Three-bearded Rockling
The three-bearded rockling (''Gaidropsarus vulgaris'') is found in European waters from the central Norwegian coast and the Faroe Islands, through the North Sea, and around the British Isles to the region around the western Mediterranean The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern .... They can grow to a maximum length of 60 cm (2 ft). Their coloration varies from dusky to pale, with large chocolate-brown spots on the head and body, and fin coloration varies with location. They also may have xanthochromism, which is colour condition characterized by overt of yellow-orange-red pigmentation, because of high levels of xanthophores in the skin. Three barbels, one on the bottom jaw and two on the snout, provide the fish with its common name. References * * Quigley, D. ...

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups within th ...

Hippolyte Cloquet
Hippolyte Cloquet (10 March 1787 – 3 March 1840) was a French physician and anatomist who was a native of Paris. He was the brother of surgeon Jules Germain Cloquet (1790–1883), and father to Ernest Cloquet (1818–1855), who was a personal physician to Mohammad Shah Qajar of Persia. He studied medicine in Paris, where he earned his doctorate in 1815. In 1823 he became a member of the '' Académie de Médecine''. Cloquet was a pioneer in the field of rhinology, and in 1821 published '' Osphrésiologie, ou traité des odeurs'', which was a comprehensive treatise that discussed olfaction, diseases of the nose, deviations of the septum, rhinoplasty, et al. He was also author of ''Traité d'anatomie descriptive'', an influential French text of anatomy that ran through six editions. The fourth edition of this work was translated into English by anatomist Robert Knox (1791–1862). Cloquet also made contributions in the field of zoology, his treatise ''Poissons et Reptiles'' w ...

Antoine Risso
Giuseppe Antonio Risso (8 April 1777 – 25 August 1845), called Antoine Risso, was a naturalist from Nice. Risso was born in the city of Nice in the Duchy of Savoy, and studied under Giovanni Battista Balbis. He published ' (1810), ' (1826) and ' (1818–1822). Risso's dolphin was named after him. He is denoted by the author abbreviation Risso when citing a botanical name; the same abbreviation is used for zoological names. Genera and species named after him * '' Rissoa'' : a genus of gastropods * '' Rissoella'' : a genus of gastropod * '' Rissoella'' : a genus of red algae * '' Electrona risso'' : a lanternfish *'' Polyacanthonotus rissoanus'' : smallmouth spiny eel Genera and species named by him He named 549 marine genera and species.

Faroe Islands
The Faroe Islands ( ) (alt. the Faroes) are an archipelago in the North Atlantic Ocean and an autonomous territory of the Danish Realm, Kingdom of Denmark. Located between Iceland, Norway, and the United Kingdom, the islands have a population of 54,609 and a land area of 1,393 km². The official language is Faroese language, Faroese, which is partially mutually intelligible with Icelandic language, Icelandic. The terrain is rugged, dominated by fjords and cliffs with sparse vegetation and few trees. As a result of its proximity to the Arctic Circle, the islands experience perpetual Twilight, civil twilight during summer nights and very short winter days; nevertheless, they experience a Oceanic climate#Subpolar variety (Cfc, Cwc), subpolar oceanic climate and mild temperatures year-round due to the Gulf Stream. The capital, Tórshavn, receives the fewest recorded hours of sunshine of any city in the world at only 840 per year. Færeyinga saga, Færeyinga Saga and the writin ...

Mediterranean
The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The sea was an important rout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbels
In fish anatomy and turtle anatomy, a barbel is a slender, whisker like sensory organ near the mouth (sometimes called whiskers or tendrils). Fish that have barbels include the catfish, the carp, the goatfish, the hagfish, the sturgeon, the zebrafish, the black dragonfish and some species of shark such as the sawshark. Barbels house the taste buds of such fish and are used to search for food in murky water. The word ''barbel'' comes from Latin ''barbula'' 'little beard'. Barbels are sometimes erroneously referred to as '' barbs'', which are found in bird feathers for flight. Barbels may be located in a variety of locations on the head of a fish. "Maxillary barbels" refers to barbels on either side of the mouth. Barbels may also be nasal, extending from the nostrils. Also, barbels are often mandibular or mental, being located on the chin. In fish, barbels can take the form of small, fleshy protrusions or long, cylindrical shaped extensions of the head of a fish. The cylindri ...

Fauna Of The British Isles
The island of Great Britain, along with the rest of the archipelago known as the British Isles, has a largely temperate climate. It contains a relatively small fraction of the world's wildlife. The biota was severely diminished in the last ice age, and shortly (in geological terms) thereafter was separated from the continent by the English Channel's formation. Since then, humans have hunted the most dangerous forms (the wolf, the brown bear and the wild boar) to extinction, though domesticated forms such as the dog and the pig remain. The wild boar has subsequently been reintroduced as a meat animal. Overview In most of Great Britain there is a temperate climate, with high levels of precipitation and medium levels of sunlight. Further northwards, the climate becomes colder and coniferous forests appear, replacing the largely deciduous forests of the south. There are a few variations in the generally temperate British climate, with some areas of subarctic conditions, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1824
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish w ...
