The Atlantic blue fin 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 silver white on the bottom) helps camouflage them from above and below. They have an average size of 6.5 feet and 550 pounds.
Unfortunately for them they are also delicious and may be on the brink of extinction due to overfishing. European Union ambassadors agreed to propose protecting blue fin tuna as an endangered species on March 10, a move that would effectively ban international trade in the species.
