The Bluefin Tuna (Thunnus thynnus) is a large, powerful predatory fish known for its remarkable size and speed. This species is found primarily in the Atlantic and Mediterranean regions, inhabiting deep, temperate waters. It is highly prized in commercial and sport fishing due to its size and value, particularly in sushi markets. Bluefin Tuna is a fast swimmer, capable of reaching speeds over 70 km/h (43 mph), and feeds mainly on smaller fish and squid. Its stock has been greatly impacted by overfishing.
