Pisces In The 10th Edition Of Systema Naturae
In the 10th edition of ''Systema Naturae'', Carl Linnaeus described the Pisces as: Always inhabiting the waters; are swift in their motion and voracious in their appetites. They breathe by means of gills, which are generally united by a bony arch; swim by means of radiate fins, and are mostly covered over with cartilaginous scales. Besides the parts they have in common with other animals, they are furnished with a nictitant membrane, and most of them with a swim-bladder, by the contraction or dilatation of which, they can raise or sink themselves in their element at pleasure. Linnaean Characteristics *Heart: 1 auricle, 1 ventricle. Cold, dark red blood *Gills: external *Jaw: incumbent *Penis: (usually) none *Eggs: without whites *Organs of Sense: tongue, nostrils?, eyes, ears *Covering: imbricate scales *Supports: fins. Swims in the Water & Smacks. Apodes ;''Muraena'' ( eels) *''Muraena helena'' – Mediterranean moray *''Muraena ophis'' – Spotted snake eel *''Muraena serp ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wolffish
Anarhichadidae, the wolffishes, sea wolves or wolf eels, is a family of marine ray finned fishes belonging to the order Scorpaeniformes. These are predatory, eel shaped fishes which are native to the cold waters of the Arctic, North Pacific and North Atlantic Oceans. Taxonomy Anarhichadidae was first proposed as a family in 1832 by the French zoologist Charles Lucien Bonaparte. The 5th edition of ''Fishes of the World'' classifies this family within the suborder Zoarcoidei, within the order Scorpaeniformes. Other authorities classify this family in the infraorder Zoarcales wihin the suborder Cottoidei of the Perciformes because removing the Scorpaeniformes from the Perciformes renders that taxon non monophyletic. Etymology Anarhichadidae is derived from the name of its type genus ''Anarhichas'' which is an Ancient Greek name for the Atlantic wolffish (''A. lupus'') and means "the climber", in turn derived from the Greek ''anarrhichesis'' which means "to climb or scramble up". ...

Uranoscopus Scaber
The Atlantic stargazer (''Uranoscopus scaber'') is a marine, subtropical fish of family Uranoscopidae. Its body is suited for living on the sea floor, and is one of few fish capable of bioelectrogenesis, or the ability to generate an electric charge. Distribution and habitat It is widespread along the Atlantic coast of Europe and Africa, is very common in the Mediterranean and Black Sea, and somewhat rare in the Bay of Biscay. It is a demersal fish, which lives in sandy or muddy sand sediments along the upper slope of the continental shelf, between depths of 14–400 meters. It is not an economically important fish, primarily caught as by-catch, but is ecologically important. Description Typical of stargazers, its body is somewhat dorso-ventrally flattened, lacks a swimbladder, and has been found as large as 35.0 centimeters in length, but is usually between 20 and 30 cm. Its head and jaws are rotated upward, and has very large eyes and mouth. Its body is brown in color ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stargazer (fish)
The stargazers are a family, Uranoscopidae, of perciform fish that have eyes on top of their heads (hence the name). The family includes about 51 species (one extinct) in eight genera, all marine and found worldwide in shallow and deep saltwaters. Description In addition to the top-mounted eyes, a stargazer also has a large, upward-facing mouth in a large head. Their usual habit is to bury themselves in sand, and leap upwards to ambush prey ( benthic fish and invertebrates) that pass overhead. Some species have a worm-shaped lure growing out of the floors of their mouths, which they can wiggle to attract prey's attention. Both the dorsal and anal fins are relatively long; some lack dorsal spines. Lengths range from 18 up to 90 cm, for the giant stargazer ''Kathetostoma giganteum''. Stargazers are venomous; they have two large venomous spines situated behind their opercles and above their pectoral fins. The species within the genera '' Astroscopus'' and ''Uranoscopus' ...

Bartail Flathead
The bartail flathead (''Platycephalus indicus''), also known as the Indian flathead, gobi or Indo-Pacific flathead, is a species of largely marine ray-finned fish belonging to the family Platycephalidae, the flatheads. This species is found in the Indian Ocean and the Western Pacific Ocean, and has invaded the eastern Mediterranean Sea. Taxonomy The bartail flathead was first formally described in 1758 as ''Callionymus indicus'' by Carl Linnaeus in the 10th edition of ''Systema Naturae'' with the type locality given as “Asia”. In 1795 the German physician and naturalist Marcus Elieser Bloch described ''Platycephalus spathula'' from Tranquebar in India creating the genus '' Platycephalus''. In 1917 David Starr Jordan and Barton Warren Evermann designated Bloch’s ''P. spathula'' as the type species of ''Platycephalus'', ''P. spathula'' is now considered to be a junior synonym of Linnaeus’s ''C. Indicus''. Species complex There are indications that ''Platycephalus ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
