Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Macrocystis Pyrifera
''Macrocystis pyrifera'', commonly known as giant kelp or bladder kelp, is a species of kelp (large brown algae), and one of four species in the genus ''Macrocystis''. Despite its appearance, it is not a plant; it is a heterokont. Giant kelp is common along the coast of the northeastern Pacific Ocean, from Baja California north to southeast Alaska, and is also found in the southern oceans near South America, South Africa, Australia, and New Zealand. Individual algae may grow to more than long at a rate of as much as per day. Giant kelp grows in dense stands known as kelp forests, which are home to many marine animals that depend on the algae for food or shelter. The primary commercial product obtained from giant kelp is alginate, but humans also harvest this species on a limited basis for use directly as food, as it is rich in iodine, potassium, and other minerals. It can be used in cooking in many of the ways other sea vegetables are used, and particularly serves to add flavor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lessonia Trabeculata
''Lessonia trabeculata'' is a species of kelp, a brown alga in the genus '' Lessonia''. It grows subtidally off the coasts of Peru and northern and central Chile, with the closely related ''Lessonia nigrescens'' tending to form a separate zone intertidally. Lessonia trabeculata kelp have gained a great economic importance for alginate production, and its harvest has greatly intensified along the Chilean coast during past two decades Description This kelp can grow to a length of . It is distinguished from all other members of the genus by the presence of trabeculae (cross struts) in the hollow centres of the blades and stipes (stems), and by the massive and irregular holdfast by which the kelp is attached to the rocks. Distribution and habitat ''Lessonia trabeculata'' occurs in the southeastern Pacific Ocean, in the subtidal zone off the coasts of Peru and northern and central Chile. Its range extends from Antofagasta to Puerto Montt and its depth range is between . It forms sub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lessonia Nigrescens
''Lessonia nigrescens'', the grey weed or giant grey weed, is a South American kelp species in the genus '' Lessonia''. There is at least two populations of the seaweed, marked by the difference in phenolic content. There is a subtidal population with higher phenol content and an intertidal population with a lighter phenol content. The difference in the phenolic content can be explained by the herbivory selection pressure due to the sea snail ''Tegula tridentata''. UV treatment induces the production of phlorotannins that accumulate in physodes. This weed contains the phytosterol saringosterol that shows an inhibitory effect on ''Mycobacterium tuberculosis ''Mycobacterium tuberculosis'' (M. tb) is a species of pathogenic bacteria in the family Mycobacteriaceae and the causative agent of tuberculosis.

Graus Nigra
''Graus nigra'' is a species of sea chub endemic to the Pacific coast of South America, ranging from Valdivia in Chile to southern Peru. This species grows to a total length of . It is popular as a game fish. This species is the only known member of its genus, and is known locally as ''vieja negra'' (meaning “old black” in Spanish). Ecology ''Graus nigra'' is found in Chile and Peru, often in forests of giant kelp. Associated with it in this habitat are the Chilean abalone (''Concholepas concholepas''), keyhole limpets (''Fissurella'' spp.), the Chilean sea urchin ''Loxechinus albus'', and the labrid fish Galápagos sheephead (''Semicossyphus darwini''). Other carnivorous fish in the kelp forest include the Peruvian morwong (''Cheilodactylus variegatus''), the Chilean sandperch (''Pinguipes chilensis'') and the Cape redfish (''Sebastes capensis''); also present in this habitat is the herbivorous '' Aplodactylus punctatus''.

Scorpidinae
The Scorpidinae, commonly known as halfmoons, knifefishes, and sweeps, are a subfamily of the family Kyphosidae, the sea chubs, a family of marine fish in the order Perciformes. The Scorpidinae are distributed throughout the Pacific and east Indian Oceans, with species occurring in the waters of North America, South America, Asia, Australia, and numerous islands. Most inhabit the continental shelf in shallow rock and kelp reefs and deeper offshore reefs, whilst others are found well offshore in a pelagic setting. Most of the Scorpidinae are carnivorous, taking a variety of small crustaceans, although some are partly herbivorous. A number of the larger species are fished commercially and recreationally, and are considered good table fish. Classification Fishbase lists 12 species in 5 genera under the subfamily Scorpidinae, the genera are set out below * ''Bathystethus'' Gill, 1893 * ''Labracoglossa'' Peters, 1866 * ''Medialuna'' Jordan & Fesler, 1893 * ''Neoscorpis'' J.L.B.

Fish Of Chile
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and Chondrichthyes, 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 vertebrate, 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 placodermi, 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 ...
