Bluefin tuna

As one of the most highly prized fish in Japanese sushi, bluefin tuna has been overfished and exploited. The problem is so severe that WWF has predicted that the Atlantic bluefin could be eaten into extinction by 2012. Unfortunately, the rarity of the species has only made demand for it grow. A single bluefin tuna can sell for more than $100,000 at Tokyo's famous Tsukiji fish market, and despite the animal's grim circumstances, there is still no international fishing ban in place.
