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 ...

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 surf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepadogaster Candolii
''Lepadogaster candolii'', common name Connemarra clingfish, is a species of fish in the genus '' Lepadogaster''. It occurs in the Eastern Atlantic from the British Isles (off the coast of Western Scotland and South-West England and Ireland) south to Madeira and the Canary Islands and into the western Mediterranean and the Black Sea. The specific name ''candolii'' honours the Swiss botanist Augustin Pyramus de Candolle (1778-1841) and has various spellings: ''candolii'', ''candolei'', ''candollei'', and ''decandollii'', but only the first one is correct. Some workers have found that ''L. candolii'' is not closely related to the other two species in the genus '' Lepadogaster'' and have proposed the placing of this species in the revived monotypic genus ''Mirbelia'' Canestrini, 1864, at least until more definitive taxonomic studies can be undertaken. ''L. candolii'' is considered a euryecious species, meaning that it has a broad variety of living conditions and habitats that it ...

Clingfish
Clingfishes are fishes of the family Gobiesocidae, the only family in the order Gobiesociformes. These fairly small to very small fishes are widespread in tropical and temperate regions, mostly near the coast, but a few species in deeper seas or fresh water. Most species shelter in shallow reefs or seagrass beds, clinging to rocks, algae and seagrass leaves with their sucking disc, a structure on their chest. They are generally too small to be of interest to fisheries, although the relatively large '' Sicyases sanguineus'' regularly is caught as a food fish, and some of the other species occasionally appear in the marine aquarium trade. Distribution and habitat Clingfishes are primarily found near the shore in the Atlantic, Indian and Pacific Oceans, including marginal seas such as the Mediterranean, Gulf of Mexico, Caribbean and Gulf of California. The greatest species richness is in tropical and warm temperate regions, but the range of a few extends into colder waters, lik ...

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 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 eastern No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 of book. He was the first scientist to study Victor, the wild child of Aveyron, whose life inspired François Truffaut for his film ''The Wild Child''.

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Spermatozoon
A spermatozoon (; also spelled spermatozoön; ; ) is a motile sperm cell, or moving form of the haploid cell that is the male gamete. A spermatozoon joins an ovum to form a zygote. (A zygote is a single cell, with a complete set of chromosomes, that normally develops into an embryo.) Sperm cells contribute approximately half of the nuclear genetic information to the diploid offspring (excluding, in most cases, mitochondrial DNA). In mammals, the sex of the offspring is determined by the sperm cell: a spermatozoon bearing an X chromosome will lead to a female (XX) offspring, while one bearing a Y chromosome will lead to a male (XY) offspring. Sperm cells were first observed in Antonie van Leeuwenhoek's laboratory in 1677. Mammalian spermatozoon structure, function, and size Humans The human sperm cell is the reproductive cell in males and will only survive in warm environments; once it leaves the male body the sperm's survival likelihood is reduced and it may die, thereby dec ...

Antoine Gouan
Antoine Gouan (15 November 1733 – 1 September 1821) was a French naturalist who was a native of Montpellier. Gouan was a pioneer of Linnaean taxonomy in France. He began his studies in Toulouse, later returning to Montpellier, where he studied medicine at the University of Montpellier, university. Here he was a student of François Boissier de Sauvages de Lacroix (1706–1767), an ardent supporter of Carl Linnaeus. In August 1752, Gouan received his doctorate under the chairmanship of Antoine Magnol (1676–1759), and subsequently practiced medicine at Saint-Éloi Hospital in Montpellier. Soon afterwards his interest turned to natural history. In 1762 Gouan published a plant catalog of the botanical garden at Montpellier titled ''Hortus regius monspeliensis''. This publication was the first French botanical work that followed the binomial nomenclature of Linnaeus. In 1765 he penned ''Flora Monspeliaca'', and became ''titulaire'' at the Montpellier Academy. During this time perio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benthic
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from ancient Greek, βένθος (bénthos), meaning "the depths." Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at the shore line (intertidal ...

Mediterranean Sea
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. 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 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.
