Liocranium
''Liocranium'' is a small genus of marine ray-finned fishes, waspfishes belonging to the subfamily Tetraroginae, which is classified as part of the family Scorpaenidae, the scorpionfishes and their relatives. The fishes in this genus are found in the eastern Indian Ocean and the western Pacific Ocean. Taxonomy ''Liocranium'' was first described as a genus in 1903 by the Australian ichthyologist James Douglas Ogilby when he described a new species of waspfish from Queensland he called ''Liocranium praepositum'' and placed in a new monotypic genus. In 1927 Gilbert Percy Whitley proposed the name ''Abcichthys'' for this genus as he considered that ''Liocranium'' was preoccupied by the spider genus ''Liocranum'', however, there is enough difference between these two names to regard ''Liocranium'' as valid and Whitley's name is treated as a synomym. In 1964 Mees classified ''Paracentropogon pleurostigma'', which had been described by Weber from New Guinea, as a subspecies of ' ...

Tetraroginae
Tetraroginae is a subfamily of marine ray-finned fishes, commonly known as waspfishes or sailback scorpionfishes, belonging to the family Scorpaenidae, the scorpionfishes and their relatives. These fishes are native to the Indian Ocean and the West Pacific. As their name suggests, waspfishes are often venomous; having poison glands on their spines. They are bottom-dwelling fish, living at depths to . These creatures usually live in hiding places on the sea bottom. Taxonomy and etymology Tetraroginae, or Tetrarogidae, was first formally recognised as a taxonomic grouping in 1949 by the South African ichthyologist J.L.B. Smith. The 5th edition of Fishes of the World treats this as a subfamily of the scorpionfish family Scorpaenidae, however other authorities treat it as a valid family, the Tetrarogidae. A recent study placed the waspfishes into an expanded stonefish clade, within the family Synanceiidae, because all of these fish have a lachrymal sabre that can project a switch ...

James Douglas Ogilby
James Douglas Ogilby (16 February 1853 – 11 August 1925) was an Australian ichthyologist and herpetologist. Ogilby was born in Belfast, Ireland, and was the son of zoologist William Ogilby and his wife Adelaide, née Douglas. He received his education at Winchester College, England, and Trinity College, Dublin. Ogilby worked for the British Museum before joining the Australian Museum in Sydney. After being let go for drunkenness in 1890, he picked up contract work before joining the Queensland Museum in Brisbane circa 1903. He was the author of numerous scientific papers on reptiles, and he described a new species of turtle and several new species of lizards. Ogilby died on 11 August 1925 and was buried at Toowong Cemetery Toowong Cemetery is a heritage-listed cemetery on the corner of Frederick Street and Mt Coot-tha Road, Toowong, City of Brisbane, Queensland, Australia. It was established in 1866 and formally opened in 1875. It is Queensland's largest cemet .. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerlof 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 to J ...

Standard Length
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.

Cycloid Scale
A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages. The term ''scale'' derives from the Old French , meaning a shell pod or husk. Scales vary enormously in size, shape, structure, and extent, ranging from strong and rigid armour plates in fishes such as shrimpfishes and boxfishes, to microscopic or absent in fishes such as eels and anglerfishes. The morphology of a scale can be used to identify the species of fish it came from. Scales originated within the jawless ostracoderms, ancestors to all jawed fishes today. Most bony fishes are covered with the cycloid scales of salmon and carp, or the ctenoid scales of perch, or the ganoid scales of sturgeons and gars. Cartilaginous fishes (sharks and rays) are covered with placoid scales. Some specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palatine Bone
In anatomy, the palatine bones () are two irregular bones of the facial skeleton in many animal species, located above the uvula in the throat. Together with the maxillae, they comprise the hard palate. (''Palate'' is derived from the Latin ''palatum''.) Structure The palatine bones are situated at the back of the nasal cavity between the maxilla and the pterygoid process of the sphenoid bone. They contribute to the walls of three cavities: the floor and lateral walls of the nasal cavity, the roof of the mouth, and the floor of the orbits. They help to form the pterygopalatine and pterygoid fossae, and the inferior orbital fissures. Each palatine bone somewhat resembles the letter L, and consists of a horizontal plate, a perpendicular plate, and three projecting processes—the pyramidal process, which is directed backward and lateral from the junction of the two parts, and the orbital and sphenoidal processes, which surmount the vertical part, and are separated by a dee ...

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 lu ...

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.
