Which bluefin species holds the record for the largest recorded weight, nearing 910 kg?
Answer
Thunnus thynnus
The Atlantic Bluefin Tuna, scientifically designated as *Thunnus thynnus*, is recognized as the largest among the three distinct bluefin species. Biological records document this species attaining weights rivaling 679 kg (1,497 lb), with historical reports suggesting maximums potentially reaching up to 910 kg (2,010 lb). This massive size potential distinguishes it from the Pacific Bluefin, which is generally smaller, typically ranging between 80 to 200 cm in length, and the Southern Bluefin, which is generally the smallest.
