Semicossyphus Darwini
''Semicossyphus darwini'' is a species of ray-finned fish native to the tropical eastern Pacific Ocean. Common names include the Chilean sheepshead wrasse, the goldspot sheepshead or the Galapagos sheepshead wrasse. Description This is a large wrasse, with a maximum length of . The dorsal fin has twelve spines and ten soft rays while the anal fin has three spines and twelve soft rays. Distribution and habitat ''S. darwini'' is native to the tropical eastern Pacific Ocean. Its range includes the Galápagos Islands and on the coast of South America, extends from Ecuador southward through Peru to northern Chile. It is normally found among seaweed, including deep-water kelp forests, and its depth range is from . Ecology The strong sharp teeth provide evidence of its diet as a benthic predator, and this is confirmed by the stomach contents which include fragments of shells and other coarse calcareous debris as well as detritus. Other large carnivorous fish dwelling in the kelp forest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leonard Jenyns
Leonard Jenyns (25 May 1800 – 1 September 1893) was an English clergyman, author and naturalist. He was forced to take on the name Leonard Blomefield to receive an inheritance. He is chiefly remembered for his detailed phenology observations of the times of year at which events in natural history occurred. Personal life Jenyns was born in 1800 at No. 85 Pall Mall, London, the home of his maternal grandfather. He was the youngest son of George Leonard Jenyns of Bottisham Hall, Cambridgeshire, a magistrate, landowner and a prebendary of Ely Cathedral. His mother Mary (1763–1832) was the daughter of Dr. William Heberden (1710–1801). His father had inherited the Bottisham Hall property on the death of his distant cousin Soame Jenyns (1704–1787). By 1812, Jenyns began to study natural history encouraged by his great uncle. He went to Eton in 1813 where he read, and was inspired by Gilbert White's '' Natural History of Selborne''. In 1817 Jenyns was introduced to Sir Jos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graus Nigra

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 ...

Data Deficient
A data deficient (DD) species is one which has been categorized by the International Union for Conservation of Nature (IUCN) as offering insufficient information for a proper assessment of conservation status to be made. This does not necessarily indicate that the species has not been extensively studied; but it does indicate that little or no information is available on the abundance and distribution of the species. The IUCN recommends that care be taken to avoid classing species as "data deficient" when the absence of records may indicate dangerously low abundance: "If the range of a taxon is suspected to be relatively circumscribed, if a considerable period of time has elapsed since the last record of the taxon, threatened status may well be justified""The Categories," in IUCN (1983).

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Niño
El Niño (; ; ) is the warm phase of the El Niño–Southern Oscillation (ENSO) and is associated with a band of warm ocean water that develops in the central and east-central equatorial Pacific (approximately between the International Date Line and 120°W), including the area off the Pacific coast of South America. The ENSO is the cycle of warm and cold sea surface temperature (SST) of the tropical central and eastern Pacific Ocean. El Niño is accompanied by high air pressure in the western Pacific and low air pressure in the eastern Pacific. El Niño phases are known to last close to four years; however, records demonstrate that the cycles have lasted between two and seven years. During the development of El Niño, rainfall develops between September–November. The cool phase of ENSO is es, La Niña, translation=The Girl, with SSTs in the eastern Pacific below average, and air pressure high in the eastern Pacific and low in the western Pacific. The ENSO cycle, including bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South American Sea Lion
The South American sea lion (''Otaria flavescens'', formerly ''Otaria byronia''), also called the southern sea lion and the Patagonian sea lion, is a sea lion found on the western and southeastern coasts of South America. It is the only member of the genus ''Otaria''. The species is highly sexually dimorphic. Males have a large head and prominent mane. They mainly feed on fish and cephalopods and haul out on sand, gravel, rocky, or pebble beaches. In most populations, breeding males are both territorial and harem holding; they establish territories first and then try to herd females into them. The overall population of the species is considered stable, estimated at 265,000 animals. Naming The South American sea lion was classified as ''Otaria flavescens'' by George Shaw in 1800 and as ''Otaria byronia'' by Henri Marie Ducrotay de Blainville in 1820. The two nomenclatures were historically used interchangeably, but ''O. flavescens'' has become the preferred name. The species is ...

Marine Otter
The marine otter (''Lontra felina'') is a rare and relatively unknown South American mammal of the weasel family (Mustelidae). The scientific name means "otter cat", and in Spanish, the marine otter is also often referred to as : "marine cat". The marine otter (while spending much of its time out of the water) only lives in saltwater, coastal environments and rarely ventures into freshwater or estuarine habitats. This saltwater exclusivity is unlike most other otter species, except for the almost fully aquatic sea otter (''Enhydra lutris'') of the North Pacific. Description The marine otter is one of the smallest otters and the smallest marine mammal, measuring from the nose to the tip of the tail and weighs . The tail measures . Its fur is coarse, with guard hairs measuring up to in length covering dense, insulating underfur. The marine otter is dark brown above and on the sides, and fawn on the throat and underside. The marine otter has webbed paws and strong claws. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sebastes Capensis
''Sebastes capensis'', the false jacopever or Cape redfish, is a species of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae. It is found in the South Atlantic Ocean and may also occur off southern and western South America. Taxonomy and etymology ''Sebastes capensis'' was originally described by the German naturalist Johann Friedrich Gmelin in 1789 as ''Scorpaena capensis'' with the type locality given as the Cape of Good Hope. Some authorities place this species in the subgenus ''Sebastomus''. It has recently been demonstrated that the specimens from Peru and Chile are actually attributable to the closely related '' S. oculatus'' and these two similar species are sympatric in the southwestern Atlantic off Argentina. The specific name ''capensis'' refers to the type locality, the Cape of Good Hope. The common name false jacopever derives from a name given to some groupers, originally in the Dutch East Indies and then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinguipes Chilensis
