Thunnus Alalunga
''Thunnus'' is a genus of ocean-dwelling, ray-finned bony fish from the mackerel family, Scombridae. More specifically, ''Thunnus'' is one of five genera which make up the tribe Thunnini – a tribe that is collectively known as the tunas. Also called the true tunas or real tunas, ''Thunnus'' consists of eight species of tuna (more than half of the overall tribe), divided into two subgenera. The word is the Middle Latin form of the Greek (, "tuna, ") – which is in turn derived from (, "to rush; to dart"). The first written use of the word was by Homer. Their coloring, metallic blue on top and shimmering silver-white on the bottom, helps camouflage them from above and below. Atlantic bluefin tuna, the largest member of this genus, can grow to long and weigh up to . All tunas are extremely strong swimmers, and the yellowfin tuna is known to reach speeds of up to when pursuing prey. As with all tunas, members of this genus are warm-blooded, which is a rare trait among ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Bluefin Tuna
The southern bluefin tuna (''Thunnus maccoyii'') is a tuna of the family Scombridae found in open southern Hemisphere waters of all the world's oceans mainly between 30°S and 50°S, to nearly 60°S. At up to and weighing up to , it is among the larger bony fishes. Southern bluefin tuna, like other pelagic tuna species, are part of a group of bony fishes that can maintain their body core temperature up to above the ambient temperature. This advantage enables them to maintain high metabolic output for predation and migrating large distances. The southern bluefin tuna is an opportunistic feeder, preying on a wide variety of fish, crustaceans, cephalopods, salps, and other marine animals. Environmental/physical challenges The southern bluefin tuna is a predatory organism with a high metabolic need. These are pelagic animals, but migrate vertically through the water column, up to in depth. They also migrate between tropical and cool temperate waters in the search for food. Th ...

Skipjack Tuna
The skipjack tuna (''Katsuwonus pelamis'') is a medium-sized perciform fish in the tuna family, Scombridae.

It grows up to 1 m (3 ft) in length. It is a cosmopolitan pelagic fish found in tropical and warm-temperate waters. It is a very important species for fisheries. Description It is a streamlined, fast-swimming pelagic fish, common in tropical waters throughout the world, where it inhabits surface waters in large shoals (up to 50,000 fish), feeding on fish, crustaceans, cephalopods, and mollusks. It is an important prey species for sharks and large pelagic fishes and is often used as live bait when fishing for marlin. It has no scales, except on the lateral line and the corselet (a band of large, thick scales forming a circle around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Little Tunny
The little tunny (''Euthynnus alletteratus''), also known as the false albacore, little tuna, bonita, bonito, or blue bonito, is a species of tuna in the family Scombridae. It can be found in the Atlantic Ocean and the Mediterranean and Black seas; in the western Atlantic, it ranges from Brazil to the New England states. The little tunny is a pelagic fish that can be found regularly in both offshore and inshore waters, and it is classified as a highly migratory species. The little tunny is best identified by the "worm-like" markings on its back and the dark spots appearing between its pectoral and ventral fins. Commercially, the fish is used as bait for sharks and marlin due to its high oil content and hook retention. Because of its strong "fishy" taste and the considerable effort required to prepare it, the little tunny is considered by many to be a rough fish and is not commonly eaten. However, it is sought after as a sport fish due to its line-stripping runs and hard fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euthynnus Lineatus
''Euthynnus lineatus'', the black skipjack tuna or black skipjack, is a species of ray-finned bony fish in the family Scombridae. It belongs to the tribe Thunnini, better known as the tunas. Description ''E. lineatus'' has a total of 10-15 spines in its dorsal fins with the anterior spines of the first dorsal fin being much taller than the middle spines which gives this fin a concave outline. The anal fin has 11 - 12 soft rays and it has a vertebra count of 37. Its body is almost entirely scaleless except for the lateral line and a "corselet", and there is no swim bladder. It is generally iridescent blue in colour with black markings on its back made up of 3 to 5 horizontal stripes, as well as a variable amount of black or dark grey spots above the pelvic fins. Occasional specimens have extensive longitudinal stripes of light grey on their belly while other individuals have few or no such markings.

Bullet Tuna
The bullet tuna, ''Auxis rochei'', is a species of tuna, in the family Scombridae, found circumglobally in tropical oceans, including the Mediterranean Sea, in open surface waters to depths of 50 m (164 ft). The population of bullet tuna in the western Pacific was classified as a subspecies of ''A. rochei'', ''A. rochei eudorax'', but some authorities regard this as a valid species '' Auxis eudorax''. Its maximum length is . Sometimes called bullet mackerel, the bullet tuna is a comparatively small and slender tuna. It has a triangular first dorsal fin, widely separated from the second dorsal fin, which, like the anal and pectoral fins, is relatively small. There are the usual finlets of the tuna. There is a small corselet of small scales around the pectoral region of the body. Bullet tunas are blue-black on the back with a pattern of zig-zag dark markings on the upper hind body, and silver below. The fins are dark grey. They feed on small fish, squid, plankt ...

Frigate Tuna
The frigate tuna, frigate mackerel or alagaduwa (''Auxis thazard'') is a species of tuna, in the family Scombridae, found around the world in tropical oceans. The eastern Pacific population is now regarded as a separate species by some authorities, ''Auxis brachydorax''. Parasites As most fishes, the frigate tuna harbours a number of parasites Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson ha .... Among these are a series of digeneans, which are parasititic within the intestine.
