Sebastes Melanostictus
''Sebastes melanostictus'', the blackspotted rockfish, 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 northern Pacific Ocean. Taxonomy Sebastes melanostictus was first formally described in 1934 as ''Sebastodes melanostictus'' by the Japanese ichthyologist Kiyomatsu Matsubara with the type locality given as Kazusa Province in Japan. This taxon has been considered to be a synonym of the rougheye rockfish (''S. aleutianus'') but is now accepted as a valid species and both it and the rougheye rockfish are classified within the subgenus ''Zalopyr''. The specific name, ''melanostictus'' , means “black spotted”. Description ''Sebastes melanostictus'' is similar to the rougheye rockfish and both these species have eight pairs of spines on the head plus at least two infraorbital spines. The dorsal fin has 12-14 spines and 12-15 soft rays while the anal fin has 3 spines and 7 or 8 sof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Anal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...

Crab
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fresh w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mysida
Mysida is an order (biology), order of small, shrimp-like crustaceans in the malacostracan superorder Peracarida. Their common name opossum shrimps stems from the presence of a Brood pouch (Peracarida), brood pouch or "marsupium" in females. The fact that the Crustacean larvae, larvae are reared in this pouch and are not Motility, free-swimming characterises the order. The mysid's head bears a pair of stalked eyes and two pairs of antennae. The thorax consists of eight segments each bearing branching limbs, the whole concealed beneath a protective carapace and the abdomen has six segments and usually further small limbs. Mysids are found throughout the world in both shallow and deep marine waters where they can be Benthos, benthic or pelagic, but they are also important in some fresh water and brackish water, brackish ecosystems. Many benthic species make Diel vertical migration, daily vertical migrations into higher parts of the water column. Mysids are filter feeders, omnivores ...

Amphipoda
Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods range in size from and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as ''Talitrus saltator''. Etymology and names The name ''Amphipoda'' comes, via New Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and bears two pairs of antennae and one pair of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gammaridea
Gammaridea is one of the suborders of the order Amphipoda, comprising small, shrimp-like crustaceans. Until recently, in a traditional classification, it encompassed about 7,275 (92%) of the 7,900 species of amphipods described by then, in approximately 1,000 genus, genera, divided among around 125 family (biology), families. That concept of Gammaridea included almost all fresh water, freshwater amphipods, while most of the members still were marine. The group is however considered paraphyly, paraphyletic, and is under deconstruction by the amphipod taxonomists Jim Lowry, J. Lowry and A. Myers. In 2003 they moved several families from Gammaridea to join members of the former Caprellidea in a new suborder Corophiidea.A. A. Myers & J. K. Lowry (2003). "A phylogeny and a new classification of the Corophiidea Leach, 1814 (Amphipoda)".

Pandalidae
The family Pandalidae is a taxon of caridean shrimp. These species are commonly called pandalid shrimp. They are edible and have high economic value. They are characterised by the subdivided carpus of the second pereiopod and, mainly, by the lack of the chelae (claws) on the first pereiopod. This is a cold-water family, and their representation in tropical areas is made by deep-sea shrimp. The genus ''Physetocaris'', sometimes placed in this family, is now considered to be in its own family, Physetocarididae. Genera The following genera are currently classified in the family Pandalidae: *'' Anachlorocurtis'' Hayashi, 1975 *'' Atlantopandalus'' Komai, 1999 *'' Austropandalus'' Holthuis, 1952 *'' Bitias'' Fransen, 1990 *'' Calipandalus'' Komai & Chan, 2003 *'' Chelonika'' Fransen, 1997 *'' Chlorocurtis'' Kemp, 1925 *'' Chlorotocella'' Balss, 1914 *'' Chlorotocus'' A.

Benthopelagic
The demersal zone is the part of the sea or ocean (or deep lake) consisting of the part of the water column near to (and significantly affected by) the seabed and the benthos. The demersal zone is just above the benthic zone and forms a layer of the larger profundal zone. Being just above the ocean floor, the demersal zone is variable in depth and can be part of the photic zone where light can penetrate, and photosynthetic organisms grow, or the aphotic zone, which begins between depths of roughly and extends to the ocean depths, where no light penetrates. Fish The distinction between demersal species of fish and pelagic species is not always clear cut. The Atlantic cod (''Gadus morhua'') is a typical demersal fish, but can also be found in the open water column, and the Atlantic herring (''Clupea harengus'') is predominantly a pelagic species but forms large aggregations near the seabed when it spawns on banks of gravel. Two types of fish inhabit the demersal zone: those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bering Sea
The Bering Sea (, ; rus, Бе́рингово мо́ре, r=Béringovo móre) is a marginal sea of the Northern Pacific Ocean. It forms, along with the Bering Strait, the divide between the two largest landmasses on Earth: Eurasia and The Americas. It comprises a deep water basin, which then rises through a narrow slope into the shallower water above the continental shelf, continental shelves. The Bering Sea is named for Vitus Bering, a Denmark, Danish navigator in Russian service, who, in 1728, was the first European to systematically explore it, sailing from the Pacific Ocean northward to the Arctic Ocean. The Bering Sea is separated from the Gulf of Alaska by the Alaska Peninsula. It covers over and is bordered on the east and northeast by Alaska, on the west by the Russian Far East and the Kamchatka Peninsula, on the south by the Alaska Peninsula and the Aleutian Islands and on the far north by the Bering Strait, which connects the Bering Sea to the Arctic Ocean's Chukchi ...
