The Southern Bluefin Tuna is a large species of tuna found primarily in the southern hemisphere. It is known for its streamlined body and powerful swimming abilities, making it a popular target for commercial and recreational fishing. This species can grow up to 3 meters in length and weigh over 200 kilograms. Southern Bluefin Tuna are highly migratory, traveling long distances across oceans. They are often found in deep waters and are known for their rich, fatty flesh, which is prized in culinary dishes, particularly in sushi and sashimi. Due to overfishing, their populations have declined significantly, leading to conservation efforts.
