Holocentrus Rufus
The longspine squirrelfish (''Holocentrus rufus'') is a silvery red, sea fish with orange-gold body stripes. One of about 150 species of squirrelfish, their most distinguishing characteristics are their large eyes and the long third spine of the anal fin. It is often included in public aquarium displays. The length of the longspine squirrelfish is about 18 cm (7.8 inches). It lives in coral reefs in tropical and warm temperate seas and eats zoobenthos. It is territorial and uses sounds called "grunts" and "staccatos" to defend its crevice, warn of danger and, in groups, intimidate predators such as the moray eel. The longspine squirrelfish is edible and harvested on a small scale. Identification The body of the longspine squirrelfish is silvery red, with orange-gold body stripes. Its eyes are very large, which is characteristic of all squirrelfish. The rear dorsal fin is pronounced and sticks up. The anal fin has a strongly elongated third spine, from which this squirrelfis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocentridae
Holocentridae is a family of ray-finned fish, the only family of the order Holocentriformes. The members of the subfamily Holocentrinae are typically known as squirrelfish, while the members of Myripristinae typically are known as soldierfish.Lieske, Ewald, & Robert Myers. 1999. ''Coral Reef Fishes - Caribbean, Indian Ocean, and Pacific Ocean including the Red Sea.'' 2nd edition. In Hawaii, they are known by the Japanese name ''mempachi/menpachi'' (メンパチ) or the Hawaiian ''ʻūʻū''. They are found in tropical parts of the Indian, Pacific and Atlantic Oceans, with the greatest species richness near reefs in the Indo-Pacific. Most are found at depths from the shoreline to , but some, notably the members of the genus ''Ostichthys'', are generally found far deeper. Being largely or entirely nocturnal, they have relatively large eyes. During the day, they typically remain hidden in crevices, caves, or under ledges. Red and silvery colours dominate. The preopercle spines ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squirrelfish
Holocentrinae is a subfamily of Holocentridae containing 40 recognized species and one proposed species. Its members are typically known as squirrelfish and all are nocturnal. All three genera in the subfamily are found in the Atlantic and ''Holocentrus'' is restricted to this ocean. Most species in genera ''Neoniphon'' and ''Sargocentron'' are from the Indo-Pacific region and several of these occur in the Indian Ocean west of the southern tip of India.Randal, J.E. and Heemstra, P.C. 1985"A review of the squirrelfishes of the subfamily Holocentrinae from the Western Indian Ocean and Red Sea" ''Ichthyological Bulletin of the J.L.B. Smith Institute of Ichthyology''; No. 49. J.L.B. Smith Institute of Ichthyology, Rhodes University.

Giovanni Antonio Scopoli
Giovanni Antonio Scopoli (sometimes Latinized as Johannes Antonius Scopolius) (3 June 1723 – 8 May 1788) was an Italian physician and naturalist. His biographer Otto Guglia named him the "first anational European" and the "Linnaeus of the Austrian Empire". Biography Scopoli was born at Cavalese in the Val di Fiemme, belonging to the Bishopric of Trent (today's Trentino), son of Francesco Antonio, military commissioner, and Claudia Caterina Gramola (1699-1791), painter from a patrician family from Trentino. He obtained a degree in medicine at University of Innsbruck, and practiced as a doctor in Cavalese and Venice.Newton, Alfred 1881. ''Scopoli's ornithological papers.'' The Willoughby SocietyScanned version/ref> Much of his time was spent in the Alps, collecting plants and insects, of which he made outstanding collections. He spent two years as private secretary to the bishop of Seckau, and then was appointed in 1754 as physician of the mercury mines in Idrija, a small to ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth#Surface, Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of Earth, the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North America, North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8th paralle ...

Pehr Osbeck
Pehr Osbeck (1723 – 23 December 1805) was a Swedish explorer, naturalist and an apostle of Carl Linnaeus. He was born in the parish of Hålanda on Västergötland and studied at Uppsala with Carolus Linnaeus. Naturalist in Canton In 1750–1752 he travelled as chaplain on the ship ''Prins Carl'' to Asia where he spent four months studying the flora, fauna, and people of the Canton region of China. He returned home just in time to contribute more than 600 species of plant to Linnaeus' ''Species Plantarum'', published in 1753. In 1757 he published the journal of his voyage to China, ''Dagbok öfwer en ostindisk Resa åren 1750, 1751, 1752'', which was translated into German in 1762 and English in 1771. In 1758, he was elected a member of the Royal Swedish Academy of Sciences. Later career He ended his career as the parish priest of Våxtorp and Hasslöv in Halland, where he died in 1805. Collections His large collections are preserved in Sweden and the UK. He is commemor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Julius Walbaum
Johann Julius Walbaum (30 June 1724 – 21 August 1799) was a German physician, naturalist and fauna taxonomist. Works As an ichthyologist, he was the first to describe many previously unknown fish species from remote parts of the globe, such as the Great Barracuda (''Sphyraena barracuda''), the Chum salmon (''Oncorhynchus keta'') from the Kamchatka River in Siberia, and the curimatá-pacú ('' Prochilodus marggravii'') from the São Francisco River in Brazil. He was also the first to observe gloves as a preventative against infection in medical surgery. In 1758, the gloves he observed were made from the cecum of the sheep, rather than rubber, which had not yet been discovered. Legacy The Natural History Museum in Lübeck, opened in 1893, was based on Walbaum's extensive scientific collection, which was lost during the Second World War World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945.

Ray-finned Fish Genera
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from '' Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Act ...
