Assiculus
''Assiculus'' is a genus of fish in the "dottyback" family Pseudochromidae. It is monotypic, containing only ''Assiculus punctatus''. It is a small species of dottyback which is covered in small, bright blue spots. The males are bluish in colour while the females are greenish-yellow and are smaller than the males. ''A. punctatus'' is found in coastal areas in the vicinity of reefs and weedy areas; normally in rather turbid waters as deep as . This secretive species frequents areas where there are highly eroded limestone reefs and rocks. The genus and species were first published by Sir John Richardson in an appendix to Volume 1 of John Lort Stokes' 1846 ''Discoveries in Australia''. The specific name Specific name may refer to: * in Database management systems, a system-assigned name that is unique within a particular database In taxonomy, either of these two meanings, each with its own set of rules: * Specific name (botany), the two-part (bino ...

Pseudochrominae
Pseudochrominae is a subfamily of ray-finned fishes, one of four subfamilies that make up the family Pseudochromidae, the species within the subfamily are commonly called dottybacks. They are small reef-associated marine fish which have an Indo-Pacific distribution. Characteristics In the Pseudochrominae the pelvic fin has a single spine and five rays which are branched, the head is covered in scales, there are teeth on the palatine bone and there are 16-20 rays in the pectoral fin. The lateral line is divided into two, with a longer part running from the head to the posterior part of the dorsal fin and located just below the dorsal fin and the other, shorter part on the rear of the flanks. They grow to a maximum length of . Distribution The subfamily Pseudochrominae has a widespread distribution in the Indian Ocean and western Pacific Ocean, mainly in tropical areas. Their distribution extends from the eastern coast of Africa, east across the Indo-Pacific region to America ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dottyback
The dottybacks are a family, Pseudochromidae, of fishes which were formerly classified in the order Perciformes, but this has been revised and the family is regarded as of uncertain affinities, or ''incertae sedis'' within the Ovalentaria, a clade within the Percomorpha. Around 152 species belong to this family. They are found in the tropical and subtropical Indo-Pacific, where most inhabit coral reefs. Many species are brightly coloured fish, often showing striking sexual dimorphism. They are generally small, mostly less than in length, and some less than . The largest by far, at up to , is '' Congrogadus subducens''.Lieske, E., and Myers, R. (1999). Coral Reef Fishes. 2nd edition. Princeton University Press. Dottybacks are distinguished from other families by the presence of three or less spines in the dorsal fin and an incomplete lateral line organ. Several of the brightly coloured members of the family are often seen in the marine aquarium trade, although some species a ...

John Lort Stokes
Admiral John Lort Stokes, RN (1 August 1811 – 11 June 1885)Although 1812 is frequently given as Stokes's year of birth, it has been argued by author Marsden Hordern that Stokes was born in 1811, citing a letter by fellow naval officer Crawford Pasco congratulating him on his birthday in 1852. was an officer in the Royal Navy who travelled on for close to eighteen years. Biography Born on 1 August 1811, son of Henry Stokes, of Scotchwell, near Haverfordwest, Pembrokeshire, and Anne, daughter of Dr George Phillips, Stokes joined the Royal Navy on 20 September 1824. The first ship he served on was , and then in October 1825 he joined the crew of ''Beagle'' under Captain Phillip Parker King. ''Beagle'' was involved in a survey of the waters of South America. In 1828 the commander of HMS ''Beagle'', Pringle Stokes (not related to John Lort Stokes), committed suicide and Robert FitzRoy assumed command; the ship returned to England in 1830 and was recommissioned.

John Richardson (naturalist)
Sir John Richardson Royal Society of London, FRS FRSE (5 November 1787 – 5 June 1865) was a Scotland, Scottish naval surgeon, natural history, naturalist and Arctic explorer. Life Richardson was born at Nith Place in Dumfries the son of Gabriel Richardson, Provost of Dumfries, and his wife, Anne Mundell. He was educated at Dumfries Grammar School. He was then apprenticed to his maternal uncle, Dr James Mundell, a surgeon in Dumfries. He studied medicine at Edinburgh University, and became a surgeon in the navy in 1807. He traveled with John Franklin in search of the Northwest Passage on the Coppermine Expedition of 1819–1822. Richardson wrote the sections on geology, botany and ichthyology for the official account of the expedition. Franklin and Richardson returned to Canada in 1825 and went overland by fur trade routes to the mouth of the Mackenzie River. Franklin was to go as far west as possible and Richardson was to go east to the mouth of the Coppermine River. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Fish Of Australia
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...

Fauna Of Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Ray-finned Fish Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...

Taxa Named By John Richardson (naturalist)
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
