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.
Average life span in the wild: 15 years
Size: 6.5 ft (2 m)
Weight: 550 lbs (250 kg)
Group name: School
Did you know? In January 2012, a prime, 593-lb (269-kg) bluefin tuna sold in a Japanese fish market for $736,000 (¥56.49 million), a world record.
