Type: Fish
Diet: Carnivore
Average lifespan in the wild: 15 years
Size: 6.5 ft (2 m)
Weight: 550 lbs (250 kg)
Group name: School
Did you know? In January 2001, a prime, 444-pound (201-kilogram) bluefin tuna sold in a Japanese fish market for $173,600 (¥20.2 million), a world record.
Protection status: Endangered
Size relative to a 6-ft (2-m) man:
The Atlantic bluefin tuna is one of the largest, fastest, and most gorgeously colored of all the world’s fishes. Their torpedo-shaped, streamlined bodies are built for speed and endurance. Their coloring—metallic blue on top and shimmering silver-white on the bottom—helps camouflage them from above and below. And their voracious appetite and varied diet pushes their average size to a whopping 6.5 feet (2 meters) in length and 550 pounds (250 kilograms), although much larger specimens are not uncommon.
Unfortunately for the species however, bluefin meat also happens to be regarded as surpassingly delicious, particularly among sashimi eaters, and overfishing throughout their range has driven their numbers to critically low levels.
Atlantic bluefins are warm-blooded, a rare trait among fish, and are comfortable in the cold waters off Newfoundland and Iceland, as well as the tropical waters of the Gulf of Mexico and the Mediterranean Sea, where they go each year to spawn. They are among the most ambitiously migratory of all fish, and some tagged specimens have been tracked swimming from North American to European waters several times a year.
They are prized among sport fishers for their fight and speed, shooting through the water with their powerful, crescent-shaped tails up to 43 miles (70 kilometers) per hour. They can retract their dorsal and pectoral fins into slots to reduce drag. And some scientists think the series of “finlets” on their tails may even serve to reduce water turbulence.
Bluefins attain their enormous size by gorging themselves almost constantly on smaller fish, crustaceans, squid, and eels. They will also filter-feed on zooplankton and other small organisms and have even been observed eating kelp. The largest tuna ever recorded was an Atlantic bluefin caught off Nova Scotia that weighed 1,496 pounds (679 kilograms).
Bluefin tuna have been eaten by humans for centuries. However, in the 1970s, demand and prices for large bluefins soared worldwide, particularly in Japan, and commercial fishing operations found new ways to find and catch these sleek giants. As a result, bluefin stocks, especially of large, breeding-age fish, have plummeted, and international conservation efforts have led to curbs on commercial takes. Nevertheless, at least one group says illegal fishing in Europe has pushed the Atlantic bluefin populations there to the brink of extinction.

Bluefin Tuna Extinction Agenda
Established to protect Atlantic tuna, an international fisheries group has actually driven the bluefin tuna to the brink of extinction, environmentalists announced Thursday.
The night before a meeting in Brazil of the International Commission for the Conservation of Atlantic Tunas (ICCAT), an accusation was made by environmentalists saying that the group brazenly ignored the advice of its own scientists...
Bluefin tuna they be going extinct
Bluefin tuna they be going extinct
Bluefin tuna they be going extinct
Bluefin tuna they be going extinct
Bluefin tuna put your dishes in the sink
I eat tuna, I heat pumas, I seek schooners
I reap rugers, I keep coopers.
Fish be gettin caught in nets ridiculous
We mistreat the environment, conspicuous
I tell listeners don't be so mischevous
respect ecology, reflect the pottery
we wear the wallabees, be scared? you gotta be
cuz these tuna they deserve an apology
Bluefin tuna they be going extinct
