Lepadogaster Lepadogaster
The shore clingfish (''Lepadogaster lepadogaster'') is a clingfish of the family Gobiesocidae. It is found in the Mediterranean Sea and adjacent Atlantic Ocean north to Galicia, Spain. Description Distribution Occurs in the eastern Atlantic from Galicia, Spain to the Mediterranean, between latitudes 43.8° N and 30° N. Habitat and biology ''L. lepadogaster'' often inhabits underwater boulder fields consisting of smooth rocks and large pebbles. Its length is up to 65 mm. ''L. lepadogaster'' is also classified as a cryptobenthic fish. Cryptobenthic simply means that the fish is both behaviorally and visually cryptic. The term is also used mainly to describe adult fish of a certain size, roughly around 5 cm in length. The clingfish gets its name from the ability of the fish to attach itself to the rock walls of the ocean shore. It does this by having pelvic fins that have been adapted to form suckers. These suckers keep the clingfish strongly attached to the rocky sur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pierre Joseph Bonnaterre
Abbé Pierre Joseph Bonnaterre (1752, Aveyron – 20 September 1804, Saint-Geniez-d'Olt) was a French zoology, zoologist who contributed sections on cetaceans, mammals, birds, reptiles, amphibians, fish, and insects to the ''Tableau encyclopédique et méthodique''. He is also notable as the first scientist to study the feral child Victor of Aveyron. Bonnaterre is credited with identifying about 25 new species of fish, and assembled illustrations of about 400 in his encyclopedia work. He was the first scientist to study Victor, the wild child of Aveyron, whose life inspired François Truffaut for his film ''The Wild Child''.

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] [Amazon] |
Fish Of Europe
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 fis ...

Lepadogaster
''Lepadogaster'' is a genus of clingfishes native to the eastern Atlantic Ocean extending into the Mediterranean Sea. ''Lepadogaster'' belongs to class Actinopterygii. This means that they share many of the same characteristics as eels, ray-finned fish, and sea horses to name a few. The main characteristic of all of them though is having fin rays. These fin rays are made of webbed skin and are attached to portions of the body that connect fins to the bones. ''Lepadogaster'' species have a distinct difference in the formation of their dorsal and anal fins. While most other ray-finned fish spines, branched fin-rays, and middle radials, ''Lepadogaster'' species do not have these. Instead, they have cartilage in place of the mentioned features. These clingfish are mainly found near the rocky coasts and inside intertidal zones. ''Lepadogaster'' is known mostly as a clingfish, meaning that it spends most of its time attached to the surface of rocks. ''Lepadogaster'' species normally liv ...

Detritus
In biology, detritus ( or ) is organic matter made up of the decomposition, decomposing remains of organisms and plants, and also of feces. Detritus usually hosts communities of microorganisms that colonize and decomposition, decompose (Remineralisation, remineralise) it. Such microorganisms may be decomposers, detritivores, or coprophages. In terrestrial ecosystems detritus is present as plant litter and other organic matter that is intermixed with soil, known as soil organic matter. The detritus of aquatic ecosystems is organic substances suspended in the water and accumulated in depositions on the floor of the body of water; when this floor is a seabed, such a deposition is called marine snow. Theory The remains of decaying plants or animals, or their tissue parts, and feces gradually lose their form due to physical processes and the action of decomposers, including grazers, bacteria, and fungi. Decomposition, the process by which organic matter is decomposed, occurs in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Lepadogaster Purpurea
''Lepadogaster purpurea'', the Cornish sucker, is a species of clingfish from the family Gobiesocidae. It is found in the eastern North Atlantic Ocean and in the western Mediterranean Sea. Description ''Lepadogaster purpurea'' has a rather tadpole-like shape with a small body and a large flattened head with large mouth shaped like the bill of a duck-and a tentacle is positioned to the rear of each nostril. The pelvic fins are fused and, together with their surrounding tissue. they form a suction disc or sucker. They are variable in colour, having the ability to alter their colouration to blending with the substrate they are clinging to, but normally they show a pale background with a patterning of bars and spots which can vary between dark purple to reddish brown and green. On the nape there are two bright blue ocelli, or eyespots, which are thought to be defensive and to confuse predators. They grow to in standard length. Distribution ''Lepadogaster purpurea'' occurs in the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Predation
Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common List of feeding behaviours, feeding behaviours that includes parasitism and micropredation (which usually do not kill the Host (biology), host) and parasitoidism (which always does, eventually). It is distinct from Scavenger, scavenging on dead prey, though many predators also scavenge; it overlaps with Herbivore, herbivory, as Seed predation, seed predators and destructive frugivores are predators. Predation behavior varies significantly depending on the organism. Many predators, especially carnivores, have evolved distinct hunting strategy, hunting strategies. Pursuit predation involves the active search for and pursuit of prey, whilst ambush predation, ambush predators instead wait for prey to present an opportunity for capture, and often use stealth or aggressive mimicry. Other predators are opportunism, opportunistic or om ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Latitude
In geography, latitude is a geographic coordinate system, geographic coordinate that specifies the north-south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from −90° at the south pole to 90° at the north pole, with 0° at the Equator. Parallel (latitude), Lines of constant latitude, or ''parallels'', run east-west as circles parallel to the equator. Latitude and longitude are used together as a coordinate pair to specify a location on the surface of the Earth. On its own, the term "latitude" normally refers to the ''geodetic latitude'' as defined below. Briefly, the geodetic latitude of a point is the angle formed between the vector perpendicular (or ''Normal (geometry), normal'') to the ellipsoidal surface from the point, and the equatorial plane, plane of the equator. Background Two levels of abstraction are employed in the definitions of latitude and longitude. In the first step the physical surface i ...

Atlantic
The Atlantic Ocean is the second largest of the world's five oceanic divisions, with an area of about . It covers approximately 17% of Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an age of exploration and colonization of the Americas by European powers, most notably Portugal, Spain, France, and the United Kingdom. From the 16th to 19th centuries, the Atlantic Ocean was the center of both an eponymou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Johann Julius Walbaum
Johann Julius Walbaum (30 June 1724 – 21 August 1799) was a German physician, natural history, naturalist and fauna taxonomist. Works Walbaum was from Greifswald. As an ichthyologist, he was the first to describe many previously unknown fish species from remote parts of the globe, such as the Barracuda, 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. Walbaum was one of the first to observe gloves as a preventative against infection in medical surgery. As early as 1767, he used gloves made from sheep intestines for vaginal exams. Legacy The Natural History Museum in Lübeck, opened in 1893, was based on Walbaum's extensive scientific collection. The museum's collection was, however, destroyed during the Bombing of Lübeck in World War II, Bombing of Lübeck. See also * References 18th-century German ...
