Blue fin tuna have elongate matching speed and endurance. They can also double breasted dorsal and anal fins into the recessed slot of the fuselage to reduce the drag of the water.
Atlantic bluefin tuna (thunnus thynnus, the Atlantic bluefin tuna) is one of the largest fish species, the fastest and most splendid colours of the world. Fish torpedo shaped body, elongated line with speed and strength. Their colors-metallic blue above and white translucent silver below-help camouflage them from above and below. Volumes as voracious and diverse food has created the average size of up to 2 meters in length and 250 kg weight, although larger individuals also very much.
Unfortunately for this species, their meat is also delicious, especially those who like to eat sashimi, and the overfishing in the region sing life has led to a number of them at extremely low levels.
The Atlantic bluefin tuna is warm-blooded fish species, a trait rarely seen in the world of fish species, and very suitable for the cold waters off the coast of Newfoundland and Iceland, as well as the tropical waters in the Gulf of Mexico and Mediterranean Sea, where they come to breed every year. They are one of the most powerful migratory fish, some fish are labeled track has been recorded swimming pool from North America to European waters several times a year.
They are also the ones who sport fishing appreciate because of fighting and speed, in the water with their tail has a strong Crescent shape with speeds up to 70 km/h They can dorsal and pectoral fins close to the concave sulcus on the fuselage to reduce the suction power of the water. The scientists also think the “fins” on the tail of them may well be to reduce the level of intense motion.
Blue fin tuna have been tremendous size of them by eating the most frequent species of smaller fish, crustaceans, squid and eels. They also eat the filtering zooplankton and smaller body and also see all kelp. The Atlantic bluefin tuna, the largest ever known catch off Nova Scotia 679 kg in weight.
Humans eat bluefin tuna in centuries. However, in the 1970s, soaring prices and demand around the world, especially in Japan, and commercial fishing operations have applied the new method to detect fish and giant fat fish caught this membrane. The result is blue fin reserves, especially big fish, fish in the reproductive period, have dropped, and international conservation efforts have led to the barring of commercial fishing. Even so, at least one group said that the illegal fishing in Europe has pushed the number of Atlantic bluefin tuna in it to the brink of extinction.
