Stout Infantfish
''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''.

Dorsal Fin
A dorsal fin is a fin on the back of most marine and freshwater vertebrates. Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous. They are found in most fish, in mammals such as whales, and in extinct ancient marine reptiles such as ichthyosaurs. Most 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 whales to identify individuals in the field. The bones or cartilages that support the dorsal fin in fish are called pterygiophores. Functions The main purpose of the dorsal fin is usually to stabilize the animal against rolling and to assist in sudden turns. Some species have further adapted their dorsal fins to other uses. The sunfish uses the dorsal fin (and the anal fin Fins are moving appendages protruding from the body of fish that interact with water to ge ...

Anal Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish ( Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish ( Chondrichthyes) and jawless fish ( Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Photocorynus Spiniceps
''Photocorynus'' is a monospecific genus of marine life, marine Actinopterygii, ray-finned fish belonging to the family leftvent, Linophrynidae, the leftvents. The only species in the genus is ''Photocorynus spiniceps''. ''Photocorynus'' was first proposed as a genus in 1925 by the English ichthyologist Charles Tate Regan when he Species description, described its only species, ''P. spiniceps''. The holotype of ''P. spiniceps'' was collected by the Danish research vessel ''Dana (1921), Dana'' from the Gulf of Panama at 7°15'N, 78°54'W, from a depth of around . The 5th edition of ''Fishes of the World'' classifies this taxon in the family Linophrynidae, within the suborder Ceratioidei, the deep sea anglerfishes, of the anglerfish Order (biology), order Lophiiformes. ''Photocorynus'' means "light club", an allusion to the Bioluminescence, bioluminescent sac at the end of the short, club-like Illicium (fish anatomy), illicium.

Anglerfish
The anglerfish are ray-finned fish in the order Lophiiformes (). Both the order's common name, common and scientific name comes from the characteristic mode of predation, in which a modified dorsal Fish fin#Ray-fins, fin ray acts as a Aggressive mimicry#Food as an attractant, lure for prey (akin to a human Angling, angler, and likened to a crest or "''wikt:Lophius, lophos''"). The modified fin ray, with the very tip being the Esca (fish anatomy), esca and the length of the structure the Illicium (fish anatomy), illicium, is adapted to attract specific prey items across the families of anglerfish by using different luring methods. Anglerfish occur worldwide. The majority are bottom-dwellers, being demersal fish, while the aberrant deep-sea anglerfish are Pelagic fish, pelagic, (mostly) living high in the water column. Some live in the Deep-sea fish, deep sea (such as the deep-sea anglerfish and sea toads), while others live in Shallow water marine environment, shallower waters, s ...

Paedophryne Amauensis
''Paedophryne amauensis'', also known as the New Guinea Amau frog, is a species of microhylid frog endemic to eastern Papua New Guinea. At in snout-to-vent length, it was once 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 bee ...

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 organisms (microrganisms) may be nanobes that can be 20 nanometers long. 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 491 Kbp 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 .

Standard Length
Fish measurement is the measuring of individual fish and various parts of fish anatomy, their anatomies, for data used in many areas of ichthyology, including Taxonomy (biology), taxonomy and fishery 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 Glossary of ichthyology#H, hypural plate. This measurement excludes the length of the caudal fin, 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 Actinopterygii, bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys) and usually Elasmobranchii (shark ...
