Blue on Blue

The bluefin is the largest member of the tuna family, shaped like torpedos and built for speed. Ferocious predators they feed on herring, mackerel and eels. They live up to 40 years, can weigh up to 1500 lbs and can dive deeper than 3000 feet.
Unfortunately, they are also one of the most sought after fish, with just a single fish selling for over $1.75 million.
