Cepola Schlegelii
''Cepola schlegelii'' i is a species of marine ray-finned fish belonging to the family Cepolidae, the bandfishes. It is found in the Indo-West Pacific region. Taxonomy ''Cepola schlegelii'' was first formally described in 1854 by the Dutch medical doctor, ichthyologist, and herpetologist Pieter Bleeker with the type locality given as Kaminoseki in Japan. The specific name honours the German ornithologist and herpetologist Hermann Schlegel. Description ''Cepola schlegelii'' is an elongated fish with the rearmost soft rays of both the elongated dorsal and anal fins connected to its lanceolate caudal fin by a membrane to form a continuous fin. The dorsal fin has 68-70 soft rays while the anal fin has 60-64. The pectoral fin has 19 fin rays There are no spines on the edge of the preoperculum and the cheeks are scaleless. This species attains a maximum total length of . The main colour of the body is red, with a black spot in the membranes of the jaw. The cheek, operculum and ...

Pieter Bleeker
Pieter Bleeker (10 July 1819 – 24 January 1878) was a Dutch medical doctor, ichthyologist, and herpetologist. He was famous for the ''Atlas Ichthyologique des Indes Orientales Néêrlandaises'', his monumental work on the fishes of East Asia published between 1862 and 1877. Life and work Bleeker was born on 10 July 1819 in Zaandam. He was employed as a medical officer in the Royal Netherlands East Indies Army from 1842 to 1860, (in French). stationed in the Dutch East Indies (now Indonesia). During that time, he did most of his ichthyology work, besides his duties in the army. He acquired many of his specimens from local fishermen, but he also built up an extended network of contacts who would send him specimens from various government outposts throughout the islands. During his time in Indonesia, he collected well over 12,000 specimens, many of which currently reside at the Naturalis Biodiversity Center in Leiden. Bleeker corresponded with Auguste Duméril of Paris. His wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 rollin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cepola
''Cepola'' is a genus of marine ray-finned fishes belonging to the bandfish family, Cepolidae. The name red bandfish is applied to all members of this genus, but particularly ''C. macrophthalma'', and generally not ''C. australis'', which is also known as the Australian bandfish. Taxonomy ''Cepola'' was first formally described as a genus in 1764 by Carolus Linnaeus with ''Ophidion macrophthalmum'' as the type species by monotypy. The generic name ''Cepola'' means "little onion", Linnaeus did not explain why he chose this name. It is likely derived from ''cepollam'' or ''cepulam'', which in 1686 was said by Francis Willughby to be local names among Roman fishermen for the similar "''Fierasfer"'', a pearlfish, to which Linnaeus believed ''Cepola macrophthalma'' was related. As well as this, in 1872 Giovanni Canestrini reported that in Naples the common name for ''C. macropthalma'' is ''Pesce cipolia'' meaning “onion fish”. Species There are currently five recognized species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northwest Shelf
The Northwest Shelf Province, also known as Exmouth to Broome, is a biogeographic region of Australia's continental shelf. Geography The Northwest Shelf Province includes the coastal waters and continental shelf of north-western Western Australia between North West Cape and Cape Leveque. It has an area of 238,759 km2, extending from the shore to 200 m depth. It varies in width from about 50 km at Exmouth Gulf to more than 250 km off Cape Leveque. The Northwest Shelf Province adjoins the Central Western Shelf Transition or Ningaloo region on the southwest. The Northwest Shelf Transition lies east of Cape Leveque. To the north the continental slope descends towards the Indian Ocean's abyssal plain. Oceanography The waters are tropical. Surface waters are derived from the Indonesian Throughflow, and circulate through the province via branches of the South Equatorial and Eastern Gyral currents. Tidal ranges are generally high. The Northwest Coast, including th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Carpentaria
The Gulf of Carpentaria (, ) is a large, shallow sea enclosed on three sides by northern Australia and bounded on the north by the eastern Arafura Sea (the body of water that lies between Australia and New Guinea). The northern boundary is generally defined as a line from Slade Point, Queensland (the northwestern corner of Cape York Peninsula) in the northeast, to Cape Arnhem on the Gove Peninsula, Northern Territory (the easternmost point of Arnhem Land) in the west. At its mouth, the Gulf is wide, and further south, . The north-south length exceeds . It covers a water area of about . The general depth is between and does not exceed . The tidal range in the Gulf of Carpentaria is between . The Gulf and adjacent Sahul Shelf were dry land at the peak of the last ice age 18,000 years ago when global sea level was around below its present position. At that time a large, shallow lake occupied the centre of what is now the Gulf. The Gulf hosts a submerged coral reef provinc ...

Total 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.

Pectoral 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 ...
