Gymnocaesio
The slender fusilier (''Gymnocaesio gymnoptera'') is a species of marine ray-finned fish, a fusilier belonging to the family Caesionidae. It is native to tropical reefs in the Indian Ocean and the western Pacific Ocean, It is of minor importance to local commercial fisheries. This species is the only known member of its genus. Taxonomy The slender fusilier was first formally described in 1856 as ''Caesio gymnopterus'' by the Dutch ichthyologist Pieter Bleeker with the type locality being given as Ternate. In 1876, Bleeker described a new genus, ''Gymnocaesio'' with ''C. gymnopterus'' as its type species by montypy, it is still the only species in that genus. The genus name is a compound of ''gymno'' meaning "naked" and ''caesio '' as in the related genus ''Caesio'' in which this species was originally placed. The specific name also uses ''gymno'' as a prefix for ''pterus'' which means fin, a reference to the lack of scales on the dorsal and anal fins, these are scaled in ...

Pterocaesio
''Pterocaesio'' is a genus of marine ray-finned fish, fuiliers belonging to the family Caesionidae. They are native to the Indian Ocean and the western Pacific Ocean. Taxonomy ''Pterocaesio'' was described as a genus in 1876 by the Dutch ichthyologist Pieter Bleeker with Franz Steindachner's ''Caesio multiradiatus'' as the type species. This taxon was subsequently shown to be a synonym of ''Caesio tile'' which had been described by Georges Cuvier in 1830. The generic name is a compound of ''ptero'' meaning "fin" and the genus name ''Caesio''. Bleeker did not give an explanation of his name but it may be because the type species ''P. tile'' has a higher number of rays in the dorsal fin. 21, compared to 13-18 in ''Caesio''. Three subgenera have been proposed for ''Pteroceasio''. Species Currently, 12 species in this genus are recognized, and have been divided into subgenera by some authorities as follows: * Subgenus ''Pterocaesio'' ** ''Pterocaesio tile'' (Cuvier, 1830) (dark-ban ...

Caesionidae
Caesionidae, the fusiliers, are a family of marine ray-finned fishes in the order Perciformes. The family includes about 23 species. They are related to the snappers, but adapted for feeding on plankton, rather than on larger prey. They are found at reefs in the Indo-Pacific and in the Red Sea. Taxonomy Caesionidae was named by the French zoologist Charles Lucien Bonaparte in 1831. The family takes its name from the genus ''Caesio'' which was named in 1801 by Bernard Germain de Lacépède, the name derived from ''caesius'' meaning “blue”, as the type species of ''Caesio'' is the blue and gold fusilier ('' Caesio caerulaurea''). They are sometimes divided into two subfamilies, the Caesioninae containing the genera ''Caesio'' and ''Pterocaesio'' and the monotypic genera ''Dipterygonotus'' and ''Gymoceasio'' in the Gymnocaesoninae. Some authorities place the fusiliers within the family Lutjanidae, the snappers, even going as far as placing the within the subfamily Lutjanin ...

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 for ...

Zooplankton
Zooplankton are the animal component of the planktonic community ("zoo" comes from the Greek word for ''animal''). Plankton are aquatic organisms that are unable to swim effectively against currents, and consequently drift or are carried along by currents in the ocean, or by currents in seas, lakes or rivers. Zooplankton can be contrasted with phytoplankton, which are the plant component of the plankton community ("phyto" comes from the Greek word for ''plant''). Zooplankton are heterotrophic (other-feeding), whereas phytoplankton are autotrophic (self-feeding). This means zooplankton cannot manufacture their own food but must eat other plants or animals instead — in particular they eat phytoplankton. Zooplankton are generally larger than phytoplankton, most are microscopic, but some (such as jellyfish) are macroscopic and can be seen with the naked eye. Many protozoans (single-celled protists that prey on other microscopic life) are zooplankton, including zooflagellates, fo ...

Mascarenes
The Mascarene Islands (, ) or Mascarenes or Mascarenhas Archipelago is a group of islands in the Indian Ocean east of Madagascar consisting of the islands belonging to the Republic of Mauritius as well as the French department of Réunion. Their name derives from the Portuguese navigator Pedro Mascarenhas, who first visited them in April 1512. The islands share a common geologic origin in the volcanism of the Réunion hotspot beneath the Mascarene Plateau and form a distinct ecoregion with a unique flora and fauna. Geography The archipelago comprises three large islands, Mauritius, Réunion, and Rodrigues, plus a number of volcanic remnants in the tropics of the southwestern Indian Ocean, generally between 700 and 1500 kilometres east of Madagascar. The terrain includes a variety of reefs, atolls, and small islands. They present various topographical and edaphic regions. On the largest islands these gave rise to unusual biodiversity. The climate is oceanic and tropical. Maurit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.

Caudal 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 ...

Lateral Line
The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these signals into electrical impulses via excitatory synapses. Lateral lines serve an important role in schooling behavior, predation, and orientation. Fish can use their lateral line system to follow the vortices produced by fleeing prey. Lateral lines are usually visible as faint lines of pores running lengthwise down each side, from the vicinity of the gill covers to the base of the tail. In some species, the receptive organs of the lateral line have been modified to function as electroreceptors, which are organs used to detect electrical impulses, and as such, these systems remain closely linked. Most amphibian larvae and some fully aquatic adult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
