Gobiesocidae
Clingfishes are fishes of the family Gobiesocidae, the only family in the order Gobiesociformes. These fairly small to very small fishes are widespread in tropical and temperate regions, mostly near the coast, but a few species in deeper seas or fresh water. Most species shelter in shallow reefs or seagrass beds, clinging to rocks, algae and seagrass leaves with their sucking disc, a structure on their chest. They are generally too small to be of interest to fisheries, although the relatively large '' Sicyases sanguineus'' regularly is caught as a food fish, and some of the other species occasionally appear in the marine aquarium trade. Distribution and habitat Clingfishes are primarily found near the shore in the Atlantic, Indian and Pacific Oceans, including marginal seas such as the Mediterranean, Gulf of Mexico, Caribbean and Gulf of California. The greatest species richness is in tropical and warm temperate regions, but the range of a few extends into colder waters, lik ...

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papua New Guinea
Papua New Guinea (abbreviated PNG; , ; tpi, Papua Niugini; ho, Papua Niu Gini), officially the Independent State of Papua New Guinea ( tpi, Independen Stet bilong Papua Niugini; ho, Independen Stet bilong Papua Niu Gini), is a country in Oceania that comprises the eastern half of the island of New Guinea and its offshore islands in Melanesia (a region of the southwestern Pacific Ocean north of Australia). Its capital, located along its southeastern coast, is Port Moresby. The country is the world's third largest island country, with an area of . At the national level, after being ruled by three external powers since 1884, including nearly 60 years of Australian administration starting during World War I, Papua New Guinea established its sovereignty in 1975. It became an independent Commonwealth realm in 1975 with Elizabeth II as its queen. It also became a member of the Commonwealth of Nations in its own right. There are 839 known languages of Papua New Guinea, on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madang Lagoon
Madang (old German name: ''Friedrich-Wilhelmshafen'') is the capital of Madang Province and is a town with a population of 27,420 (in 2005) on the north coast of Papua New Guinea. It was first settled by the Germans in the 19th century. History Russian biologist Nicholai Miklukho-Maklai was probably the first European to visit the area. In 1871 he stayed at Astrolabe Bay south of present-day Madang for 15 months. He had a good relationship with the local communities before leaving, suffering from malaria. In April 1884 an expedition by the German New Guinea Company led by Otto Finsch and Eduard Dallmann arrived and named the landing point "Friedrich Wilhelmshafen"; however, they felt that the area was unsuitable for a settlement. A subsequent survey in 1888 mentioned good soil conditions that would make a coffee plantation possible. In the summer of 1891 a station was built and by September 1892 was the seat of the provincial administration; however, the Imperial Government ...

Genus (biology)
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly ...

Oxycomanthus Bennetti
''Oxycomanthus bennetti'', the Bennett's feather star, is a species of crinoid belonging to the family Comatulidae. It is found in shallow water in the Indo-Pacific between northern Australia and southeast Asia. Description ''Oxycomanthus bennetti'' is one of the larger species of Comatulidae, growing up to 30 cm. It is a filter-feeder, meaning it does not hunt down food, it captures food suspended in the water column to eat. It does this with 31–120 feathery arms, usually held up into the water in order to trap food, feeding on detritus, phytoplankton and zooplankton. The arms have numerous finger-like appendages known as pinnules, in order to increase the surface area on which food can be trapped. The mouth is on the upper side of the large, thick body, otherwise known as the centrodorsal. Attached to the centrodorsal are many long, robust cirri (3-4.5 cm). These cirri are used by ''O. bennetti'' to hold on to substrate in the beginning portion of their lives, after the larva ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
