Apistinae
Apistinae, the wasp scorpionfishes, is a subfamily of venomous, marine ray-finned fishes belonging to the 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 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) because all of these fish have a lachrymal saber ...

Gerlof Fokko Mees
Gerlof Fokko Mees (16 June 1926 – 31 March 2013) was a Dutch ichthyology, ichthyologist, ornithology, 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 i ...

Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...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 possesses 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, ...

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery 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. 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 (shark Sharks are a group of elasmobranch cartilaginous fish characterized by ...

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. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Fish Described In 1964
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...
