Yellow Irish Lord
The yellow Irish lord (''Hemilepidotus jordani'') is a species of marine ray-finned fish belonging to the family Agonidae It is found in the northern Pacific Ocean. Taxonomy The yellow Irish lord was first formally described in 1881 by the American ichthyologist Tarleton Hoffman Bean with its type locality given as Ilyulyuk Unalaska Island in the Aleutian Islands of Alaska. Bean did not idenify the identity of the person honored in the specific name but it is most likely to be David Starr Jordan. Description The mature animal is in length. Dorsal coloration consists of alternating black and yellow stripes with small white spots laterally. The ventral surface is cream-colored. The fish has 11–12 dorsal spines, 18–23 dorsal soft rays and 35 vertebrae. This species has a maximum published total length of . There is an incision in the first dorsal fin. There are thin cirri on the upper lip. Distribution and habitat ''Hemilepidotus jordani'' lives in benthopelagic marine e ...

Alaska SeaLife Center
The Alaska SeaLife Center, Alaska's premier public aquarium and Alaska's only permanent marine mammal rehabilitation facility, is located on the shores of Resurrection Bay in Seward in the U.S. state of Alaska. Open since May 1998, it is dedicated to understanding and maintaining the integrity of the marine ecosystem of Alaska through research, rehabilitation, conservation, and public education. It is the only facility in the world specifically dedicated to studying the northern marine environment and the only one designed at the outset to combine research with public education and visitor components. The Alaska SeaLife Center generates and shares scientific knowledge to promote understanding and stewardship of Alaska's marine ecosystems. The Alaska SeaLife Center project cost $55 million; Exxon Valdez oil spill settlement funds made up the $37.5 million portion of funds dedicated to research and rehabilitation. An additional $12 million was raised by selling bonds, and $1.1 mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spine (zoology)
In a zoological context, spines are hard, needle-like anatomical structures found in both vertebrate and invertebrate species. The spines of most spiny mammals are modified hairs, with a spongy center covered in a thick, hard layer of keratin and a sharp, sometimes barbed tip. Occurrence Mammals Spines in mammals include the prickles of hedgehogs and among rodents, the quills of both New World and Old World porcupines as well as the prickly fur of spiny mice, spiny pocket mice and spiny rats. They are also found on afrotherian tenrecs, marsupial spiny bandicoots and on echidnas, of the monotremes. An ancient synapsid, '' Dimetrodon'', had extremely long spines on its backbone that were joined together with a web of skin that formed a sail-like structure. Many mammalian species, like cats and fossas, also have penile spines. The Mesozoic eutriconodont mammal ''Spinolestes'' already displayed spines similar to those of modern spiny mice. Fish Spines are found in the rays o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of The Pacific Ocean
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 ...

Bathydemersal
Demersal fish, also known as groundfish, live and feed on or near the bottom of seas or lakes (the demersal zone).Walrond Carl . "Coastal fish - Fish of the open sea floor"Te Ara - the Encyclopedia of New Zealand. Updated 2 March 2009 They occupy the sea floors and lake beds, which usually consist of mud, sand, gravel or rocks. In coastal waters they are found on or near the continental shelf, and in deep waters they are found on or near the continental slope or along the continental rise. They are not generally found in the deepest waters, such as abyssal depths or on the abyssal plain, but they can be found around seamounts and islands. The word ''demersal'' comes from the Latin ''demergere'', which means ''to sink''. Demersal fish are bottom feeders. They can be contrasted with pelagic fish which live and feed away from the bottom in the open water column. Demersal fish fillets contain little fish oil (one to four percent), whereas pelagic fish can contain up to 30 percent. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kuril Islands
The Kuril Islands or Kurile Islands (; rus, Кури́льские острова́, r=Kuril'skiye ostrova, p=kʊˈrʲilʲskʲɪjə ɐstrɐˈva; Japanese: or ) are a volcanic archipelago currently administered as part of Sakhalin Oblast in the Russian Far East. It stretches approximately northeast from Hokkaido in Japan to Kamchatka Peninsula in Russia separating the Sea of Okhotsk from the north Pacific Ocean. There are 56 islands and many minor rocks. The Kuril Islands consist of the Greater Kuril Chain and the Lesser Kuril Chain. They cover an area of around , with a population of roughly 20,000. The islands have been under Russian administration since their 1945 invasion as the Soviet Union towards the end of World War II. Japan claims the four southernmost islands, including two of the three largest ( Iturup and Kunashir), as part of its territory, as well as Shikotan and the Habomai islets, which has led to the ongoing Kuril Islands dispute.

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Total Length
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.
