Thunnus thynnus

Thunnus thynnus, commonly known as Atlantic bluefin tuna, is a large, powerful fish found in the North Atlantic Ocean and surrounding waters. It can grow over 10 feet long and weigh more than 1,000 pounds. Known for its speed and agility, it is a highly valued species for sushi and sashimi. Bluefin tuna are endothermic, meaning they can regulate their body temperature, which helps them thrive in various water depths. They are important ecologically and commercially but face pressures from overfishing, prompting conservation efforts to ensure their populations remain sustainable.
