Peristrominous
The deceitful velvetfish (''Peristrominous dolosus'') is a species of marine ray-finned fish, a velvetfish, belonging to the Family (biology), family Aploactinidae. This species is endemic to the oceans around Australia. This species is the only known member of its genus. Taxonomy The deceitful velvetfish was first formally Species description, described in 1952 by the Australian ichthyologist and malacologist Gilbert Percy Whitley with the Type locality (biology), type locality given as Deception Bay, Queensland, Deception Bay in Queensland, Australia. When he described this new species Whitley classified it in the new monotypic genus ''Peristrominous''. This taxon is Taxonomy (biology), classified within the family Aploactinidae in the suborder Scorpaenoidei within the order Scorpaeniformes, although this family is also treated as a subfamily of the stonefish family Synanceiinae, Synanceiidae within the Scorpaenoidei, which in turn is treated as a Superfamily (biology), superfa ...

Velvetfish
Little velvetfishes or simply velvetfishes are a family, the Aploactinidae, of marine ray-finned fishes classified within the order Scorpaeniformes. They are small fish that have skin with a velvet texture. They live on the sea bottom close to the shore, at depths of up to . They are found in the Indo-Pacific region. Taxonomy Aploactinidae was first formally recognised as a family by the American ichthyologists David Starr Jordan and Edwin Chapin Starks in 1904.The 5th edition of ''Fishes of the World'' classifies the family within the suborder Scorpaenoidei which in turn is classified within the order Scorpaeniformes. Other authorities place the Scorpaenoidei within the Perciformes. The results of some studies suggest that the velvetfishes into an expanded stonefish clade, the family Synanceiidae because all of these fish have a curved sabre-like lacrimal spine that can project, using a switch-blade-like mechanism, out from underneath their eye. The name of the family is taken ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilbert Percy Whitley
Gilbert Percy Whitley (9 June 1903 – 18 July 1975) was a British-born Australian ichthyologist and malacologist who was Curator of Fishes at the Australian Museum in Sydney for about 40 years. He was born at Swaythling, Southampton, England, and was educated at King Edward VI School, Southampton and the Royal Naval College, Osborne. Whitley migrated with his family to Sydney in 1921 and he joined the staff of the Australian Museum in 1922 while studying zoology at Sydney Technical College and the University of Sydney. In 1925 he was formally appointed Ichthyologist (later Curator of Fishes) at the Museum, a position he held until retirement in 1964. During his term of office he doubled the size of the ichthyological collection to 37,000 specimens through many collecting expeditions. Whitley was also a major force in the Royal Zoological Society of New South Wales, of which he was made a Fellow in 1934 and where he served as president during 1940–41, 1959–60 and 1973� ...

Scorpaenoidei
Scorpaenoidei is a suborder of ray-finned fishes, part of the order Scorpaeniformes, that includes the scorpionfishes, lionfishes and velvetfishes. This suborder is at its most diverse in the Pacific and Indian Oceans but is also found in the Atlantic Ocean. Taxonomy Scorpaenoidei was first named as a suborder in 1899 by the American ichthyologist Samuel Garman as a suborder of the Perciformes. Some authorities still treat the suborder as being part of the Perciformes but the 5th Edition of ''Fishes of the World'' recognises the Scorpaeniformes as a valid order and places this suborder within it. The subfamilies of the family Scorpaenidae are treated as families by some authors. It has been argued by some authors that the suborder is paraphyletic and that a more correct classification is that the grouping, with some differences, be placed on the superfamily Scorpaenoidea. Families and subfamilies The suborder Scorpaenoidei is classified into families and subfamilies in the 5th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to ...

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans ( whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against r ...

Pelvic Fin
Pelvic fins or ventral fins are paired fins located on the ventral surface of fish. The paired pelvic fins are homologous to the hindlimbs of tetrapods. Structure and function Structure In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays ( lepidotrichia) are positioned distally from the radials. There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. Pelvic fin structures can be extremely specialized in actinopterygians. Gobiids and lumpsuckers modify their pelvic fins into a sucker disk that allow them to adhere to the substrate or climb structures, such as waterfalls. In priapiumfish, males have modified their pelvic structures into a spiny copulatory device that grasps the female during mating.

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 fo ...

Minous
''Minous'', is a genus of marine ray-finned fishes, it is the only genus in the tribe Minoini, one of the three tribes which are classified within the subfamily Synanceiinae within the family Scorpaenidae, the scorpionfishes and their relatives. They are commonly known as stingfishes. They are found in the Indo-West Pacific. Taxonomy ''Minous'' was first described as a genus by the French zoologist Georges Cuvier, in 1876 Pieter Bleeker designated ''Minous monodactylus'', which had originally been described as ''Scorpaena monodactyla'' by Bloch and Schneider in 1801, as its type species. It is the only genus in the tribe Minoini within the subfamily Synanceiinae of the family Scorpaenidae. However, some authorities classify this taxon as a subfamily, Minoinae,, Others include it within the subfamily Choridactylinae, within the family Synanceiidae. The genus name, ''Minous'', is a latinisation of ''woorah minooh'', the name that in 1803 the herpetologist Patrick Russell rep ...

Superfamily (biology)
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to identify a particular organism, it is usually not necessary to specify ranks other than these first two.

Synanceiinae
Synanceiinae is a subfamily of venomous ray-finned fishes, waspfishes, which is classified as part of the family Scorpaenidae, the scorpionfishes and their relatives. These fishes are found in the Indo-Pacific oceans. They are primarily marine, though some species are known to live in fresh or brackish waters. The various species of this family are known informally as stonefish, stinger, stingfish and ghouls. Its species are known to have the most potent neurotoxins of all the fish venoms, secreted from glands at the base of their needle-like dorsal fin spines. The vernacular name, stonefish, for some of these fishes derives from their behaviour of camouflaging as rocks. The type species of the family is the estuarine stonefish ('' Synanceia horrida''). Taxonomy Synanceiinae, or the family Synanceiidae, was first named and recognised as a grouping of related taxa by the English naturalist William John Swainson in 1839. The 5th edition of ''Fishes of the World'' treats this gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
