Amberjacks
Amberjacks are Atlantic and Pacific fish in the genus ''Seriola'' of the family Carangidae. They are widely consumed across the world in various cultures, most notably for Pacific amberjacks in Japanese cuisine; they are most often found in the warmer parts of the oceans. There are many variations of amberjack, including greater amberjack (Atlantic), lesser amberjack (Atlantic), Almaco jack (Pacific), yellowtail (Pacific), and the banded rudderfish (Atlantic). Though most of the Seriola species are considered "amberjacks", the species Seriola hippos (samson fish) is not. Atlantic types Greater amberjacks Greater amberjacks, ''Seriola dumerili'', are the largest of the jacks. They usually have dark stripes extending from nose to in front of their dorsal fins. They have no scutes and soft dorsal bases less than twice the length of the anal fin bases. They are usually 18 kg (40 pounds) or less, and are found associated with rocky reefs, debris, and wrecks, typica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seriola Dumerili
The greater amberjack (''Seriola dumerili''), also known as the allied kingfish, great amberfish, greater yellowtail, jenny lind, Sea donkey, purplish amberjack, reef donkey, rock salmon, sailors choice, yellowtail, and yellow trevally, is a species of predatory ray-finned fish in the family Carangidae, the jacks and pompanos. It is found in temperate, subtropical, and tropical seas around the world. It is a popular quarry species for recreational fisheries and is important in commercial fisheries. It is the largest species in the family Carangidae. Description The ''greater amberjack'' is a large predatory fish which has a body colouring which varies from brownish to bluish-grey on the dorsal surfaces contrasting with the silvery-white underparts. A diagonal sooty stripe starts at the snout and runs along the centre of the back dorsal fin; another dark stripe runs from the upper jaw, across the eye to in front of the first dorsal fin. Some fish may show a light yellow to reddish- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squid
True squid are molluscs with an elongated soft body, large eyes, eight arms, and two tentacles in the superorder Decapodiformes, though many other molluscs within the broader Neocoleoidea are also called squid despite not strictly fitting these criteria. Like all other cephalopods, squid have a distinct head, bilateral symmetry, and a mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius (cephalopod), gladius or pen, made of chitin. Squid diverged from other cephalopods during the Jurassic and occupy a similar role to teleost fish as open water predators of similar size and behaviour. They play an important role in the open water food web. The two long tentacles are used to grab prey and the eight arms to hold and control it. The beak then cuts the food into suitable size chunks for swallowing. Squid are rapid swimmers, moving by Aquatic locomotion#Jet propulsion, jet propulsion, and largely locate their ...

Benthic
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from ancient Greek, βένθος (bénthos), meaning "the depths." Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at the shore line (intertidal ...

Pelagic
The pelagic zone consists of the water column of the open ocean, and can be further divided into regions by depth (as illustrated on the right). The word ''pelagic'' is derived . The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom. Conditions in the water column change with depth: pressure increases; temperature and light decrease; salinity, oxygen, micronutrients (such as iron, magnesium and calcium) all change. Marine life is affected by bathymetry (underwater topography) such as the seafloor, shoreline, or a submarine seamount, as well as by proximity to the boundary between the ocean and the atmosphere at the ocean surface, which brings light for photosynthesis, predation from above, and wind stirring up waves and setting currents in motion. The pelagic zone refers to the open, free waters away from the shore, where marine life can swim freely in any direction unhindered by topographical constraints. Th ...

Sexual Predators
Sex is the biological distinction of an organism between male and female. Sex or SEX may also refer to: Biology and behaviour * Animal sexual behaviour **Copulation (zoology) ** Human sexual activity **Non-penetrative sex, or sexual outercourse **Sex drive, a person's overall sexual drive or desire for sexual activity **Sexual intercourse, also called copulation or coitus *Gender, the distinction between male and female or masculinity and femininity within an individual's gender identity **Sex and gender distinction *Human sexuality *Mating types, a distinction of gametes, whether in anisogamous or isogamous species *Sexing, the act of discerning the sex of an animal *Sexual reproduction, a process of combining and mixing genetic traits, associated with the generation of new individuals, by means of meiosis and fertilization **Genetic recombination, the process of mixing genetic traits solely, occurring both in organisms with sexual or asexual reproduction Art and entertainment ...

Japanese Amberjack
The Japanese amberjack or yellowtail, ''Seriola quinqueradiata'', is a species of jack fish in the family Carangidae. It is native to the northwest Pacific Ocean, ranging from China (called ), Korea (called ), and Japan to Hawaii. It is greatly appreciated in Japan, where it is called ''hamachi'' or ''buri'' (). These fish are eaten either cooked or raw and are a seasonal favourite in the colder months when the meat has a higher fat content. Amberjack is typically thought of as a winter delicacy of Toyama and the Hokuriku region. Although it is frequently listed on menus as "yellowtail tuna," it is a fish of an entirely different family, the Carangidae, rather than the family Scombridae that includes tunas, mackerels, and bonitos. Some of the fish consumed are caught wild, but a substantial amount is farmed (about 120,000 tonnes per year). To populate the pens, every May, workers fish for the small wild fry (called ''mojako Fish go through various biological life cycl ...

Yellowtail Kingfish
The yellowtail amberjack, yellowtail kingfish, hiramasa or great amberjack (''Seriola lalandi'') is a large fish found in the Southern Ocean. Although previously thought to be found in all oceans and seas, recent genetic analysis restricts ''S. lalandi'' proper to the Southern Hemisphere waters. However, they are found in Northern Hemisphere waters during certain times of the year. The fish was given its name by Monsieur de Lalande, a naturalist who first informed zoologist Achille Valenciennes of the existence of this species. His reason for the use of the word ''Seriola'' (feminine diminutive form of ''seria'', a large earthenware pot) to name the fish is uncertain, but the second word ''lalandi'' was derived from his surname. Taxonomy The yellowtail amberjack was formally described in 1833 by French zoologist Achille Valenciennes from type specimens sent to him by naturalist and explorer Pierre Antoine Delalande, who is honoured in its specific name. Fishbase includes po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sharks
Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However, the term "shark" has also been used to refer to all extinct members of Chondrichthyes with a shark-like morphology, such as hybodonts and xenacanths. The oldest modern sharks are known from the Early Jurassic. They range in size from the small dwarf lanternshark (''Etmopterus perryi''), a deep sea species that is only in length, to the whale shark (''Rhincodon typus''), the largest fish in the world, which reaches approximately in length. Sharks are found in all seas and are common to depths up to . They generally do not live in freshwater, although there are a few known exceptions, such as the bull shark and the river shark, which can be found in both seawater and freshwat ...

Pilot Fish
The pilot fish (''Naucrates ductor'') is a carnivorous fish of the trevally, or jackfish family, Carangidae. It is widely distributed and lives in warm or tropical open seas. Description The pilot fish congregates around sharks, rays, and sea turtles, where it eats ectoparasites on, and leftovers around the host species; younger pilot fish are usually associated with jellyfish and drifting seaweeds. They are also known to follow ships, sometimes for long distances; one was found in County Cork, Ireland, and many pilot fish have been sighted on the shores of England. Their fondness for ships led the ancients to believe that they would navigate a ship to its desired course. The pilot fish's color is between dark blue and blackish-silver, with the belly being lighter in color.Eschmeyer & Herald 1999, p. 208. The pilot fish is also known to have a temporary variation of color when excited; its dark-colored bars disappear, and its body turns silvery-white, with three broad blue patc ...
