Swallowtail Hawkfish
The swallowtail hawkfish ('' Cyprinocirrhites polyactis''), also known as the lyretail hawkfish, is a species of marine ray-finned fish, a hawkfish belonging to the family Cirrhitidae. It is found on to tropical reefs in the Indian Ocean and the western Pacific Ocean. This species grows to in total length. It is also found in the aquarium trade. This species is the only known member of its genus. Taxonomy The swallowtail hawkfish was first formally described in 1874 as ''Cirrhitichthys polyactis'' by the Dutch ichthyologist Pieter Bleeker with the type locality given as Ambon Island. In 1917 the Japanese ichthyologist Shigeho Tanaka described a new species, ''Cyprinocirrhites ui'', which he placed in a new monotypic genus although this was later considered to be a synonym of ''Cirrhitichthys polyactis'' the monotypic genus was retained. The genus name combines ''cyprinus'' meaning "carp" or "minnow", Tanaka did not explain why, and ''cirrhites'' and alternative spelling of ...

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616.

Melanesia
Melanesia (, ) is a subregion of Oceania in the southwestern Pacific Ocean. It extends from Indonesia's New Guinea in the west to Fiji in the east, and includes the Arafura Sea. The region includes the four independent countries of Fiji, Vanuatu, the Solomon Islands, and Papua New Guinea. It also includes the French oversea collectivity of New Caledonia, Indigenous Australians of the Torres Strait Islands and parts of Indonesia, most notably the provinces of Central Papua, Highland Papua, Papua, South Papua, Southwest Papua, and West Papua. Almost all of the region is in the Southern Hemisphere; only a few small islands that are not politically considered part of Oceania—specifically the northwestern islands of Western New Guinea—lie in the Northern Hemisphere. The name ''Melanesia'' (in French, ''Mélanésie'') was first used in 1832 by French navigator Jules Dumont d'Urville: he coined the terms ''Melanesia'' and '' Micronesia'' along the preexisting '' Polyne ...

Indo-Pacific
The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the seas connecting the two in the general area of Indonesia. It does not include the temperate and polar regions of the Indian and Pacific oceans, nor the Tropical Eastern Pacific, along the Pacific coast of the Americas, which is also a distinct marine realm. The term is especially useful in marine biology, ichthyology, and similar fields, since many marine habitats are continuously connected from Madagascar to Japan and Oceania, and a number of species occur over that range, but are not found in the Atlantic Ocean. The region has an exceptionally high species richness, with the world's highest species richness being found in at its heart in the Coral Triangle, and a remarkable gradient of decreasing species richness radiating outward in al ...

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 ...

Lunate
Lunate is a crescent or moon-shaped microlith. In the specialized terminology of lithic reduction, a lunate flake is a small, crescent-shaped flake removed from a stone tool during the process of pressure flaking. In the Natufian period, a lunate was a small crescent-shaped stone tool that was sometimes used to harvest grasses. In archaeology a lunate is a small stone artifact, that has a sharpened straight edge and a blunt crescent shaped back. The word originates from the Latin word lunatus which means to bend like a crescent, and from luna meaning moon in Latin. A lunate object can be typically used as a decorative piece or as a stone tool. Israeli lunate In the earlier findings of Epipaleolithic lunate in the Natufian, Harifian, and Negev Kebaran periods in Israel they were roughly 10–40 mm long and were formed on small blades or bladelets. While the later findings Natufian and Harifian range of lengths varied then from 9–17 mm. In the later period the luna ... [...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] |
Cirrhitus
''Cirrhitus'' is a genus of marine ray-finned fish, hawkfishes from the family Cirrhitidae. The species in this genus are found on tropical reefs worldwide. Taxonomy ''Cirrhites'' was first formally described as a genus in 1803 by the French naturalist Bernard Germain de Lacépède, Lacépède created it as a monotypic genus for his newly described species from Mauritius, ''Cirrhitus maculatus''. However, it was later shown that Lacépède's ''C. maculatus'' was synonymous with ''Labrus pinnulatus'' described in manuscript by the German naturalist and explorer Johann Reinhold Forster from Tahiti. Forster's was the basis of the description published in 1801 by Johann Gottlob Schneider in his and Marcus Elieser Bloch's ''Systema Ichthyologiae'', although ''Catalog of Fishes'' attributes the name to Forster. The name of this genus is dereived from ''cirrhus'' meaning a "lock of hair" or a "barbel", Lacépède did not explain what he feature the name alludes to. It may be allu ...
