Illicium (fish Anatomy)
The anglerfish are ray-finned fish in the order Lophiiformes (). Both the order's common name, common and scientific name comes from the characteristic mode of predation, in which a modified dorsal Fish fin#Ray-fins, fin ray acts as a Aggressive mimicry#Food as an attractant, lure for prey (akin to a human Angling, angler, and likened to a crest or "''wikt:Lophius, lophos''"). The modified fin ray, with the very tip being the Esca (fish anatomy), esca and the length of the structure the Illicium (fish anatomy), illicium, is adapted to attract specific prey items across the families of anglerfish by using different luring methods. Anglerfish occur worldwide. The majority are bottom-dwellers, being demersal fish, while the aberrant deep-sea anglerfish are Pelagic fish, pelagic, (mostly) living high in the water column. Some live in the Deep-sea fish, deep sea (such as the deep-sea anglerfish and sea toads), while others live in Shallow water marine environment, shallower waters, s ...

Lophiiformes
The anglerfish are ray-finned fish in the order Lophiiformes (). Both the order's common and scientific name comes from the characteristic mode of predation, in which a modified dorsal fin ray acts as a lure for prey (akin to a human angler, and likened to a crest or "'' lophos''"). The modified fin ray, with the very tip being the esca and the length of the structure the illicium, is adapted to attract specific prey items across the families of anglerfish by using different luring methods. Anglerfish occur worldwide. The majority are bottom-dwellers, being demersal fish, while the aberrant deep-sea anglerfish are pelagic, (mostly) living high in the water column. Some live in the deep sea (such as the deep-sea anglerfish and sea toads), while others live in shallower waters, such as the frogfishes and some batfishes. Anglerfish are notable for their sexual dimorphism, which is sometimes extremely pronounced; the males may be several orders of magnitude smaller in mass ...

Antennarioidei
Antennarioidei is a suborder of marine ray-finned fishes belonging to the order Lophiiformes, the anglerfishes. Taxonomy Antennarioidei was first proposed as a taxonomic grouping in 1912 by the English ichthyologist Charles Tate Regan. The 5th edition of ''Fishes of the World'' classifies this taxon as one of the five suborders in the order Lophiiformes. It and the suborders Chaunacoidei, Ogcocephaloidei, and Ceratioidei, are more derived than their basal sister group the Lophioidei. In some phylogenies the suborder Antennarioidei is the most basal of the Lophiiformes suborders other than Lophioidei. The relationships of the suborders within Lophiiformes as set out in Pietsch and Grobecker's 1987 ''Frogfishes of the world: systematics, zoogeography, and behavioral ecology'' is shown below. Etymology Antennarioidei is derived from ''Antennarius'', the type genus of the family Antennaridae. ''Antennarius'' suffixes ''-ius'' to antenna, an allusion to first dorsal spine be ...

Halieutaea Stellata
The starry handfish (''Halieutaea stellata''), starry seabat or minipizza batfish, is species of marine ray-finned fish belonging to the family Ogcocephalidae, the deep-sea batfishes or seabats. This fish is found on the continental shelves of the Indo-Pacific oceans at depths of between 50 and 400 m. They are up to 30 cm long. Taxonomy The starry handfish was first formally described as ''Lophius stellatus'' in 1797 by the Norwegian zoologist Martin Vahl with its type locality given as China. In 1827 Achille Valenciennes classified ''L. stellatus'' in the new monospecific genus ''Halieutaea'', although he did not name its author. The genus ''Halieutaea'' is the sister group to the other two clades, the Indo-Pacific clade and the Eastern Pacific and Western Atlantic clade, of the family Ogcocephalidae. The family Ogcocephalidae is classified in the monotypic suborder Ogcocephaloidei within the order Lophiiformes, the anglerfishes in the 5th edition of ''Fishes of the Worl ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

August Brauer
August Bernhard Brauer (3 April 186310 September 1917) was a German zoologist. Brauer was born in Oldenburg. He studied natural sciences at the Universities of Bonn, Berlin and Freiburg, obtaining his doctorate in 1895 with a thesis on the ciliate- ''Bursaria truncatella'' titled ''Bursaria truncatella unter Berücksichtigung anderer Heterotrichen und der Vorticellinen''. In 1892 he received his habilitation at the University of Marburg, where he subsequently worked as a lecturer. In 1894–95 he conducted scientific studies in the Seychelles. Along with other scientists, he participated in the " 1898–99 German Deep-Sea Expedition" aboard the steamer ''Valdivia'' under the leadership of Carl Chun (1852–1914). In 1906 he was named director of the Berlin Zoological Museum (nowadays Berlin's Natural History Museum), and later in his career he attained the title of "full professor". Brauer distinguished himself in the field of deep-sea ichthyology, based largely on his experien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Operculum (fish)
The operculum is a series of bones found in bony fish and chimaeras that serves as a facial support structure and a protective covering for the gills; it is also used for respiration and feeding. Anatomy The opercular series contains four bone segments known as the preoperculum, suboperculum, interoperculum and operculum. The preoperculum is a crescent-shaped structure that has a series of ridges directed posterodorsally to the organism’s canal pores. The preoperculum can be located through an exposed condyle that is present immediately under its ventral margin; it also borders the operculum, suboperculum, and interoperculum posteriorly. The suboperculum is rectangular in shape in most bony fish and is located ventral to the preoperculum and operculum components. It is the thinnest bone segment out of the opercular series and is located directly above the gills. The interoperculum is triangular shaped and borders the suboperculum posterodorsally and the preoperculum anterodo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batoidea
Batomorphi is a Division (taxonomy), division of Chondrichthyes, cartilaginous fishes, commonly known as rays, this taxon is also known as the Order (biology), superorder Batoidea, but the 5th edition of ''Fishes of the World'' classifies it as the division Batomorphi. They and their close relatives, the sharks, compose the subclass Elasmobranchii. Rays are the largest group of cartilaginous fishes, with well over 600 species in 26 families. Rays are distinguished by their flattened bodies, enlarged pectoral fins that are fused to the head, and gill slits that are placed on their ventral surfaces. Anatomy Batomorphs are flat-bodied, and, like sharks, are cartilaginous fish, meaning they have a boneless skeleton made of a tough, elastic cartilage. Most batomorphs have five ventral slot-like body openings called gill slits that lead from the gills, but the Hexatrygonidae have six. Batomorph gill slits lie under the pectoral fins on the underside, whereas a shark's are on the sides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
