Periophthalmus Darwini
Darwin's mudskipper (''Periophthalmus darwini'') is a relatively newly discovered mudskipper in 2004, so little is known about it. It is a brackish water ray-finned fish found in Australia along mud banks never far from mangrove trees. It is in the goby family Gobiidae. It is named after Charles Darwin because the holotype was collected in Darwin Harbour. Its greatest distinguishing characteristic from other mudskippers is its greatly reduced first dorsal fin in both sexes. Description The Darwin's mudskipper has a body shape and dorsally pultruding eyes similar to other mudskippers. They have a maximum length of 4.6 cm. It has 5 – 7 dorsal spines, 10 – 12 dorsal rays, 1 anal spine, and 11 – 13 anal rays. Its greatest distinguishing characteristic from other mudskippers is its greatly reduced first dorsal fin in both sexes. Its coloration is modally with a background color of light brown. They typically have dark brown streaks on their heads. They usually have dark br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helen Kay Larson
Helen K. Larson is an ichthyologist who specialises in the fishes of the Indo-Pacific. In the 1960s and 1970s, she attended the University of Guam to study for her Bachelor's and master's degrees and while there she also worked in the local Marine Laboratory. While there she collected and described a new species of the dwarf goby from the genus '' Eviota'', '' Eviota pellucida'', the description being published in 1976 in the journal ''Copeia''. This was her first description of a new species. Her Masters was called ''Notes on the biology and comparative behaviour of ''Eviota zonura'' and ''Eviota smaragdus'' (Pisces:Gobiidae)''. She gained a PhD in Zoology from the University of Queensland and her thesis was ''A revision of the gobiid fish genus ''Mugilogobius'' (Teleostei: Gobioidei), and its systematic placement''. She moved from Guam in 1974 to work with Douglass F. Hoese at the Australian Museum in Sydney as a Technical Officer and in 1981 she took a position as Curat ...

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 ...

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Darwin, Northern Territory
Darwin ( ; Larrakia: ) is the capital city of the Northern Territory, Australia. With an estimated population of 147,255 as of 2019, the city contains the majority of the residents of the sparsely populated Northern Territory. It is the smallest, wettest, and most northerly of the Australian capital cities and serves as the Top End's regional centre. Darwin's proximity to Southeast Asia makes the city's location a key link between Australia and countries such as Indonesia and East Timor. The Stuart Highway begins in Darwin, extends southerly across central Australia through Tennant Creek and Alice Springs, concluding in Port Augusta, South Australia. The city is built upon a low bluff overlooking Darwin Harbour. Darwin's suburbs begin at Lee Point in the north and stretch to Berrimah in the east. The Stuart Highway extends to Darwin's eastern satellite city of Palmerston and its suburbs. The Darwin region, like much of the Top End, experiences a tropical climate with a wet a ...

''Periophthalmus'' is a genus of fish in the family Oxudercidae, native to coastal mangrove wood and shrubland in the Indo-Pacific region, except for ''P. barbarus'' from the Atlantic coast of Africa.

Fish Described In 2004
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 f ...

Taxa Named By Helen K
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 intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
