Notes on verification

FishBase, a peer-reviewed source, lists max published weight at 3,000 kg, and multiple derivative sources repeat this figure. However, other reputable sources (Oceana, Florida Museum, American Oceans) cite lower maximums (1,350–2,300 kg), and the best-documented specimen weighed ~2,268 kg, suggesting 3,000 kg is a theoretical/rounded upper bound rather than a verified record.
