft substrates near to rocks or beds of seagrass. The specific name most likely honours the Austrian ichthyologist Rudolf Kner (1810-1869), who was a friend of the author Franz Steindachner.
Pomatoschistus lozanoi, Lozano's goby, is a species of goby native to the northeastern Atlantic Ocean from the North Sea to northwestern Spain and Portugal where it can be found at depths of from 70 to 80 metres. This species can reach a length of 8 centimetres (3.1 in) TL and is known to live for only two years. The specific name honours the Spanish zoologist Luis Lozano Rey (1878-1958).
Bothriocephalus gregarius is a tapeworm that parasitises the turbot. It has a complex life cycle including two intermediate hosts, a copepod and a small fish.
