Schindleria Brevipinguis
''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. Anatomy ''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 , a gravid female was and the maximum standard length of the species is . 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 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''.

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans (whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against rollin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...

Schindleria Praematura
''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. In popular culture The song "The Fish (Schindleria Praematurus)" by the British rock group Yes, from their 1971 album ''Fragile'', refers to this species albeit with an incorrect spelling of the species name. The genus name is sung as "shine-duh-leer-ee-ah" by bassist Chris Squire & vocalist Jon Anderson John Roy Anderson (born 25 October 1944) is an English singer, songwriter and musician, best known as the lead singer of the progressive rock band Yes, which he formed in 1968 with bassist Chris Squire.

Photocorynus Spiniceps
''Photocorynus spiniceps'' is a species of anglerfish in the family Linophrynidae. It is in the monotypic genus ''Photocorynus''. The known mature male individuals are 6.2–7.3 millimeters (0.25-0.3 inches), smaller than any other mature fish and vertebrate; the females, however, reach a significantly larger size of up to 50.5 millimeters (2 inches). (However, numerous fish species have ''both'' sexes reaching maturity below 20 millimeters (0.8 inches).) Like most other deepsea anglerfishes, ''Photocorynus spiniceps'' lures its prey into striking range using a bioluminescent sac at the end of an illicium, the highly modified first ray of the dorsal fin, and swallows the prey whole with the help of a distending jaw and a similarly distending stomach. Its prey can sometimes be as big as their own bodies. The male spends its life fused to its much larger female counterpart, therefore effectively turning her into a hermaphrodite. While the female t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anglerfish
The anglerfish are fish of the teleost order Lophiiformes (). They are bony fish named for their characteristic mode of predation, in which a modified luminescent fin ray (the esca or illicium) acts as a lure for other fish. The luminescence comes from symbiotic bacteria, which are thought to be acquired from seawater, that dwell in and around the sea. Some anglerfish are notable for extreme sexual dimorphism and sexual symbiosis of the small male with the much larger female, seen in the suborder Ceratioidei, the deep sea anglerfish. In these species, males may be several orders of magnitude smaller than females. Anglerfish occur worldwide. Some are pelagic (dwelling away from the sea floor), while others are benthic (dwelling close to the sea floor). Some live in the deep sea (such as the Ceratiidae), while others on the continental shelf, such as the frogfishes and the Lophiidae (monkfish or goosefish). Pelagic forms are most often laterally compressed, whereas the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paedophryne Amauensis
''Paedophryne amauensis'' is a species of microhylid frog endemic to eastern Papua New Guinea. At in snout-to-vent length, it is considered the world's smallest known vertebrate. (See also Ecological guild.) The species was listed in the ''Top 10 New Species 2013'' by the International Institute for Species Exploration for discoveries made during 2012. Discovery The frog species was discovered in August 2009 by Louisiana State University herpetologist Christopher Austin and his PhD student Eric Rittmeyer while on an expedition to explore the biodiversity of Papua New Guinea. The new species was found near Amau village in the Central Province, from which its specific name is derived. The discovery was published in the peer-reviewed scientific journal PLOS One in January 2012. Because the frogs have calls that resemble those made by insects and are camouflaged among leaves on the forest floor, ''Paedophryne amauensis'' had been difficult to detect.

Smallest Organisms
The smallest organisms found on Earth can be determined according to various aspects of organism size, including volume, mass, height, length, or genome size. Given the incomplete nature of scientific knowledge, it is possible that the smallest organism is undiscovered. Furthermore, there is some debate over the definition of life, and what entities qualify as organisms; consequently the smallest known organism (microorganism) is debatable. Microorganisms Obligate endosymbiotic bacteria The genome of '' Nasuia deltocephalinicola'', a symbiont of the European pest leafhopper, '' Macrosteles quadripunctulatus'', consists of a circular chromosome of 112,031 base pairs. The genome of ''Nanoarchaeum equitans'' is 490,885 nucleotides long. ''Pelagibacter ubique'' ''Pelagibacter ubique'' is one of the smallest known free-living bacteria, with a length of and an average cell diameter of . They also have the smallest free-living bacterium genome: 1.3 Mbp, 1354 protein genes, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard Length
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.
