Scarus Altipinnis
''Scarus altipinnis'', the filament-finned parrotfish, high-fin parrotfish or mini-fin parrotfish, is a species of marine ray-finned fish, a parrotfish from the family Scaridae. It occurs in the tropical and subtropical Western Pacific Ocean. Description ''Scarus altipinnis'' is distinguished from its congeners in the genus ''Scarus'' by the possession of a slightly elongated middle ray in the dorsal fin of the terminal phase males. These males are patterned with green towards the tail and have tow bluish-green bars on their chins and similar coloured spots and lines around the eye and operculum. They also have crescent-shaped tails which have slightly lengthened filaments in their centre. The females, the initial phase, are brownish with a scattering of white spots while the juveniles are striped or mottled with an obvious yellow head. The maximum total length attained is . Distribution ''Scarus altipinnis'' is found in the western Pacific Ocean from the Ryukyu Islands south to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franz Steindachner
Franz Steindachner (11 November 1834 in Vienna – 10 December 1919 in Vienna) was an Austrian Zoology, zoologist, ichthyologist, and herpetologist. He published over 200 papers on fishes and over 50 papers on reptiles and amphibians. Steindachner described hundreds of new species of fish and dozens of new amphibians and reptiles. At least seven species of reptile have been named after him. Work and career Being interested in natural history, Steindachner took up the study of fossil fishes on the recommendation of his friend Eduard Suess (1831–1914). In 1860 he was appointed to the position of director of the fish collection at the Naturhistorisches Museum, a position which had remained vacant since the death of Johann Jakob Heckel (1790–1857). (in German). Steindachner's reputation as an Ichthyology, ichthyologist grew, and in 1868 he was invited by Louis Agassiz (1807–1873) to accept a position at the Museum of Comparative Zoology at Harvard University. Steindachner took ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ducie Island
Ducie Island is an uninhabited atoll in the Pitcairn Islands. It lies east of Pitcairn Island, and east of Henderson Island, and has a total area of , which includes the lagoon. It is long, measured northeast to southwest, and about wide. The island is composed of four islets: Acadia, Pandora, Westward and Edwards. Despite its sparse vegetation, the atoll is known as the breeding ground of a number of bird species. More than 90% of the world population of Murphy's petrel nests on Ducie, while pairs of red-tailed tropicbirds and fairy terns make around 1% of the world population for each species. Ducie was first discovered in 1606 by Pedro Fernandes de Queiros, who named it ''Luna Puesta'', and rediscovered by Edward Edwards, captain of , who was sent in 1790 to capture the mutineers of . He named the island ''Ducie'' in honour of Francis Reynolds-Moreton, 3rd Baron Ducie. In 1867, it was claimed by the United States under the Guano Islands Act, but the United Kingdom a ...

Scarus
''Scarus'' is a genus of parrotfishes. With 52 currently recognised extant species,Froese, R. and D. Pauly, Eds''Scarus''.FishBase. 2013. it is by far the largest genus in this family. The vast majority are found at reefs in the Indo-Pacific, but a small number of species are found in the warmer parts of the eastern Pacific and the western Atlantic, with a single species, ''Scarus hoefleri'' in the eastern Atlantic. Most are very colourful, and have strikingly different initial (males and females) and terminal (males only) phases. Adults of most species reach maximum lengths of between , but the rainbow parrotfish (''Scarus guacamaia'') can grow to lengths of . Species There are currently 52 recognised species in this genus: *'' Scarus altipinnis'' (Steindachner, 1879) (filament-finned parrotfish) *'' Scarus arabicus'' (Steindachner, 1902) (Arabian parrotfish) *'' Scarus caudofasciatus'' ( Günther, 1862) (red-barred parrotfish) *'' Scarus chameleon'' Choat & Randall, 1986 (c ...

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Ichthyologist
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish ( Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha). According to FishBase, 33,400 species of fish had been described as of October 2016, with approximately 250 new species described each year. Etymology The word is derived from the Greek words ἰχθύς, ''ikhthus'', meaning "fish"; and λογία, ''logia'', meaning "to study". History The study of fish dates from the Upper Paleolithic Revolution (with the advent of "high culture"). The science of ichthyology was developed in several interconnecting epochs, each with various significant advancements. The study of fish receives its origins from humans' desire to feed, clothe, and equip themselves with useful implements. According to Michael Barton, a prominent ichthyologist and professor at Centre College, "the earliest ichthyologists were ''hunters and gatherers'' who had learned how to obtain the most usef ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commercial Fishing
Commercial fishing is the activity of catching fish and other seafood for commercial profit, mostly from wild fisheries. It provides a large quantity of food to many countries around the world, but those who practice it as an industry must often pursue fish far into the ocean under adverse conditions. Large-scale commercial fishing is also known as industrial fishing. The major fishing industries are not only owned by major corporations but by small families as well. In order to adapt to declining fish populations and increased demand, many commercial fishing operations have reduced the sustainability of their harvest by fishing further down the food chain. This raises concern for fishery managers and researchers, who highlight how further they say that for those reasons, the sustainability of the marine ecosystems could be in danger of collapsing. Commercial fishermen harvest a wide variety of animals. However, a very small number of species support the majority of the world ...

Spawn (biology)
Spawn is the Egg cell, eggs and Spermatozoa, sperm released or deposited into water by aquatic animals. As a verb, ''to spawn'' refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning. Most aquatic animals, except for aquatic mammals and marine reptile, reptiles, reproduce through the process of spawning. Spawn consists of the reproductive cells (gametes) of many aquatic animals, some of which will become fertilized and produce offspring. The process of spawning typically involves females releasing Ovum, ova (unfertilized eggs) into the water, often in large quantities, while males simultaneously or sequentially release spermatozoa (milt) to fertilize the eggs. Most fish reproduce by spawning, as do most other aquatic animals, including crustaceans such as crabs and shrimps, molluscs such as oysters and squid, echinoderms such as sea urchins and sea cucumbers, amphibians such as frogs and newts, aquatic insects such as mayflies and mos ...

Ovipary
Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes. In traditional usage, most insects (one being ''Culex pipiens'', or the common house mosquito), molluscs, and arachnids are also described as oviparous. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body. However, the biologist Thierry Lodé recently divided the traditional category of oviparous reproduction into two modes that he named ovuliparity and (true) oviparity respectively. He distinguished the two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Line Islands
The Line Islands, Teraina Islands or Equatorial Islands (in Gilbertese, ''Aono Raina'') are a chain of 11 atolls (with partly or fully enclosed lagoons) and coral islands (with a surrounding reef) in the central Pacific Ocean, south of the Hawaiian Islands. The island chain stretches northwest to southeast across , making it one of the longest island chains in the world. It lies at the geographic center of the Pacific Ocean (), near Starbuck Island. One of the atolls in the group, Kiritimati, has the largest land area of any atoll in the world. Of the 11 atolls, all of which were formed by volcanic activity, only the Kiritimati and Tabuaeran atolls and Teraina island have a permanent population (one of the reefs, Filippo Reef, is shown on some maps, but its existence is doubted). Eight of the atolls are parts of Kiribati. The remaining three—Jarvis Island, Kingman Reef (which is largely submerged), and Palmyra Atoll—are territories of the United States grouped with the United ...
