Schindleria brevipinguis is a species of marine fish in family Gobiidae of Perciformes. Known as the stout infantfish, it is native to Australia's Great Barrier Reef and to Osprey Reef in the Coral Sea. [2]
S. brevipinguis is among the smallest known fish in the world, together with species such as Paedocypris progenetica . Males of S. brevipinguis have an average standard length of 7.7 mm (0.30 in), a gravid female was 8.4 mm (0.33 in) and the maximum standard length of the species is 10 mm (0.39 in). [3] It held the record for the smallest known vertebrate, but now, by a measurement of snout-to-vent length, the smallest vertebrate species currently is the recently (Jan 2012) described frog Paedophryne amauensis , while the parasitic males of the anglerfish Photocorynus spiniceps are but 6.2 millimetres (0.24 in) long. S. brevipinguis is distinguished from the similar S. praematura by having its first anal-fin ray further forward, under dorsal-fin 4, rather than 7–11 in S. praematura. Like most closely related fishes, the fish is very thin, and one specimen weighed just 0.7 milligrams. [2]
The specific epithet, brevipinguis, derives from the Latin brevis (short) and pinguis (stout), in reference to the fish's shorter, thicker body, as compared with other Schindleria species.
The first specimen was collected by Jeff Leis in 1979, but the species was not formally described until a 2004 paper (Watson and Walker).
Perciformes, also called the Percomorpha or Acanthopteri, is an order or superorder of ray-finned fish. If considered a single order, they are the most numerous order of vertebrates, containing about 41% of all bony fish. Perciformes means "perch-like". Perciformes is an order within the Clade Percomorpha consisting of "perch-like" Percomorphans. This group comprises over 10,000 species found in almost all aquatic ecosystems.
The Coral Sea is a marginal sea of the South Pacific off the northeast coast of Australia, and classified as an interim Australian bioregion. The Coral Sea extends 2,000 kilometres (1,200 mi) down the Australian northeast coast. Most of it is protected by the French Natural Park of the Coral Sea and the Australian Coral Sea Marine Park. The sea was the location for the Battle of the Coral Sea, a major confrontation during World War II between the navies of the Empire of Japan, and the United States and Australia.
Schindleria is a genus of marine fish. It was the only genus of family Schindleriidae, among the Gobioidei of order Perciformes but is now classified under the Gobiidae in the Gobiiformes. The type species is S. praematura, Schindler's fish. The Schindleria species are known generically as Schindler's fishes after German zoologist Otto Schindler (1906–1959), or infantfishes. They are native to the southern Pacific Ocean, from the South China Sea to the Great Barrier Reef off eastern Australia.
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.
Paedocypris progenetica is a species of tiny cyprinid fish endemic to the Indonesian islands of Sumatra and Bintan where it is found in peat swamps and blackwater streams. It was discovered by Singaporean ichthyologist Heok Hui Tan. He has written a description of the fish along with another species of the same genus called Paedocypris micromegethes.
The barred fingerfin is a species of marine ray-finned fish, belonging to the family Cheilodactylidae, commonly referred to as morwongs. It is found only in the southeastern Atlantic and southwestern Indian Oceans off the coasts of South Africa.
The golden trevally, also known as the golden kingfish, banded trevally or king trevally, is a species of large marine fish classified in the jack and horse mackerel family Carangidae, and the only member of the monospecific genus Gnathanodon. The golden trevally is widely distributed throughout the tropical and subtropical waters of the Indian and Pacific Oceans, ranging from South Africa in the west to Central America in the east, extending to Japan in the north and Australia in the south. The species predominantly occupies inshore waters where it inhabits both reef and sandy substrates. The golden trevally is easily distinguished from its relatives by its fleshy, rubbery lips and unique colouration, which ranges from bright yellow with black bars as a juvenile to a golden-silvery colour as an adult. It is known to grow to 120 centimetres (47 in) in length and 15 kilograms (33 lb) in weight. The golden trevally schools as a juvenile, often closely following larger objects including sharks and jellyfish. The species uses its protractile jaws to suck out prey from the sand or reef, and consumes a variety of fish, crustaceans and molluscs. Spawning aggregations gather at night at different times of the year throughout its range. The golden trevally is a considerable constituent of several Middle Eastern fisheries and being of minor importance to many others, with a worldwide annual catch of 1,187 metric tons to 3,475 metric tons recorded between 2000 and 2010. The golden trevally is a popular gamefish, taken by bait, lure, fly and also spear throughout its range. Several Asian countries currently farm the fish in caged aquaculture. Due to their brilliant colouration, juveniles are popular in marine aquaria.
The smallest organisms found on Earth can be determined according to various aspects of organism size, including volume, mass, height, length, or genome size.
The blacktip grouper, also known as the redbanded grouper, blacktipped cod, black-tipped rockcod, footballer cod, red-barred cod, red-barred rockcod, scarlet rock-cod or weathered rock-cod, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the tropical Indo-Pacific region. It is the type species of the genus Epinephelus.
The rainbow runner, also known as the rainbow yellowtail, Spanish jack and Hawaiian salmon, is a common species of pelagic marine fish of the jack family, Carangidae. The species is widespread throughout the tropical and subtropical waters of the world, inhabiting both coastal and offshore areas. The species is the only member of the genus Elagatis, which was created 15 years after its initial description, and is closely related to the amberjacks. The rainbow runner is easily distinguished by its body shape, and the brilliant colouration which gives the fish its name. It is a fast-swimming predator, taking small fish, cephalopods, and a wide variety of planktonic crustaceans. The species reaches sexual maturity around 60 cm (24 in), and spawning takes place at different times, with some populations spawning year round, while others only spawn at certain times of the year. The species is a well known game fish, taken by a variety of fishing methods, and is a well-regarded table fish. Large numbers of the species are taken as bycatch in tuna- and shark-fishing operations and marketed.
The yellowtail scad, is an abundant species of small inshore marine fish of the jack family, Carangidae. The species is widespread in the Indo-Pacific region from east Africa in the west to Hawaii in the east, extending north to Japan and south to Australia. The yellowtail scad is the only member of the monotypic genus Atule and is distinguished from similar species by a well-developed adipose eyelid and finlet-like extensions of the last rays of the dorsal and anal fins. It inhabits coastal areas such as bays and coral reefs, preying on small fishes and crustaceans. Spawning has been well studied in Hawaii, where fish enter bays to spawn, releasing up to 161,000 eggs each between March and October. The yellowtail scad is an important component of fisheries throughout its range, taken by a number of netting and hook-and-line methods. It is a prized food fish in some regions and is cooked or preserved by a variety of methods.
Plectropomus laevis, known commonly as the black-saddled coral grouper, cluespotted coral trout, blacksaddled coral trout, blue-spot trout, Chinese footballer, footballer cod, footballer coral trout, oceanic coral trout or tiger trout, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the Indo-Pacific region.
Parascorpaena mossambica, the Mozambique scorpionfish, is a species of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. This species is native to the Indian Ocean and the Pacific Ocean to Micronesia, although the Pacific populations may be a separate species. It occasionally makes its way into the aquarium trade. It grows to a length of 10 centimetres (3.9 in) TL.
Schindleria praematura, Schindler's fish is a species of neotenic goby which was formerly placed in the monogeneric family Schindleriidae but which is currently classified within the Gobiidae. It is associated with reefs and has an Indo-Pacific distribution from South Africa and Madagascar to Hawaii and the sea mounts of the South Pacific. The generic name and the common name honour the German zoologist Otto Schindler (1906–1959) who described the species.
