Apistinae
Apistinae, the wasp scorpionfishes, is a subfamily of Venom, venomous, marine ray-finned fishes belonging to the Family (biology), family Scorpaenidae, the scorpionfishes and related species. These fishes are native to the Indian Ocean and the western Pacific Ocean. Taxonomy Apistinae, or Apsitidae, was first formally recognised as a taxonomic grouping in 1859 by the American ichthyologist Theodore Gill. The 5th edition of Fishes of the World treats this as a subfamily of the scorpionfish Family (biology), family Scorpaenidae, although other authorities treat it as a valid family, the Apistidae. The name of the subfamily is based on the genus name ''Apistus'', which means "untrustworthy" or "perfidious", a name Cuvier explained as being due to the long and mobile spines around the eyes, which he described as “very offensive weapons that these fish use when you least expect it”. A recent study placed the wasp scorpionfishes into an expanded stonefish clade (Synanceiidae) bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gerlof Fokko Mees
Gerlof Fokko Mees (16 June 1926 – 31 March 2013) was a Dutch ichthyologist, ornithologist and museum curator. During 1946 to 1949 he took part as a conscript in the military actions to reestablish rule in the Dutch East Indies. During that time he became interested in the avian family Zosteropidae, comprising the white-eyes. Mees was born at Bloemendaal in the Netherlands. He was introduced to natural history by his parents and was introduced to birds by his uncle Jan Verwey. He attended the University of Leiden where he studied biology, obtaining his doctorate in 1956 with a break in Java as part of the Dutch forces during the Indonesian war of independence. It was during his time in Java that he took a special interest in white-eyes (''Zosterops'') and also an introduction to George Junge. During 1953-54 he visited Trinidad and Tobago and collected bird specimens. He was an assistant at the department birds of the Rijksmuseum van Natuurlijke Historie in Leiden from May 1955 t ...

Species
In biology, a species is the basic unit of 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 produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, 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 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 specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Papua
The Gulf of Papua is located in the southern coast region of New Guinea. It has a total surface area of . Geography Some of New Guinea's largest rivers, such as the Fly River, Turama River, Kikori River, Purari River, and Wawoi River flow into the gulf, making it a large delta. While the western coast is characterized by swampy tidal waterways, land to the east ending at Cape Possession is flat and sandy. The Papuan Gulf's central and eastern interior slowly rises to meet the mountainous Southern Highlands, and is covered in a variety of inland swamps and dense tropical hardwood forests. The western interior possess a large region of limestone karst. The dry season begins in October and extends to February, after which the wet season starts. The southern border of the gulf is defined as a line from the southwestern corner of the Fly River Delta in the west, to Cape Suckling 355 km east of this, which is 70 km northwest of Port Moresby. This encloses a sea are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, echinoderms, sp ...

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries 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 hypural plate. Simply put, this measurement excludes the length of the 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 bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic
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. ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 taxonomy (biology), 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 ...

Fish Described In 1964
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. Mos ...
