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 ...

Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Fish Of The Black Sea
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...

Epinephelus Marginatus
''Epinephelus marginatus'' (), the dusky grouper, yellowbelly rock cod or yellowbelly grouper, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. This species is the best known grouper species of the Mediterranean Sea and North Africa coast. Description ''Epinephelus marginatus'' is a very large, oval-bodied and large-headed fish with a wide mouth which has a protruding lower jaw. The head and upper body are coloured dark reddish brown or greyish, usually with yellowish gold countershading on the ventral surfaces; the base colour is marked by a vertical series of irregular pale greenish yellow or silvery grey or whitish blotching which is normally rather conspicuous on the body and head; the black maxillary streak varies in its markedness; dark brown median fins; distal edges of the anal and caudal fins and also often pectoral fins have narrow white terminal ...

Cleaner Fish
Cleaner fish are fish that show a specialist feeding strategy by providing a service to other species, referred to as clients, by removing dead skin, ectoparasites, and infected tissue from the surface or gill chambers. This example of cleaning symbiosis represents mutualism and cooperation behaviour, an ecological interaction that benefits both parties involved. However, the cleaner fish may consume mucus or tissue, thus creating a form of parasitism called cheating. The client animals are typically fish of a different species, but can also be aquatic reptiles (sea turtles and marine iguana), mammals (manatees and whales), or octopuses. A wide variety of fish including wrasse, cichlids, catfish, pipefish, lumpsuckers, and gobies display cleaning behaviors across the globe in fresh, brackish, and marine waters but specifically concentrated in the tropics due to high parasite density. Similar behaviour is found in other groups of animals, such as cleaner shrimps. There are two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shore Clingfish
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] |
Seagrass Meadow
A seagrass meadow or seagrass bed is an underwater ecosystem formed by seagrasses. Seagrasses are marine (saltwater) plants found in shallow coastal waters and in the brackish waters of estuaries. Seagrasses are flowering plants with stems and long green, grass-like leaves. They produce seeds and pollen and have roots and rhizomes which anchor them in seafloor sand. Seagrasses form dense underwater meadows which are among the most productive ecosystems in the world. They provide habitats and food for a diversity of marine life comparable to that of coral reefs. This includes invertebrates like shrimp and crabs, cod and flatfish, marine mammals and birds. They provide refuges for endangered species such as seahorses, turtles, and dugongs. They function as nursery habitats for shrimps, scallops and many commercial fish species. Seagrass meadows provide coastal storm protection by the way their leaves absorb energy from waves as they hit the coast. They keep coastal waters healthy ...

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. ...

Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggesting tha ...

Swiss People
The Swiss people (german: die Schweizer, french: les Suisses, it, gli Svizzeri, rm, ils Svizzers) are the citizens of Switzerland or people of Swiss abroad, Swiss ancestry. The number of Swiss nationality law, Swiss nationals has grown from 1.7 million in 1815 to 8.7 million in 2020. More than 1.5 million Swiss citizens hold multiple citizenship. About 11% of citizens Swiss abroad, live abroad (0.8 million, of whom 0.6 million hold multiple citizenship). About 60% of those living abroad reside in the European Union (0.46 million). The largest groups of Swiss descendants and nationals outside Europe are found in the Swiss Americans, United States, Brazil and Swiss Canadian, Canada. Although the Switzerland as a federal state, modern state of Switzerland originated in 1848, the period of romantic nationalism, it is not a nation-state, and the Swiss are not a single ethnic group, but rather are a Confederation, confederacy (') or ' ("nation of will", "nation by choice", tha ...
