Schindleriidae
''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. Description The infant fishes are so called because they retain many of their larval characteristics (an example of neoteny). Their elongated bodies are transparent, and many of the bones never develop. ''S. praematura'' reaches a length of . All of the ''Schindleria'' species are reef fishes. They may be among the most common fish of the reefs, based on the results of plankton tows, but because of their transparency and small size, they are infrequently seen in life. A r ...

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''.

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.

Gobioidei
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 Gobiida ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gobiidae
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. Descript ...

Otto Schindler (zoologist)
Otto Schindler (1906–1959) was a German zoologist who specialised in ichthyology. In 1931 he joined the Bavarian State Collection of Zoology (Zoologische Staatssammlung München) as an assistant curator of ichthyology, to work on the specimens collected by the III German Grand Chaco Expedition to East Paraguay. In 1937 he joined the IV expedition to Brazil which lasted 6 months. After the Second World War he was appointed Curator of Ichthyology and restored and ordered the collection of fish which had survived the war. It is known that he visited Stockholm in the 1950s, bringing some specimens from the museums there back to Munich. He also obtained specimens from Vienna as part of his efforts to rebuild the ZSM collection. He returned to South America in 1953-54, travelling to Bolivia with Walter Forster; during this expedition Schindler was appointed to negotiate the fishing quotas on Lake Titicaca with Peru by the Bolivian Ministry of Agriculture; the Peruvian negotiator was ano ...

Neoteny
Neoteny (), also called juvenilization,Montagu, A. (1989). Growing Young. Bergin & Garvey: CT. is the delaying or slowing of the physiological, or somatic, development of an organism, typically an animal. Neoteny is found in modern humans compared to other primates. In progenesis or paedogenesis, sexual development is accelerated. Both neoteny and progenesis result in paedomorphism (as having the form typical of children) or paedomorphosis (changing towards forms typical of children), a type of heterochrony. It is the retention in adults of traits previously seen only in the young. Such retention is important in evolutionary biology, domestication and evolutionary developmental biology. Some authors define paedomorphism as the retention of larval traits, as seen in salamanders.Schell, S. C. ''Handbook of Trematodes of North America North of Mexico'', 1985, pg. 22 History and etymology The origins of the concept of neoteny have been traced to the Bible (as argued by Ashley Monta ...

Ryukyu Islands
The , also known as the or the , are a chain of Japanese islands that stretch southwest from Kyushu to Taiwan: the Ōsumi, Tokara, Amami, Okinawa, and Sakishima Islands (further divided into the Miyako and Yaeyama Islands), with Yonaguni the westernmost. The larger are mostly high islands and the smaller mostly coral. The largest is Okinawa Island. The climate of the islands ranges from humid subtropical climate (Köppen climate classification ''Cfa'') in the north to tropical rainforest climate (Köppen climate classification ''Af'') in the south. Precipitation is very high and is affected by the rainy season and typhoons. Except the outlying Daitō Islands, the island chain has two major geologic boundaries, the Tokara Strait (between the Tokara and Amami Islands) and the Kerama Gap (between the Okinawa and Miyako Islands). The islands beyond the Tokara Strait are characterized by their coral reefs. The Ōsumi and Tokara Islands, the northernmost of the islands, fall un ...
