There are three species of bluefin tuna: Atlantic, Pacific, and Southern. The Atlantic bluefin is the largest species and the most endangered. These fish are built for speed and start hunting as soon as they hatch. Most of these tuna are caught in the Mediterranean Sea, the most important bluefin tuna fishery in the world.

While tuna provide the livelihood for many fishermen, they are being caught in huge quantities that could push the species into extinction. According to the IUCN Red List of Threatened Species, "This species has become rare relative to historical levels because of massive overfishing." Overfishing threatens the marine food chain, as bluefin tuna are near the top. These fish can sell for over a million dollars, which makes them a hot commodity in fish markets.
