Thunnus Alalunga
The albacore (''Thunnus alalunga''), known also as the longfin tuna, is a species of tuna of the order Scombriformes. It is found in temperate and tropical waters across the globe in the epipelagic and mesopelagic zones. There are six distinct stocks known globally in the Atlantic, Pacific, and Indian oceans, as well as the Mediterranean Sea. The albacore has an elongate, fusiform body with a conical snout, large eyes, and remarkably long pectoral fins. Its body is a deep blue dorsally and shades of silvery white ventrally. Individuals can reach up to in length. Albacore are pelagic predators that eat a wide variety of foods, including but not limited to fish, crustaceans, and cephalopods. They are unique among tuna in that their primary food source is cephalopods, with fish making up a much smaller portion of their diet. Reproduction usually occurs from November to February and is oviparous. An adult female can release over two million eggs in a single cycle. Fry (juvenile fis ...

Euthynnus Affinis
''Euthynnus affinis'', the mackerel tuna, little tuna, eastern little tuna, wavyback skipjack tuna, kawakawa, or tongkol komo is a species of ray-finned bony fish in the family Scombridae, or mackerel family. It belongs to the tribe Thunnini, better known as the tunas. It is also in the genus Euthynnus of "little tunas," which includes the little tunny and the black skipjack. ''Euthynnus affinis'' formerly was known as ''Euthynnus yaito''. Description ''E. Affinis'' displays a typical tuna body shape with a slender, elongated body, and a deeply forked tail. It has a small amount of scales and 2 or more dark spots between the pelvic and pectoral fins. The first dorsal fin has 10-15 spines and is around 1/3rd of the tuna's body height. On its back, it displays 12 oblique stripes and a dark blue coloration for countershading. It can reach a maximum length of and a weight up to .

Little Tunny
The little tunny (''Euthynnus alletteratus''), also known as the little tuna, false albacore, or erroneously as the 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 ha ... [...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. It is in the genus Euthynnus of "little tunas" which includes the little tunny from the Atlantic Ocean and kawakawa, from the Indo-Pacific Ocean, which also shares some range with the black skipjack. 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.

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 Eastern 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, planktonic ...

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. Among these are a series of digenea Digenea (Gr. ''Dis'' – double, ''Genos'' – race) is a class of trematodes in the Platyhelminthes phylum, consisting of parasitic flatworms (known as ''flukes'') with a syncytial tegument and, usually, two suckers, one ventral and one or ...ns, which are parasititic within the intestine.

Slender Tuna
The slender tuna, ''Allothunnus fallai'', is a species of tuna, the only species in the genus ''Allothunnus'', found around the world in the southern oceans between latitudes 20° and 50° South, although there are two records of probable vagrants, one in Los Angeles Harbour and the other from the North Pacific subarctic gyre. It has a more elongated body than other species of tuna with which it is symaptric such as the albacore The colour is blue-black on the back with silvery greyish-white sides, however some individuals have a coppery sheen soon after capture. It has a small second dorsal and anal fins resembling a small albacore, but the slender tuna lacks the long sweeping pectoral fins characteristic of albacores. The pectoral fins and pelvic fins are purple on their distal portions and black near their bases. Its length is up to and it can weigh up to .

Atlantic Bluefin Tuna
The Atlantic bluefin tuna (''Thunnus thynnus'') is a species of tuna in the family Scombridae. It is variously known as the northern bluefin tuna (mainly when including Pacific bluefin as a subspecies), giant bluefin tuna (for individuals exceeding ), and formerly as the tunny. Atlantic bluefins are native to both the western and eastern Atlantic Ocean, as well as the Mediterranean Sea. They have become regionally extinct in the Black Sea. The Atlantic bluefin tuna is a close relative of one of the other two bluefin tuna species, the Pacific bluefin tuna. The southern bluefin tuna, on the other hand, is more closely related to other tuna species such as yellowfin tuna and bigeye tuna, and the similarities between the southern and northern species are due to convergent evolution. Atlantic bluefin tuna have been recorded at up to in weight, and rival the black marlin, blue marlin, and swordfish as the largest Perciformes.
