Longtail Tuna
''Thunnus tonggol'' is a species of tuna of tropical Indo-West Pacific waters. It is commonly known as the longtail tuna or northern bluefin tuna.Hutchins, B. & Swainston, R. (1986). ''Sea Fishes of Southern Australia.'' pp. 104 & 141. Allen, G. (1999). ''Marine Fishes of Tropical Australia and South-East Asia.'' p. 230. The usage of the latter name, mainly in Australia to distinguish it from the southern bluefin tuna, leads to easy confusion with '' Thunnus thynnus'' of the Atlantic and ''Thunnus orientalis'' of the North Pacific. Compared to these "true" bluefins, ''Thunnus tonggol'' is more slender and has shorter pectoral fins 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 see .... ''Thunnus tonggol'' reaches in length and in weight.

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] |
Black Skipjack Tuna
''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.

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.
